一、审核功能实现的方式

1、普通

方案：经办时入A表，审核后从A表读取数据，然后操作目标B表；

优势：思路简单

劣势：对后端功能实行高度的嵌入；审核功能数据操作不统一

2、弹框式

方案：前台实现，操作时判断是否需要权限控制，如果需要，则弹出框，由审核人员进行审核，审核通过后，进行后续操作。

优势：对后台功能无嵌入；可支持查询、导出、操作等全部功能；

劣势：需要经办人和审核人同时在场操作

3、入参缓冲时

方案：审核功能是独立的功能，前台发起业务后，入参存入数据库。待审核通过后，后台触发调用相应的接口，并将执行结果通知到经办人。

优势：对前后台功能均无嵌入；支持导出及操作类；经办人和审核人可以异步操作；审核功能数据操作统一；

劣势：需要框架层支持；实现逻辑稍微复杂

4、临时表

方案：所有需要审核功能涉及的表均增加相应的表，该表比源表主要增加1个字段，即审核流水，其余字段命名完全一致；所有功能操作时先入该表，审核通过后，由后台从该表将数据同步至正表。

优势：无需要框架支持；支持导出及操作类；经办人和审核人可以异步操作；审核功能数据操作统一；

劣势：对后端功能实行高度的嵌入；

二、SpringBoot实现

1.创建数据库表SQL


CREATE TABLE `audit` (
  `id` int NOT NULL AUTO_INCREMENT COMMENT 'ID',
  `name` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '报修名称',
  `user` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '报修人',
  `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '报修时间',
  `img` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '详情图片',
  `state` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT '待审核' COMMENT '待审核，审核通过，审核不通过',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

2.写Java后端

其实审核功能最主要的就是我们的新增功能，用户只有新增过后，我们的管理员才能去对你的申请进行审核，最后实现效果。

AuditController


import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.example.demo.common.Result;
import com.example.demo.entity.Audit;
import com.example.demo.entity.Sanitation;
import com.example.demo.entity.User;
import com.example.demo.mapper.FileMapper;
import com.example.demo.service.IAuditService;
import com.example.demo.utils.TokenUtils;
import org.springframework.web.bind.annotation.*;
 
import javax.annotation.Resource;
import java.util.List;
 
@CrossOrigin
@RestController
@RequestMapping("/audit")
public class AuditController {
 
    @Resource
    private IAuditService auditService;
 
    @Resource
    private FileMapper fileMapper;
 
//    //新增或者更新
//    @PostMapping
//    public Result save(@RequestBody Audit audit) {
//        audit.setUser(TokenUtils.getCurrentUser().getUsername());
        audit.setImg(Files.url);
//        return Result.success(auditService.saveOrUpdate(audit));
//    }
 
    // 新增或者更新
    @PostMapping
    public Result save(@RequestBody Audit audit) {
        if (audit.getId() == null) {
            // 新增
            audit.setUser(TokenUtils.getCurrentUser().getUsername());
 
        }
        auditService.saveOrUpdate(audit);
        return Result.success();
    }
 
    //删除
//    @DeleteMapping("/{id}")
//    public Result delete(@PathVariable Integer id) {
//        return Result.success(userService.removeById(id));
//    }
 
    @PostMapping("/del/batch")
    public Result deleteBatch(@RequestBody List<Integer> ids) {//批量删除
        return Result.success(auditService.removeByIds(ids));
    }
 
    //查询所有数据
    @GetMapping
    public Result findAll() {
        return Result.success(auditService.list());
    }
 
//    @GetMapping("/role/{role}")
//    public Result findNames(@PathVariable String role) {
//        QueryWrapper<Audit> queryWrapper = new QueryWrapper<>();
//        queryWrapper.eq("role", role);
//        List<Audit> list = auditService.list(queryWrapper);
//        return Result.success(list);
//    }
 
    @GetMapping("/{id}")
    public Result findOne(@PathVariable Integer id) {
        return Result.success(auditService.getById(id));
    }
 
    @GetMapping("/username/{username}")
    public Result findByUsername(@PathVariable String username) {
        QueryWrapper<Audit> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("username", username);
        return Result.success(auditService.getOne(queryWrapper));
    }
 
    @GetMapping("/page")
    public Result findPage(@RequestParam Integer pageNum,
                           @RequestParam Integer pageSize,
                           @RequestParam(defaultValue = "") String name) {
        QueryWrapper<Audit> queryWrapper = new QueryWrapper<>();
        queryWrapper.orderByDesc("id");
        if (!"".equals(name)) {
            queryWrapper.like("name", name);
        }
        User currentUser = TokenUtils.getCurrentUser();
//        if (RoleEnum.ROLE_USER.toString().equals(currentUser.getRole())) {  // 角色是普通用户
//            queryWrapper.eq("user", currentUser.getUsername());
//        }
        return Result.success(auditService.page(new Page<>(pageNum, pageSize), queryWrapper));
 
    }
}

三、前端调用

1.实现效果

2.核心代码


<el-table-column label="审核" width="240">
  <template v-slot="scope">
    <el-button type="success" @click="changeState(scope.row, '审核通过...师傅正在赶来的路上')" :disabled="scope.row.state !== '待审核'">审核通过</el-button>
    <el-button type="danger" @click="changeState(scope.row, '审核不通过')" :disabled="scope.row.state !== '待审核'">审核不通过</el-button>
  </template>
</el-table-column>

3.后台管理

4.后台管理核心代码


import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.example.demo.common.Result;
import com.example.demo.entity.Audit;
import com.example.demo.entity.User;
import com.example.demo.mapper.FileMapper;
import com.example.demo.service.IAuditService;
import com.example.demo.utils.TokenUtils;
import org.springframework.web.bind.annotation.*;
 
import javax.annotation.Resource;
import java.util.List;
 
@CrossOrigin
@RestController
@RequestMapping("/audit")
public class AuditController {
 
    @Resource
    private IAuditService auditService;
 
    @Resource
    private FileMapper fileMapper;
 
//    //新增或者更新
//    @PostMapping
//    public Result save(@RequestBody Audit audit) {
//        audit.setUser(TokenUtils.getCurrentUser().getUsername());
        audit.setImg(Files.url);

//    }
 
    // 新增或者更新
    @PostMapping
    public Result save(@RequestBody Audit audit) {
        if (audit.getId() == null) {
            // 新增
            audit.setUser(TokenUtils.getCurrentUser().getUsername());
        }
        auditService.saveOrUpdate(audit);
        return Result.success();
    }
 
    //删除
//    @DeleteMapping("/{id}")
//    public Result delete(@PathVariable Integer id) {
//        return Result.success(userService.removeById(id));
//    }
 
    @PostMapping("/del/batch")

        return Result.success(auditService.removeByIds(ids));
    }
 
    //查询所有数据
    @GetMapping
    public Result findAll() {
        return Result.success(auditService.list());
    }
 
    @GetMapping("/{id}")
    public Result findOne(@PathVariable Integer id) {
        return Result.success(auditService.getById(id));
    }
 
    @GetMapping("/username/{username}")
    public Result findByUsername(@PathVariable String username) {
        QueryWrapper<Audit> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("username", username);
        return Result.success(auditService.getOne(queryWrapper));
    }
 
    @GetMapping("/page")
    public Result findPage(@RequestParam Integer pageNum,
                           @RequestParam Integer pageSize,
                           @RequestParam(defaultValue = "") String name) {
        QueryWrapper<Audit> queryWrapper = new QueryWrapper<>();
        queryWrapper.orderByDesc("id");
        if (!"".equals(name)) {
            queryWrapper.like("name", name);
        }
        User currentUser = TokenUtils.getCurrentUser();
//        if (RoleEnum.ROLE_USER.toString().equals(currentUser.getRole())) {  // 角色是普通用户
//            queryWrapper.eq("user", currentUser.getUsername());
//        }
        return Result.success(auditService.page(new Page<>(pageNum, pageSize), queryWrapper));
 
    }
}

5.vue前台完整代码

(1)、前台功能页面

前台负责新增请求,然后保存请求之后，我们管理员审核通过之后就不可以编辑和删除我们的请求，我们会保留数据在前台页面


<template>
