虽然Struts2 的版本到2.3.16.3了,但是基本配置不变。
和2.1.x一样,首先把必要的jar包拷贝到项目的libs目录。
需要的jar包:
如果不确定用到哪些包,可以先运行Struts源码包里面的几个案例。struts2-blank,struts2-mailreader,struts2-portlet,struts2-rest-showcase,struts2-showcase。然后到该项目的目录下拷贝lib下的jar包即可。还有,配置文件也是一样,如,web.xml和struts.xml。
以struts2-blank为例。
lib:以下是本项目需要的jar包。[注:只是搭建一个简单的Struts2环境而已,基本的请求处理,拦截器什么的都是可以用的,就以下包就可以了]

然后是struts.xml配置:[注:在classes文件夹下的根目录下]
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <default-action-ref name="index" /> <global-results> <result name="error">/error.jsp</result> </global-results> <global-exception-mappings> <exception-mapping exception="java.lang.Exception" result="error"/> </global-exception-mappings> <action name="index"> <result type="redirectAction"> <param name="actionName">HelloWorld</param> <param name="namespace">/example</param> </result> </action> </package> <include file="example.xml"/> <!-- Add packages here --> </struts>
文件中引入的example.xml文件:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="example" namespace="/example" extends="default"> <action name="HelloWorld" class="example.HelloWorld"> <result>/example/HelloWorld.jsp</result> </action> <action name="Login_*" method="{1}" class="example.Login"> <result name="input">/example/Login.jsp</result> <result type="redirectAction">Menu</result> </action> <action name="*" class="example.ExampleSupport"> <result>/example/{1}.jsp</result> </action> <!-- Add actions here --> </package> </struts>
然后以上配置就可以让struts2工作了。
