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；
Spring Boot 基础就不介绍了，推荐看这个实战项目：

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 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 queryWrapper = new QueryWrapper();// queryWrapper.eq("role", role);// List 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 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 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

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
