myeclipse maven 打成jar包 对要执行的main方法暴露出去，通过java -jar 命令后跟打包好的jar文件回车就可以执行暴露的main线程方法

在该maven项目的pom.xml中添加：

<plugin>  
        <artifactId>maven-assembly-plugin</artifactId>  
        <configuration>  
            <archive>  
                <manifest>  
                    <mainClass>com.xha.db.service.DBService</mainClass>  
                </manifest>  
            </archive>  
            <descriptorRefs>  
                <descriptorRef>jar-with-dependencies</descriptorRef>  
            </descriptorRefs>  
        </configuration>  
    </plugin>

1.右键点击maven项目，在Run As 中>Maven clear,先清理下，可能会出错，不用管

2.在菜单栏目中，如：file、edit、source、Refactor、Navigate、project、Myeclipse、Mobile、Search、Run、Windows、Help找到project>clear,清除该项目，为什么要这步，不直接执行3和4，我这边试过了，不clear，在WEB-INF下的class 所有的.java文件不会自动编译修改

3.右键点击maven项目，在Run As 中>Maven install

4.右键点击maven项目，在Run As 中>Maven build会出现窗口，在Goals 输入框中输入compile assembly:single 点击run按钮即可，在target包下找到*****jar-with-dependencies.jar,该jar包就是我们打包后所需要的jar文件
