网上看到很多关于Spring与Hibernate的集成的文章,奈何由于那些文章写作时间较早,很多都是Spring 3 和Hibernate 4等较旧的版本。所以我在这里使用更新的版本来说明一下。
添加项目依赖
首先我们需要一个Java Web项目,最好使用Maven或Gradle构建工具,方便我们解决软件依赖。我在这里使用Gradle构建工具,构建脚本如下。我们只要引入spring-webmvc和spring-orm这两个包,其他的Spring依赖会自动由构建工具解决。然后还需要引入数据源、Hibernate、JSTL等依赖项。脚本的最后定义了一个任务用于生成对应的pom文件方便Maven工具使用。

配置web.xml
然后打开WEB-INF/web.xml文件,添加以下内容。

配置Spring
相对应的应该有两个Spring配置文件/WEB-INF/applicationContext.xml和/WEB-INF/dispatcher-servlet.xml。前者是根配置文件,用于配置数据库等后端、全局的组件,后者是MVC配置文件,用于配置MVC和Web相关的组件。
然后在/WEB-INF/applicationContext.xml中,我们配置Hibernate和Spring集成的组件。我们需要配置数据源、HibernateSessionFactory、Hibernate事务管理器、事务连接点、Hibernate模板等Bean,然后在操作数据的时候使用Hibernate模板,就能获得Spring控制的事务管理功能了。

然后来配置一下Spring Web MVC的组件。在dispatcher-servlet.xml中添加以下配置。这里添加了JSP视图解析器和类型转换器,如果不需要自定义类型转换可以将对应片段删掉。

至此,Hibernate与Spring的集成就算配置完了。最后我还写了一个小例子,放在了Github上,有兴趣的同学可以看看。
总结
以上就是本文关于Spring Web MVC和Hibernate的集成配置详解的全部内容,希望对大家有所帮助。感兴趣的朋友可以继续参阅本站其他相关专题,如有不足之处,欢迎留言指出。感谢朋友们对本站的支持!
