一、日志和容错注解必不可少。

public static Logger log=LoggerFactory.getLogger(LrmLawyerAbroadController.class);
    
        @Autowired
        private LrmLawyerAbroadService lrmLawyerAbroadService;

二、查看。

/**
         * 查看律师信息
         */
        @RequestMapping(value = "/queryProjectBaseInfoList", method = RequestMethod.POST)//发送post请求，设置请求路径
        public ResultInfoDTO<PageInfo<LrmLawyerAbroad>> queryProjectBaseInfoList() {
            Map<String, Object> queryParams = this.getParams(getRequest());
            ResultInfoDTO<PageInfo<LrmLawyerAbroad>> resultInfoDTO = new ResultInfoDTO<>();
            try {
                log.info("查看律师列表开始 --------->queryParams:" + queryParams);
                PageInfo<LrmLawyerAbroad> pageInfo = lrmLawyerAbroadService.queryProjectBaseInfoList(queryParams);
                resultInfoDTO.setData(pageInfo);
                resultInfoDTO.setReturnValue(true);
                resultInfoDTO.setMsg("查询成功");
                log.info("查看律师列表结束 --------->");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("查看律师列表异常");
                throw new BussinessException(Constant.FAIL, "查看律师列表异常");
            }
            return resultInfoDTO;
        }

三、新增。

/**
         * 新增律师信息
         * @param lrmLawyerAbroad
         * @return
         */
        @RequestMapping(value = "/insertLawyerAbroadInfo", method = RequestMethod.POST)
        public ResultInfoDTO<Integer> insertLawyerAbroadInfo(@RequestBody LrmLawyerAbroad lrmLawyerAbroad) {
            ResultInfoDTO<Integer> resultInfoDTO = new ResultInfoDTO<>();
            try {
                log.info("新增律师信息开始 --------->");
                int flag = lrmLawyerAbroadService.insertLawyerAbroadInfo(lrmLawyerAbroad);
                resultInfoDTO.setData(flag);
                resultInfoDTO.setReturnValue(true);
                resultInfoDTO.setMsg("新增律师信息成功");
                log.info("新增律师信息结束 --------->");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("新增律师信息异常");
                throw new BussinessException(Constant.FAIL, "新增律师信息异常");
            }
    
            return resultInfoDTO;
        }

四、删除。

/**
         * 删除律师信息
         * @param lawyerInfoId
         * @return
         */
        @RequestMapping(value = "/removeLawyerAbroad", method = RequestMethod.POST)
        public ResultInfoDTO<Integer> removeLawyerAbroad(String lawyerInfoId) {
            ResultInfoDTO<Integer> infoDTO = new ResultInfoDTO<>();
            try {
                log.info("删除律师信息开始 --------->");
                int flag = lrmLawyerAbroadService.removeLawyerAbroad(lawyerInfoId);
                infoDTO.setData(flag);
                infoDTO.setReturnValue(true);
                infoDTO.setMsg("删除律师信息成功");
                log.info("删除律师信息结束 --------->");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("删除律师信息异常");
                throw new BussinessException(Constant.FAIL, "删除律师信息异常");
            }
    
            return infoDTO;
        }

五、获取编辑前信息。

/**
         * 编辑前获取律师信息
         * @param lawyerInfoId
         * @return
         */
        @RequestMapping(value = "/querylawyerAbroadById", method = RequestMethod.POST)
        public ResultInfoDTO<LrmLawyerAbroad> querylawyerAbroadById(String lawyerInfoId) {
            ResultInfoDTO<LrmLawyerAbroad> infoDTO = new ResultInfoDTO<>();
            try {
                log.info("编辑前获取律师信息开始 --------->");
                LrmLawyerAbroad lrmLawyerAbroad = lrmLawyerAbroadService.selectByPrimaryKey(lawyerInfoId);
                infoDTO.setData(lrmLawyerAbroad);
                infoDTO.setReturnValue(true);
                infoDTO.setMsg("编辑前获取律师信息成功");
    
                log.info("编辑前获取律师信息结束 --------->");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("编辑前获取律师信息异常");
                throw new BussinessException(Constant.FAIL, "编辑前获取律师信息异常");
            }
    
            return infoDTO;
        }

六、编辑更新。

/**
         * 编辑更新律师信息
         * @param lrmLawyerAbroad
         * @return
         */
        @RequestMapping(value = "/updateByPrimaryKeySelective", method = RequestMethod.POST)
        public ResultInfoDTO<Integer> updateByPrimaryKeySelective(@RequestBody LrmLawyerAbroad lrmLawyerAbroad) {
            ResultInfoDTO<Integer> infoDTO = new ResultInfoDTO<>();
            try {
                log.info("编辑律师信息开始 --------->");
                int flag = lrmLawyerAbroadService.updateByPrimaryKeySelective(lrmLawyerAbroad);
                infoDTO.setData(flag);
                infoDTO.setReturnValue(true);
                infoDTO.setMsg("编辑律师信息成功");
    
                log.info("编辑律师信息结束 --------->");
            } catch (Exception e) {
                e.printStackTrace();
                log.error("编辑律师信息异常");
                throw new BussinessException(Constant.FAIL, "编辑律师信息异常");
            }
    
            return infoDTO;
        }

写的时候切记，方法名称要前后对应。
