Spring+MyBatis多数据源配置实现示例

最近用到了MyBatis配置多数据源，原以为简单配置下就行了，实际操作后发现还是要费些事的，这里记录下，以作备忘

不多废话，直接上代码，后面会有简单的实现介绍

jdbc和log4j的配置

#定义输出格式
ConversionPattern=%d %-5p [%t] %c - %m%n

log4j.rootLogger=DEBUG,Console
log4j.logger.com.cnblogs.lzrabbit=DEBUG
log4j.logger.org.springframework=ERROR
log4j.logger.org.mybatis=ERROR
log4j.logger.org.apache.ibatis=ERROR
log4j.logger.org.quartz=ERROR
log4j.logger.org.apache.axis2=ERROR
log4j.logger.org.apache.axiom=ERROR
log4j.logger.org.apache=ERROR
log4j.logger.httpclient=ERROR
#log4j.additivity.org.springframework=false
#Console 
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Threshold=DEBUG 
log4j.appender.Console.Target=System.out 
log4j.appender.Console.layout=org.apache.log4j.PatternLayout 
log4j.appender.Console.layout.ConversionPattern=${ConversionPattern}
#log4j.appender.Console.encoding=UTF-8

#org.apache.log4j.DailyRollingFileAppender
log4j.appender.DailyFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DailyFile.DatePattern='.'yyyy-MM-dd'.log'
log4j.appender.DailyFile.File=${myApp.root}/logs/daily.log
log4j.appender.DailyFile.Append=true
log4j.appender.DailyFile.Threshold=DEBUG
log4j.appender.DailyFile.layout=org.apache.log4j.PatternLayout
log4j.appender.DailyFile.layout.ConversionPattern=${ConversionPattern}
log4j.appender.DailyFile.encoding=UTF-8

# %c 输出日志信息所属的类的全名 
# %d 输出日志时间点的日期或时间，默认格式为ISO8601，也可以在其后指定格式，比如：%d{yyy-MM-dd HH:mm:ss}，输出类似：2002-10-18- 22：10：28
# %f 输出日志信息所属的类的类名 
# %l 输出日志事件的发生位置，即输出日志信息的语句处于它所在的类的第几行 
# %m 输出代码中指定的信息，如log(message)中的message 
# %n 输出一个回车换行符，Windows平台为“rn”，Unix平台为“n” 
# %p 输出优先级，即DEBUG，INFO，WARN，ERROR，FATAL。如果是调用debug()输出的，则为DEBUG，依此类推 
# %r 输出自应用启动到输出该日志信息所耗费的毫秒数 
# %t 输出产生该日志事件的线程名
