篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了eclipse通过maven建立java se工程配置log4j,打包成zip,将jar包和配置文件分开,并以bat和sh文件启动java程序相关的知识,希望对你有一定的参考价值。
一.新建maven的java工程
1.eclipse里file-new-other,选择maven Project
2.选中 Use default Workspace location,然后 next
3.选择maven-archetype-quitstart,然后next
4.填入工程信息,然后finish
6.新建好的工程结构如图
7.将test下和java下自动生成的java类删除,右键build-path选择好jdk版本,整个工程就建好了。
二.配置log4j
1.将工程目录调整成下图(这步其实是为下面maven打包做准备)
2.通过maven导入log4j,jar
在pom.xml的<dependencies>里加入以下语句
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.0</version> </dependency>
3.在src/conf下面新建文件log4j.properties,内容如下:
### 设置### log4j.rootLogger = debug,stdout,D,E ### 输出信息到控制台### 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{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n ### 输出debug级别以上的日志到E://logs/log.log ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = E://logs/log.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n ### 输出error级别以上的日志到E://logs/error.log ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File =E://logs/error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
4.新建日志测试类,内容如下:
package com.zhuzhixi.zhuzhixiDataMaker.Test; import org.apache.log4j.Logger; public class LogTest { private static Logger logger = Logger.getLogger(LogTest.class); public static void main(String[] args) { // TODO Auto-generated method stub // 记录debug级别的信息 logger.debug("This is debug message."); // 记录info级别的信息 logger.info("This is info message."); // 记录error级别的信息 logger.error("This is error message."); } }
5.结果如下:
5.1在控制台打出如下信息
5.2在e盘的logs文件夹下出现两个文件
内容分别如下:
三.配置maven-assembly-plugin并打包
1.在pon.xml里面更改为下面的内容(工程项目的文件结构在上面)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.zhuzhixi</groupId> <artifactId>zhuzhixiDataMaker</artifactId> <packaging>jar</packaging> <version>0.0.1-SNAPSHOT</version> <description></description> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <!-- log4j日志 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.0</version> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/conf</directory> </resource> <resource> <directory>src/main/resources</directory> </resource> </resources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.7</version> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <version>2.5.5</version> <configuration> <encoding>UTF-8</encoding> <appendAssemblyId>false</appendAssemblyId> <descriptors> <descriptor>src/main/assemble/package.xml</descriptor> </descriptors> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.3</version> <configuration> <source>1.8</source> <target>1.8</target> <verbose>true</verbose> </configuration> </plugin> </plugins> </build> </project>
2.src/main/assemble目录下的package.xml内容为:
<assembly xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/assembly-1.0.0.xsd"> <id>package</id> <formats> <format>zip</format> </formats> <includeBaseDirectory>true</includeBaseDirectory> <fileSets> <fileSet> <directory>src/main/bin</directory> <outputDirectory>bin</outputDirectory> </fileSet> <fileSet> <directory>src/main/conf</directory> <outputDirectory>conf</outputDirectory> </fileSet> <fileSet> <directory>src/main/logs</directory> <outputDirectory>logs</outputDirectory> </fileSet> <fileSet> <directory>src/main/work</directory> <outputDirectory>work</outputDirectory> </fileSet> </fileSets> <dependencySets> <dependencySet> <outputDirectory>lib</outputDirectory> <scope>runtime</scope> </dependencySet> </dependencySets> </assembly>
3.在src/main/bin下面新建文件start.bat和start.sh两个文件,用于windows和linux里启动java程序
start.bat的内容如下:
@echo off SET base=%~dp0 SET main_class="com.zhuzhixi.zhuzhixiDataMaker.Test.LogTest" SET conf=%base%..\\conf SET libs=%base%..\\lib SET class_path=%conf%;%libs%\\*; java -classpath %class_path% %main_class% @pause
start.sh的内容如下:
#!/bin/bash script_path=$(cd "$(dirname "$0")"; pwd) lib_path=${script_path}/../lib main_class="com.zhuzhixi.zhuzhixiDataMaker.Test.LogTest" conf_path=${script_path}/../etc/conf CLASSPATH="${conf_path}" for jar in $lib_path/*.jar do if [ "$CLASSPATH" = "" ] ; then CLASSPATH=$jar else CLASSPATH=$CLASSPATH:$jar fi done export CLASSPATH=$CLASSPATH echo "java ${main_class} \\"$@\\""
4.右键工程-Debug As-maven assembly:assembly
输出日志如下图则打包成功。
四.测试
1.解压zip文件,文件夹结构如下,所有文件均存在:
2.进入bin,运行start.bat(运行环境需要安装jre环境)
3.结果如下:
在e盘的logs文件夹下
log.log内容如下:
error.log内容如下
因此,conf的log4j.properties正确被读取了。
五.将log4j的日志位置设为动态,即打包后的文件夹里的logs文件夹
1.将log4j.properties改为一下内容,(将日志位置用${log4j.home}代替)
### \\u8BBE\\u7F6E### log4j.rootLogger = debug,stdout,D,E ### 设置 ### 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{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n ### 设置debug级别以上的日志到logs/error.log ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ${log4j.home}/log.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n ### 设置error级别以上的日志到logs/error.log ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File =${log4j.home}/error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
2.主类不再是LogTest.java ,新建一个类LogTestMain.java,内容如下:
package com.zhuzhixi.zhuzhixiDataMaker.Test; import org.apache.log4j.Logger; public class LogTestMain { public static void main(String[] args) { // TODO Auto-generated method stub String binPath=System.getProperty("user.dir") ; System.out.println(binPath+"\\\\..\\\\logs"); System.setProperty("log4j.home", binPath+"\\\\..\\\\logs"); String log4jHome=System.getProperty("log4j.home"); System.out.println(log4jHome); new LogTest().testLog(); } }
2.将LogTest.java的内容改成下面:
package com.zhuzhixi.zhuzhixiDataMaker.Test; import org.apache.log4j.Logger; public class LogTest { private static Logger logger = Logger.getLogger(LogTest.class); public void testLog(){ // 记录debug级别的信息 logger.debug("This is debug message."); // 记录info级别的信息 logger.info("This is info message."); // 记录error级别的信息 logger.error("This is error message."); } }
3.然后更改start.bat的main_class为com.zhuzhixi.zhuzhixiDataMaker.Test.LogTestMain
@echo off SET base=%~dp0 SET main_class="com.zhuzhixi.zhuzhixiDataMaker.Test.LogTestMain" SET conf=%base%..\\conf SET libs=%base%..\\lib SET class_path=%conf%;%libs%\\*; java -classpath %class_path% %main_class% @pause
4.此时再打包后运行start.bat,日志文件就会在打包后的logs文件夹里了。
注意:一定要在执行Logger.getLogger(LogTestMain.class);之前执行System.getProperty("log4j.home");,所以主类不能使用log打印日志
