今天在controller中获取post参数时,报了如下错误
{
"timestamp": "2018-09-07T07:25:51.524+0000",
"status": 500, "error": "Internal Server Error",
"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.",
"path": "/user/add"
}
查看报错信息
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
Consider declaring it as object wrapper for the corresponding primitive type.
可以用包装类来避免这个错误
在springmvc接受参数的时候,尽量不要使用基本数据类型
