Eclipse自动部署项目到Tomcat的webapps下的有效方法
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>前提：环境搭建</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>Jdk1.6.0+Tomcat7.0+Eclipse 4.2.0</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>安装路径：</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>C:JavaJdk1.6.0</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>C:JavaJre1.6.0</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>C:\Program Files\Tomcat 7.0.11</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>E:workspace 我的Eclipse的工作台</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>E:Eclipse/Eclipse.exe<wbr><wbr><span></span>Eclipse所在目录</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>第一种<wbr><wbr><span></span>把项目打包成*.War文件。比如：在Eclipse里，先创建项目login1，然后复制login1并改名为login2，增加或者修改 login2里的类文件后，为了测试下能否实现某功能，就在login2项目上，选择"Export" , 导出为WAR文件，比如命名为login2.War，然后复制这个</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>login2.WAR文件到C:Tomcat 7.0.11webapps下，停止Tomcat服务，重新启动Tomcat服务，login2.war会自动解压出一个文件夹login2，再打开http://127.0.0.1:8080/login2/index.jsp就可以访问了，测试能否实现某功能。这个方法的缺点是，如果需要修改源代码，必须重新打包修改后的war文件，复制到C:Tomcat 7.0.11webapps下并覆盖原来的login2.war，如果需要修改很多次，就需要覆盖很多次，无意义的工作很多，最好是Eclipse里每修改下 源代码，重启TOMCAT服务就可以加载新代码测试，怎样实现了，请参看第二种方法。
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>第二种<wbr><wbr><span></span>要实现的目标就是让ECLIPSE自动部署项目到tomcat的C:Tomcat 7.0.11webapps下，而不是到工作区下的.metadata.pluginsorg.eclipse.wst.server.core tmp1wtpwebapps，可以实现，方法很简单。</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>新建个Dynamic Web Project，命名为mysql，在WebContent下，新建个文件index.jsp，随便写段代码，</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
见图一
点击mysql项目名，然后点击右键Run As—》Run on Server，按照图二
的样式，点击 Next，再点Finish，见图三
Servers下，已经添加好了一个Tomcat v7.0 Server，在上面点右键，选择open，打开，见图四
Server Locations 的状态为灰色，修改不了，见图五
关键就是需要修改这里，那么怎么能修改呢？先要移除掉部署在其中的项目，见图六
Server Locations 的状态不为灰色可修改，见图七
可以修改Server Locations 的配置了。
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>配置修改3个地方：</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>1、选择"Use Tomcat installation "，默认为"Use<wbr><wbr>Workspace metadata<wbr><wbr>"，见图八；</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>2、选中"Use Tomcat insallation "后，下面一行，Server Path 自动修改为C:\Program Files\Tomcat 7.0.11（Tomcat安装路径）</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span></span>3、Deploy Path 处需要修改为"webapps" ，默认为"wtpwebapps"。</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
文件修改完，点击close，关闭。弹出对话框，选择YES，保存设置。
至此，设置完成，以后复制一个项目，只需在项目mysql，右键，选择Properties，再选择Web Project Settings修改下项目名称就可以自动部署到Tomcat的Webapps目录下了。见图九。
