Maven项目添加log4j配置

1. pom.xml添加:

   <properties>
        <spring.version>3.2.5.RELEASE</spring.version>
    </properties>

 

<dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-web</artifactId>
                <version>${spring.version}</version>
        </dependency>
        <dependency>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
                <version>1.1.3</version>
            </dependency>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.14</version>
            <type>jar</type>
            <scope>compile</scope>
        </dependency>

 

2. web.xml添加:

  <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>WEB-INF/log4j.properties</param-value>
    </context-param>
    <context-param>
        <param-name>log4jRefreshInterval</param-name>
        <param-value>3000</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

3. 在web.xml同路径下创建log4j.properties文件,内容如下:

#Global configuration
log4j.rootLogger = INFO, stdout, logfile

log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %5p [%t] - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=/var/banktansWeb/logs/banktansWeb.log
log4j.appender.logfile.MaxFileSize=30MB
log4j.appender.logfile.MaxBackupIndex=100
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - <%m>%n

#Spring config
log4j.logger.org.springframewaork = DEBUG
log4j.logger.org.springframework.ws.client.MessageTracing.sent=TRACE
log4j.logger.org.springframework.ws.client.MessageTracing.received=DEBUG
log4j.logger.org.springframework.ws.server.MessageTracing=DEBUG

#http config
log4j.logger.org.apache.commons.httpclient = DEBUG
log4j.logger.httpclient.wire.header = DEBUG
log4j.logger.httpclient.wire.content = DEBUG

#Mybatis config
log4j.logger.net.openwares.test.mapper = TRACE

 

注:log4j.appender.logfile.File是log存放路径,自己创建配置替换.

4. 代码引入.

/**
     * 系统日志记录文件
     */
private static Log LOGGER = LogFactory.getLog(类名.class);

LOGGER.info(this.getClass().getName() + "有一连接关闭！当前链接数为"+ getOnlineCount());

LOGGER.info("有新连接加入！当前链接数为" + getOnlineCount());
