四、项目源码

1、db.properties

 db.username=root

 db.password=root

 db.driverClass=com.mysql.jdbc.Driver

 db.jdbcUrl=jdbc:mysql://localhost:3306/ssh_01

 db.initialPoolSize=2

 db.maxPoolSize=20

2、log4j.properties

 # Global logging configuration

 log4j.rootLogger=ERROR, stdout

 # MyBatis logging configuration...

 log4j.logger.org.mybatis.example.BlogMapper=TRACE

 # Console output...

 log4j.appender.stdout=org.apache.log4j.ConsoleAppender

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

 log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

 # Start logging

 log4j.logger.cn.com.zfc.model.UserMapper=TRACE

3、applicationContext.xml（可以把通用的配置抽取出来，便于管理）
