关于spring mvc json请求 415问题

最近在搭post json请求的spring mvc 框架，

吸收教训

开发过程中的注意事项：

（1）调用接口Header中不添加Content-Type为application/json 

（2）在编写SpringMVC的配置文件的时候忘记添加  <mvc:annotation-driven /> 

（3）忘记导入jackson的jar包

代码大致是这样子写的，感觉一点问题都没有，但是报415，如果用get请求就没问题。

@RequestMapping(value="/insertUser",method=RequestMethod.POST,consumes = "application/json") public @ResponseBody ComResponse insertUser(@RequestBody InsertUserRequest request){}

报错内容如下：
