　　　多模块项目的结构，“erpt-test” 是主项目，“erpt-parent”是所有子模块的parent。

Maven 多模块项目在eclipse下面热部署（Tomcat7、Jetty）

  1. Tomcat7 配置： 在“erpt-test”的POM里配置 
     1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

 3   <groupId>com.sgm.erpt</groupId>
 4   <artifactId>erpt-test</artifactId>
 5   <version>0.0.1-SNAPSHOT</version>
 6   <packaging>pom</packaging>
 7   <modules>

19       <module>erpt-web</module>
20   </modules>
21       
22     <build>
23         <plugins>
24             <plugin>
25                 <groupId>org.apache.tomcat.maven</groupId>
26                 <artifactId>tomcat7-maven-plugin</artifactId>
27                 <version>2.0-beta-1</version>
28                 <configuration>
29                     <port>9080</port>
30                     <path>/</path>
31                     <contextFile>D:/workspace_maven_test/erpt-test/erpt-web/src/main/resources/tomcatconf/context.xml</contextFile>
32                     <contextReloadable>true</contextReloadable>
33                     <useTestClasspath>false</useTestClasspath>
34                 </configuration>
35                 <dependencies>
36                     <dependency>
37                       <groupId>com.oracle</groupId>
38                       <artifactId>ojdbc14</artifactId>
39                       <version>xe</version>
40                     </dependency>
41                 </dependencies>
42             </plugin>
43         </plugins>
44     </build>
45 </project>

    其中contextFile主要配置的是JNDI数据源的

     1 <?xml version="1.0" encoding="UTF-8"?>

18 
19 <Context reloadable="false">
20 
21     <!-- Default set of monitored resources -->
22     <WatchedResource>WEB-INF/web.xml</WatchedResource>
23     
24     <!-- Uncomment this to disable session persistence across Tomcat restarts -->
25     <!--
26     <Manager pathname="" />

28 
29     <!-- Uncomment this to enable Comet connection tacking (provides events
30          on session expiration as well as webapp lifecycle) -->
31     <!--
32     <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
33     -->
34 
35 <Resource
36 name="jdbc/UM"
37 type="javax.sql.DataSource"
38 username="OWAVT"
39 password="password"
40 driverClassName="oracle.jdbc.driver.OracleDriver"
41 url="jdbc:oracle:thin:@127.0.0.1:1521:XE" />
42 
43 </Context>

    配置插件后会在项目的War项目的Target生成一个tomcat的文件夹，里面有个tomcat-users.xml文件

     1 <?xml version='1.0' encoding='utf-8'?>

17 -->
18 <tomcat-users>
19 
20   <role rolename="tomcat"/>
21   <role rolename="UMRole"/>
22   <user username="tomcat" password="tomcat" roles="tomcat"/>
23   <user username="both" password="tomcat" roles="tomcat,role1"/>
24   <user username="test01" password="password" roles="UMRole"/>
25 
26 </tomcat-users>

    最后在M2E里配置

    Maven 多模块项目在eclipse下面热部署（Tomcat7、Jetty）

  2. run-jetty-run插件， run-jetty-run是一个用jetty运行/调试Web项目的Eclipse插件，通过M2E插件结合Maven使用简直就是Web项目调试神器。如果用tomcat什么的，想要在Eclipse里面直接调试使用Maven管理的多模块项目简直是一件折磨死人的事情，用RJR什么都不用配置，直接项目右键-->DEBUG AS-->Run jetty就行了，
