Spring Hessian配置使用

Spring 提供简便的远程调用服务

一、下载hessian.jar包

二、服务器端配置

1、新建applicationContext-hessianServer.xml

<?xml version="1.0" encoding="UTF-8"?>

略....

<description>Hessian Configer</description>

<!--辅助类 可以不添加 -->

<bean id="lazySerializer" class="com.cmmb.mall.util.hessian.LazyHibernateSerializerFactory"></bean> 

<!--merchantServiceExporter 暴露服务名 -->

<bean name="merchantServiceExporter" class="org.springframework.remoting.caucho.HessianServiceExporter">

<property name="service" ref="merchantService" />

<property name="serviceInterface" value="com.ws.api.MerchantService" />

<property name="serializerFactory" ref="lazySerializer"></property>  

</bean>

<bean id="merchantService" class="com.ws.impl.MerchantServiceImpl" />

2、web.xml配置

<servlet>

  <!--merchantServiceExporter 暴露服务名 相对应 -- >

<servlet-name>merchantServiceExporter</servlet-name>

<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet

</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>merchantServiceExporter</servlet-name>

<url-pattern>/remoting/MerchantService</url-pattern>

</servlet-mapping>

三、客户端配置

1、新建applicationContext-hessianClient.xml

<?xml version="1.0" encoding="UTF-8"?>

略........

<bean id="merchantService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">

<property name="serviceUrl" value="http://192.168.1.117:8080/merchantmanage/remoting/MerchantService" />

<property name="serviceInterface" value="com.cmmb.mall.ws.api.MerchantService" />

</bean>

四、测试

pubilc class Test{

 //merchantService 配置的bean

ThirdProductService thirdProductService = (ThirdProductService) ac.getBean(" merchantService ");

public static void main(String[] args) {

//调用远程接口

List<ThirdProduct> tps =  thirdProductService.listByStatus("ONLINE");

}

}

------------------------------------------------------------------------------

辅助类：

public class LazyHibernateSerializerFactory extends SerializerFactory {

public static String versionString = "3";

@SuppressWarnings("unchecked")

@Override

public Serializer getSerializer(Class cls) throws HessianProtocolException {

try {

if (versionString.startsWith("3")

&& Class.forName(

"org.hibernate.collection.PersistentCollection")

.isAssignableFrom(cls)) {

return new LazySerializerForHibernate3(cls);

} else if (versionString.startsWith("4")

&& Class

.forName(

"org.hibernate.collection.spi.PersistentCollection")

.isAssignableFrom(cls)) {

return new LazySerializerForHibernate4(cls);

}

} catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return super.getSerializer(cls);

}

public static void main(String[] args) {

org.hibernate.engine.VersionValue hVersion ;

System.out.println(org.hibernate.engine.VersionValue.NEGATIVE);

}

}
