springboot如何使用@ConfigurationProperties封装配置文件

springboot如何使用@ConfigurationProperties封装配置文件

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@CuuvFENgWonfigurationProperties，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

org.springframework.boot

spring-boot-configuration-processor

true

2、创建配置文件（application.properties）

wx.appid = wx111111

wx.redirectUri = https://baidu.com/

wx.templateId = 1

wx.first = 模板标题

wx.remark = 模板备注

wx.color = #000000

sms.appid = 111111

sms.appkey = bd3bfba026f711eaac3b005056b84de4

sms.templateId = 1

sms.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 tehttp://mplateId;

}

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 + "]";

}

}

4、创建测试类2（SmsSettings.java）

package com.jeff.config;

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

import org.springframework.stereotype.Component;

@Component

@ConfigurationProperties(prefix = "sms")

public class SmsSettings {

private String appid;

private String appkey;

private Integer templateId;

private String sign;

public String getAppid() {

return appid;

}

public void setAppid(String appid) {

this.appid = appid;

}

public String getAppkey() {

return appkey;

}

public void setAppkey(String appkey) {

this.appkey = appkey;

}

publhttp://ic Integer getTemplateId() {

return templateId;

}

public void setTemplateId(Integer templateId) {

this.templateId = templateId;

}

public String getSign() {

return sign;

}

public void setSign(String sign) {

this.sign = sign;

}

@Override

public String toString() {

return "SmsSettings [appid=" + appid + ", appkey=" + appkey + ", templateId=" + templateId + ", sign=" + sign

+ "]";

}

}

5、创建测试类（MyController.java）

package com.jeff.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestControlhttp://ler;

import com.jeff.config.SmsSettings;

import com.jeff.config.WxSettings;

@RestController

public class MyController {

@Autowired

private WxSettings wx;

@Autowired

private SmsSettings sms;

@Rehttp://questMapping("myTest")

public String myTest() {

System.out.println(wx.toString());

System.out.println(sms.toString());

return "success";

}

}

6、打开浏览器访问 http://localhost:8080/myTest，控制台输出结果
