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

由 ﹥＞﹥吖頭↗ 提交于 2019-12-01 22:35:23
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 static ApplicationContext context; public SpringSingleton() { super(); } public static

I would like to use an INFO log level for APPENDER_STDOUT , and a DEBUG log level for

How to use Pattern layout with SocketAppender

由 ￣綄美尐妖づ 提交于 2019-11-30 09:48:52
问题 I read org.apache.log4j.net.SocketAppender does not use a Layout. But, I really need to format my logs and I need to use a ConversionPattern. Does anybody know an alternate to this? I have to use some kind of SocketAppender. Thanks 回答1: The logs sent through a SocketAppender are serialized and can't have a layout specified to it until it is deserialized. On the remote host you'll have access to all the same information and should be able to specify the layout that the logs are printed in. So
