Java 如何打印客户端'；在sprintmvc中遇到HttpMessageEndableException时，将原始post字符串发送到日志

当我向SpringMVC发布一个有效的JSON时，它工作得很好。但是如果json缺少一个引号或者其他方面无效。服务器将抛出一个名为

httpmessagegenoteradableexception

的异常，其中包含一些有用的信息，但它不会显示发送的JSON，这是测试人员需要知道的

例如，发布一个无效的JSON字符串：（在“code”属性后缺少引号）

服务器日志错误为：

Could not read document: Unexpected character ('#' (code 35)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
