前言
- junit载入类
- 配置类读取配置文件
- .properties
- .yml
实现

AppTest.java文件
import static org.junit.Assert.assertTrue; import com.ruoyi.iot.aliyun.config.AliyunUserConstant; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; /** * Unit test for simple App. */ @RunWith(SpringRunner.class) @SpringBootTest(classes = AliyunUserConstant.class) public class AppTest { /** * Rigorous Test :-) */ @Test public void shouldAnswerWithTrue() { System.out.println(AliyunUserConstant.accessKey); assertTrue( true ); } }
读取配置yml/properties
方法一 @PropertySource + properties
aliyun-config.properties文件
aliyun.accessKey=123 aliyun.accessSecret=123 aliyun.iotInstanceId=123 aliyun.clientId=123 aliyun.host=123
AliyunUserConstant.java文件
import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Component; @Component @PropertySource(value = {"classpath:aliyun-config.properties"}) public class AliyunUserConstant { public static String regionId = ""; //public static String accessKey = ""; public static String accessKey = ""; public static String accessSecret = ""; public static String productKey = ""; public static String deviceName = ""; public static String instanceId = ""; public static String clientId = ""; public static String host = ""; @Value("${aliyun.regionId}") public void setRegionId(String regionId) { AliyunUserConstant.regionId = regionId; } @Value("${aliyun.accessKey}") public void setAccessKey(String accessKey) { AliyunUserConstant.accessKey = accessKey; } @Value("${aliyun.accessSecret}") public void setAccessSecret(String accessSecret) { AliyunUserConstant.accessSecret = accessSecret; } @Value("${aliyun.productKey}") public void setProductKey(String productKey) { AliyunUserConstant.productKey = productKey; } @Value("${aliyun.deviceName}") public void setDeviceName(String deviceName) { AliyunUserConstant.deviceName = deviceName; } @Value("${aliyun.instanceId}") public void setInstanceId(String instanceId) { AliyunUserConstant.instanceId = instanceId; } @Value("${aliyun.clientId}") public void setClientId(String clientId) { AliyunUserConstant.clientId = clientId; } @Value("${aliyun.host}") public void setHost(String host) { AliyunUserConstant.host = host; } }
方法二 @PropertySource + yml + YamlPropertySourceFactory
aliyun: accessKey: 123 accessSecret: 123 iotInstanceId: 123 clientId: 123 host: 123
AliyunUserConstant .java文件
import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Component; @Component //以下ok @PropertySource(value = {"classpath:application-aliyun-config.yml"},factory = YamlPropertySourceFactory.class) public class AliyunUserConstant { public static String regionId = "cn-shanghai"; //public static String accessKey = "xxxxxx"; public static String accessKey = ""; public static String accessSecret = "xxxxxx"; public static String productKey = "hf3fsfEX3CF"; public static String deviceName = "test_device"; public static String instanceId = "iot-06z00fu20bxiv4s"; public static String clientId = "123456"; public static String host = "iot-06z00fu20bxiv4s.amqp.iothub.aliyuncs.com"; @Value("${aliyun.regionId}") public void setRegionId(String regionId) { AliyunUserConstant.regionId = regionId; } @Value("${aliyun.accessKey}") public void setAccessKey(String accessKey) { AliyunUserConstant.accessKey = accessKey; } @Value("${aliyun.accessSecret}") public void setAccessSecret(String accessSecret) { AliyunUserConstant.accessSecret = accessSecret; } @Value("${aliyun.productKey}") public void setProductKey(String productKey) { AliyunUserConstant.productKey = productKey; } @Value("${aliyun.deviceName}") public void setDeviceName(String deviceName) { AliyunUserConstant.deviceName = deviceName; } @Value("${aliyun.instanceId}") public void setInstanceId(String instanceId) { AliyunUserConstant.instanceId = instanceId; } @Value("${aliyun.clientId}") public void setClientId(String clientId) { AliyunUserConstant.clientId = clientId; } @Value("${aliyun.host}") public void setHost(String host) { AliyunUserConstant.host = host; } }
YamlPropertySourceFactory.java文件
import org.springframework.boot.env.YamlPropertySourceLoader; import org.springframework.core.env.PropertySource; import org.springframework.core.io.support.EncodedResource; import org.springframework.core.io.support.PropertySourceFactory; import java.io.IOException; /** * @author Erwin Feng * @since 2020/8/13 */ public class YamlPropertySourceFactory implements PropertySourceFactory { @Override public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException { // 返回 yaml 属性资源 return new YamlPropertySourceLoader() .load(resource.getResource().getFilename(), resource.getResource()) .get(0); } }
方法三 @ConfigurationProperties + yml
方法四 @ActiveProfiles + yml
@ActiveProfiles(value = "aliyun-config") // 载入application-aliyun-config.yml文件
