使用@ConfigurationProperties封装配置文件
业务场景：
把配置文件的信息，读取并自动封装成实体类，可以使用@ConfigurationProperties，把同类的配置信息自动封装成实体类。
1、在pom.xml中添加依赖包

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional></dependency> |
2、创建配置文件（application.properties）

wx.appid = wx111111wx.redirectUri = https://www.baidu.com/wx.templateId = 1wx.first = 模板标题wx.remark = 模板备注wx.color = #000000sms.appid = 111111sms.appkey = bd3bfba026f711eaac3b005056b84de4sms.templateId = 1sms.sign = Jeff |
3、创建测试类1（WxSettings.java）

package com.jeff.config;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.stereotype.Component;@Component@ConfigurationProperties(prefix = "wx")public class WxSettings { private String appid; private String redirectUri; private Integer templateId; private String first; private String remark; private String color; public String getAppid() { return appid; } public void setAppid(String appid) { this.appid = appid; } public String getRedirectUri() { return redirectUri; } public void setRedirectUri(String redirectUri) { this.redirectUri = redirectUri; } public Integer getTemplateId() { return templateId; } public void setTemplateId(Integer templateId) { this.templateId = templateId; } public String getFirst() { return first; } public void setFirst(String first) { this.first = first; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; } public String getColor() { return color; } public void setColor(String color) { this.color = color; } @Override public String toString() { return "WxSettings [appid=" + appid + ", redirectUri=" + redirectUri + ", templateId=" + templateId + ", first=" + first + ", remark=" + remark + ", color=" + color + "]"; }} |

5、创建测试类（MyController.java）

6、打开浏览器访问 http://localhost:8080/myTest，控制台输出结果
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
