Java 獲取控制層中@GetMapping、@PostMapping、@RequestMapping的值

前言

需求：有一張表，數據如下。SRV_DESC字段值為查詢列表信息，需要修改為如圖示的描述信息。示例：查詢列表信息，修改后為單據狀態-查詢列表信息。

SRV_URL字段值為控制層中的@GetMapping、@PostMapping的值。示例 ：@GetMapping("/102020029")。根據此值修改SRV_DESC的值。

 由於數據量過大，所以搞成了頁面操作方式。直接傳參數類名、類路徑、需要追加的值即可。

下面直接上代碼：（代碼過於簡陋，還請大佬勿噴）

public Result findList(String param, String classNamePath, String className) throws ClassNotFoundException {
//        String classNamePath = "com.xxx.sys.controller.";
//        String className = "BtnController";
        Class<?> clazz = Class.forName(classNamePath + className);
        //得到字節碼文件  【只需要更改controller類名】
//        Class<?> clazz = BtnController.class;
        //得到方法
        Method[] methods = clazz.getDeclaredMethods();
        for (Method method : methods) {
            //判斷是否存在GetMapping注釋
            boolean present1 = method.isAnnotationPresent(GetMapping.class);
            if (present1) {
                //得到requestMapping注釋
                GetMapping annotation = method.getAnnotation(GetMapping.class);
                //輸出 annotation RequestMapping包含的信息(headers=[], name=, path=[], value=[toTicket], produces=[], method=[], params=[], consumes=[])
                //System.err.println(annotation);
                //得到value數組
                String[] value = annotation.value();
                for (String string2 : value) {
                    //輸出value值
                    System.out.println("Get: " + string2.replace("/",""));
                    SrvObj obj = new SrvObj();
                    obj.setSrvUrl(string2.replace("/",""));
//                    srvObjService.updateSrvObjDesc(param, obj);
                }
            }
            //判斷是否存在PostMapping注釋
            boolean present2 = method.isAnnotationPresent(PostMapping.class);
            if (present2) {
                //得到PostMapping注釋
                PostMapping annotation = method.getAnnotation(PostMapping.class);
                //得到value數組
                String[] value = annotation.value();
                for (String string2 : value) {
                    //輸出value值
                    System.out.println("Post: " + string2.replace("/",""));
                    SrvObj obj = new SrvObj();
                    obj.setSrvUrl(string2.replace("/",""));
//                    srvObjService.updateSrvObjDesc(param, obj);
                }
            }

        }
        return Result.success();
    }

public int updateSrvObjDesc(String param, SrvObj srvObj){
        QueryWrapper<SrvObj> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("SRV_URL", srvObj.getSrvUrl());
        SrvObj srvObj1 = srvObjMapper.selectOne(queryWrapper);
        int affectRows = 0;
        if(srvObj1 != null){
            srvObj.setSrvDesc(param + srvObj1.getSrvDesc());
            UpdateWrapper<SrvObj> updateWrapper=new UpdateWrapper<>();
            updateWrapper.eq("SRV_URL",srvObj.getSrvUrl());
            affectRows = srvObjMapper.update(srvObj, updateWrapper);
            if(affectRows>0){
                System.out.println("更新成功");
            }else{
                System.out.println("更新失敗");
            }
        }
        return affectRows;
    }
