该错误是由于Spring框架与com.fasterxml.jackson.core库版本不匹配导致的。解决方案包括更新Spring框架版本或调整Jackson库版本以达到兼容性。例如，Spring 5.0.3.RELEASE对应Jackson 2.9.4，而Spring 4.1.7.RELEASE对应Jackson 2.5.4。确保这些版本匹配可以解决HTTP 500 Internal Server Error问题。

原因是com.fasterxml.jackson.core:xxxx jar包与项目Spring框架的版本不一致。
解决办法：
更改Spring框架版本，或者更改Jackson jar包版本，使其兼容即可解决
例如：
Spring版本：5.0.3.RELEASE 对应 jackson版本：2.9.4
或者
Spring版本：4.1.7.RELEASE 对应 jackson版本：2.5.4
