利用log4mongo-java+mongodb复制集搭建java日志系统

转至出处：http://blog.csdn.net/jaysuper/article/details/8060347

可以将log4j的日志文件写入到mongodb中，原文方法如下

1. Download and install MongoDB from http://www.mongodb.org/downloads  
2. Start mongod running on localhost on the default port
3. Download the Mongo Java driver jarfile
4. Download Log4J jarfile
5. Download log4mongo-java jarfile
6. Place these three jar files in your classpath
7. Create a file called log4j.properties in your classpath
8. Add the following lines to the log4j.properties file
   1.  like：
   2.    
   3. log4j.rootLogger=debug, stdout, R, MongoDB
   4.  
   5. log4j.appender.stdout=org.apache.log4j.ConsoleAppender
   6. log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
   7. log4j.appender.stdout.layout.ConversionPattern=%-d{MM-dd HH:mm:ss.SSS} %-5p - [%c{1}.%t] %m%n
   8.  
   9. log4j.appender.R=org.apache.log4j.RollingFileAppender
   10. log4j.appender.R.File=logs/client.log
   11. log4j.appender.R.MaxFileSize=1000KB
   12. log4j.appender.R.MaxBackupIndex=1
   13. log4j.appender.R.layout=org.apache.log4j.PatternLayout
   14. log4j.appender.R.layout.ConversionPattern=%-d{MM-dd HH:mm:ss.SSS} %-5p - [%c{1}.%t] %m%n
   15.  
   16. log4j.appender.MongoDB=org.log4mongo.MongoDbAppender
   17. log4j.appender.MongoDB.databaseName=test
   18. log4j.appender.MongoDB.collectionName=log
   19. log4j.appender.MongoDB.hostname=192.168.57.128 
   20. log4j.appender.MongoDB.port=27017
9. Create a Java Test class like:
10. public class logSystem {
12. private final static Logger logger = LoggerFactory.getLogger(logSystem.class);
13.     public static void main( String[] args )
14.     {
15.         try {
16.         throw new Exception();
17. } catch (Exception e) {
18. logger.debug("测试将日记同步到mongodb", e);
19. }
20.     }
21. }
