问题 I have a Tomcat server running a Spring-based servlet. I've set up [project root]/src/log4j.properties file as below: # Root logger option log4j.rootLogger=WARN, stdout # Redirect log messages to console log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%-5p %d{HH:mm:ss} %m [%c{3}:%L]%n log4j.logger.com.martincarney.bugTracker=DEBUG log4j

Hibernate 4 Wildfly 8 logging not working

由 蓝咒 提交于 2020-01-03 16:12:21
问题 How do I get hibernate 4 to log via logback? I have a war deployed to wildfly 8 final, and I am using slf4j with logback. The logging setup is working 100% in the application with both the console appender and file appender working as intended. Here is what I did to get slf4j + logback working: Excluded the logging subsystem with jboss-deployment-structure.xml in WEB-INF: <?xml version="1.0" encoding="UTF-8"?> <jboss-deployment-structure> <deployment> <exclude-subsystems> <subsystem name=

SLF4J-Log4J does not appear to have disabled logging

问题 It seems that although the log level was set to INFO, SLF4J is still evaluating the expression. package com.ab.test.slf4j; import org.apache.log4j.PropertyConfigurator; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class SimpleTest { static final Logger logger = LoggerFactory.getLogger(SimpleTest.class); public static void main(String[] args) { PropertyConfigurator.configure("log4j.properties"); logger.debug("Test " + testEnter()); logger.debug("Test {}", testEnter()); }

spring-boot笔记--日志

三、Spring Boot日志 1、日志框架 日志的抽象层：JCL、SLF4J、jboss-logging 日志的实现：Log4j JUL、Log4j2 Logback Spring Boot：底层是Spring、Spring默认是JCL、而Spring Boot选用SLF4j和logback 2、SLF4j 2.1 系统中如何使用 开发的时候，日志记录方法的调用应该调用日志抽象层的方法 首先导入slf4j的jar和logback的jar，可以查看下图 import org . slf4j . Logger ; import org . slf4j . LoggerFactory ; public class HelloWorld { public static void main ( String [ ] args ) { Logger logger = LoggerFactory . getLogger ( HelloWorld . class ) ; logger . info ( "Hello World" ) ; } } 每一个日志都有自己的配置文件，使用slf4j后还是使用日志框架自己本身的配置文件 2.2 多个日志框架统一转成slf4j 如何让系统中所有的日志统一到slf4j 首先将系统的其它日志框架排除 用中间包来替换原来的日志框架 导入slf4j来实现统一框架 2

Scala and SLF4J :: pass multiple parameters

由 自作多情 提交于 2020-01-03 08:48:13
问题 Having the following code: log.info("parameters {} and {}", param1, param2) compiles and works well with SLF4J in Scala However if I want to pass more arguments, I need to use Array: log.info("parameters {} and {} and {}", Array(param1, param2,param3)) which simply substitutes first parameter with array.toString and leaves rest of parameters unbound. The following code log.info("parameters {} and {} and {}", Array(param1, param2,param3) : _*) doesn't compile, because of: error: overloaded

slf4j with glassfish is ignoring logback

由 爷，独闯天下 提交于 2020-01-02 08:28:27
问题 In a java-ee maven project I have I'm wanting to use slf4j with logback, however I believe inclusion of the 'glassfish-embedded-all' artifact from org.glassfish.extras is causing the JDK14LoggerAdapter to be used instead. Removing this artifact causes the logging to work as expected, however causes test failures due to java-ee api issues as described on this question - Testing against Java EE 6 API. The exact pom entry causing the problem, I believe, is: <dependency> <groupId>org.glassfish

Practical use of Logback context selectors

由 ⅰ亾dé卋堺 提交于 2020-01-02 06:06:14
问题 The documentation on Logback logging separation indicates that I can use context selectors to create different logging configurations on the same JVM. Somehow a context selector will allow me to call LoggerFactory.getLogger(Foo.class) and, based upon the context, I will get a differently configured logger. Unfortunately the examples only deal with JNDI in the context of a specially configured web server such as Tomcat or Jetty. I want to know how I can practically use a context selector
