[1]Eclipse Mars.2
[2]JDK 1.7
[3]slf4j-log4j12 1.7.2
[4]junit 4.11

 

Introduction

    这里记下免得每次为web app配log4j又得摸索一遍。

 

第一步:pom.xml

<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.nuoke</groupId>  <artifactId>icbc_gbk</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>icbc_gbk Maven Webapp</name>  <url>http://maven.apache.org</url>    <properties>  <project.build.sourceEncoding>GBK</project.build.sourceEncoding><project.reporting.outputEncoding>GBK</project.reporting.outputEncoding>    <spring.version>3.1.2.RELEASE</spring.version>    <cxf.version>3.0.9</cxf.version>    <junit.version>4.11</junit.version>     </properties>     <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>${junit.version}</version>      <scope>test</scope>    </dependency>        <dependency>   <groupId>org.slf4j</groupId>   <artifactId>slf4j-log4j12</artifactId>   <version>1.7.2</version></dependency>        <dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency>    <dependency>  <groupId>org.apache.cxf</groupId>      <artifactId>cxf-rt-frontend-jaxws</artifactId>      <version>${cxf.version}</version>         </dependency>    <dependency>      <groupId>org.apache.cxf</groupId>      <artifactId>cxf-rt-transports-http</artifactId>      <version>${cxf.version}</version>    </dependency>        <dependency>    <groupId>commons-io</groupId>    <artifactId>commons-io</artifactId>    <version>2.4</version></dependency>  </dependencies>  <build>    <finalName>icbc_gbk</finalName>      <plugins>              <plugin>                  <groupId>org.apache.maven.plugins</groupId>                  <artifactId>maven-compiler-plugin</artifactId>                <version>3.0</version>                <configuration>                      <source>1.7</source>                      <target>1.7</target>                      <encoding>GBK</encoding>                  </configuration>              </plugin>        </plugins>    </build></project>

 
第二步：web.xml

<?xml version="1.0" encoding="GBK"?>  <web-app  version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">  <display-name>ICBC</display-name><!-- Log4j--><context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j.xml</param-value></context-param><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><!-- CXF --><servlet><description>Apache CXF Endpoint</description><display-name>cxf</display-name><servlet-name>cxf</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>cxf</servlet-name><url-pattern>/*</url-pattern></servlet-mapping></web-app>

 

 

第三步：log4j.xml

放在[Project Explorer]->[...]->[Java Resources]
->[src/main/resources]节点下面

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"><log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'><appender name="appendConsole" class="org.apache.log4j.ConsoleAppender"><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss:SSS} %l %m%n" /></layout><!--限制输出级别 --><filter class="org.apache.log4j.varia.LevelRangeFilter"><param name="LevelMax" value="FATAL" /><param name="LevelMin" value="DEBUG" /></filter></appender><appender name="myFile" class="org.apache.log4j.RollingFileAppender">                  <param name="File" value="/log/escortcashbox.log" /><!-- 设置日志输出文件名 -->               <!-- 设置是否在重新启动服务时，在原有日志的基础添加新日志 -->               <param name="Append" value="true" />               <param name="MaxBackupIndex" value="10" />               <layout class="org.apache.log4j.PatternLayout">                   <param name="ConversionPattern" value="%p (%c:%L)- %m%n" />               </layout>       </appender><logger name="org.springframework">   <level value="warn" />   <appender-ref ref="appendConsole"/>  </logger><root><priority value="debug" /><appender-ref ref="appendConsole" /><appender-ref ref="myFile"/></root></log4j:configuration>

 

第三步：junit测试
在...[src/test/java]节点下面

package com.nuoke.test;import org.junit.Test;import org.slf4j.Logger;  import org.slf4j.LoggerFactory;  public class MyTest {@Testpublic void TestSlf4j(){//junit app默认会从classes路径下找log4j.xml//为了让web app用同一个log4j.xml文件//web app的 web.xml里指定log4j.xml位置也在classes路径下。    Logger logger = LoggerFactory.getLogger(MyTest.class);      logger.info("Hello World");      int a = 1000;    String b = "test";    logger.debug("a = {}. b = {}.", a, b);  }// end function}//end class
