log4j2

问题 I need help with an issue I have no idea how to resolve. Your help will be greatly appreciated. I just added log4j2 jars (log4j-api-2.10.0.jar, log4j-core-2.10.0.jar) to my Web app and it started running into this problem in my dev. Later I added log4j-web-2.10.0.jar and tried, it still fails with the same message. Here's my environment: IDE: Eclipse Oxygen2 JDK: 1.8.0_162 Jetty (embedded in Eclipse): jetty-9.2.z-SNAPSHOT OS: Win 10 (64bit) Framework: GWT 2.8.2 Stack trace (partial): [WARN]

问题 We have multiple spring mvc applications(war) deployed to weblogic 12c. Each was has dependency to one or two application lib(jar) packaged with it. What we want to do is, create application(war) specific log file and configure it to rotate based on some size and archive it old logs file to some folder. How it can be achieved in log4j2? 回答1: Create separate log4j2.xml configuration files for each web application, each with different target log files. Put the log4j2.xml configuration file in

问题 I am using Hibernate 4.3.7.Final and Log4j2 in my Spring MVC webapp, published via Tomcat 7. All configuration is done via JavaConfig (i.e. there is no web.xml or other XML config files). By default the Hibernate logging does not go through Log4j, for reasons explained in the Apache wiki. In order to resolve this I need to create a system setting as follows: System.setProperty("org.jboss.logging.provider", "slf4j"); As my application is a webapp there is no Main thread, and as a result I an

问题 When I run my app on eclipse IDE, everything goes ok, but when I package it I get that exception. Then, if I package it again with jackson's dependencies in my pom I don't have any problem, but I would like to know why when I run it on my IDE even without jackson's dependencies no exception is thrown. The dependency tree is: [INFO] +- org.hibernate:hibernate-entitymanager:jar:5.0.2.Final:compile [INFO] | +- org.jboss.logging:jboss-logging:jar:3.3.0.Final:compile [INFO] | +- org.hibernate

问题 In a Spring-Application I am trying to use Log4j2 instead of the default logging implementation Logback. So in my pom.xml I excluded spring-boot-starter-logging and included spring-boot-starter-log4j2 . So I am able to use Log4j2. But if I open now the Spring Boot Acuator endpoint localhost:8080/actuator/loggers I am not seeing all Loggers anymore. With Logback there were several hundred Loggers but with Log4j2 I am seeing only about 10. My question is: How can I see the full list of all
