springboot使用@ConfigurationProperties封装配置文件-蒲公英云

springboot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 = wx111111
wx.redirectUri = https://www.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 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 + "]";
    }
}

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;
    }
    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;
    }
    @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.RestController;
import com.jeff.config.SmsSettings;
import com.jeff.config.WxSettings;
@RestController
public class MyController { 
    @Autowired
    private WxSettings wx;
    @Autowired
    private SmsSettings sms;
    @RequestMapping("myTest")
    public String myTest() { 
        System.out.println(wx.toString());
        System.out.println(sms.toString());
        return "success";
    }
}
