springboot 增删改查全套流程

一、后端：Controller 完整版（4 个接口）

import com.ruoyi.common.core.controller.BaseController;
import com.ruoyi.common.core.domain.AjaxResult;
import com.ruoyi.common.core.page.TableDataInfo;
import com.ruoyi.common.log.annotation.Log;
import com.ruoyi.common.log.enums.BusinessType;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
import java.util.List;

@RestController
@RequestMapping("/system/user")
public class UserController extends BaseController {

    @Resource
    private UserService userService;

    // 1. 查询列表（分页）
    @GetMapping("/list")
    public TableDataInfo list(User user) {
        startPage();
        List<User> list = userService.selectUserList(user);
        return getDataTable(list);
    }

    // 2. 新增
    @Log(title = "用户管理", businessType = BusinessType.INSERT)
    @PostMapping
    public AjaxResult add(@RequestBody User user) {
        return AjaxResult.success(userService.insertUser(user));
    }

    // 3. 修改
    @Log(title = "用户管理", businessType = BusinessType.UPDATE)
    @PutMapping
    public AjaxResult edit(@RequestBody User user) {
        return AjaxResult.success(userService.updateUser(user));
    }

    // 4. 删除
    @Log(title = "用户管理", businessType = BusinessType.DELETE)
    @DeleteMapping("/{userId}")
    public AjaxResult remove(@PathVariable Long userId) {
        return AjaxResult.success(userService.deleteUserById(userId));
    }
}

二、前端：Vue3 API 完整版（4 个接口）

新建文件：user.js

import request from '@/utils/request'

// 1. 查询用户列表
export function listUser(query) {
  return request({
    url: '/system/user/list',
    method: 'get',
    params: query
  })
}

// 2. 新增用户
export function addUser(data) {
  return request({
    url: '/system/user',
    method: 'post',
    data: data
  })
}

// 3. 修改用户
export function updateUser(data) {
  return request({
    url: '/system/user',
    method: 'put',
    data: data
  })
}

// 4. 删除用户
export function delUser(userId) {
  return request({
    url: '/system/user/' + userId,
    method: 'delete'
  })
}
