spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现
Spring整合Hibernate有什么好处?
1、由IOC容器来管理Hibernate的SessionFactory
2、让Hibernate使用上Spring的声明式事务
xml:
那什么我们先创建一个账户,再把jar包导一下:
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.3</version> <scope>test</scope> </dependency> <!--jta的jar包--> <dependency> <groupId>javax.transaction</groupId> <artifactId>jta</artifactId> <version>1.1</version> </dependency> <!--mysql数据库驱动--> <dependency> <groupId>org.wisdom-framework</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34_1</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.0.6.Final</version> </dependency> <!--c3p0--> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!--AOP的相关jar--> <dependency> <groupId> org.aspectj</groupId > <artifactId> aspectjweaver</artifactId > <version> 1.8.7</version > </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.2.0.RELEASE</version> </dependency> <!--Spring-ORM--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version> 4.2.2.RELEASE</version> </dependency> </dependencies>Stock:
