</configuration>

1.8 配置数据库

创建数据库，数据表student
表字段如下：

1.9 配置文件位置

2 编写后端代码

2.1 编写实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Student {private Integer sid;private String sname;private Integer sage;
}

2.2 编写Dao接口

@Mapper
public interface StudentDao {//查询所有List<Student> findAll();//新增数据int addStu(@Param("student") Student student);//删除数据int delStuById(Integer sid);//修改数据int updateStu(Student student);
}

2.3 编写Dao映射文件(resource目录下)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hx.dao.StudentDao"><!--查询所有列表--><select id="findAll" resultType="Student">select sid, sname, sagefrom student;</select><!--新增数据--><insert id="addStu">insert into studentvalues (#{student.sid}, #{student.sname}, #{student.sage});</insert><!--删除数据--><delete id="delStuById">deletefrom studentwhere sid = #{sid}</delete><!--修改数据--><update id="updateStu" parameterType="Student">update studentset sname=#{sname},sage=#{sage}where sid = #{sid}</update>
</mapper>

2.4 编写Service接口

public interface StudentService {//查询所有List<Student> selectAll();//插入数据int insertStu(Student student);int delStuById(Integer sid);int updateStu(Student student);
}

2.5 编写ServiceImpl实现类

@Service
public class StudentServiceImpl implements StudentService {@Autowiredprivate StudentDao studentDao;@Overridepublic List<Student> selectAll() {return studentDao.findAll();}@Overridepublic int insertStu(Student student) {return studentDao.addStu(student);}@Overridepublic int delStuById(Integer sid) {return studentDao.delStuById(sid);}@Overridepublic int updateStu(Student student) {return studentDao.updateStu(student);}
}

2.6 编写Controller类

1、业务Controller

@Controller
@RequestMapping("/student")
public class StudentController {@Autowiredprivate StudentService studentService;@GetMapping("/getAll.do")public ModelAndView getAll() {List<Student> list = studentService.selectAll();ModelAndView mv = new ModelAndView();mv.addObject("list", list);mv.setViewName("listStu");return mv;}@PostMapping("/add.do")public ModelAndView saveStu(Student student) {String tips = "插入失败";ModelAndView mv = new ModelAndView();int i = studentService.insertStu(student);if (i > 0) {tips = "插入成功";}mv.addObject("data1", tips);mv.setViewName("success");return mv;}@RequestMapping("/put.do")public ModelAndView putStu(Student student) {String tips = "修改失败！";ModelAndView mv = new ModelAndView();int i = studentService.updateStu(student);if (i > 0) {tips = "修改成功";}mv.addObject("data2", tips);mv.setViewName("success");return mv;}@RequestMapping(value = "/del.do")public ModelAndView delStu(Integer sid) {String tips = "删除失败！";ModelAndView mv = new ModelAndView();int i = studentService.delStuById(sid);if (i > 0) {tips = "删除成功";}mv.addObject("data3", tips);mv.setViewName("success");return mv;}
}

2、页面相关Controller

@RestController
@RequestMapping("/index")
public class IndexController {@RequestMapping("/m1Add.do")public ModelAndView m1Add(){ModelAndView mv = new ModelAndView();mv.setViewName("add");return mv;}@RequestMapping("/m2Put.do")public ModelAndView m2Put(){ModelAndView mv = new ModelAndView();mv.setViewName("put");return mv;}@RequestMapping("/m3Del.do")public ModelAndView m3Del(){ModelAndView mv = new ModelAndView();mv.setViewName("del");return mv;}
}

</head>
<body>
<div><h1>功能区首页</h1><br><button><a href="/student/getAll.do">查询数据</a></button><button><a href="/index/m1Add.do">插入数据</a></button><br><button><a href="/index/m2Put.do">修改数据</a></button><button><a href="/index/m3Del.do">删除数据</a></button>
