JSONUtils.checkParams(params, userId, testCode, cropKind) 3、响应数据务必使用封装好的枚举类及对应的结果类
响应枚举类尽量放在controller层处理 4、修改数据配合前端失焦及延时保存传值应做到哪个发生变化修改哪个而不是每次全行修改 5、swagger注解务必添加并配备真实入参及描述信息 6、如使用RequestMapping注解需指定method类型 7、关键点增加日志记录及异常信息捕捉输出 8、service层方法入参应以具体的参数为主而非对象传参
所有的参数在controller层中接受成具体的属性之后传到service中 9、mybatis中sql关键字必须大写 10、删除无用引入包、无用变量、无用mapper方法
11、为了避免obj为null的现象应该这样写
查询 新增 修改删除这样写在setObj的时候把查询的列表数据放进去因为前端还要做列表刷新

这种需要处理成批量插入错误写法 正确示范

13.批量删除也要做成批量的
错误写法改成批量的 正确写法

14、无用的定义要去掉无用的定义浪费系统资源
