今天在controller中获取post参数时，报了如下错误

  1. { 
  2.     "timestamp": "2018-09-07T07:25:51.524+0000", 
  3.     "status": 500, "error": "Internal Server Error", 
  4.     "message": "Optional int parameter 'id' is present but cannot be translated into a null value due to being declared as a primitive type. Consider declaring it as object wrapper for the corresponding primitive type.", 
  5.     "path": "/user/add" 
  6. }

查看报错信息

  1. Optional int parameter 'id' is present but cannot be translated into a null value

意思是id不能转换为空，后面也给出了修改的建议

  1. Consider declaring it as object wrapper for the corresponding primitive type.

可以用包装类Integer来避免这个错误

在springmvc接受参数的时候，尽量不要使用基本数据类型
