把注解替換為：↓@RequestMapping(value = '/hello',produces = {'application/json;charset=UTF-8'})

HelloController：

package com.keafmd.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;/** * Keafmd * * @ClassName: HelloController * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-04-02 9:42 * @Blog: https://keafmd.blog.csdn.net/ */@RestControllerpublic class HelloController { @RequestMapping(value = '/hello',produces = {'application/json;charset=UTF-8'}) //@RequestMapping('/hello') Map hello(){ Map map = new HashMap(); map.put('keafmd','牛哄哄的柯南'); map.put('success',true); return map; }}
