spring与servlet环境配置


		1、HttpServletProxy.java
 
[java]  
package com.zfy.commons.util;  
  
import java.io.IOException;  
  
import javax.servlet.ServletException;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
  
import org.springframework.web.context.WebApplicationContext;  
import org.springframework.web.context.support.WebApplicationContextUtils;  
  
public class HttpServletProxy extends HttpServlet {  
  
    private static final long serialVersionUID = 4382945551447764730L;  
  
    private String targetServlet;  
  
    private HttpServlet proxy;  
  
    public void destroy() {  
        super.destroy(); // Just puts "destroy" string in log   
        // Put your code here   
    }  
  
    public void init() throws ServletException {  
  
        this.targetServlet = getInitParameter("targetServlet");  
        getServletBean();  
        proxy.init(getServletConfig());  
    }  
  
    private void getServletBean() {  
        WebApplicationContext wac = WebApplicationContextUtils  
                .getRequiredWebApplicationContext(getServletContext());  
        this.proxy = (HttpServlet) wac.getBean(targetServlet);  
  
    }  
    @Override  
    public void service(HttpServletRequest request, HttpServletResponse response)  
            throws ServletException, IOException, RuntimeException {  
  
        proxy.service(request, response);  
    }  
}  
 
package com.zfy.commons.util;
 
import java.io.IOException;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
 
public class HttpServletProxy extends HttpServlet {
 
private static final long serialVersionUID = 4382945551447764730L;
 
private String targetServlet;
 
private HttpServlet proxy;
 
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
 
public void init() throws ServletException {
 
this.targetServlet = getInitParameter("targetServlet");
getServletBean();
proxy.init(getServletConfig());
}
 
private void getServletBean() {
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(getServletContext());
this.proxy = (HttpServlet) wac.getBean(targetServlet);
 
}
    @Override
public void service(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException, RuntimeException {
 
proxy.service(request, response);
}
}2、web.xml
