spring,springmvc,mybatis整合redis，redis作为缓存使用

环境

1，windows7

2，mysql

3，eclipse

4，redis

5，tomcat7

注意：启动redis的方式，已经把redis做成windows服务，以windows服务的方式启动

把redis做成windows服务的命令行

redis-server --service-install redis.windows.conf

可自行百度其他命令行

项目整合经过测试，可以正常启动，redis缓存和mysql操作均没有问题

情景：使用spring,springmvc,mybatis整合redis

目录结构如下：

报错是因为eclipse抽风，不用管。

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

log4j.appender.error.append=true
#log4j.appender.error.File=${webapp.root}/logs/error.log
log4j.appender.error.File=E:/webssmLogs/logs/error.log

注意：配置中有log4j.appender.error=org.apache.log4j.DailyRollingFileAppender，

也可以使用代码中的log4j包下的类来实现，效果是一样的。
