java - org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver resolveException

问题描述

我是java mvc的新手，我遇到了同样的错误

2020 年 1 月 27 日晚上 10:48:16 org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver resolveException 警告：已解决 [org.springframework.web.HttpMediaTypeNotSupportedException：不支持内容类型“应用程序/json”]

我附上了我的文件夹结构和代码。你能帮我做进一步的
文件夹结构吗

package com.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.bean.RegistrationBean;

@Controller
@RequestMapping("/helloworld")
public class InitController {

    @RequestMapping(value="/register.do",method = RequestMethod.POST)
    public String hello(@RequestBody RegistrationBean register,HttpServletRequest request) {
        
        System.out.println("controller test");
        return "asd";
    }

}
