Unexpected character (‘ ‘ (code 160)): was expecting double-quote to start field name； nested except

postman报错：

    "timestamp": "2023-03-28T10:08:58.498+00:00",
    "status": 400,
    "error": "Bad Request",
    "path": "/user/save"
}

idea报错：

Unexpected character (' ' (code 160)): 
was expecting double-quote to start field name; 
nested exception is com.fasterxml.jackson.core.JsonParseException: 
Unexpected character (' ' (code 160)):

 line: 2, column: 3]]

 原因：postman这段json是我从微信复制过来的，格式不对，空格应该有隐形点点。可对比下图跟第一个图

解决：将空格删掉，自己在postman中换行，行成下图的点点

而且要注意行跟行不能有空格，冒号周围也不能有复制过来的空格。

看idea的报错，会提示你在第几列第几个字符有问题
