由 允我心安 提交于 2019-12-23 02:28:32
问题 I'm getting the NoClassDefFoundError after executing my project's JAR file. Debugging with Eclipse works fine, but I get this error whenever I use the windows command java -jar myproject.jar since I installed JDK 1.7. It was working fine using Java 1.6. Here's the error log : Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Layout at program.Main.main(Main.java:20) Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Layout at java.net.URLClassLoader$1.run

问题 Log information is shown on console but not on the log file (the file is created but no content is added). What's wrong? Source: package mytest; import java.util.logging.Level; import java.util.logging.Logger; import org.apache.log4j.PropertyConfigurator; public class Main { public static void main(String[] args) { Logger log = Logger.getLogger(Main.class.getName()); log.setLevel(Level.ALL); log.info("A line)"); PropertyConfigurator.configure("log.properties"); log.info("Another line"); } }

[学习随笔]SpringMVC框架集成Log4j日志框架这里写自定义目录标题 Log4j简介 Log4j依赖添加 Log4j简介 log4j是Apache下的开源项目，主要功能为采集日志信息并输出打印。Log4j主要组件有如下三个。 （1）Logger：记录器，并提供细粒度划分，定义了不同的日志级别。这些日志级别的优先级如下： all<debug<info<warn<error<fatal<off. (2)Appender：Log4j允许把日志输出到不同的地方。Console，Files等。 (3)Layout：格式化日志输出方式 Log4j可以有两种配置方式，XML式或者.properties形式。xml式文件基本配置如下： // An highlighted block < ? xml version = "1.0" encoding = "UTF-8" ? > < Configuration status = "WARN" > < Appenders > < Concole name = "Console" target = "SYSTEM_OUT" > < PatternLayout pattern = "%d{HH:mm:ss:SSS}[%t]%-5level%logger{36}-%msg%n" > < / Console > < / Appenders > <

Log4j的使用

由 我与影子孤独终老i 提交于 2019-12-22 18:01:43
Log4j是由apache推出的开源免费日志处理的类库。 日志作用： （1）在项目中编写System.out.println();输出到控制台，当项目发布到tomcat后，没有控制台，不容易观察一些输出结果。 （2）log4j不仅能把内容输出到控制台，还能把内容输出到文件中，便于观察结果。 使用步骤： （1）导入log4j-xxx.jar。 （2）在src下新建log4j.properties(路径和名称都不允许改变) log4j输出级别 fatal（致命错误）>error(错误)>warn(警告)>info(普通信息)>debug（调试信息） pattern中常用的几个表达式 （1）%c 包名+类名 （2）%d{YYYY-MM-dd HH：mm：ss}时间 （3）%L 行号 （4）%m 信息 （5）%n 换行 来源： CSDN 作者： Heart of Ocean 链接： https://blog.csdn.net/weixin_43180675/article/details/103654585

In log4j2, how to configure renameEmptyFiles to be false for the RollingFile appender?

由 空扰寡人 提交于 2019-12-22 12:39:09
问题 I'm using log4j 2 and RollingFile appender: <RollingFile name="mylog" fileName="mylog.log" filePattern="mylog.log.%d{yyyy-MM-dd}.log"> <PatternLayout> <pattern>[%d] [%-5p] [%-8t] %F:%L %m%n</pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy interval="1"/> </Policies> </RollingFile> The log files do get renamed daily. But the Javadoc of FileRenameAction class indicates there is an option renameEmptyFiles which is false by default so if a day's log is empty it deletes it instead

问题 I have a logger that send log to a log server storage. This work fine but the patternlayout isn't used. With or without that doesn't change anything.
