关于log4j在SSH中输出日志的配置

（一）.首先配置好SSH jar包

（二）.在web.xml中配置监听器：

 <!-- 加载log4j配置文件 -->
	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>classpath:config/log/log4j_config.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>

?(三).定义日志log4j_config.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "file:///D:\soft\log4j\log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<appender name="dailyFile" class="org.apache.log4j.DailyRollingFileAppender">
	<param name="File" value="c:\\logs\\log.log"/>
	<param name="Append" value="true"/>
	<param name="Encoding" value="UTF-8"/>
	<layout class="org.apache.log4j.PatternLayout">
		<param name="ConversionPattern" value="%-6p%d{yyyy-MM-dd HH:mm}[%t]-%m%n"/>
	</layout>
</appender>
 <logger name="org.springframework">
	<level value="INFO"/>
	<appender-ref ref="dailyFile"/>
</logger>
<logger name="org.hibernate">
	<level value="INFO"/>
	<appender-ref ref="dailyFile"/>
</logger>
<logger name="org.apache">
	<level value="INFO"/>
	<appender-ref ref="dailyFile"/>
</logger>
<logger name="com.opensymphony">
	<level value="INFO"/>
	<appender-ref ref="dailyFile"/>
</logger> 
<logger name="com.mchange">
	<level value="INFO"/>
	<appender-ref ref="dailyFile"/>
</logger> 
<root>
	<priority value="INFO"/>
	<appender-ref ref="dailyFile"/>
</root>
</log4j:configuration>

?(四).日志输出到C:\logs\log.log文件中

?(五).有可能加载log4j.dtd文件

?(六).配置logAdvice.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	   xmlns:tx="http://www.springframework.org/schema/tx"
	   xmlns:aop="http://www.springframework.org/schema/aop"
	   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
	   http://www.springframework.org/schema/tx http://www.springframework.org/tx/spring-tx-3.0.xsd
	   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
	   http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd">
		
	   <bean id="logAfter" class="com.newsicom.jxc.common.aop.log.LogAfterAdvice"	/>
	   <bean id="logBefore" class="com.newsicom.jxc.common.aop.log.LogBeforeAdvice" />
	   <bean id="logThrow" class="com.newsicom.jxc.common.aop.log.LogThrowAdvice" />
	   
	   <aop:config>
	   			<aop:pointcut id="serviceOperation-logAfter" expression="execution(* com.newsicom.jxc.basicinfo.goodsunits.service..*.*(..))" />
	   			<aop:advisor pointcut-ref="serviceOperation-logAfter" advice-ref="logAfter" />
	   </aop:config>
	
	   <aop:config>
	           <aop:pointcut id="serviceOperation-logBefore" expression="execution(* com.newsicom.jxc.basicinfo.goodsunits.service..*.*(..))"/>
		       <aop:advisor pointcut-ref="serviceOperation-logBefore" advice-ref="logBefore"  /> 
	   </aop:config>
	
	   <aop:config>
		      	<aop:pointcut id="serviceOperation-logThrow" expression="execution(* com.newsicom.jxc.basicinfo.goodsunits.service..*.*(..))"/>
				<aop:advisor pointcut-ref="serviceOperation-logThrow" advice-ref="logThrow"  /> 
	   </aop:config> 	   
</beans>

?（七）.编写Advice:

 LogAfterAdvice

/**
 * LogAfterAdvice
 */
package com.newsicom.jxc.common.aop.log;

import java.lang.reflect.Method;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.springframework.aop.AfterReturningAdvice;

public class LogAfterAdvice implements AfterReturningAdvice{

	private static final Logger log=Logger.getLogger(LogAfterAdvice.class);

	
	public void afterReturning(Object returnValue, Method method, Object[] args,
			Object target) throws Throwable {
		log.log(Level.INFO, target.getClass().getName()+"调用"+method.getName()+"结束，返回值："+returnValue+"---");
	}
}

?? LogBeforeAdvice：

package com.newsicom.jxc.common.aop.log;

import java.lang.reflect.Method;

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.springframework.aop.MethodBeforeAdvice;

public class LogBeforeAdvice implements MethodBeforeAdvice {

	private static final Logger log=Logger.getLogger(LogBeforeAdvice.class);
	public void before(Method method, Object[] args, Object target)
			throws Throwable {
		log.log(Level.INFO, target.getClass().getName()+"调用"+method.getName()+"开始---");
	}
}

?LogThrowAdvice：

package com.newsicom.jxc.common.aop.log;
import java.lang.reflect.Method;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.springframework.aop.ThrowsAdvice;

import com.newsicom.jxc.common.util.GeneralUtil;
/**
 * @author 
 * 
 */
public class LogThrowAdvice implements ThrowsAdvice {

	private static final Logger log = Logger.getLogger(LogThrowAdvice.class);

	public void afterThrowing(Method method, Object[] args, Object target,
			Throwable throwable) {
		log.log(Level.ERROR,
				target.getClass().getName() + "调用" + method.getName()
						+ "时有异常抛出：" + GeneralUtil.getTrace(throwable) + "---");
	}
}

?(八).在applicationContext.xml中添加logAdvice.xml

<!-- Aop日志追踪 -->
	<aop:aspectj-autoproxy proxy-target-class="true" />
	<import resource="classpath:config/log/logAdvice.xml" />

? (九).辅助类：

package com.newsicom.jxc.common.constant;
public final class CommonConstant {

	public final static String EMPTY_STRING = "";
}

/*

	}

	}

	}
