下面是struts的异常配置：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts> 
    <!-- 配置的package的name不能和主文件struts中的package名称相同 -->
	<package name="user2" extends="struts-default">
	  <global-results>
	     <result name="sql">/exception.jsp</result>
	     <result name="root">/exception.jsp</result>
	  </global-results>
	  <global-exception-mappings>
	     <exception-mapping result="root" exception="java.lang.Exception"></exception-mapping>
	     <exception-mapping result="sql" exception="java.sql.SQLException"></exception-mapping>
	  </global-exception-mappings>
	  <action name="loginException" class="com.dd.action.LoginExceptionAction">
	      <exception-mapping result="my" exception="com.dd.exception.MyException"></exception-mapping>
	      <result name="my">/exception.jsp</result>
	      <result name="error">/exception.jsp</result>
	      <result name="success">/exception.jsp</result>
	  </action>
	</package>
</struts>
