　　xwork-core-2.3.20.jar

　　③Hibernate：

　　antlr-2.7.7.jar
　　dom4j-1.6.1.jar
　　hibernate-commons-annotations-4.0.5.Final.jar
　　hibernate-core-4.3.11.Final.jar
　　hibernate-jpa-2.1-api-1.0.0.Final.jar

　　jboss-logging-3.1.3.GA.jar
　　jboss-logging-annotations-1.2.0.Beta1.jar
　　jboss-transaction-api_1.2_spec-1.0.0.Final.jar

　　④C3P0：

　　c3p0-0.9.5.1.jar
　　mchange-commons-java-0.2.10.jar
　　mysql-connector-java-5.1.8-bin.jar

　　⑤JSTL：

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）
