Spring4与Hibernate4整合配置

xiaoxiao2021-02-28  6

整合关键点

hibernate对象交给Spring创建

1.Hibernate的SessionFactory对象交给Spring创建 2.Hibernate事务交给spring声明式事务管理。

SSH整合: SessionFactory:启动的时候初始化,整个应用都有效;因此创建的工作,交给spring管理。

加载hibernate配置文件去整合

用的是spring4+hibernate4的jar包,但是总是失败,unwrap javax.sql.dataSource

连接池方式

将datasource直接在bean.xml中配置,然后sessionFactory直接使用,这种方式成功了。 记录配置文件如下

bean.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="deptDao" class="cn.itcast.dao.DeptDao"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- service --> <bean id="deptService" class="cn.itcast.service.DeptService"> <property name="deptDao" ref="deptDao"></property> </bean> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.cj.jdbc.Driver"></property> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?characterEncoding=utf8&useSSL=false"></property> <property name="user" value="root"></property> <property name="password" value="qqaazz"></property> <property name="initialPoolSize" value="3"></property> <property name="maxPoolSize" value="10"></property> <property name="maxStatements" value="100"></property> <property name="acquireIncrement" value="2"></property> </bean> <!-- Spring与Hibernate整合 --> <!-- 连接池交给spring管理 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> <property name="dataSource" ref="dataSource"></property> </bean> <!--配置事务管理器类 --> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 配置事务增强(拦截到方法之后,如何管理事务?只读?只写等) --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="*" read-only="false"/> </tx:attributes> </tx:advice> <!--aop配置 --> <aop:config> <aop:pointcut expression="execution(* cn.itcast.service.*.*(..))" id="pt"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/> </aop:config> </beans>

hibernate.cfg.xml文件

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property> <!--常用配置 --> <property name="show_sql">true</property> <property name="format_sql">true</property> <property name="hbm2ddl.auto">update</property> <mapping resource="cn/itcast/entity/Dept.hbm.xml"/> </session-factory> </hibernate-configuration>

测试:

public class App { private ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml"); @Test public void testApp() throws Exception{ DeptService deptService=(DeptService)ac.getBean("deptService"); deptService.save(new Dept(30,"xiaom")); } }
