定义一个 package，然后其他package都继承 这个package
struts-global
就 有了这个错误处理功能了
然后再自己写个类
struts.xml
1 <constant name="struts.devMode" value="true" /> 2 <constant name="struts.enable.DynamicMethodInvocation" value="false"></constant> 3 <!-- <constant name="struts.custom.i18n.resources" value="itcast"></constant> --> 4 <package name="struts-global" namespace="/" extends="struts-default"> 5 <global-results> 6 <result name="errHandler" type="chain"> 7 <param name="actionName">errorProcessor</param> 8 </result> 9 </global-results> 10 <global-exception-mappings> 11 <exception-mapping result="errHandler" exception="java.lang.Exception"> 12 </exception-mapping> 13 </global-exception-mappings> 14 15 <action name="errorProcessor" class="cn.itcast.sh.error.ErrorProcess"> 16 17 <result>error.jsp</result> 18 </action> 19 </package>
cn.itcast.sh.error.ErrorProcess类
1 package cn.itcast.sh.error; 2 3 import com.opensymphony.xwork2.ActionContext; 4 import com.opensymphony.xwork2.ActionSupport; 5 6 public class ErrorProcess extends ActionSupport { 7 private Exception exception; 8 9 public Exception getException() { 10 return exception; 11 } 12 13 public void setException(Exception exception) { 14 this.exception = exception; 15 } 16 @Override 17 public String execute() 18 { 19 ActionContext.getContext().getValueStack().push(this.exception.getMessage()); 20 return this.SUCCESS; 21 } 22 }
其他 strut.xml中
1 <?xml version="1.0" encoding="utf-8"?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 <struts> 6 <package name="user" namespace="/" extends="struts-global"> 7 <action name="UserAction_*" method="{1}" class="cn.itcast.sh.action.UserAction"> 8 <result name="userList">/user/list.jsp</result> 9 </action> 10 11 12 </package> 13 </struts>
