Hessian集成Spring使用案例

2017-09-28 09:41 357 查看

演示例子分为三部分：Client 、Server、Skeleton; 其中，Client 是通过Hessian调用远程服务的客户端；Server是通过Hessian对外提供服务的服务端；Skeleton 是接口桥梁。

一、Client 配置

1. 新增文件 hessian.properties ，配置内容如下：
business.log.url=http://192.168.0.125:8087/server/hessian/logBusiness
2. Pom 增加配置信息，如下：
<dependency>

<groupId>hessian</groupId>

<artifactId>skeleton</artifactId>

<version>1.0</version>

</dependency>
<dependency>

<groupId>com.caucho</groupId>

<artifactId>hessian</artifactId>

<version>4.0.51</version>

</dependency>
3. Spring 配置文件增加信息如下：
<bean id="propertyConfigurer"

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="locations">

<list>

<value>classpath:jdbc.properties</value>

<value>classpath:hessian.properties</value>

</list>

</property>

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

<property name="serviceUrl" value="${business.log.url}" />

<property name="serviceInterface" value="com.kevin.service.ILogRemoteBusiness" />

</bean>

4. 客户端通过Hessian调用远程服务
@Controller

@RequestMapping("remote")

public class HessianTest {

@Resource

private ILogRemoteBusiness logRemoteBusiness;

@RequestMapping(value = "/test", method = RequestMethod.GET)

@ResponseBody

public String test(HttpServletRequest request, HttpServletResponse response) {

System.out.println("ok!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");

logRemoteBusiness.sayHello();

return "true";

}

}

二、Server 配置

1. Pom 配置同上
2. 增加 spring-hessian-server.xml 文件，内容如下：
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">


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

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

<property name="serviceInterface" value="com.kevin.service.ILogRemoteBusiness" />

</bean>

</beans>

3. Web.xml 配置过滤器，如下：
<servlet>

<servlet-name>hessian-servlet</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:spring/spring-hessian-server.xml</param-value>

</init-param>

<load-on-startup>2</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>hessian-servlet</servlet-name>

<url-pattern>/hessian/*</url-pattern>

</servlet-mapping>

4. 实现接口，提供服务
@Service

public class LogRemoteBusinessImpl implements ILogRemoteBusiness {

public void sayHello() {

System.out.println("===============This is server say hello==============");

}

}

三、skeleton（接口）配置

1. 提供接口
public interface ILogRemoteBusiness {

public void sayHello();

}
2. 将 skeleton.jar 发布到远程仓库
