log4j 数据库模式，密码以代码形式

正常配置：

log4j.appender.db=org.apache.log4j.jdbc.JDBCAppender

log4j.appender.db.BufferSize=1

#log4j.appender.db.sqlname=dbo

log4j.appender.db.driver=oracle.jdbc.driver.OracleDriver

log4j.appender.db.URL=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:xxx

log4j.appender.db.user=xxx

log4j.appender.db.password=xxx

log4j.appender.db.sql=insert into Sys_Log (Log_Belong_Biz,Log_Belong_Object,Log_Belong_Action,Log_Subject,Log_Detail,Input_User,Input_DateTime) VALUES ('%X{logBelongBiz}','%X{logBelongObject}','%X{logBelongAction}','%X{logSubject}','%X{logDetail}','%X{inputUser}',to_date(substr('%d',0,19),'yyyy-MM-dd hh24:mi:ss'))

log4j.appender.db.layout=org.apache.log4j.PatternLayout

重写JDBCAppend:

log4j.appender.db=Log4jJDBCAppender

log4j.appender.db.BufferSize=1

#log4j.appender.db.sqlname=dbo

log4j.appender.db.sql=insert into Sys_Log (Log_Belong_Biz,Log_Belong_Object,Log_Belong_Action,Log_Subject,Log_Detail,Input_User,Input_DateTime) VALUES ('%X{logBelongBiz}','%X{logBelongObject}','%X{logBelongAction}','%X{logSubject}','%X{logDetail}','%X{inputUser}',to_date(substr('%d',0,19),'yyyy-MM-dd hh24:mi:ss'))

log4j.appender.db.layout=org.apache.log4j.PatternLayout

public class Log4jJDBCAppender extends JDBCAppender {

public final static String USER = ConfigUtility.getConfigValue("/config.properties", "DB_USERNAME");

public final static String PASS = JdbcUtility.getPassword();

public final static String DB_URL = ConfigUtility.getConfigValue("/config.properties", "DB_URL");

public Log4jJDBCAppender(){

databaseURL = DB_URL;

databaseUser = USER;

databasePassword=PASS;

}

}
