搭建步骤如下

一、新建maven项目，配置环境，测试是否配置成功

二、整合spring+mybatis，添加ApplicationContext.xml文件，修改pom.xml,，并连接mysql，测试是否搭建成功

三、整合springmvc，添加springmvc-servlet.xml文件，修改调整，测试是否搭建成功

当然下面也会附上详细的搭建过程！

项目结构一览

现在开始体验！！!

一、新建maven项目

1、新建项目，然后修改几个配置，修改完如下：

![369554-20170716160607066-2146139369.jpg][]

![369554-20170716160620503-287790196.jpg][]

2、添加Dynamic Web Module

![369554-20170716160644082-2050666777.jpg][]

Apply后，查看项目结构可以看到多了个WebContent

![369554-20170706145117487-1442772231.jpg][]

3、将WebContent下的两个文件复制到src/main/webapp下，然后将WebContent整个删掉

![369554-20170706145137112-224049749.jpg][]

4、修改Deployment Assembly，只留下下面几个

![369554-20170706145630284-1028347052.jpg][]

新增/src/main/webapp，步骤Add->Floder->src->main->webapp->finish

![369554-20170706145951269-1708883607.jpg][]

5、测试，在src/main/webapp下，新建一个index.jsp文件

![复制代码][copycode.gif]

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>hello
    </body>
    </html>

![复制代码][copycode.gif]

修改web.xml

![复制代码][copycode.gif]

运行tomcat，访问：http://localhost:8888/SSM01/，页面显示“hello”

![369554-20170716170156707-255502917.jpg][]

到此，第一步骤完成！！！

二、整合Spring+MyBatis

1、修改pom.xml，加载项目需要的jar

![ContractedBlock.gif][]  pom.xml

2、数据库准备

新建数据表tb\_book，添加测试数据

![369554-20170706151426597-1075818903.jpg][]

3、新建包和类

![369554-20170716162023160-2054273975.jpg][]

（1）添加实体类Book

![复制代码][copycode.gif]

package com.lmei.ssm.entity;
    
    public class Book {
    
        private int id;
        private String bookName;
    
        public int getId() {
            return id;
        }
    
        public void setId(int id) {
            this.id = id;
        }
    
        public String getBookName() {
            return bookName;
        }
    
        public void setBookName(String bookName) {
            this.bookName = bookName;
        }
        
        @Override
        public String toString() {
            return this.getId()+"\t"+this.getBookName();
        }
    }

![复制代码][copycode.gif]

（2）添加Dao，BookDao

![复制代码][copycode.gif]

package com.lmei.ssm.dao;
    
    import java.util.List;
    import com.lmei.ssm.entity.Book;
    
    public interface BookDao {
    
        public List<Book> getAllBook();
    }

![复制代码][copycode.gif]

（3）添加service，BookService

![复制代码][copycode.gif]

package com.lmei.ssm.service;
    
    import java.util.List;
    import com.lmei.ssm.entity.Book;
    
    public interface BookService {
    
        public List<Book> getAllBook();
    }

![复制代码][copycode.gif]

（4）添加impl，BookServiceImpl实现BookService

![复制代码][copycode.gif]

package com.lmei.ssm.impl;
    
    import java.util.List;
    import javax.annotation.Resource;
    import org.springframework.stereotype.Service;
    
    import com.lmei.ssm.dao.BookDao;
    import com.lmei.ssm.entity.Book;
    import com.lmei.ssm.service.BookService;
    
    @Service public class BookServiceImpl implements BookService{
       @Resource
        BookDao bookDao;
        public List<Book> getAllBook() {    
            return bookDao.getAllBook();
        }
    }

![复制代码][copycode.gif]

（5）添加BookMapper

![复制代码][copycode.gif]

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="com.lmei.ssm.dao.BookDao">
        <select id="getAllBook" parameterType="int" resultType="Book">
            select * from tb_book 
        </select>
    </mapper>

![复制代码][copycode.gif]

4、添加ApplicationContext.xm和db.propertiesl文件，并注册映射

![369554-20170716161619753-1900941661.jpg][]

ApplicationContext.xml

![复制代码][copycode.gif]

<?xml version="1.0" encoding="UTF-8"?>
      
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

            http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">
    
        
        <context:property-placeholder location="classpath:db.properties" />
    
        
        <bean id="jdbcDataSource"
            class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${jdbc.driver}" />
            <property name="url" value="${jdbc.url}" />
            <property name="username" value="${jdbc.username}" />

        </bean>
        
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="jdbcDataSource" />

        </bean>
        
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
            
            <property name="basePackage" value="com.lmei.ssm.dao"></property>

        <context:component-scan base-package="com.lmei.ssm">
            <context:exclude-filter type="aspectj" expression="com.lmei.ssm.dao.*"/>
        </context:component-scan>
        <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
    </beans>

![复制代码][copycode.gif]

db.properties

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
    jdbc.username=root
    jdbc.password=123456

5、添加测试类

![369554-20170716164036785-1253609275.jpg][]

TestMyBatisSpring

![复制代码][copycode.gif]

package com.lmei.ssm.test;
    
    import static org.junit.Assert.assertNotNull;
    import java.util.List;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import com.lmei.ssm.dao.BookDao;
    import com.lmei.ssm.entity.Book;
    
    public class TestMyBatisSpring {
        @Test
        public void test() {
            //初始化容器
            ApplicationContext ctx=new ClassPathXmlApplicationContext("ApplicationContext.xml");
            //获得bean     
            BookDao bookDao = ctx.getBean(BookDao.class);
            //访问数据库
            List<Book> books = bookDao.getAllBook();
            for (Book book : books) {
                System.out.println(book.getBookName());
            }
            assertNotNull(books);
        }
    }

![复制代码][copycode.gif]

Run As->JUnit Test

![369554-20170716164403707-1683405781.jpg][]

到此，第二步完成Spring+MyBatis+Mysql！！！

三、整合springmvc

1、修改实体类Book

![复制代码][copycode.gif]

package com.lmei.ssm.entity;
    
    import java.io.Serializable; public class Book implements Serializable {
        private static final long serialVersionUID = 1L; private int id;
        private String bookName;
    
        public int getId() {
            return id;
        }
    
        public void setId(int id) {
            this.id = id;
        }
    
        public String getBookName() {
            return bookName;
        }
    
        public void setBookName(String bookName) {
            this.bookName = bookName;
        }
    
        @Override
        public String toString() {
            return "id：" + getId() + "，bookName：" + getBookName() ;
        }
    
    }

![复制代码][copycode.gif]

2、在WEB-INF下新建一个文件夹view，然后在里面新建hello.jsp文件，用来测试springmvc是否搭建成功

路径webapp/WEB-INF/view/hello.jsp

![复制代码][copycode.gif]

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <%-- <%@ page isELIgnored="false" %> --%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
        <p>${message}</p>
    </body>
    </html>

![复制代码][copycode.gif]

3、新建一个controller，HelloWorld.java

![369554-20170717182829191-735729513.jpg][]

HelloWorld.java代码：

![复制代码][copycode.gif]

package com.lmei.ssm.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    //@Controller是为了让Spring IOC容器初始化时自动扫描到；
    //@RequestMapping是为了映射请求路径
    @Controller
    @RequestMapping("/Hello")
    public class HelloWorld {
        @RequestMapping("/SayHello")   
        public String SayHello(Model model) {        
            model.addAttribute("message", "Hello Spring MVC!");
           System.out.println(model.containsAttribute("message")); //是否成功赋值
    return "hello";
        }   
    }

![复制代码][copycode.gif]

4、添加springmvc-servlet.xml

![复制代码][copycode.gif]

5、修改web.xml

![复制代码][copycode.gif]

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
        id="WebApp_ID" version="3.0">
    
        <welcome-file-list>
            <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:ApplicationContext.xml</param-value>
        </context-param>
    
        <servlet>
            <servlet-name>springmvc</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath*:springmvc-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
        
        <filter>
            <filter-name>characterEncodingFilter</filter-name>
            <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
            <init-param>
                <param-name>encoding</param-name>
                <param-value>UTF-8</param-value>
            </init-param>
            <init-param>
                <param-name>forceEncoding</param-name>
                <param-value>true</param-value>
            </init-param>
        </filter>
        <filter-mapping>
            <filter-name>characterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
    
    </web-app>

![复制代码][copycode.gif]

之前在测试过程中，不小心把<url-pattern>/ 写错成 /\*，导致springmvc把\*.jsp,\*.sql,\*.txt都当做txt处理，访问页面时，直接在浏览器加载了jsp源码。

导致测试页面hello.jsp中的$\{message\}一直取不到Controller传过来的值。

<servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            <url-pattern>/</url-pattern>
    </servlet-mapping>

6、测试，项目右键->Run As->Run On Server->Tomcat...

运行成功后，访问：http://localhost:8888/SSM01/Hello/SayHello

控制台输出：输出true，表示$\{message\}赋值成功

![369554-20170717184633972-1459225449.jpg][]

浏览器输出：

![369554-20170717184725347-676313125.jpg][]

到此，SpringMVC搭建成功 ！！！

继续整合！！！

7、在controller包下，新建一个BookController

![复制代码][copycode.gif]

package com.lmei.ssm.controller;
    
    import java.util.List;
    
    import javax.annotation.Resource;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import com.lmei.ssm.entity.Book;
    import com.lmei.ssm.service.BookService;
    
    @Controller @RequestMapping("/Book")
    public class BookController {
    
        @Resource
        BookService bookService;
    
       @RequestMapping("/getAllBook")
        public String getAllBook(Model model) {
            List<Book> books = bookService.getAllBook();
            for (Book book : books) {
                System.out.println(book.getBookName());
            }
            
            model.addAttribute("books", books);
            return "Book/index";
        }
    }

![复制代码][copycode.gif]

8、在WEB-INFO/view下新建一个文件夹Book，然后在文件夹内添加index.jsp

![369554-20170717193527581-65889988.jpg][]

Book/index.jsp代码：

![复制代码][copycode.gif]

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
    <!DOCTYPE html>
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>图书管理</title>
    </head>
    <body>
        <div>
            <h3 class="title"><span>图书管理</span></h3>       
            <table border="1" width="30%" class="tab">
                <tr>               
                    <th>编号</th>
                    <th>书名</th>                               
                </tr>
                <c:forEach var="book" items="${books}">
                    <tr>                  
                        <td>${book.id}</td>
                        <td>${book.bookName}</td>                                   
                    </tr>
                </c:forEach>
            </table>    
        </div>
    </body>
    </html>

![复制代码][copycode.gif]

9、测试

运行服务器，在浏览器访问：http://localhost:8888/SSM01/Book/getAllBook

![369554-20170717193843863-1760570986.jpg][]

到此，完成SpringMVC+Spring+MyBatis的整合！！！
