返回json文件给前端

controller

    @ApiOperation("获取权限列表")
    @GetMapping("getAuthsList")
    public Result getAuthsList() {
     	//路径从resources开始
        JSONArray authsJsonData = authorizationService.getAuthsJsonData("**.json");
        return getRightResult(authsJsonData, new Integer(200));
    }

service

import com.yestar.common.utils.JsonResourceUtil;
 /**
   * 读取auths.json文件，获取所有权限内容
   * @param fileName
   * @return
   */
  @Override
  public JSONArray getAuthsJsonData(String fileName) {
      JSONArray jsonObjFromResource = JsonResourceUtil.getJsonObjFromResource(fileName);
      return jsonObjFromResource;
  }
