log4j配置文件示例

Log4j配置文件实现了输出到控制台、文件、回滚文件、发送日志邮件、输出到数据库日志表、自定义标签等全套功能。

根配置如下

log4j.rootLogger=DEBUG,console,dailyFile,imlog4j.additivity.org.apache=true

---

【1】 控制台(console)

log4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.Threshold=DEBUGlog4j.appender.console.ImmediateFlush=truelog4j.appender.console.Target=System.errlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【2】日志文件(logFile)

log4j.appender.logFile=org.apache.log4j.FileAppenderlog4j.appender.logFile.Threshold=DEBUGlog4j.appender.logFile.ImmediateFlush=truelog4j.appender.logFile.Append=truelog4j.appender.logFile.File=D:/logs/log.log4jlog4j.appender.logFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.logFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【3】回滚文件(rollingFile)

log4j.appender.rollingFile=org.apache.log4j.RollingFileAppenderlog4j.appender.rollingFile.Threshold=DEBUGlog4j.appender.rollingFile.ImmediateFlush=truelog4j.appender.rollingFile.Append=truelog4j.appender.rollingFile.File=D:/logs/log.log4jlog4j.appender.rollingFile.MaxFileSize=200KBlog4j.appender.rollingFile.MaxBackupIndex=50log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.rollingFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【4】定期回滚日志文件(dailyFile)

log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.dailyFile.Threshold=DEBUGlog4j.appender.dailyFile.ImmediateFlush=truelog4j.appender.dailyFile.Append=truelog4j.appender.dailyFile.File=D:/logs/log.log4jlog4j.appender.dailyFile.DatePattern='.'yyyy-MM-ddlog4j.appender.dailyFile.layout=org.apache.log4j.PatternLayoutlog4j.appender.dailyFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【5】应用于socket

log4j.appender.socket=org.apache.log4j.RollingFileAppenderlog4j.appender.socket.RemoteHost=localhostlog4j.appender.socket.Port=5001log4j.appender.socket.LocationInfo=true

---

【6】发送日志到指定邮件

log4j.appender.mail=org.apache.log4j.net.SMTPAppenderlog4j.appender.mail.Threshold=FATALlog4j.appender.mail.BufferSize=10log4j.appender.mail.From = [e-mail]=mail.comlog4j.appender.mail.Subject=Log4J Messagelog4j.appender.mail.To= [e-mail]=org.apache.log4j.PatternLayoutlog4j.appender.mail.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【7】 应用于数据库

log4j.appender.database=org.apache.log4j.jdbc.JDBCAppenderlog4j.appender.database.URL=jdbc:mysql://localhost:3306/testlog4j.appender.database.driver=com.mysql.jdbc.Driverlog4j.appender.database.user=rootlog4j.appender.database.password=log4j.appender.database.sql=INSERT INTO LOG4J (Message) VALUES('=[%-5p] %d(%r) --> [%t] %l: %m %x %n')log4j.appender.database.layout=org.apache.log4j.PatternLayoutlog4j.appender.database.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n

---

【8】自定义Appender

log4j.appender.im = net.cybercorlin.util.logger.appender.IMAppenderlog4j.appender.im.host = mail.cybercorlin.netlog4j.appender.im.username = usernamelog4j.appender.im.password = passwordlog4j.appender.im.recipient = [e-mail]=org.apache.log4j.PatternLayoutlog4j.appender.im.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n
