</project>

6. 创建配置文件

resources目录下创建application.yml。

# 配置端口号
server:
  port: 8090

7. 创建Student实体类

com.wfit.boot.model目录下创建Student.java。

@Data
public class Student {
    //主键id
    private String id;
    //姓名
    private String name;
    //年龄
    private int age;
}

8. 创建StudentController类

com.wfit.boot.controller目录下创建StudentController.java。

@RestController
@RequestMapping("/student")
public class StudentController {

    @Autowired
    StudentService studentService;
    /**
     * 新增学生信息
     */
    @PostMapping("/add")
    public String add(@RequestBody Student student){
        studentService.addStudent(student);
        return "success";
    }
}

9. 创建StudentService接口

com.wfit.boot.service目录下创建StudentService.java。

public interface StudentService {
    public int addStudent(Student student);
}

10. 创建StudentServiceImpl类

com.wfit.boot.service.impl目录下创建StudentServiceImpl.java。

@Service
public class StudentServiceImpl implements StudentService {
    
    @Autowired
    private StudentDao studentDao;
    
    @Override
    public void addStudent(Student student) {
        studentDao.save(student);
    }
}

11. 创建StudentDao类

com.wfit.boot.dao目录下创建StudentDao.java。

@Repository
public class StudentDao {
    
    public void save(Student student){
        System.out.println("新增学生信息成功：" + student);
    }
    
}
