1.新建 Maven 项目

        Eclipse 的 Package Explorer 视图下右击 -> New -> Maven -> Maven Project -> Next -> Select project name and location 对话框直接点 Next -> Select an Archetype 对话框，Catalog 选择 "All Catalogs"，Filter 选择 Group Id 为 "org.apache.maven.archetypes"、Artifact Id 为 "maven-archetype-quickstart"、Version 为 "1.1" 的那个，点 Next -> Enter an artifact id 对话框，Group Id 输入项目组 "mia"，Artifact Id 输入 "noti-service"(最好是你的项目名)，Version 输入版本号 "1.0.0"，Package 输入主干包名 "com.defonds.noti"，点击 Finish，新的 Maven 项目 noti-service 生成。如下图所示：

        2.编辑 pom.xml

        根据项目的需要，引入所依赖的包。作者的 pom.xml 示例如下：

 

  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        3.新建 web.xml

        src - main 下新建目录 webapp，webapp 下新建目录 WEB-INF，WEB-INF 下新建 web.xml，如下图所示：

        根据项目的实际需要编辑 web.xml，作者的示例如下：

 

  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <web-app id="WebApp_ID" version="2.4"  
  3.     xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  64.         <session-timeout>120</session-timeout>  
  65.     </session-config>  
  66.   
  67. </web-app>  

 

 

        4.新建资源目录

        src - main 和 src - test 下分别新建 Source Folder 名为 resources：

        5.修改 .classpath

        切换至 Eclipse 的 Navigator 视图，编辑 noti-service 项目下的 .classpath 文件内容如下：

 

  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <classpath>  
  3.     <classpathentry kind="src" path="src/main/java"/>  
  4.     <classpathentry kind="src" path="src/main/resources"/>  
  5.     <classpathentry kind="src" path="src/test/java"/>  
  6.     <classpathentry kind="src" path="src/test/resources"/>  
  7.     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>  
  8.     <classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/>  
  9.     <classpathentry kind="var" path="TOMCAT_HOME/lib/servlet-api.jar"/>  
  10.     <classpathentry kind="var" path="TOMCAT_HOME/lib/jasper.jar"/>  
  11.     <classpathentry kind="var" path="TOMCAT_HOME/lib/jsp-api.jar"/>  
  12.     <classpathentry kind="var" path="TOMCAT_HOME/lib/el-api.jar"/>  
  13.     <classpathentry kind="var" path="TOMCAT_HOME/lib/annotations-api.jar"/>  
  14.     <classpathentry kind="output" path="src/main/webapp/WEB-INF/classes"/>  
  15. </classpath>  

 

 

        编辑好保存后，Package Explorer 视图下的 noti-service 如下：

        6.部署到 tomcat 下
        首先要安装 tomcat 插件，可以参考《集成 Tomcat 插件到 Eclipse 的过程》。

        安装好 tomcat 插件后，Package Explorer 视图下右击项目名，点击 Properties 打开 Properties 对话框，Tomcat -> 勾选 Is a Tomcat Project，输入 Context name 内容为 "/noti"，输入 Subdirectory to set as web application root(optional) 内容为 "/src/main/webapp"，(可以参考下图)点击 OK。

技术分享

        这时项目根目录下会有 .tomcatplugin 生成，而 %tomcat%/conf/Catalina/localhost 目录下会有 noti.xml 生成。
        7.修改 .tomcatplugin

        切换至 Eclipse 的 Navigator 视图，编辑 noti-service 项目下的 .tomcatplugin 文件内容如下：

 

  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <tomcatProjectProperties>  
  3.     <rootDir>/src/main/webapp</rootDir>  
  4.     <exportSource>false</exportSource>  
  5.     <reloadable>false</reloadable>  
  6.     <redirectLogger>true</redirectLogger>  
  7.     <updateXml>true</updateXml>  
  8.     <warLocation></warLocation>  
  9.     <extraInfo></extraInfo>  
  10.     <webPath>/noti</webPath>  
  11.     <webClassPathEntries>  
  12.         <webClassPathEntry>/noti-service/src/main/webapp/WEB-INF/classes</webClassPathEntry>  
  13.         <webClassPathEntry>org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER</webClassPathEntry>  
  14.     </webClassPathEntries>  
  15. </tomcatProjectProperties>  



 

        8.断点跟踪

        这时，你就可以单击工具栏里的小猫技术分享按钮，对自己的 JEE 项目进行断点跟踪调试了。项目最终截图如下：
