Spring整合Struts2

Spring整合Struts21整合目的:让Spring的IOC容器去管理Struts2的Action, 2Struts2是web开源框架,Spring要整合Struts2,也就是说要在web应用使用Spring①. 需要额外加入的 jar 包:spring-web-4.0.0.RELEASE.jarspring-webmvc-4.0.0.RELEASE.jar ②. Spring 的配置文件, 和非 WEB 环境没有什么不同 ③. 需要在 web.xml 文件中加入如下配置: <!-- 配置

Spring整合hibernate4：事务管理

Spring和Hibernate整合后,通过Hibernate API进行数据库操作时发现每次都要opensession,close,beginTransaction,commit,这些都是重复的工作,我们可以把事务管理部分交给spring框架完成. 配置事务(xml方式) 使用spring管理事务后在dao中不再需要调用beginTransaction和commit,也不需要调用session.close(),使用API  sessionFactory.getCurrentSession()来

8 -- 深入使用Spring -- 7...2 MVC框架与Spring整合的思考

8.7.2 MVC 框架与Spring整合的思考 对于一个基于B/S架构的JAVA EE 应用而言,用户请求总是向MVC框架的控制器请求,而当控制器拦截到用户请求后,必须调用业务逻辑组件来处理用户请求.此时有一个问题:控制器应该如何获得业务逻辑组件? 最容易想到的策略是,直接通过new 关键字创建业务逻辑组件,然后调用业务逻辑组件的方法,根据业务逻辑方法的返回值确定结果. 在实际的应用中,很少见到采用上面的访问策略,因为这是一种非常差的策略.不这样做至少有如下三个原因: ⊙ 控制器直接创建业务逻

MyBatis Spring整合配置映射接口类与映射xml文件

Spring整合MyBatis使用到了mybatis-spring,在配置mybatis映射文件的时候,一般会使用MapperScannerConfigurer,MapperScannerConfigurer会自动扫描basePackage指定的包,找到映射接口类和映射XML文件,并进行注入.配置如下: [html] view plain copy <!-- 数据源 --> <bean id="dataSource" class="com.mchange.v
