):注意 主要问题的全部 stack 信息可以在 server logs 里查看
@ResponseBody
今天在写使用vue+axios+ssm完成异步请求的时候，因为前端接收的是json对象，所以在controller中加上了@ResponseBody注解，因为这个注解要结合jackson依赖使用，便使用maven导入，由于本人是直接写了整合，jar包是一下全都导进去的，便导致了上面的报错，此报错的根本原因是springjar包与jackson包不兼容导致，在升级了jackson的版本之后，报错完美解决。
出现这个问题，可能有问题的地方有：
1.配置文件是否有误。
2.版本兼容问题
最后感谢这个老哥的博客：blog.csdn.net/an_xiaowu/a…
