How to use Log4J2 composite configuration with Spring Boot

Deadly 提交于 2019-12-06 02:33:00
I am using Spring Boot 2.0.1 starter with log4j2 using following POM. WAR file is hosted in Tomcat 8 (instead of using embedded tomcat). Application logs are written to console instead of writing to log file. Apparently Spring Boot's XML configuration is overwrites the one configured in application. POM: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org

问题 I'm using log4j2, and running multiple instances of the same code in different processes (ie different JVMs) at the same time. I'd like all processes to log to the same file, interleaved How can I configure (via log4j2.xml) to output the PID, so that the different processes can be distinguished in the logs? 回答1: Perhaps MDC can help you. Try this: Java : import java.lang.management.ManagementFactory; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import

Log4j2 api cannot find Log4j2 core in OSGi environment

问题 I'm trying to use log4j2 OSGi bundles, but it seems log4j2 api cannot find log4j2 core in an OSGi environment. I'm continuously getting the following exception : ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console I found the same exception discussed in few places but still I could not figure out this issue. Isuspect I'm getting this issue because log4j2 api cannot find the log4j-provider

Redirect Jersey JUL logging to Log4j2

人盡茶涼 提交于 2019-12-05 22:44:11
I need to redirect Jersey request/response log to my log4j2. I have Jersey logging enabled by using this code on my ApplicationJAXRS extends Application : @Override public Set<Class<?>> getClasses() { return new HashSet<Class<?>>() {{ add(LoggingFilter.class); }}; } It seems that Jersey uses JUL (Java Logging) internally and the default output is STDOUT. At this moment I can see the STDOUT on Eclipse Console. The Log4j2 documentation have a section about JDK Logging Adapter . It says To use the JDK Logging Adapter, you must set the system property java.util.logging.manager to org.apache

Using Syslog's unix socket with Log4J2

情到浓时终转凉″ 提交于 2019-12-05 20:31:20
问题 I would like to send the logs of an application on a rsyslog server using the client protocol : Unix socket. Both application and rsyslog server are on the same machine. I've been comparing different logging tools : Log4J, Logback and Log4J2. Log4J's Syslog appender doesn't permit it natively. A solution is to use Syslog4J and configure our Syslog4JAppender this way : <appender name="mySyslogAppender" class="org.productivity.java.syslog4j.impl.log4j.Syslog4jAppender"> <param name="protocol"

I am using log4j 1.2 with commons-logging. Now I am trying to upgrade it to log4j2. But how to use log4j2 with commons-logging to initialize log4j2.
