spring+struts2.0整合-优快云博客

本文介绍了如何在项目中配置Spring与Struts框架的整合，包括web.xml的配置细节、Struts.xml的设置以及错误页面的统一管理。通过具体示例展示了如何加载Spring配置文件、配置监听器和过滤器，并在Struts中定义全局结果和异常映射。

spring配置文件都放到src/conf/spring目录中，struts.xml放在src目录下
1、web.xml配置如下


<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>b2b.root</param-value>
  </context-param>
  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/log4j.properties</param-value>
  </context-param>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:conf/spring/spring*.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <filter>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    <init-param>
      <param-name>singleSession</param-name>
      <param-value>false</param-value> <!--设置成false，才能保证在jsp页面调用Bean中的lazy对象时不会出错-->
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

修改struts.xml，


<?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>

<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<constant name="struts.devMode" value="true"/>
<constant name="struts.i18n.encoding" value="UTF8"/>

   <package name="default" namespace="/" extends="struts-default">
           <global-results>
       			<result name="businessError">/pages/errors/BusinessErrorPage.jsp</result>
       			<result name="dbError">/pages/errors/DBErrorPage.jsp</result>
       			<result name="httpError">/pages/errors/HTTPErrorPage.jsp</result>
       			<result name="permissionError">/pages/errors/PermissionErrorPage.jsp</result>
       		 <!-- 当Session失效时，统一转到这个页面 -->
		    		<result name="login" type="redirectAction">Login_input</result>
		    		<result name="json" type="json"></result>
          	<result name="error">/pages/bp/errorPage.jsp</result>
       	</global-results>

	      <global-exception-mappings>
       		<exception-mapping result="businessError" exception="XXXException"></exception-mapping>
       		<exception-mapping result="httpError" exception="XXXXException"></exception-mapping>
       	</global-exception-mappings>

    </package>
     <include file="struts_*.xml"/>
</struts>
