问题 I am trying to create a custom appender for log4j 2.0, but am having issues getting my log4j configuration to recognize the appender. I know log4j 2.0 doesnt support packages in configuration attributes. So I tried, as suggested here, running the code with plain javac but even then it gives this error: 2015-03-11 18:47:35,281 ERROR Error processing element Test: CLASS_NOT_FOUND 2015-03-11 18:47:35,307 ERROR Unable to locate appender test1 for logger Here is my custom appender: @Plugin(name =

问题 I'm trying to run this example, but I have some problems with configuration. I copied log4j-jms.properties , jndi.properties , Log4jJMSAppenderExample.java ProjectJMS | \_ src | \_ Log4jJMSAppenderExample.java | \_ jndi.propeties \_ log4j-jms.properties and run activemq in my console. When I ran my example I got log4j:WARN No appenders could be found for logger (org.apache.activemq.transport.WireFormatNegotiator). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http:/

Correct way to stop custom logback async appender

廉价感情. 提交于 2019-12-04 10:12:04
I've created Amazon SQS and SNS logback appenders using the Amazon's Java SDK. The basic appenders use the synchronous Java APIs, but I've also created asynchronous versions of both by extending the ch.qos.logback.classic.AsyncAppender class. Stopping the logback logger context with the async appenders does not work as expected though. When the context is stopped, all async appenders try to to flush remaining events before exiting. The problem originates from ch.qos.logback.core.AsyncAppenderBase#stop method, which interrupts the worker thread. The interrupt is triggered while the Amazon SDK

Log4j2's FailoverAppender Error: appender Failover has no parameter that matches element Failovers

泄露秘密 提交于 2019-12-04 06:53:34
When I compile my spring 3.2.9 web application using log4j 2.1, this error appears in the console: 2015-02-02 12:08:25,213 ERROR appender Failover has no parameter that matches element Failovers What I understand is that the element "Failovers" does not exist inside the element "Failover", right? Why would this happen? I don't see whats wrong since I have the same configuration as the log4j2 manual. I have this configuration in my log4j2.xml: <?xml version="1.0" encoding="UTF-8"?> <Configuration name="vcr-log4j2-config" status="debug"> <Appenders> <Console name="STDOUT" target="SYSTEM_OUT">

how to use Kafka 0.8 Log4j appender

I am trying to run Kafka-0.8 Log4j appender and I am unable to make it. I want my application to send log directly to kafka via Log4j appender. Here is my log4j.properties. I couldn`t find any proper encoder, so I just configure it to use default encoder. (e.g I commented the line.) log4j.rootLogger=INFO, stdout, KAFKA log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n log4j.appender.KAFKA=kafka.producer.KafkaLog4jAppender log4j.appender.KAFKA.layout=org.apache

Configuring log4net appenders via XML file *and* code

牧云@^-^@ 提交于 2019-12-02 03:35:21
I started to play with log4net today and so far, I really like it. In order to preserve our current logging functionality, the app needs to create a new log file whenever the application is started. The log file name has the date and time stamp encoded in it. Currently, I've got log4net configured via an XmlConfigurator , which works great, except that the filename for my RollingFileAppender is hardcoded in the configuration XML file. I'd like to continue to use the XmlConfigurator , but after calling Configure() , I want to get at the RollingFileAppender and, in code, change its file value to

What are the available options to retrieve Spring-managed beans in a Log4J Appender inside a Spring-managed web application?

*爱你&永不变心* 提交于 2019-12-02 00:27:15
问题 My current build lead has a great idea in theory - construct a custom Log4J appender that takes in Spring-managed beans and uses them to log errors to various other sources than just the standard log file. However, other than creating a singleton initialized at startup with the application context (code in just a moment), I can't seem to think of any other options of retrieving a Spring managed bean in a Log4J appender. public class SpringSingleton implements ApplicationContextAware { private
