超详细超实用！！！零基础java开发之云风笔记接口开发之查询单条笔记详细信息（十二）

一、service/NoteApi新增getNodeDetail接口定义

public interface NoteApi {
    ...
    NoteManage getNoteDetail(int id);
}

二、service/impl/NoteServiceImpl接口实现逻辑

public class NoteServiceImpl implements NoteApi {
    @Autowired
    NoteMapper noteMapper;
    ...

    public NoteManage getNoteDetail(int noteId) {
        return noteMapper.getNoteDetail(noteId);
    }

}

三、mapper/NoteMapper新增接口

...
public interface NoteMapper {
    ...
    NoteManage getNoteDetail(int noteId);
}

四、新增sql语句

<select id="getNoteDetail" resultMap="BaseResultMap">
    select * from `note` where id = #{id} limit 1
</select>

五、控制类NoteController新增更新逻辑

import org.springframework.web.bind.annotation.*;
...
@RequestMapping(value = "/getNoteDetail",method = RequestMethod.GET)
public Response getNoteDetail(@RequestParam("id") Integer id){
    Response response = new Response();
    NoteManage note = service.getNoteDetail(id);
    response.setResponse(true,"查询成功",200,note);
    return response;
}
