这个报错通常是因为JSON数据格式不正确导致的。请检查你的JSON数据是否有语法错误,比如单引号和双引号使用混淆,或者缺少逗号等。你可以使用在线的JSON格式验证工具来检查JSON是否正确。另外,如果你使用的是某个框架或库对JSON数据进行解析,也有可能是这些工具的问题导致的错误。你可以查看相关的文档或者在社区中寻求帮助。

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unexpected character ('}' (code 125)):
org.springframework.http.converter.HttpMessageNotReadableException是一个Spring框架中的异常类。它通常在处理HTTP请求时出现,表明在解析JSON数据时发生了错误。
具体地说,在这个问题中,异常消息中提到了一个JSON解析错误,即"Unexpected character ('}' (code 125)): was expecting double-quote to start field name"。这个错误意味着在JSON数据中遇到了一个不期望的字符("}"),而解析器期望的是一个双引号来开启字段名。
这种情况通常发生在JSON数据不符合正确的格式要求时。可能的原因包括,JSON数据中缺少双引号、字段名和值之间缺少冒号、非法的转义字符等等。要解决这个问题,您可以检查您的JSON数据,确保它符合JSON的语法规范。
此外,在提供的引用中还提到了一个相关的解决方法。它建议使用Node.js中的destr库来更快、更安全、更方便地替代JSON解析。您可以使用npm或yarn来安装该库,并将其导入到您的Node.js项目中。
因此,要解决这个问题,您可以检查您的JSON数据是否符合语法规范,并考虑使用destr库来进行JSON解析。

Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unexpected character (',' (code 44)):
This error occurs when the JSON received by the server is not in a valid format. The server is unable to parse the JSON due to the presence of an unexpected character (',' in this case).
To resolve this issue, you can try the following steps:
1. Check the JSON data being sent to the server and ensure that it is in a valid format. You can use a JSON validator tool to validate the JSON.
2. If the JSON data is being sent from the client application, ensure that the JSON serializer is properly configured to generate valid JSON.
3. Check the server-side code that is parsing the JSON and ensure that it is properly configured to handle the JSON data.
4. Check the HTTP headers being sent with the request and ensure that they are properly configured to indicate that JSON data is being sent.
5. If the issue persists, you can try to capture the network traffic using a tool like Wireshark to identify any issues with the data being sent over the network.
