SpringBoot整合Mybatis -- 配置文件版

1、项目资源结构目录

2、创建mybatis-config.xml

3、创建EmployeeMapper.xml

     
         select * from employee where id = #{id}
     

    
        insert into employee(lastName, email, gender, d_id) values(#{lastName}, #{email}, #{gender}, #{dId})
    

4、application.yml文件中配置，指定全局配置文件的位置

mybatis:
  config-location: classpath:mybatis/mybatis-config.xml
  mapper-locations: classpath:mybatis/mapper/*.xml

5、编写controller

  @ResponseBody
    @GetMapping("/emp/{id}")
    public Employee findEmpById(@PathVariable("id") Integer id){ //@PathVariable接收请求路径中占位符的值
        Employee employee = employeeMapper.queryById(id);
        return employee;
    }
