  • spring之SSH整合

    下面我们分为五步:

    1、导入所需要的pom依赖

    2、几大框架的配置文件(web.xml/struts.xml、hibernate的配置、spring的配置)

    3、spring与hibernate整合桥接的配置文件替换掉了hibernate.cfg.xml
      spring-hibernate.xml(难点)
      注册数据库连接信息文件
      配置数据库连接池(新的知识点)
      配置sessionfactory
      配置声明式事务(aop)
        com.huang.base.xxxBiz
        com.huang.book.xxxBiz
        com.huang.book.yyyBiz
        com.huang.*.*Biz

        配置Base模块

        UserDao
        private Session session;

        add
        session
        edit
        del

       <bean id="sesion" class="....">

      <bean id="userDao" class="com.huang.dao.UserDao">
      <property name="session' ref="session"></property>
      </bean>

    数据库相关

    db.username=root
    db.password=root
    db.driverClass=com.mysql.jdbc.Driver
    db.jdbcUrl=jdbc:mysql://127.0.0.1:3306/db_book?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
