基于springboot mybatis vue的项目实战之增删改查CRUD—Restful风格

2024-06-26 23:06:13 前端知识 前端哥 850 286 我要收藏

整个代码与前面的案例基于springboot+mybatis+vue的项目实战之增删改查CRUD-CSDN博客

mapper和servie没有任何的变化。

有变化的主要是controller和html页面

1、controller

package com.example.controller;

import com.example.pojo.Peot;
import com.example.pojo.Result;
import com.example.service.PeotService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
public class PeotRestfulController {

    @Autowired
    private PeotService peotService;


    //-------查询所有-------

    @GetMapping("/peots")
    public Result findAllJson1() {
        return Result.seccess(peotService.findAll());
    }


    //-------按id进行删除-------

    @DeleteMapping("/peots/{id}")
    public void deletePeot1(@PathVariable("id") Integer id) {
        peotService.deletePeot(id);
    }

    // -------按id进行查询-------

    @GetMapping("/peots/{id}")
    public Result peotfindById(@PathVariable("id") Integer id) {
        return Result.seccess(peotService.peotfindById(id));
    }

    //-----更新-------

    @PutMapping("/peots")
    public Result updatePeot(@RequestBody Peot peot) {
        boolean r = peotService.updatePeot(peot);

        if (r) {
            // 成功  code==1
            return Result.success();
        } else {
            // 失败  code==0
            return Result.erro("更新失败");
        }
    }

    //-------插入-------

    @PostMapping("/peots")
    public Result insertUser(@RequestBody Peot peot) {
        boolean result = peotService.insertUser(peot);
        if (result) {
            // 成功  code==1
            return Result.success();
        } else {
            // 失败  code==0
            return Result.erro("添加失败");

        }

    }

}

2、html页面

peot_listAll_restful.html

      <th>操作</th>
    </tr>
    <tr v-for="peot in peotList">

        <a :href="'peot_delete2.html?id='+peot.id">删除</a>

      </td>
    </tr>

  </table>
</div>

</body>

<script>
  new Vue({

    },

        var _this = this;

    },

      // 通过id查询详情
      this.findAll();
    },
  })
