JSON parse error: Unexpected character (‘t‘ (code 116)): was expecting double-quote to start field n

POST发送JSON数据报错了：

JSON parse error: Unexpected character ('t' (code 116)): was expecting double-quote to start field name; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('t' (code 116)): was expecting double-quote to start field name\n at [Source: (org.springframework.util.StreamUtils$NonClosingInputStream); line: 2, column: 6]"

意思阐释：

SON分析错误:意外字符（“t”（代码116））:字段名称应该以双引号开头；嵌套异常为com . fasterxml . Jackson . core . jsonparseexception:意外字符（“t”（代码116））:应该在【Source:（org . spring framework . util . stream utils $ NonClosingInputStream】处以双引号开始字段名；第2行第6列】“

报错的原因：正确的书写格式是这样的，发送前后端都要加双引号：

{
    "title": "1",
    "content": "Hello World"
}
