第二十二弹，SpringBoot项目如何注入配置文件属性值

> 单个属性

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

/**
 * 图片路径配置
 *
 * @author wfeil211@foxmail.com
 * @version 1.0 2019-06-20  21:00:05
 */
@Configuration
public class ImageConfig {

    /** 图片根路径 */
    @Value("${image.root}")
    public String imageRoot;
}

image:
  root: url

> 同名类

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

/**
 * 初始化查询按钮
 *
 */
@Configuration
@ConfigurationProperties("bottonconfig")
public class BottonConfig {

    /** 按钮名字 */
    private String buttonName;

    /** 按钮标识 */
    private String buttonIdentity;

    public String getButtonName() {
        return buttonName;
    }

    public void setButtonName(String buttonName) {
        this.buttonName = buttonName;
    }

    public String getButtonIdentity() {
        return buttonIdentity;
    }

    public void setButtonIdentity(String buttonIdentity) {
        this.buttonIdentity = buttonIdentity;
    }
}

buttonconfig：
  buttonName: 查询
  buttonIdentity: search
