log4j2

I need to create logs with key value pairs as below. Is there any support in PatternLayout to do this for the static fields in a thread like log_level, class_name, event_id etc with the log4j2.xml. Sample log: 2014-06-18 11:57:46,719 log_level="INFO" class_name="com.abc.dgl.App:main(158)" name="Application start event" event_id="b88f7ea0-4cb1-438f-a728-ac7c2bdac578" app="Test App" severity="info" action="loaded sfor file processing" desc="props was read and loaded" result="success" reason="abc" transaction_id="b88f7ea0-4cb1-438f-a728-ac7c2bdac578" Yes, this is possible. You can either use a

I have those specific requirements : Need to be able to log in FATAL level Need to use SLF4J Need to use Log4j2 Right now, here's my implementation : final Logger logger = LoggerFactory.getLogger(HelloWorld.class); final Marker marker = MarkerFactory.getMarker("FATAL"); logger.error(marker, "!!! Fatal World !!!"); Here's my PatternLayout (in yaml) : PatternLayout: Pattern: "%d{ISO8601_BASIC} %-5level %marker [%t] %logger{3.} - %msg%n" Here's my log output : 20150506T155705,158 ERROR FATAL [main] - !!! Fatal World !!! Do you have any idea about how to efficiently to remove the "ERROR" from the

I am attempting to set up asynchronous logging (for performance reasons) within REST web methods that currently run in a liberty profile server. In order to do this, I have set up the following property: System.setProperty("Log4jContextSelector", "org.apache.logging.log4j.core.async.AsyncLoggerContextSelector"); My problem is that no matter where I do this, sometimes it works and logging is very fast, and sometimes it doesn't. I have tried (a) in the constructor for the class containing all the REST web methods (b) in the filter doFilter method that gets called prior to the REST method (c) in

I am trying to use JUL Adapter to delegate Java Util Logging to Log4j2. More precisely, any third-party library that use JUL to generate logs, should be delegated to Log4j2. As a simple exercise, I created a standalone application that uses a library (I created this library for testing purposes, it generates logs using JUL) to test the JUL Adapter . When I change the log manager as described here I can see the effects. And it works fine. Hers's the code: import org.apache.logging.log4j.LogManager; import com.ah.loggen.LogGenerator; public class TestLogging { static { System.setProperty("java

I am working on a web application based on spring boot and want to use log4j2 as the logger implementation. Everything works fine with the logging configuration defined in a log4j2-spring.xml file. What is not working: I want to use property placeholders in the log4j2-spring.xml file that should be resolved from properties defined in the application.yml file used for configuring spring boot. Is this possible? If yes, how? Direct substitution of properties in log4j2-spring.xml via property placeholder is not possible as the log4j2-spring.xml is outside the ambit of Spring, and used purely for

Shiro 简介 1. 什么是 shiro shiro是 apache的一个开源框架，是一个权限管理的框架，实现 用户认证、用户授权。 spring中有 spring security (原名 Acegi)，是一个权限框架，它和 spring依赖过于紧密，没有 shiro使用简单。 shiro不依赖于 spring， shiro不仅可以实现 web应用的权限管理，还可以实现 c/s系统， 分布式系统权限管理， shiro属于轻量框架，越来越多企业项目开始使用 shiro。 2. 在应用程序角度来观察如何使用 Shiro完成工作 (图 01) Subject：主体，代表了当前“用户”，这个用户不一定是一个具体的人，与当前应用交互的任何东西都是 Subject，如网络爬虫，机器人等；即一个抽象概念；所有 Subject 都绑定到 SecurityManager，与 Subject的所有交互都会委托给 SecurityManager；可以把 Subject认为是一个门面； SecurityManager才是实际的执行者； SecurityManager：安全管理器；即所有与安全有关的操作都会与 SecurityManager 交互；且它管理着所有 Subject；可以看出它是 Shiro 的核心，它负责与后边介绍的其他组件进行交互，如果学习过 SpringMVC，你可以把它看成
