“JSON parse error: Unexpected character (‘\“‘ (code 34)): was expecting comma to separate Object ent

JsonEOFException

json报错一般都是格式问题，首先检查参数格式

报错"JSON parse error: Unexpected character ('\"' (code 34)): was expecting comma to separate Object entries; nested exception is com.fasterxml.jackson.core.JsonParseExc

只需要看这个'\"'，代表换行符报错，缺少换行分隔符的含义

JSON parse error: Unexpected end-of-input: expected close marker for Object (start marker at [Source: (PushbackInputStream);

JSON parse error: Unexpected character ('}' (code 125)): was expecting double-quote to start field name; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('}' (code 125)): was expecting double-quote to start field name

缺少集合，就是缺少{}

JSON parse error: Unexpected character (’”’ (code 34))

缺少"

最后看到下面这一堆报错不要慌，只需要看第一行('\"' (code 34)这个报错就可以，分析具体是什么问题导致
