SpringMVC容器中Servlet如何調用service層接口

   直接最簡單有效的方法，重寫Servlet的Init()方法。代碼以下：

1)、 首先新建一個重寫Servlet的Init()方法的類繼承HttpServlet

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import org.springframework.beans.factory.config.AutowireCapableBeanFactory;

import org.springframework.web.context.WebApplicationContext;

import org.springframework.web.context.support.WebApplicationContextUtils;

/**

 * 描述：Servlet重寫Init()方法

 * @author WangKun

 */

public class ServletProxy extends HttpServlet {  

/**

*/

private static final long serialVersionUID = 1L;

public void init() throws ServletException {  

       super.init();  

       WebApplicationContext wac = WebApplicationContextUtils.getWebApplicationContext(getServletContext());  

       AutowireCapableBeanFactory factory = wac.getAutowireCapableBeanFactory();  

       factory.autowireBean(this);  

   }  

}  

2)、新建本身須要的Servlet再繼承重寫Servlet的類 (ServletProxy) 

import javax.servlet.ServletException;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
import org.springframework.beans.factory.annotation.Autowired;

public class ***Servlet extends ServletProxy {

@Autowired
private ***Service ***Service;

    private static final long serialVersionUID = 2827297299439162553L;  
  
    public void doGet(HttpServletRequest request, HttpServletResponse response)   throws Exception {  
        doPost(request, response);  

    }  
  
  
public void doPost(HttpServletRequest request, HttpServletResponse response)    throws Exception { 

         

          ***Service.本身的接口方法。

 

        你本身的東西本身寫了。     }    }
