有代码更新后重新打包到tomcat再发布，是不是很烦？
看了下面的东西你就不会烦了。
SVN或者git等代码版本控制工具不说了，如果是本地开发，也可以安装一个svn server端
jenkins下载后是一个war包，
首先设置下 环境变量 JENKINS_HOME 为 c:\jenkins
拷贝到一个tomcat的webapp目录下启动tomcat保证能正常访问
http://localhost:8880/jenkins/ 多个tomcat请注意修改端口
打开后第一次没任何项目，新建一个项目 maven项目，怎么创建maven项目 请参考我的博客其他文章
必填项：
项目名称： 随意了，自己喜欢就好 O(∩_∩)O哈哈~
下面填写自己的svn cvs等信息，地址及用户名密码
往下： 请勾选 Build whenever a SNAPSHOT dependency is built 这个复选框
再往下就是配置构建成功后发布信息的，这个首先得安装一个插件
安装Deploy to container Plugin 插件，安装成功后才能自动发布
安装好后重启下服务器最好
构建后操作，选择安装好插件后的 deploy war to container，
输入target目录下生成的war包，
配置远程的tomcat，并保证可以登录到manage界面，配置的tomcat处于启动状态
注意：
tomcat默认是没有用户可以登录的 需要修改 conf下的user.xml
如下：
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user password="tomcat" roles="manager-gui,manager-script,manager-jmx,manager-status" username="tomcat"/>
</tomcat-users>
同时记得修改tomcat/conf/context.xml
<Context antiResourceLocking="true">
修改这个主要是为了解决再次部署的时候，不能删除原项目部署目录，详情可参考http://tomcat.apache.org/tomcat-7.0-doc/config/context.html 搜索 lock
配置完成，点击应用 保存
然后创建，失败是红色，具体信息看控制台，成功后的log大致如下：

打开tomcat管理页面都能看见发布的项目
同样打开这个项目也能正常访问
jdk maven配置：
如果遇见编码问题
1.增加环境变量 JAVA_TOOL_OPTIONS= -Dfile.encoding=UTF-8
2.在kenkins中增加Environment variables LANG=zh.CH.UTF-8 和 JAVA_TOOL_OPTIONS= -Dfile.encoding=UTF-8
