问题 I have to log to separate log files depending on the service being used. So lets say I have service1 & service2 and the logs are going to service1.log & service2.log respectively. The issue is that there is some common code being used from both the services. Now how do I make the logs such that if the common code is called by any of the service then log into that specific log file. The way I am create the logger is private static final Logger logger = Logger.getLogger(ClassName.class); The

问题 Im creating a log file system. the log file will be in json format so a server can read it after but i dont think thats too important. What i need to know is can log4j be configured to write into to a file but without any tags like info,debug, timestamp etc in the file. I have looked here but this polutes the file with with other things. I want ONLY the data i write to show up in the file. I'd also like to set some kind of file rotation on the file if it gets too big after a max size is

问题 I am trying to do some development and I am using log4j to log some events into our database. I made a subclass of the JDBC appender so we can properly interface with our database. The log4j.properties file is located at src/main/resources.

问题 I'm working on a project and we want to handle our logging using log4j. I am running into some issues that I am not able to easily resolve looking at the log4j docs, or other documentation online. I get the basic idea of putting logging code throughout the codebase and then having the properties file assort the logged data into a hierarchy of appenders and how to write out to a file. That's fine. This basically allows me to create greppable log files in one hard coded folder, such as this:

问题 My code has a dependency on abc.jar file. This abc.jar file has a class called Logger, under the package org.apache.log4j , but this is not the Logger from Apache. I want to use Logger from Apache. I have added a dependency in maven for Apache's Logger. But the problem is that when I want to use Apache's Logger, it automatically picks up the Logger from abc.jar file. 回答1: To load class from specific JAR when both JAR has same Package with same class name. 1) You need to specify the path of

十一、springboot 配置log4j2以及打包成zip文件

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言 其实我们前面已经配置了日志，但是最近总感觉日志日志格式看的不舒服，并且每次打包都是一个jar 文件，lib都包含在jar 中，每次做很小的修改都需要重新替换jar文件，jar文件会比较大，传输起来比较慢。所以做一些改进。 配置log4j2 好了，废话不多说了，先来在Springboot中配置log4j2吧。 pom.xml springboot 项目默认的是使用logback 的，所以我们想要使用log4j ，需要将原来的logback 框架屏蔽掉，再引入log4j. 首先我们在pom.xml 文件中加入 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions><!-- 去掉默认配置 --> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId
