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

Replacement for Logback LevelRemappingAppender in Spring Boot 2?

由 吃可爱长大的小学妹 提交于 2020-01-02 04:41:06
问题 I'm migrating an application from Spring Boot 1.x to 2.x and I found some entries in the logback configuration which use a LevelRemappingAppender , like this: <appender name="DEBUG_LEVEL_REMAPPER" class="org.springframework.boot.logging.logback.LevelRemappingAppender"> <destinationLogger>org.springframework.boot</destinationLogger> </appender> org.springframework.boot.logging.logback.LevelRemappingAppender doesn't exist in Boot 2 and I can't find a replacement nor any mention in the migration

Logback的AsyncAppender与RollingFileAppender流程解析

由 主宰稳场 提交于 2020-01-01 22:45:08
近期工作中涉及到文件记录、文件翻转等操作，思考有没有成熟的代码以便参考. 因此，第一时间就联想到Logback的AsyncAppender以及RollingFileAppender. AsyncAppender:通过队列储存日志事件，启动Worker线程读取日志事件并写入关联的Appender中； RollingFileAppender:当日志文件满足设定的翻滚条件时，对文件进行翻滚操作. PS: AsyncAppender可以与RollingFileAppender结合使用，提升日志事件写入效率. 1 AsyncAppender public class AsyncAppender extends AsyncAppenderBase<ILoggingEvent> { // 省略部分功能 boolean includeCallerData = false; protected boolean isDiscardable(ILoggingEvent event) { Level level = event.getLevel(); return level.toInt() <= Level.INFO_INT; } protected void preprocess(ILoggingEvent eventObject) { eventObject

Make Akka aware of Play's logback configuration

由 元气小坏坏 提交于 2020-01-01 09:28:11
问题 How do I make Akka aware of Play's logback config (application-logger.xml)? In my case it is completely ignored: The log is ONLY printed to stdout. I expect it to be logged to the File-Appender defined in application-logger.xml It does not make a difference if I rename application-logger.xml to logback.xml. Actor-class: class Dispatcher extends Actor with ActorLogging { // prints to stdout ONLY: log.error("[akka-logger] dispatch started...") } conf/application.conf: play { akka { #log-config

When not to use AsyncAppender in logback by default

由 我的未来我决定 提交于 2020-01-01 08:26:24
问题 Logback supports using an async appender with the class ch.qos.Logback.classic.AsyncAppender and according to the documentation, this will reduce the logging overhead on the application. So, why not just make it the default out of the box. What usecases are better served by using a sync appender. One problem I can see with the Async appender is that the log messages will not be chronological. Are there any other such limitations? 回答1: The AsyncAppender acts as a dispatcher to another appender

Embedded Tomcat logging over logback / sl4j

由 て烟熏妆下的殇ゞ 提交于 2020-01-01 05:36:07
问题 How can I make an embedded tomcat write its logs over logback? I found some info about using a standalone tomcat with log4j. But how does the setup look like for an embedded tomcat and logback? These are the maven dependencies: <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>${logback.version}</version> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-core</artifactId> <version>${tomcat.version}<

Externalized the location of logback.xml in Spring Boot using application.properties

由 无人久伴 提交于 2020-01-01 04:43:07
问题 How can I customized the location of logback.xml in Spring Boot using application.properties? I tried below but is not working. application.properties logging.config = /home/dev-01/Documents/logback.xml It is working if the logback.xml is located in the resource folder, but not working if it is located outside the project. It is also working if the I supply as environment variable like -Dlogging.config=/home/dev-01/Documents/logback.xml 回答1: Below construct worked for me (but I used relative

play framework logback custom layout

由 馋奶兔 提交于 2020-01-01 04:19:26
问题 I am trying to use a custom layout class for play framework 2.0 logback logging. First, I defined a custom layout class in package utils: package utils; public class MonitorLayoutForLogback extends LayoutBase<ILoggingEvent> { ... } In my conf/logging.xml file, I put: <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"> <layout class="utils.MonitorLayoutForLogback"> <param name="programName" value=
