问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . It seems that log4j has some class loading issues (among others) and it seems to me the trend is to move out of log4j toward slf4j. (Hibernate stopped using the first in favor of the latter) Is it true? What are the main issues in log4j that slf4j solves? Is slf4j the final

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . My question seems to be easily answerable, but there are several good solutions. I like to choose the 'best' one. Available frameworks (feel free to suggest more): Androlog SLF4J Android Log4J - Android Pros/Cons: Androlog: Pro: Similar to Android logging framework, so there are only small changes in the

3、log4j2 　　log4j2与log4j发生了很大变化，不兼容。log4j仅仅作为一个实际的日志框架，slf4j、commons-logging作为门面统一各种日志框架的混乱格局，现在log4j2也想跳出来当门面，也想统一大家。日志越来越乱了 log4j-api：作为日志接口层，用于统一底层日志系统。 log4j-core：作为上述日志接口的实现，是一个实际的日志框架。 　　3.1、maven依赖 1 <dependency> 2 <groupId>org.apache.logging.log4j</groupId> 3 <artifactId>log4j-api</artifactId> 4 <version>2.2</version> 5 </dependency> 6 <dependency> 7 <groupId>org.apache.logging.log4j</groupId> 8 <artifactId>log4j-core</artifactId> 9 <version>2.2</version> 10 </dependency> 　　3.2、使用方式 编写log4j2.xml配置文件（目前log4j2只支持xml、json、yuml，不再支持properties） 1 <?xml version="1.0" encoding="UTF-8"?> 2

Log4j Logging to a Shared Log File

由 北战南征 提交于 2019-12-18 05:55:44
问题 Is there a way to write log4j logging events to a log file that is also being written to by other applications. The other applications could be non-java applications. What are the drawbacks? Locking issues? Formatting? 回答1: Log4j has a SocketAppender, which will send events to a service, which you can implement yourself or use the simple implementation bundled with Log4j. It also supports syslogd and the Windows event log, which may be useful in trying to unify your log output with events

Java Logging: Log4j Version2.x: show the method of an end-client caller (not an intermediate logging helper method)

由 ＊爱你＆永不变心＊ 提交于 2019-12-18 05:47:33
问题 The following 3 posts offer answers for how to use an intermediate logging helper and still get the underlying logger to report from the method of a client to that logging helper (rather than reporting the logging helper method as the source): Java Logging: show the source line number of the caller (not the logging helper method) Calling log4j's log methods indirectly (from a helper method) Printing the "source" class in a log statement with a log4j wrapper But the seem to only offer answers

How to turn off log4j warnings?

由 不问归期 提交于 2019-12-18 05:40:49
问题 I'm running a Java app that depends on a few libraries (Axis2) which use log4j. I don't use log4j and don't have any configuration file. I'd like to just completely disable log4j and squelch any and all warnings that it spits out. Right now, when I run my app, when I call one of the library's methods, I see: log4j:WARN No appenders could be found for logger (org.apache.axis2.deployment.FileSystemConfigurator). log4j:WARN Please initialize the log4j system properly. Is there some static log4j

Configuring log4j property file to store in mysql Database

问题 It's been a while that I began with log4j; pretty cool logging framework. I've done other type of logging like Console and File Logging. So trying for DB Adapters with mysql for Database logging. Accordingly, I've created following property file named log4j.properties as - # Define the root logger with appender file log4j.rootLogger = DEBUG, DB # Define the DB appender log4j.appender.DB=org.apache.log4j.jdbc.JDBCAppender # Set JDBC URL log4j.appender.DB.URL=jdbc:mysql://localhost:3306/test #

spring mvc log日志由log4j桥接至log4j2

由 冷暖自知 提交于 2019-12-18 05:19:11
简介 spring mvc的日志系统可以配置很多版本，比如log4j、log4j2、logback等等，在参考资料中介绍了Spring mvc如何直接集成log4j2，我们这里介绍的是，如何将原系统中的log4j改为使用log4j2. 操作步骤 1. 删除原Spring mvc中对log4j的依赖 <exclusions> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> </exclusions> 2、添加log4j2的依赖，其中og4j2的版本我选择的是， <log4j2.version>2.11.2</log4j2.version>，其中jul（java util logging）jcl (apache commons-logging)的依赖可以不用添加 <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>${log4j2.version}</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId>
