前端調用這個方法報錯：

 

 

HTTP Status 406 – Not Acceptable

---

Type Status Report

Description The target resource does not have a current representation that would be acceptable to the user agent, according to the proactive negotiation header fields received in the request, and the server is unwilling to supply a default representation.

方法使用了@ResponseBody來返回json，然后注解 produces="text/html;charset=UTF-8" 又說返回的是 text/html，互相矛盾，去掉注解  produces="text/html;charset=UTF-8"  就好了。
