SSM框架整合开发的文件配置

1.SSM开发所需的包

Spring框架jar包

spring-framework-4.x.x.RELEASE文件夹下libs目录下所有模块的jar包和Spring的核心容器必须依赖的common-logging的jar包

Mybatis框架jar包，共计21个

mybatis-3.x.x.jar和mybatis-3.x.x文件夹下的lib目录下的所有jar包，共计13个

MyBatis整合Spring中间件jar包

在Mybatis文件里面的mybatis-spring-x.jar类似的包，用于满足Mybatis用户整合Spring的需求。中间件有两个作用：

   1.在Spring中配置Mybatis工厂类

   2.在DAO层使用Spring注入的工具bean对数据进行操作

Spring的APO事务jar包

aspectj框架的jar包

aspectjt.jar、aspectjtools.jar、aspectjweaver.jar、org.aspectjmatcher.jar

aop联盟的jar包

aopaliance.jar

数据库驱动jar包

mysql-connector-java-x.x.x.jar

数据源c3p0所需jar包

c3p0-x.x.x.jar、hibernate-c3p0-x.x.x.Final.jar、mchange-commons-java.x.x.x.jar

JSTL标签库jar包

javax.servlet.jsp.jstl-x.x.x.jar、java.servlet.jsp.jstl-api-x.x.x.jar

2.数据库属性文件db.properties

dataSource.driverClass = com.mysql.jdbc.Driver
dataSource.jdbcUrl = jdbc:mysql://localhost:3306/mydatabase
dataSource.user = root
dataSource.password = chengxi
dataSource.maxPoolSize = 20
dataSource.maxIdleTime = 1000
dataSource.minPoolSize = 6
dataSource.initialPoolSize = 5

3.log4j配置文件:log4j.properties

# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.org.blog.dao.GuitarMapper=DEBUG
# 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
