Spring 企业级开发应用---------burlap和spring的远程服务整合的应用

博客分类：
Spring 开发应用

企业应用应用服务器SpringBeanServlet

使用burlap和spring整合发布远程服务

开发步骤

1服务端接口和实现的开发

2服务端的web.xml的配置信息

3服务端的spring和burlap的配置信息

4 部署发布服务端服务

5 客户端的配置信息

6客户端的访问信息

服务端接口和实现类

服务端的服务定义类

package cn.com.huawei.burlap.service;

import java.util.List;

public interface IUserService {

public List getUsernames();

}

服务端的服务实现类

package cn.com.huawei.burlap.service.impl;

import java.util.ArrayList;

import java.util.List;

import cn.com.huawei.burlap.service.IUserService;

public class UserService implements IUserService{

public List getUsernames()

{

List<String> usernames=new ArrayList<String>();

usernames.add("xiaobai");

usernames.add("xiaoli");

return usernames;

}

}

服务的端配置：

web。xml的配置

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

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

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

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<!--spring的配置文件的信息-->

<context-param>

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

<param-value>/WEB-INF/applicationContext.xml</param-value>

</context-param>

<!---使用上下文的加载spring-->

<listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

<!---使用spring的分发器将服务分发到Burlap的响应的控制类-->

<servlet>

<servlet-name>remoting</servlet-name>

<servlet-class>

org.springframework.web.servlet.DispatcherServlet

</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>remoting</servlet-name>

<url-pattern>/remoting/*</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

注意使用spring的分发器时必须使用响应的配置信息的 servlet-name-servlet.xml配置文件：如remoting-servlet.xml

信息如下：

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

<beans

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

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

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!---远程服务的burlap的在spring中配置信息-->

<bean name="/Userservice-burlap" class="org.springframework.remoting.caucho.BurlapServiceExporter">

<property name="service">

<ref bean="userservicetarget"/>

</property>

<property name="serviceInterface">

<value>cn.com.huawei.burlap.service.IUserService</value>

</property>

</bean>

</beans>

applicationContext。xml的配置信息如下：

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

<beans

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

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

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!--服务实现类的--->

<bean id="userservicetarget" class="cn.com.huawei.burlap.service.impl.UserService"/>

</beans>

spring和burlap的配置文件

spring和burlap的客户端使用远程服务的服务

package cn.com.huawei.burlap.client;

import java.util.List;

import cn.com.huawei.burlap.service.IUserService;

public class BurlapClient {

private IUserService userservice;

public IUserService getUserservice() {

return userservice;

}

public void setUserservice(IUserService userservice) {

this.userservice = userservice;

}

public List getUsernames() {

return this.userservice.getUsernames();

}

}

package cn.com.huawei.burlap.client;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class BurlapTest {

public static void main(String[] args) {

ApplicationContext ctx = new ClassPathXmlApplicationContext(

"applicationContext.xml");

BurlapClient hessina = (BurlapClient) ctx.getBean("burlapclient");

System.out.println("burlapclient:" + hessina.getUsernames());

}

}

client.properties 属性配置文件

# Properties file with server URL settings for remote access.

# Applied by PropertyPlaceholderConfigurer from "clientContext.xml".

serverName=localhost

httpPort=8080

rmiPort=1099

serverPath=SpringBurlap

contextPath=remoting/Userservice-burlap
