The best practice and performance optimization of JBoss Logging 3 framework

The best practice and performance optimization of JBoss Logging 3 framework Overview JBoss Logging is an open source framework for Java applications to provide logging functions.It is based on the JDK14 logging API and provides additional function and performance optimization.This article will introduce the best practice and performance optimization skills of the JBoss Logging 3 framework to help developers better use the framework. Best Practices 1. Use the appropriate log level: When recording logs, it is important to choose the appropriate log level.Depending on the log level, the logs can be divided into debug, info, warn, error, and fata.Debug level is used for debugging and detailed log records, info levels for informatic messages, warn is used to warn, ERROR is used for error logs, and FATAL indicates that the system cannot be recovered seriously.Determining the appropriate log level can improve the efficiency and readability of log records. 2. Use lazy loading message: When constructing a log statement, try to load messages as much as possible, so as to avoid unnecessary string stitching operations.For example, write log statements in the following ways: logger.error ("Error Occurred: {}", () -> GENATEERRORMESSAGE ()).In this way, only in the case of the log level is ERROR, the GenerateRRORMESSAGE () method will be called. 3. Use MDC and NDC: Mapped Diagnostic Context (MDC) and Nested Diagnostic Context (NDC) are powerful features provided by JBoss Logging.MDC allows developers to store and access custom key values on data throughout the thread range, and NDC allows developers to create a specific diagnostic context for each thread in the multi -threaded environment.These functions can help developers better manage and track log information. Performance optimization 1. Reduce unnecessary log output: In the production environment, avoiding unnecessary or too frequent log messages can improve the performance of the application.When the log level is lower than the configuration level, you can first use the conditional statement to check the log record statement.For example, if (logger.iswarnenabled ()) {logger.warn ("warning message");}. 2. Enable asynchronous log records: JBoss Logging 3 framework supports asynchronous log records, which can be used to enable this function through configuration files.Asynchronous records can improve performance because it separates the log request from the main thread.This can reduce the delay of the main thread and make the application more efficient. 3. Formatal performance precautions: During the development process, it is important to reasonably choose a log formatting method that meets the performance requirements of the application.Simple formatization may be more efficient than complex formatting, and consume less CPU and memory resources.Try to avoid excessive use of place occupies and reduce unnecessary string stitching operations. Code example Below is a simple Java code example using the JBoss Logging 3 framework: import org.jboss.logging.Logger; public class MyLogger { private static final Logger logger = Logger.getLogger(MyLogger.class); public static void main(String[] args) { logger.info("Hello, JBoss Logging!"); } } In the above example, we obtain a logger instance through the method of `logger.getLogger ()` and use the `Info ()` method to record an information log message. in conclusion JBoss Logging 3 is a powerful log framework that helps developers to better manage and record log information of applications.By following the best practice and applied performance optimization skills, we can better use this framework and improve the performance of the application.I hope the guide provided in this article can help you better use the JBoss Logging 3 framework.
