SpringBoot:默认情况下NotReadableException被Resolver拦截,但是不打印错误堆栈,应如何处理?

Question

最近在做一个小Demo, 但是发现一个问题,当前端请求的时候,后端出现异常:

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of java.lang.Long out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.lang.Long out of START_OBJECT token at [Source: (PushbackInputStream); line: 1, column: 1]

问题在于后台没有打印错误堆栈, 而是使用一个Resolver拦截了, 并且级别是WARN, 打印如下:

WARN o.s.w.s.m.m.a.ExceptionHandlerExceptionResolver - Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of java.lang.Long out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.lang.Long out of START_OBJECT token at [Source: (PushbackInputStream); line: 1, column: 1]]

为什么会有这样的拦截, 不应该直接报错吗? 大神指点, 多谢
