搭建springmvc+hibernate+sping 框架
-
首先需要的jar报导入到项目中；
-
配置文件；spring配置文件在web.xml里面要引入，项目启动初始化spring的控制器，spingbean的注入, <!-- Controller方法调用规则定义 --><!-- 页面View层基本信息设定 --><!-- servlet映射列表,所有控制层Controller的servlet在这里定义 -->

Hibernate的配置主要有！！！！：
要扫描的包（hibernate注解）；
数据源；sessionFactory；
hibernateTemplate；
配置事物（获取数据不启动事务）
注2：
<!-- 引入属性文件 -->
<context:property-placeholder location="classpath:dbconfig.properties" />
这样获取值${jdbc.url.jeecg}
db.properties内容
hibernate.dialect=org.hibernate.dialect.MySQLDialect
validationQuery.sqlserver=SELECT 1
jdbc.url.jeecg=jdbc:mysql://localhost:3306/projectdb?useUnicode=true&characterEncoding=UTF-8
jdbc.username.jeecg=root
jdbc.password.jeecg=xlj123
jdbc.dbType=mysql
注3：
<!-- 配置事物管理器，在*ServiceImpl里写@Transactional就可以启用事物管理，在查找的方法加上 read-only只读，@Transactional(readOnly=true,propagation=Propagation.NOT_SUPPORTED)//查询不需要开事务-->
