TypeError: Failed to execute ‘fetch‘ on ‘Window‘: Request with GET/HEAD method cannot have body.

swagger报错：

TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body.

原因：

使用了@ResponseBody，由于方法中申明的是get方法却用了@requestBody 

get无法使用获取参数。

解决：

将GetMapping 改为 PostMapping
