配置信息

#我的配置项
my:
  url: zhengxinghua.top
  data: 2021-12-31 14:21:00

第一种方式

@Value("${配置}")

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class SpringbootApplicationTests {

    //读取配置信息
    @Value("${my.url}")
    String  url  ;

    //读取配置星系
    @Value("${my.data}")
    String  data  ;

    @Test
    void contextLoads() {
        System.out.println();
        System.out.println("读取URL:"+url);
        System.out.println("读取Data"+data);
    }

}

第二种方式 configuration

1、pom.xml

        <!--读取配置-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <version>2.5.6</version>
        </dependency>
        
		<!--lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>

2、配置

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * @Author: 郑兴华
 * @CreateTime: 2021-12-31 15:41
 * @Description:
 */
@Data
@Component
@ConfigurationProperties(prefix = "my")
public class Content {
	//这里的名字和配置一致
    private  String url ;
    private  String data ;
}

3、输出

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class SpringbootApplicationTests {

    //读取配置信息
    @Autowired
    Content content ;



    @Test
    void readContent() {
        System.out.println();
        System.out.println("读取URL:"+content.getUrl());
        System.out.println("读取Data"+content.getData());
    }



}

结果
