针对不同环境下,可以配置不同的配置文件,如application-dev.properties、application-test.properties。
采用spring.profiles.active
属性来区分不同的应用环境。
@Data
@Component
@ConfigurationProperties(prefix = "log")
@PropertySource(name = "log", value = "classpath:log-${spring.profiles.active:}.properties", factory = SystemPropertySourceFactory.class)
public class LogConfig implements Serializable {
private static final long serialVersionUID = 1L;
private String tableName = "comm_log";
//private String logType = "LX2";
private String host;
private int port;
private int maxThreads = 20;
private int saveMode = 0;
private boolean saveLog = true;
private String topic = "TOPIC_COMMON_LOG";
private String defaultErrCode;
private boolean openInTable = false;
private String inTableName;
private String remoteUrl;
private String namesrvAddr;
private String producerGroupName;
private String instanceName;
private int sendTimeout;
}
若spring.profiles.active为空,则该值为空字符串。
/**
* 针对自定义配置文件的一个多环境配置逻辑
*
*/
public class SystemPropertySourceFactory implements PropertySourceFactory {
@Override
public PropertySource<?> createPropertySource(String name, EncodedResource resource)
throws IOException {
String fileSuffix = "";
try {
String filename = resource.getResource().getFilename();
fileSuffix = filename.substring(filename.lastIndexOf("."));
resource.getResource().getFile();
return new ResourcePropertySource(name, resource);
} catch (Exception e) {
InputStream inputStream = SystemPropertySourceFactory.class.getClassLoader()
.getResourceAsStream(name + fileSuffix);
//转成resource
InputStreamResource inResource = new InputStreamResource(inputStream);
return new ResourcePropertySource(new EncodedResource(inResource));
}
}
}
若spring.profiles.active=dev有配置,但是没有这个配置文件(例:log-dev.properties),则默认读取log.properties。若spring.profiles.active无配置,则默认读取log.properties。
思路:将spring.profiles.active 属性设置到System环境变量。则非Spring环境可从System环境变量中获取该值。
@Component
public class ServerInfo implements ApplicationListener<WebServerInitializedEvent> {
private static final String SPRING_PROFILES_ACTIVE = "spring.profiles.active";
@Override
public void onApplicationEvent(WebServerInitializedEvent event) {
//设置系统变量
System.setProperty(SPRING_PROFILES_ACTIVE, this.getProfileActive());
}
/**
* 获取spring.profiles.active属性值
* @return
*/
public String getProfileActive() {
return env.getProperty(SPRING_PROFILES_ACTIVE, "");
}
}
