Resolved [org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message;

回答: 引用\[1\]、\[2\]和\[3\]中提到的错误是SpringBoot请求接口报错的一种情况，具体是由于缺少相应的转换器导致的。错误信息中提到了"HttpMessageNotWritableException"和"JsonMappingException"，这意味着在处理请求时，SpringBoot无法将对象转换为JSON格式的响应。这可能是因为缺少适当的转换器或配置问题导致的。需要检查代码中是否正确配置了JSON转换器，并确保对象能够正确地序列化为JSON格式。另外，还需要检查是否存在权限相关的问题，如缺少权限或权限不正确导致的错误。
