Eclipse EE+MAVEN配置以及POM.XML的使用

### Eclipse EE下载 ###

Eclipse 与 Eclipse EE 是不同的产品，后者有更多的插件与管理工具  
下载页面：[http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/keplersr2][http_www.eclipse.org_downloads_packages_eclipse-ide-java-ee-developers_keplersr2]

### 安装Eclipse中的Maven插件 ###

Eclipse EE中自带Maven插件所以这一步略过

### 下载与配置Maven ###

下载页面 [http://maven.apache.org/download.cgi][http_maven.apache.org_download.cgi]

更改./conf/settings.xml中关于localRepository 的地址

<localRepository>/yourpath/</localRepository>
     
     
      
       1 
      
     
     
      
       1

添加系统环境变量  
M2\_HOME = Maven所在根目录  
path += M2\_HOME\\bin  
（在管理员模式cmd中输入mvn -v检测是否环境变量添加成功）  
然后在Window->Preference->[Java][]\->Installed JREs->Edit  
在Default VM arguments中设置  
\-Dmaven.multiModuleProjectDirectory=$M2\_HOME  
![这里写图片描述][SouthEast]

Installations->Add-> 添加Maven路径

![这里写图片描述][SouthEast 1]

User Settings->设置User Settings 为之前的/conf/settings.xml  
![这里写图片描述][SouthEast 2]

### 创建Maven项目与使用Pom.xml添加依赖 ###

![这里写图片描述][SouthEast 3]  
新建Maven Project->next->选择模板maven-archetype-quickstart  
![这里写图片描述][SouthEast 4]  
填写包名与模块名信息  
![这里写图片描述][SouthEast 5]

生成工程如下；  
![这里写图片描述][SouthEast 6]

### 例子中尝试使用Log4j ###

双击pom.xml进入pom管理页  
下方选择pom.xml标签页  
![这里写图片描述][SouthEast 7]  
如我需要添加log4j包，首先在[http://mvnrepository.com/][http_mvnrepository.com]中搜索包名，然后复制该包的描述xml  
![这里写图片描述][SouthEast 8]  
即这一段

<dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
     
     
      
       1 
       2 
       3 
       4 
       5 
      
     
     
      
       1 
       2 
       3 
       4 
       5

将这一段复制到pom.xml中`<dependencies>`中，返回Depdencies标签页，显示如下：

右键pom.xml->run as->Maven install  
第一次运行会安装一些插件，之后会把需要的依赖包下载下来

新建一个class 尝试import log4j包  
![这里写图片描述][SouthEast 10]

不出现报错则使用完整代码

import org.apache.log4j.Logger;
    /**
     *@author linbingwen
     *@2015年5月18日9:14:21
     */
    public class App {
        
        private static Logger logger = Logger.getLogger(App.class);  
    
        /** 
         * @param args 
         */  
        public static void main(String[] args) {  
            // System.out.println("This is println message.");  
    
            // 记录debug级别的信息  
            logger.debug("This is debug message.");  
            // 记录info级别的信息  
            logger.info("This is info message.");  
            // 记录error级别的信息  
            logger.error("This is error message.");  
        }  
    
    }

       23

注意log4j需要设置log4j.properties  
在对应的source folder下新建log4j.properties  
![这里写图片描述][SouthEast 11]

内容为

log4j.rootLogger=INFO,A1,R
    
    log4j.appender.A1=org.apache.log4j.ConsoleAppender
    log4j.appender.A1.layout=org.apache.log4j.PatternLayout
    log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n
    
    log4j.appender.R=org.apache.log4j.RollingFileAppender
    log4j.appender.R.File=bbscs7log.txt
    log4j.appender.R.MaxFileSize=500KB
    log4j.appender.R.MaxBackupIndex=10
