業(yè)務(wù)場(chǎng)景：

把配置文件的信息，讀取并自動(dòng)封裝成實(shí)體類，可以使用@ConfigurationProperties，把同類的配置信息自動(dòng)封裝成實(shí)體類。

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

wx.appid = wx111111wx.redirectUri = https://www.baidu.com/wx.templateId = 1wx.first = 模板標(biāo)題wx.remark = 模板備注wx.color = #000000sms.appid = 111111sms.appkey = bd3bfba026f711eaac3b005056b84de4sms.templateId = 1sms.sign = Jeff3、創(chuàng)建測(cè)試類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;}@Overridepublic String toString() {return 'WxSettings [appid=' + appid + ', redirectUri=' + redirectUri + ', templateId=' + templateId + ', first='+ first + ', remark=' + remark + ', color=' + color + ']';}}4、創(chuàng)建測(cè)試類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;}public 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;}@Overridepublic String toString() {return 'SmsSettings [appid=' + appid + ', appkey=' + appkey + ', templateId=' + templateId + ', sign=' + sign+ ']';}}5、創(chuàng)建測(cè)試類（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.RestController;import com.jeff.config.SmsSettings;import com.jeff.config.WxSettings;@RestControllerpublic class MyController {@Autowiredprivate WxSettings wx;@Autowiredprivate SmsSettings sms;@RequestMapping('myTest')public String myTest() {System.out.println(wx.toString());System.out.println(sms.toString());return 'success';}}6、打開瀏覽器訪問 http://localhost:8080/myTest，控制臺(tái)輸出結(jié)果

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
