log4j使用oracle保存日志信息

为了保存通讯时候产生的保温往来流水记录，使用log4j将流水保存到数据库。

1、数据库表设计如下：

create table COMMUNICATIONLOG  (
   ID                   VARCHAR2(32)                    not null,
   SEQCODE              VARCHAR2(8)                     not null,
   COMMDATE             VARCHAR2(10),
   COMMTIME             VARCHAR2(10),
   TRANCODE             VARCHAR2(6),
   TYPE                 CHAR(1),
   BITMAP               VARCHAR2(100),
   CONTENT              VARCHAR2(2000),
   MAPCONTENT           VARCHAR2(2000),
   constraint PK_COMMUNICATIONLOG primary key (ID)
);

comment on table COMMUNICATIONLOG is
'通讯报文日志流水表';

comment on column COMMUNICATIONLOG.ID is
'ID';

comment on column COMMUNICATIONLOG.SEQCODE is
'流水号';

comment on column COMMUNICATIONLOG.COMMDATE is
'通讯日期';

comment on column COMMUNICATIONLOG.COMMTIME is
'通讯时间';

comment on column COMMUNICATIONLOG.TRANCODE is
'当期交易号';

comment on column COMMUNICATIONLOG.TYPE is
'报文类型（R:来帐；S：往帐）';

comment on column COMMUNICATIONLOG.BITMAP is
'位元图内容';

comment on column COMMUNICATIONLOG.CONTENT is
'报文内容';

comment on column COMMUNICATIONLOG.MAPCONTENT is
'MAP内容';

 

2、log4j.properties文件中的配置定义如下：

 

log4j.logger.com.jbsoft.communication=DEBUG, LOGDB2

log4j.appender.LOGDB2=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.LOGDB2.Driver=oracle.jdbc.driver.OracleDriver
log4j.appender.LOGDB2.URL=jdbc:oracle:thin:@localhost:1521:orcl
log4j.appender.LOGDB2.user=jsloan
log4j.appender.LOGDB2.password=jadebird
log4j.appender.LOGDB2.sql=insert into COMMUNICATIONLOG (ID,SEQCODE,COMMTIME,TRANCODE,COMMDATE,CONTENT,BITMAP,TYPE,MAPCONTENT) values (S_COMMUNICATIONLOG.Nextval,'%X{seqcode}','%d{HH:mm:ss}','%X{trancode}','%d{yyyy-MM-dd}','%X{content}','%X{bitMap}','%X{type}','%X{map}')  
log4j.appender.LOGDB2.layout=org.apache.log4j.PatternLayout

 

 

3、使用AOP方式的程序使用

package com.jbsoft.communication.proxy.impl;

import org.aopalliance.intercept.MethodInvocation;
import org.apache.commons.lang.ArrayUtils;
import org.apache.log4j.MDC;

import com.jbsoft.communication.entity.message.BuildData;
import com.jbsoft.communication.entity.message.Message8583;
import com.jbsoft.communication.proxy.AbstractInterceptor;
import com.jbsoft.communication.util.EncodingUtils;

/**
 * 创建拦截器实现类
 * <p></p>
 * @author liubing
 * Date 2010-1-22
 */
public class BuilderInterceptorImpl extends AbstractInterceptor {
	
	public BuilderInterceptorImpl() {
		super( BuilderInterceptorImpl.class );
	}

	@Override
	public Object invoke( MethodInvocation invocation ) throws Throwable {
		System.out.println(  "****" +  Thread.currentThread().getId() );
		StringBuffer buffer = new StringBuffer( "\r\n" );
		buffer.append( "=======================================================\r\n" );
		Object[] args = invocation.getArguments();
		BuildData buildData = ( BuildData ) args[ 0 ];
		String seqCode = buildData.getMap().get( "seqcode" );
		buffer.append( "当前需要进行报文转换的Map对象内容为：" 
				+ buildData.getMap().toString() );
		buffer.append( "\r\n==================================================\r\n" );
		Message8583 result = ( Message8583 ) invocation.proceed();
		buffer.append( "当前往帐报文元位图为：" + ArrayUtils.toString( result.getBitmap() ) );
		buffer.append( "\r\n当前往帐报文内容为：" + EncodingUtils.exchangeGB2312( result.getContent() ) );
		buffer.append( "\r\n==================================================\r\n" );
		MDC.put( "trancode", buildData.getTranCode() );
		MDC.put( "seqcode", seqCode );
		MDC.put( "content", EncodingUtils.exchangeGB2312( result.getContent() ) );
		MDC.put( "bitMap", ArrayUtils.toString( result.getBitmap() ) );
		MDC.put( "type", "S" );
		MDC.put( "map", buildData.getMap().toString() );
		getLog().debug( buffer.toString() );
		return result;
	}

}

 

MDC是apache.log4j提供的，用于保存日志信息的上下文参数，其实现相当于一个MAP。保存在MDC中的内容在log4j.properties中的使用方式为：

%X{Key}

  例如：

%X{trancode}

 就是获取MDC中key为trancode的值。

注意：由于这里定义了使用数据库方式处理日志，因此每次调用Logger的debug/info/warn/error/fatal方法时，都会记录到数据库，为了保证不记录多余的信息，这里只调用一次getLog().debug()方法。环绕通知的实现，请参阅Spring文档。
