这是原文地址：http://www.cnblogs.com/kodoyang/p/Apache\_Maven\_Java\_Project.html

一、Maven安装、目录结构、cmd命令  
1.下载安装  
apache-maven-3.2.3-bin.zip  
下载：http://maven.apache.org/download.cgi

![061215078132090.jpg][]  
安装：解压，配置环境变量  
M2\_HOME=D:\\Idea\\config\\apache-maven-3.2.3  
Path+=D:\\Idea\\config\\apache-maven-3.2.3\\bin

通过执行 mvn -v 可以查看当前版本号

![复制代码][copycode.gif]

C:\Users\yuki>mvn -v Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T04:58:10+08:00) Maven home: D:\Idea\config\apache-maven-3.2.3 Java version: 1.8.0, vendor: Oracle Corporation Java home: C:\Java\jdk1.8.0\jre Default locale: zh_CN, platform encoding: GBK OS name: "windows 8.1", version: "6.3", arch: "x86", family: "dos"

![复制代码][copycode.gif]

这样，maven就安装好了

2.编译：mvn compile  
新建文件D:\\Maven\\app1-maven\\pom.xml  
http://maven.apache.org/pom.html  
复制project、modelVersion标签到文件中

![复制代码][copycode.gif]

groupId：表示项目  
artifactId：表示模块  
version：表示版本

在D:\\Maven\\app1-maven\\src下新建文件夹main，test  
新建文件D:\\Maven\\app1\\module1\\src\\main\\java\\yuki\\maven\\app1\\module1\\HelloMaven.java

![复制代码][copycode.gif]

package yuki.maven.app1.module1;
    
    public class HelloMaven
    {
        public String sayHello(String name){
            return "hello:" + name;
        }
    }

![复制代码][copycode.gif]

cmd进入文件夹D:\\Maven\\app1-maven  
执行命令：mvn compile，会看到一直在运行Downloaded

maven会根据我们的需要在网络上下载相应的内容，运行完毕后，会看到Finished，  
在模块根目录D:\\Maven\\app1\\module1下看到文件夹target，这是生成的文件

![061225092035327.jpg][]

3.测试：mvn test  
新建文件D:\\Maven\\app1\\module1\\src\\test\\java\\yuki\\maven\\app1\\module1\\TestHelloMaven.java

![复制代码][copycode.gif]

package yuki.maven.app1.module1;
    
    import org.junit.*;
    import static org.junit.Assert.*;
    
    public class TestHelloMaven
    {
        @Test
        public void testSayHello(){
            HelloMaven maven = new HelloMaven();
            String str = maven.sayHello("maven");
            assertEquals(str, "hello:maven");
            //assertEquals(str, "hello:maven1");
        }
    }

![复制代码][copycode.gif]

在pom.xml中添加依赖junit  
执行mvn test

![复制代码][copycode.gif]

通过在配置文件引入junit的jar就可以使用它编译  
把项目按照maven的要求的目录中，  
它就会自动根据pom.xml文件对项目进行编译、测试、发布等操作

通过maven就可以自动完成编译，把编译后的文件放到target中，  
在测试后，会在D:\\Maven\\app1\\module1\\target\\surefire-reports生成测试报告

D:\\Maven\\app1\\module1\\target\\surefire-reports\\yuki.maven.app1.module1.TestHelloMaven.txt

-------------------------------------------------------------------------------
    Test set: yuki.maven.app1.module1.TestHelloMaven
    -------------------------------------------------------------------------------
    Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.098 sec

4.清空：mvn clean  
执行后生成的target文件被删除了

把测试类修改为断言相等一定为假的语句  
D:\\Maven\\app1\\module1\\target\\surefire-reports\\yuki.maven.app1.TestHelloMaven.txt  
文件中，我们可以看到报错的信息

7.maven的作用  
可以把项目分成很多模块，把模块开发好，  
将来直接用dependency把模块引入进来就可以直接用了

在项目中不需要再引入jar包，我们可以把项目打成jar包  
所有的工作都可以由maven代劳

二、修改仓库路径、新建eclipse maven项目  
1.仓库：repository  
在用到jar文件或其它插件文件的时候，maven就会下载这些文件  
这些文件放在默认放在C:\\Users\\yuki\\.m2\\repository中  
当执行mvn compile的时候，  
maven就会根据pom.xml的dependencies找到可能依赖的jar  
如果仓库中不存在，就会在网络中下载，并把它放在仓库里

打开C:\\Users\\yuki\\.m2\\repository\\junit\\junit\\4.10\\junit-4.10.pom  
会看到有关这个jar包的信息

当执行mvn install后，会把生成的jar包发送至本地的仓库中  
C:\\Users\\yuki\\.m2\\repository\\yuki\\maven\\app1\\module1\\0.0.1-SNAPSHOT\\module1-0.0.1-SNAPSHOT.jar

![061245467979235.jpg][]  
所以可以通过依赖引入jar包

2.自定义仓库的位置  
把仓库放在系统盘中是不合适的，一旦重装系统，对应仓库就会消失  
全球maven的中央仓库：http://mvnrepository.com/

![061247448446905.jpg][]

打开文件$\{M2\_HOME\}\\conf\\settings.xml

搜索localRepository，看到Default: $\{user.home\}/.m2/repository

新建文件夹D:\\Idea\\maven\\repository

![复制代码][copycode.gif]

<localRepository>D:\Idea\maven\repository</localRepository>

![复制代码][copycode.gif]

在setting.xml添加<localRepository>D:\\Idea\\maven\\repository</localRepository>  
执行mvn compile，会看到文件又在重新下载  
可以把原先下载的文件的目录剪切到新的文件夹下，这样就不会重新下载了

它是怎么找到中央库的,打开文件  
D:\\Idea\\config\\apache-maven-3.2.3\\lib\\maven-model-builder-3.2.3.jar  
查看\\maven-model-builder-3.2.3.jar\\org\\apache\\maven\\model\\pom-4.0.0.xml

会看到设置了https://repo.maven.apache.org/maven2 的仓库url  
用浏览器访问这个url，会跳转到http://search.maven.org/\#browse

3.原型：mvn archetype  
maven的目录结构是确定的，  
执行 mvn archetype:generate 就会下载与这个原型相关的程序  
下载完成后，文件被存在本地工厂中  
版本号选择默认的6，groupId输入yuki.maven.app，  
artifactId输入module，version输入0.0.1-SNAPSHOT  
package默认，最后输入选择默认的Y  
最后它在执行命令的根目录下帮我们建立了一个相似的module文件夹

打开D:\\Maven\\module\\pom.xml，把junit的version改为4.10 ，删除刚刚新建的模块module  
执行 ：mvn archetype:generate  \-DgroupId=yuki.maven.app2.module1  \-DartifactId=module2  \-Dversion=0.0.1-SNAPSHOT

然后默认选择版本，选择yes后新建项目

![061258225166859.jpg][]

4.eclipse配置maven  
这是在客户端创建，怎样在eclipse里面创建  
Eclipse Kepler中已经有自带的maven  
Preferences>Maven>Installations>Add  
选择安装的maven根目录D:\\Idea\\config\\apache-maven-3.2.3  
Preferences>Maven>User Settings>Browse  
选择D:\\Idea\\config\\apache-maven-3.2.3\\conf\\settings.xml

![061304116726256.jpg][]

5.新建maven项目  
File>New>Other>Maven>Maven Project>Next>Next  
有大量的ArtifactId，这里选择maven-archetype-quickstart  
Next>填写GroupId、ArtifactId、Version、Package  
可以看到新建的maven项目

![061306080003484.jpg][]

约定优于配置  
新建Source Folder>src/main/resources，存放配置文件  
新建Source Folder>test/main/resources，存放测试配置文件

![061307148131707.jpg][]

三、新建Maven项目  
1.通过pom.xml文件引入Hibernate的jar包  
新建实体类yuki.maven.user.core.model.User，为User创建构造方法：无参构造，没有id的构造  
/user-core/src/main/java/yuki/maven/user/core/model/User.java

![复制代码][copycode.gif]

package yuki.maven.user.core.model;
    
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.Table;
    
    @Entity
    @Table(name="T_USER")
    public class User 
    {
        private int id;
        private String username;
        private String password;
        private String nickname;
        
        public User() {
        }
        public User(String username, String password, String nickname) {
            super();
            this.username = username;
            this.password = password;
            this.nickname = nickname;
        }
    
        @Id
        @GeneratedValue
        public int getId() {
            return id;
        }
        public void setId(int id) {
            this.id = id;
        }
        public String getUsername() {
            return username;
        }
        public void setUsername(String username) {
            this.username = username;
        }
        public String getPassword() {
            return password;
        }
        public void setPassword(String password) {
            this.password = password;
        }
        public String getNickname() {
            return nickname;
        }
        public void setNickname(String nickname) {
            this.nickname = nickname;
        }
        
    }

![复制代码][copycode.gif]

pom.xml中junit的版本号改为4.10

访问http://mvnrepository.com/ 搜索hibernate  
点击Core Hibernate O/RM Functionality，4.3.6.Final  
复制maven选项卡中的xml文本到dependencies标签下  
打开Console>MavenConsole，可以看到

![复制代码][copycode.gif]

14-9-2 GMT+0800下午10:41:54: [INFO] Downloaded http://repo.maven.apache.org/maven2/org/hibernate/hibernate-core/4.3.6.Final/hibernate-core-4.3.6.Final.jar

这说明Maven已下载了hibernate的依赖包，可以看到文件：  
D:\\Idea\\maven\\repository\\org\\hibernate\\hibernate-core\\4.3.6.Final\\hibernate-core-4.3.6.Final.jar  
打开Maven Dependencies，在下面可以看到已引入的Hibernate的包

![061312367665281.jpg][]

2.配置eclipse的代码提示  
自动代码提示：  
preference>Keys>搜索content>ContentAssist=Alt+/  
preference>Java>Editor>ContentAssist/AutoActivation  
把javadoc中的@ 剪切到Java中  
在编辑器中输入@ 就会自动给出提示的下拉列表

![061329237826431.jpg][]  
在User类中加入注解

3.引入oracle的驱动jar包  
http://mvnrepository.com/artifact/com.oracle/ojdbc14/10.2.0.4.0  
在pom.xml上粘贴以来后，显示报错  
打开D:\\Idea\\maven\\repository\\com\\oracle\\ojdbc14\\10.2.0.4.0  
发现没有对应的jar包，是因为访问地址404错误  
http://central.maven.org/maven2/com/oracle/ojdbc14/10.2.0.4.0/ojdbc14-10.2.0.4.0.jar

![061332051104911.jpg][]  
访问http://www.java2s.com/Code/Jar/o/ojdbc14.htm 下载ojdbc14-10.2.0.4.0.jar

在目录下执行驱动jar所在路径下执行：

mvn install:install-file -DgroupId=com.oracle  \-DartifactId=ojdbc14 -Dversion=10.2.0.4.0 -Dpackagin

pom.xml文件不再报错  
在项目中引入log4j

4.配置文件  
引入dtd文件hibernate-configuration-3.0.dtd，参照dtd的<!DOCTYPE>  
Public ID的Key上填写：\-//Hibernate/Hibernate Configuration DTD 3.0//EN  
Alternative web address：http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd  
通过这个约束在src/main/resources下新建配置文件hibernate.cfg.xml  
/hibernate-release-4.3.6.Final/documentation/manual/en-US/html\_single/index.html  
参照配置文件进行配置hibernate

![复制代码][copycode.gif]

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-configuration PUBLIC 
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd" >
    <hibernate-configuration>
        <session-factory>
            
            <property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
            <property name="connection.url">jdbc:oracle:thin:@localhost:1521:xe</property>
            <property name="connection.username">kongdy</property>
            <property name="connection.password">yuki</property>
    
            
            <property name="dialect">org.hibernate.dialect.OracleDialect</property>

            <property name="hbm2ddl.auto">update</property>
    
            
            <mapping class="yuki.maven.user.core.model.User" />
        </session-factory>
    </hibernate-configuration>

![复制代码][copycode.gif]

配置log4j.properties文件

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %p %c{1} %L -%m%n
    log4j.rootlogger=warm,stdout
    log4j.logger.org.hibernate.SQL=debug

5.新建用户访问类  
按照帮助文档中的Startup and helpers新建HibernateUtil类

/user-core/src/main/java/yuki/maven/user/core/util/HibernateUtil.java

![复制代码][copycode.gif]

package yuki.maven.user.core.util;
    
    import org.hibernate.SessionFactory;
    import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
    import org.hibernate.cfg.Configuration;
    import org.hibernate.service.ServiceRegistry;
    
    public class HibernateUtil {
    
        private static final SessionFactory sessionFactory = buildSessionFactory();
    
        private static SessionFactory buildSessionFactory() {
            try {
                // Create the SessionFactory from hibernate.cfg.xml
                Configuration configuration = new Configuration().configure();
                ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
                return configuration.buildSessionFactory(serviceRegistry);
            }
            catch (Throwable ex) {
                // Make sure you log the exception, as it might be swallowed
                System.err.println("Initial SessionFactory creation failed." + ex);
                throw new ExceptionInInitializerError(ex);
            }
        }
    
        public static SessionFactory getSessionFactory() {
            return sessionFactory;
        }
    
    }

![复制代码][copycode.gif]

新建UserDao并测试TestUserDao，  
/user-core/src/main/java/yuki/maven/user/core/dao/IUserDao.java

![复制代码][copycode.gif]

package yuki.maven.user.core.dao;
    
    import yuki.maven.user.core.model.User;
    
    public interface IUserDao {
    
        void add(User user);
        User loadByUsername(String username);
    }

![复制代码][copycode.gif]

/user-core/src/main/java/yuki/maven/user/core/dao/UserDao.java

![复制代码][copycode.gif]

package yuki.maven.user.core.dao;
    
    import org.hibernate.Session;
    
    import yuki.maven.user.core.model.User;
    import yuki.maven.user.core.util.HibernateUtil;
    
    public class UserDao implements IUserDao {
    
        public void add(User user) {
            Session session = null;
            try {
                session = HibernateUtil.getSessionFactory().getCurrentSession();
                session.beginTransaction();
                
                session.save(user);
                
                session.getTransaction().commit();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                HibernateUtil.getSessionFactory().close();
            }
        }
    
        public User loadByUsername(String username) {
            Session session = null;
            User user = null;
            try {
                session = HibernateUtil.getSessionFactory().getCurrentSession();
                session.beginTransaction();
                
    //            user = (User) session.createQuery("from User where username=?").setParameter(0, username).uniqueResult();
                user = (User) session.createQuery("from User where username=?").setParameter(0, username).list().get(0);
                
                session.getTransaction().commit();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                HibernateUtil.getSessionFactory().close();
            }
            return user;
        }
    
    }

![复制代码][copycode.gif]

/user-core/src/test/java/yuki/maven/user/core/dao/UserDaoTest.java

![复制代码][copycode.gif]

package yuki.maven.user.core.dao;
    
    import org.junit.After;
    import org.junit.Before;
    //import org.junit.Test;
    
    import yuki.maven.user.core.model.User;
    
    public class UserDaoTest {
    
        private UserDao userDao;
        
        @Before
        public void setUp() throws Exception {
    //        Class.forName("yuki.maven.user.core.util.HibernateUtil");
            userDao = new UserDao();
            System.out.println("开始测试");
        }
    
    //    @Test
        public void testAdd() {
            userDao.add(new User("username1", "password1", "用户名1"));
        }
    
    //    @Test
        public void testLoadByUsername() {
            User user = userDao.loadByUsername("username1");
            System.out.println(user.getUsername() + ", " + user.getPassword() + ", " + user.getNickname());
        }
        
        @After
        public void tearDown() {
            userDao = null;
            System.out.println("测试结束");
        }
    
    }

![复制代码][copycode.gif]

6.测试用户访问类  
pom.xml右键>Run As>Maven build…  
Main>Goals=clean test>Apply>Run

![061413221416898.jpg][]  
JRE>Installed JREs…>选择JDK的路径而不是JRE的路径  
Apply>Run，再次运行后就可以直接点击\[Alt+Shift+X,M\]的那个了

运行时会报错  
Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set  
http://www.journaldev.com/2897/solved-hibernateexception-access-to-dialectresolutioninfo-cannot-be-null-when-hibernate-dialect-not-set  
运行services.msc，打开服务OracleServiceXE，OracleXETNSListener

![061411547979448.jpg][]

必须一个一个测试，否则报出异常  
org.hibernate.service.UnknownServiceException: Unknown service requested \[org.hibernate.engine.jdbc.connections.spi.ConnectionProvider\]

四、新建其它的maven模块  
1.新建模块user-log  
pom.xml按下Ctrl+Shift+F就会自动排版  
http://mvnrepository.com/artifact/commons-logging/commons-logging/1.2  
http://mvnrepository.com/artifact/log4j/log4j/1.2.17  
对两个模块打包：user-core>Run As>clean package，user-log>Run As>clean package

/user-log/src/main/java/yuki/maven/user/log/Log.java

![复制代码][copycode.gif]

package yuki.maven.user.log;
    
    public class Log 
    {
        public static void main( String[] args )
        {
            System.out.println( "Hello World!" );
        }
    }

![复制代码][copycode.gif]

新建user-service模块，添加日志的依赖

2.隐藏变量  
$\{basedir\} 项目根目录  
$\{project.build.directory\} 构建目录，缺省为target  
$\{project.build.outputDirectory\} 构建过程输出目录，缺省为target/classes  
$\{project.build.finalName\} 产出物名称，缺省为project.artifactId− project.artifactId−\{project.version\}  
$\{project.packaging\} 打包类型，缺省为jar  
$\{project.xxx\} 当前pom文件的任意节点的内容

<dependency>
                <groupId>${project.groupId}</groupId>
                <artifactId>user-core</artifactId>
                
            </dependency>

Missing artifact yuki.maven.app1-user:maven-core:jar:0.0.1-SNAPSHOT  
本地仓库找不到，对user-core和user-log执行install命令  
再引入user-core和user-log的依赖时，对应它们的依赖也被依赖进来，被称为依赖传递  
利用引入的内容完成用户服务类

3.依赖范围  
这时，用户的访问类可能还在做开发，这里用到了easymock  
http://mvnrepository.com/artifact/org.easymock/easymock/3.2

/user-service/src/main/java/yuki/maven/user/service/IUserService.java

![复制代码][copycode.gif]

package yuki.maven.user.service;
    
    import yuki.maven.user.core.model.User;
    
    public interface IUserService 
    {
        void add(User user);
        User loadByUsername(String username);
    }

![复制代码][copycode.gif]

/user-service/src/main/java/yuki/maven/user/service/UserService.java

![复制代码][copycode.gif]

package yuki.maven.user.service;
    
    import yuki.maven.user.core.dao.IUserDao;
    import yuki.maven.user.core.model.User;
    
    public class UserService implements IUserService {
    
        private IUserDao userDao;
        public UserService(IUserDao userDao) {
            this.userDao = userDao;
        }
        
        public void add(User user) {
            userDao.add(user);
        }
    
        public User loadByUsername(String username) {
            return userDao.loadByUsername(username);
        }
    
    }

![复制代码][copycode.gif]

/user-service/src/test/java/yuki/maven/user/service/UserServiceTest.java

![复制代码][copycode.gif]

package yuki.maven.user.service;
    
    import static org.junit.Assert.*;
    import static org.easymock.EasyMock.*;
    
    import org.hibernate.cfg.CreateKeySecondPass;
    import org.hibernate.internal.util.compare.EqualsHelper;
    import org.junit.After;
    import org.junit.Before;
    import org.junit.Test;
    
    import yuki.maven.user.core.dao.IUserDao;
    import yuki.maven.user.core.model.User;
    
    public class UserServiceTest {
    
        private IUserDao userDao;
        private IUserService userService;
        private User user;
        
        @Before
        public void setUp() throws Exception {
            userDao = createStrictMock(IUserDao.class);
            userService = new UserService(userDao);
            user = new User();
        }
    
        @After
        public void tearDown() throws Exception {
            verify(userDao);
        }
    
        @Test
        public void testAdd() {
            userDao.add(user);
            expectLastCall();
            replay(userDao);
            userService.add(user);
            
        }
    
        @Test
        public void testLoadByUsername() {
            expect(userDao.loadByUsername("admin")).andReturn(user);
            replay(userDao);
            User user2 = userService.loadByUsername("admin");
            System.out.println(EqualsHelper.equals(user2, user));
        }
    
    }

![复制代码][copycode.gif]

依赖范围的取值scope，什么时候把依赖加进去  
compile：编译、打包，默认的依赖范围  
provided：编译、测试，比如servlet-api不会打包进去  
runtime：编译时不依赖，测试和运行时依赖，比如数据库驱动jar  
test：仅仅在测试的时候依赖，比如junit  
只有放在/src/test文件夹下的java文件才能使用junit

被依赖模块的scope=test的jar不会传递给依赖它的模块  
被传递过来的依赖也被称为是间接依赖

在dependency hierarchy中可以看到依赖的继承关系  
如果依赖级别相同，会依赖写在前面的依赖  
如果依赖级别不同，就会先依赖层次最浅的

可以通过dependency的子标签exclusions排除不需要继承的依赖

![复制代码][copycode.gif]

<dependency>
                <groupId>${project.groupId}</groupId>
                <artifactId>user-log</artifactId>
                
                
            </dependency>

![复制代码][copycode.gif]

这里可以解决jar包冲突问题

4.聚合  
可以在三个模块的根目录中创建一个pom.xml文件  
通过它可以集中编译项目，这个pom.xml可以什么都不用写  
在eclipse中，new maven project  
选择create a simple project(skip archetype selection)  
ArtifactId = user-aggregate，packaging = pom > Finish

打开pom.xml文件在project标签下填写modules标签

/user-aggregate/pom.xml

![复制代码][copycode.gif]

这样，对这个文件执行maven命令就是向包含的module执行maven命令

5.继承  
配置里面很多是重复的，有可能也会设置大量的常量，这些在项目里都是重复的  
可以让所有的项目继承一个根类，所有的项目继承这个类  
新建user-parent项目，选择create a simple project，packaging=pom

复制相同的内容到user-parent/pom.xml中，  
添加parent标签，同时删掉复制的内容，  
相对路径relativePath=../user-parent/pom.xml  
这时，会提示原先写的groupIdheversion有重复，可以删掉它们

依赖也是可以继承的，但是这意味着每一个项目都要加进被继承的依赖  
把user-core中的dependencies标签加在dependencyManagement中  
这样，就可以删掉user-core依赖的版本、排除信息了

\\user-parent\\pom.xml

可以把聚合文件modules也放在user-parent中  
如果把user-parent/pom.xml放在所有模块的根目录下，就需要删除路径的../  
对应的模块继承的../user-parent/pom.xml也可以改成pom.xml  
继承的是绝对路径是pom.xml文件，聚合是模块的位置

2.版本  
大版本的变化.分支的变化.更新-里程碑  
SNAPSHOT：快照版本，正在开发中  
alpha：内部测试版本  
beta：使用者使用测试  
Release(RC)：释放版本  
GeneralAvailable(GA)：正常可用的版本
