在servlet中注入spring环境

import java.io.IOException;  
  
import javax.servlet.ServletConfig;  
import javax.servlet.ServletException;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
  
import org.springframework.web.context.support.SpringBeanAutowiringSupport;  
  
/** 
 * Servlet implementation class AbstractServlet 
 */  
  
public class AbstractServlet extends HttpServlet {  
    private static final long serialVersionUID = 1L;  
  
    /** 
     * @see HttpServlet#HttpServlet() 
     */  
    public AbstractServlet() {  
        super();  
        // TODO Auto-generated constructor stub  
    }  
  
    public void init(ServletConfig config) throws ServletException {  
        SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this,  
                config.getServletContext());  
    }  
  
    /** 
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse 
     *      response) 
     */  
    protected void doGet(HttpServletRequest request,  
            HttpServletResponse response) throws ServletException, IOException {  
    }  
  
    /** 
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse 
     *      response) 
     */  
    protected void doPost(HttpServletRequest request,  
            HttpServletResponse response) throws ServletException, IOException {  
        doGet(request, response);  
    }  
  
}  

只需要集成这个servlet即可。
