Struts1.2中多config的实现_struts configuration 1.2-优快云博客

本文详细介绍了如何在Struts框架中创建自定义请求处理器，包括处理创建Action、填充form、预处理请求的功能，并通过配置web.xml和struts-config.xml文件实现与框架的集成。此外，文章还展示了如何在index.jsp页面使用此处理器。

在com.shiryu中新建MyRequestProcesser.java

package com.shiryu;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.RequestProcessor;

public class MyRequestProcesser extends RequestProcessor {

    @Override
    protected Action processActionCreate(HttpServletRequest request,
            HttpServletResponse response, ActionMapping mapping)
            throws IOException {
        // TODO Auto-generated method stub
        System.out.print("-----------创建Action-----------");
        return super.processActionCreate(request, response, mapping);
    }

    @Override
    protected ActionForm processActionForm(HttpServletRequest request,
            HttpServletResponse response, ActionMapping mapping) {
        // TODO Auto-generated method stub
        System.out.print("-----------填充form-----------");
        return super.processActionForm(request, response, mapping);
    }

    @Override
    protected boolean processPreprocess(HttpServletRequest request,
            HttpServletResponse response) {
        // TODO Auto-generated method stub
        System.out.print("-----------预处理请求-----------");
        String address = request.getRemoteAddr();
        int position = address.lastIndexOf(".");
        String last = address.substring(position + 1);
        int lastNum = Integer.parseInt(last);

        if (address.substring(0, 9).equals("125.221.33")
                && (lastNum <= 151 && lastNum > 0)) {
            System.out.print(address+lastNum);
            return true;
        }
        if(address.equals("127.0.0.1")){
            System.out.print(address+lastNum);
            return true;
        }else {
            return false;
        }
    }
}

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

在web-inf 新建并配置 struts-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards />
<action-mappings>
    <action
           path="/test"
           type="org.apache.struts.actions.SwitchAction">
    </action>
</action-mappings>
<message-resources parameter="com.shiryu.ApplicationResources" />

<controller processorClass="com.shiryu.MyRequestProcesser"></controller>
</struts-config>

配置struts-config1.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards />
<action-mappings>
   <action path="/wel" forward="/wel.jsp"></action>
</action-mappings>
<message-resources parameter="com.shiryu.ApplicationResources" />
</struts-config>

新建index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>

<body>
    This is my JSP page. <br>
    <a href="test.do?prefix=/shiryu&page=/wel.do">zhaiyu</a>
