【springboot】加载.properties文件中的中文时，页面显示乱码“？”

package com.wyf.entity;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

@Component //把本配置放入到Spring容器中，使其被扫描到
@ConfigurationProperties(prefix = "user")
@PropertySource(value="classpath:MyConfig.properties", encoding = "utf-8")
public class MyConfig {
    public String username;
    public Integer age;
    public String sex;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}

全局配置文件中也加了编码方式encoding : utf-8
（由于我电脑在csdn上传图片老出现错误，所以在此文字描述解决方案）
最终发现是idea编码方式的配置问题
修改idea的编码配置方式：
File -> setting -> Editor -> File Encodings
Global Encoding: UTF-8
Project Encoding: UTF-8
Properties Files(*.properties)
Default encoding for properties files: UTF-8 勾上后面的方框
