4 . 修改web,xml


     
         
      
       mybatis
          
              
       
        contextConfigLocation
               
       
        classpath:spring-*.xml
           
          
              
       
        字符集过滤器
               
       
        encodingFilter
               
       
        org.springframework.web.filter.CharacterEncodingFilter
               
                   
        
         字符集编码
                    
        
         encoding

        encodingFilter
               
       
        /*
           
          
              
       
        spring监听器
               
       
        org.springframework.web.context.ContextLoaderListener
           
          
              
       
        org.springframework.web.util.IntrospectorCleanupListener
           
          
              
       
        spring mvc servlet
               
       
        springMvc
               
       
        org.springframework.web.servlet.DispatcherServlet
               
                   
        
         spring mvc 配置文件
                    
        
         contextConfigLocation
                    
        
         classpath:spring-mvc.xml
                
               
       
        1
           
          
              
       
        springMvc
               
       
        *.do
           
          
              
       
        /index.jsp
           
          
              
       
        15

5. controller 如下

1 package com.sd.test.controller; 2  3 import java.io.IOException; 4  5 import javax.annotation.Resource; 6 import javax.servlet.http.HttpServletRequest; 7 import javax.servlet.http.HttpServletResponse; 8  9 import org.springframework.stereotype.Controller;10 import org.springframework.web.bind.annotation.RequestMapping;11 12 import com.sd.test.model.TTest;13 import com.sd.test.service.TestService;14 15 @Controller16 @RequestMapping("/test")17 public class TestController {18     @Resource19     private TestService testService;20 21     @RequestMapping("selectOne")22     public void findById(HttpServletRequest request,23             HttpServletResponse response) throws IOException {24         String id = request.getParameter("id");25         Object obj = this.testService.selectOne(Integer.parseInt(id));26         response.getWriter().print(obj);27     }28 29     @RequestMapping("save")30     public void save(HttpServletRequest request, HttpServletResponse response) {31         String name = request.getParameter("name");32         TTest t = new TTest();33         t.setUsername(name);34         this.testService.save(t);35 36     }37 38     @RequestMapping("tsave")39     public void tsave(HttpServletRequest request, HttpServletResponse response) {40         String name = request.getParameter("name");41         TTest t = new TTest();42         t.setUsername(name);43         int i = (Integer) this.testService.put(t);44         System.out.println(i);45     }46 47 }

serviceImpl 如下:

package com.sd.test.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.sd.test.dao.TTestMapper;import com.sd.test.model.TTest;import com.sd.test.service.TestService;@Servicepublic class TestServiceImpl implements TestService {    // @Resource    // private TTestMapper mapper;    @Override    public void save(Object obj) {        // int i = this.mapper.insert((TTest) obj);        // System.out.println("save = " + i);        System.out.println("save");    }    @Override    public Object selectOne(Object obj) {        System.out.println("selectOne");        TTest tt = null;        // TTest tt = this.mapper.selectByPrimaryKey(Integer.parseInt(obj        // .toString()));        return tt;    }    @Override    public Object put(Object obj) {        System.out.println("put");        // return this.mapper.insert((TTest) obj);        return null;    }}
