Hessian RPC-RMI技术 整合Structs Spring Hibernate Ibatis

1、Hessian RPC接口.若需更换版本，请注意与Spring版本兼容。本次案例版本Hessian-3.1.6、Spring 3.2 包hessian-3.1.6.jar 2、服务器端配置(集成项目Spring管理) 1).提供接口Interface IHessianUserService 2).接口实现HessianUserServiceImpl 方法内使用ApplicationContext ctx = ContextLoaderListener.getCurrentWebApplicationContext(); IUserBeanInfo i= (IUserBeanInfo)ctx.getBean("userService"); 调用Spring注入Service，执行后台方法 或者 通过Spring注入 private IUserBeanInfo userService; public IUserBeanInfo getUserService() { return userService; } @Resource public void setUserService(IUserBeanInfo userService) { this.userService = userService; } 3).配置Web.xml监听，使用Spring代理 <servlet> <servlet-name>remote</servlet-name> <!-- 使用Spring的代理Servlet --> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>namespace</param-name> <!-- 配置发布Hessian服务，注意路径及名称(去掉.xml) --> <param-value>config/base/remote-servlet</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>remote</servlet-name> <!--发布Hessian服务URL--> <url-pattern>/remote/*</url-pattern> </servlet-mapping> 4).配置发布Hessian XML remote-servlet.xml <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <!--接口实现--> <bean id="userHessian" class="com.beijia.test.hessian.HessianUserServiceImpl" /> 或者Spring注入方式 <bean id="userHessian" class="com.beijia.test.hessian.HessianUserServiceImpl"> <property name="userService" ref="userService"/> </bean> <!-- 使用Spring的HessianServie做代理 BEGIN --> <!-- Name发布Hessian方法 HessianUser--> <bean name="/HessianUser" class="org.springframework.remoting.caucho.HessianServiceExporter"> <!-- name="service"为固定值 ref=接口实现id--> <property name="service" ref="userHessian" /> <!--name="serviceInterface"为固定值 service引用具体的实现接口 --> <property name="serviceInterface" value="com.beijia.test.hessian.IHessianUserService" /> </bean> <!-- END --> <!-- 可以配置多个HessianServiceExporter代理Bean 如上 --> </beans> 3.客户端配置(集成Spring) 1).提供接口Interface IHessianUserService 2).Hessian方法调用 // 获得客户端的Hessian代理工厂bean 集成Spring ApplicationContext contex = new ClassPathXmlApplicationContext("config/remote-client.xml"); IHessianUserService i = (IHessianUserService) contex.getBean("clientUserHessian");<!--Spring集成ID clientUserHessian--> 或者Spring注入方式 private IHessianUserService clientUserHessian; public IHessianUserService getClientUserHessian() { return clientUserHessian; } @Resource public void setClientUserHessian(IHessianUserService clientUserHessian) { this.clientUserHessian = clientUserHessian; } 3).配置Hessian客户端URL调用XMl remote-client.xml。 注意remote-client.xml文件必须放到src目录下(即编译后WEB-INF\classes下)，不能放到WEB-INF下，否则读取不到 <beans> <!-- 客户端Hessian代理工厂Bean --> <bean id="clientUserHessian" class="org.springframework.remoting.caucho.HessianProxyFactoryBean"> <!-- 请求代理Servlet路径 --> <property name="serviceUrl"> <value>http://192.168.18.197:8080/HTest/remote/HessianUser</value> </property> <!-- 接口定义 --> <property name="serviceInterface"> <value>com.beijia.test.hessian.IHessianUserService</value> </property> </bean> </beans> 这样即可实现hessian RPC远程调用。 服务器端只需Dao、Service、Hessian Interface and Imp三层 客户端只需Action、Hessian Interface、View三层
