RocketMQ屏蔽掉一直打的info日志

在测试本地代码问题时，控制台一直在打mq的连接日志，导致在真正测试时查看日志很不方便。

那么，就需要屏蔽掉这些没有意义的日志。其实就是修改mq的打印日志级别为error级别。

如何处理呢？

就是要重写包org.apache.rocketmq.client.log的内容。

使用注意点

• 重写的包要在/src/main/java下，与你所在的工程包是平级；

• 包名必须是org.apache.rocketmq.client.log，否则不生效。原因在于是重写mq底层的代码，那么包名就要保持一致；

• 修改的地方有两处：

  • 新增ClientLogger这个类；

  • 在工程包启动类中要新增一段修改日志级别的main方法；

新增的ClientLogger类

 public class ClientLogger {     public static final String CLIENT_LOG_USESLF4J = "rocketmq.client.logUseSlf4j";     public static final String CLIENT_LOG_ROOT = "rocketmq.client.logRoot";     public static final String CLIENT_LOG_MAXINDEX = "rocketmq.client.logFileMaxIndex";     public static final String CLIENT_LOG_FILESIZE = "rocketmq.client.logFileMaxSize";     public static final String CLIENT_LOG_LEVEL = "rocketmq.client.logLevel";     public static final String CLIENT_LOG_ADDITIVE = "rocketmq.client.log.additive";     public static final String CLIENT_LOG_FILENAME = "rocketmq.client.logFileName";     public static final String CLIENT_LOG_ASYNC_QUEUESIZE = "rocketmq.client.logAsyncQueueSize";     public static final String ROCKETMQ_CLIENT_APPENDER_NAME = "RocketmqClientAppender";     private static final InternalLogger CLIENT_LOGGER;     private static final boolean CLIENT_USE_SLF4J = Boolean.parseBoolean(System.getProperty("rocketmq.client.logUseSlf4j", "false"));     private static Appender rocketmqClientAppender = null; ​ ​     public ClientLogger() {     } ​ ​     private static synchronized void createClientAppender() {         String clientLogRoot = System.getProperty("rocketmq.client.logRoot", System.getProperty("user.home") + "/logs/rocketmqlogs");         String clientLogMaxIndex = System.getProperty("rocketmq.client.logFileMaxIndex", "10");         String clientLogFileName = System.getProperty("rocketmq.client.logFileName", "rocketmq_client.log");         String maxFileSize = System.getProperty("rocketmq.client.logFileMaxSize", "1073741824");         String asyncQueueSize = System.getProperty("rocketmq.client.logAsyncQueueSize", "1024");         String logFileName = clientLogRoot + "/" + clientLogFileName;         int maxFileIndex = Integer.parseInt(clientLogMaxIndex);         int queueSize = Integer.parseInt(asyncQueueSize);         Layout layout = LoggingBuilder.newLayoutBuilder().withDefaultLayout().build();         rocketmqClientAppender = LoggingBuilder.newAppenderBuilder().withRollingFileAppender(logFileName, maxFileSize, maxFileIndex).withAsync(false, queueSize).withName("RocketmqClientAppender").withLayout(layout).build();         Logger.getRootLogger().addAppender(rocketmqClientAppender);     } ​ ​     private static InternalLogger createLogger(String loggerName) {         String clientLogLevel = System.getProperty("rocketmq.client.logLevel", "INFO");         boolean additive = "true".equalsIgnoreCase(System.getProperty("rocketmq.client.log.additive"));         InternalLogger logger = InternalLoggerFactory.getLogger(loggerName);         InnerLogger innerLogger = (InnerLogger) logger;         Logger realLogger = innerLogger.getLogger();         if (rocketmqClientAppender == null) {             createClientAppender();         } ​ ​         realLogger.addAppender(rocketmqClientAppender);         realLogger.setLevel(Level.toLevel(clientLogLevel));         realLogger.setAdditivity(additive);         return logger;     } ​ ​     public static InternalLogger getLog() {         return CLIENT_LOGGER;     } ​ ​     static {         InternalLoggerFactory.setCurrentLoggerType("inner");         CLIENT_LOGGER = createLogger("RocketmqClient");         createLogger("RocketmqCommon");         createLogger("RocketmqRemoting");     } }

启动类main方法调整mq日志级别

如这样的调整：

 public static void main(String[] args) {         System.setProperty("rocketmq.client.logLevel", "ERROR");         SpringApplication.run(StationApplication.class, args); }
