hessian 在spring mvc中的应用
本节请参考 hessian 入门
接口完全一样， 这里使用maven来管理。

</build>二、增加 hessian-context.xml
这个文件用来定义接口
<bean id="helloServiceImpl" class="org.ifly.edu.hessian.hello.HelloServiceImpl" />
<!-- 使用HessianServiceExporter 将普通bean导出成Hessian服务 -->
<bean name="/service" class="org.springframework.remoting.caucho.HessianServiceExporter">
<property name="service" ref="helloServiceImpl" />
<!-- Hessian服务的接口 -->
<property name="serviceInterface" value="org.ifly.edu.hessian.hello.HelloService" />
</bean>三、修改web.xml
<servlet>
<servlet-name>hessianServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/hessian/hessian-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>hessianServlet</servlet-name>
<url-pattern>/hessian/*</url-pattern>
</servlet-mapping>通过以上三部，服务器端已经定义好了.
四、客户端代码
定义 hessian-client.xml
<bean id="hessianClient" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
<property name="serviceUrl">
<value>http://localhost:8080/techStudy/hessian/service</value>
</property>
<property name="serviceInterface">
<value>org.ifly.edu.hessian.hello.HelloService</value>
</property>
</bean>然后通过spring 获取 hessianClient 来执行，如：
public class HessianServiceTest {
@SuppressWarnings("resource")
@Test
public void testService() throws MalformedURLException {
ApplicationContext context = new ClassPathXmlApplicationContext(
"config/hessian/hessian-client.xml");
HelloService hello = (HelloService) context.getBean("hessianClient");
System.out.println(hello.sayHello("pangzhw"));
}
}
