   三、配置文件

 

    web,xml文件

 

    
    
        useChinese
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            utf-8
        
    
    
        useChinese
        *.do
    
    
        contextConfigLocation
        classpath:config/mybatis.xml
    
    
        org.springframework.web.context.ContextLoaderListener
                                                                       
    
    
        SpringMVC
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation

   mvc.xml

   mybatis.xml

  四、定义数据库操作

 

   实体Test.class

 

package main.dao.entity;

/**
 * Created by swordbone on 2017/11/29.
 */
public class Test {
    private Integer id;
    private String name;
    private Integer age;
    private String nickname;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getNickname() {
        return nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    @Override
    public String toString() {
        return "Test{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", nickName='" + nickname + '\'' +
                '}';
    }
}

 

 

    testMapper.xml文件

 

    
        
        
        
        
    
    
        SELECT * FROM test WHERE 1=1
        
            AND ID=#{id,jdbcType=INTEGER}
        
        
            AND ID=#{name,jdbcType=VARCHAR}
        
    
    
        INSERT INTO test
        
            
                ID,
            
            
                NAME,
            
            
                AGE,
            
            
                NICKNAME
            
        
        
            
                #{id,jdbcType=INTEGER},
            
            
                #{name,jdbcType=VARCHAR},
            
            
                #{age,jdbcType=INTEGER},
            
            
                #{nickname,jdbcType=VARCHAR}
            
        
    
    
        UPDATE test
        
            
                NAME=#{name},
            
            
                AGE=#{age,jdbcType=INTEGER},
            
            
                NICKNAME=#{nickname},
            
        
        WHERE ID=#{id}
    
    
        DELETE FROM test WHERE
        
            ID=#{id,jdbcType=INTEGER}
        
    

  在同一目录下创建dao接口，注意接口中的方法名与map.xml文件中的sql语句id相同，参数返回值都要对应

 

   TestMapper.class

 

package main.dao.idao;

import main.dao.entity.Test;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */
@Repository
public interface TestMapper {
    Integer createTest(Test test);
    List queryTest(Test test);
    Integer updateTest(Test test);
    Integer deleteTest(Integer id);
}

  五、service层

 

    service接口：TestService.class

 

package main.service.iService;

import main.dao.entity.Test;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */

public interface TestService {
    Integer createTest(Test test);
    List queryTest(Test test);
    Integer updateTest(Test test);
    Integer deleteTest(Integer id);
}

   service实现类：TestServiceImpl.class

package main.service.serviceImpl;

import main.dao.entity.Test;
import main.dao.idao.TestMapper;
import main.service.iService.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */
@Repository
public class TestServiceImpl implements TestService {
//自动装载dao接口
    @Autowired
    private TestMapper testMapper;
    public Integer createTest(Test test) {
        return testMapper.createTest(test);
    }

    public List queryTest(Test test) {
        return testMapper.queryTest(test);
    }

    public Integer updateTest(Test test) {
        return testMapper.updateTest(test);
    }

    public Integer deleteTest(Integer id) {
        return testMapper.deleteTest(id);
    }
}

 六、jsp页面

 

  新建test页面：create.jsp

  页面入口index.jsp

 

 

create
query 

 

 

 

七、controller

  TestController.class

 

package main.controller.test;

import main.dao.entity.Test;
import main.service.iService.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */
@Controller
@RequestMapping("/test")
public class TestController {
//   自动装载TestService接口
    @Autowired
    TestService testService;
//  查询所有的test
    @RequestMapping("/query")
    public String queryTest(ModelMap map, HttpServletRequest request, Test test){
        List list = testService.queryTest(test);
        map.addAttribute("list",list);
        return null;
    }
//    新建test
    @RequestMapping("/create")
    public String createTest(ModelMap map,HttpServletRequest request,Test test){
        Integer returnnum = testService.createTest(test);
        map.addAttribute("returnnum",returnnum);
        return "redirect:/test/query.do";
    }
//    编辑test
    @RequestMapping("/{id}/update")
    public String updateTest (ModelMap map, HttpServletRequest request, 
                                                     Test test, @PathVariable String id){
        Integer intId = Integer.valueOf(id);
        Test test1 = new Test();
        test1.setId(intId);
        List list = testService.queryTest(test1);
        map.addAttribute("test",list.get(0));
        return "/test/updatepage";
    }
//    更改test
    @RequestMapping("/updateForm")
    public String updateForm(ModelMap map,HttpServletRequest request,Test test){
        Integer returnint = testService.updateTest(test);
        return "redirect:/test/query.do";
    }
//    删除test
    @RequestMapping("/{id}/delete")
    public String deleteTest(ModelMap map,HttpServletRequest request,
                                                    Test test,@PathVariable String id){
        Integer intId = Integer.valueOf(id);
        Integer returnnum = testService.deleteTest(intId);
        map.addAttribute("returnnum",returnnum);
        return "redirect:/test/query.do";
    }
}

 项目页面：

 

   index.jsp

   点击query跳转到query.do

 点击create跳转到create.jsp

  新建一条数据
