　　Spring 针对远程访问服务提供的一个remote包其的的是提供一套统一的远程服务发布功能

　　先来看一下Spring 支持那些远程服务功能 RMI服务 Hessian或者Burlap通过HTTP远程调用服务 HTTP调用器暴露服务

　　下面用一个例子来看一下Spring 是怎样对这些服务进行统一的封装和管理

　　先看一下服务器端的源代码

public interface IBookService Book getById(String id);public class Book public String name; public String id; public String author; public class BookService implements IBookService public Book getById(String id) return BookStore getById(id);

　　客户端源代码

public class BookQueryService private IBookService bookService; public void setAccountService(IBookService bookService) this bookService = bookService; public Book getBookById(String id) return bookService getById(id); //客户端调用示例public static void main(String[] args) ClassPathXmlApplicationContext context; context = new ClassPathXmlApplicationContext( applicationContext xml ); BookQueryService bookQueryService = (BookQueryService) context getBean( bookQueryService ); Book book = bookQueryService getBookById( );

　　使用Spring 发布 RMI服务示例

服务器端配置:<bean id= bookService class= xmatthew spring remote BookService ></bean><bean class= springframework remoting rmi RmiServiceExporter > <! does not necessarily have to be the same name as the bean to be exported > <property name= serviceName value= bookService /> <property name= service ref= bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /> <property name= registryPort value= /></bean>客户端配置:<bean class= xmatthew spring remote client BookQueryService > <property name= bookService ref= bookService /></bean><bean id= bookService class= springframework remoting rmi RmiProxyFactoryBean > <property name= serviceUrl value= rmi://localhost: /bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /></bean>

　　使用Spring 发布基于Http的Hessian服务示例

　　注 Hessian提供一种基于HTTP的二进制远程协议它是由Caucho创建的可以在找到更多有关Hessian的信息

　　首为使用Hessian 需要为其配置Spring 的 DispatcherServlet把下面的配置加入到web xml中

<servlet> <servlet name>remoting</servlet name> <servlet class> springframework web servlet DispatcherServlet</servlet class> <load on startup> </load on startup></servlet><servlet mapping> <servlet name>remoting</servlet name> <url pattern>/remoting/*</url pattern></servlet mapping> 服务器端配置:<bean id= bookService class= xmatthew spring remote BookService ></bean><bean name= /bookService class= springframework remoting caucho HessianServiceExporter > <property name= service ref= bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /></bean>客户端配置:<bean class= xmatthew spring remote client BookQueryService > <property name= bookService ref= bookService /></bean><bean id= bookService class= springframework remoting caucho HessianProxyFactoryBean > <property name= serviceUrl value=//localhost: /bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /></bean>

　　使用Spring 发布基于Http的Burlap服务示例

　　Burlap 它是一个基于XML的Hessian替代方案它的配置方法和上述Hessian的一样只要把 Hessian 换成 Burlap 就行了

　　服务器端使用 springframework remoting caucho BurlapServiceExporter 发布服务客户端使用 springframework remoting caucho BurlapProxyFactoryBean

　　使用Spring 发布基于HTTP调用器暴露服务

　　和使用自身序列化机制的轻量级协议Burlap和Hessian相反 Spring HTTP调用器使用标准Java序列化机制来通过HTTP暴露业务

　　但其配置与Burlap和Hessian很相近

服务器端配置:<bean id= bookService class= xmatthew spring remote BookService ></bean><bean name= /bookService class= springframework remoting > <property name= service ref= bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /></bean>客户端配置:<bean class= xmatthew spring remote client BookQueryService > <property name= bookService ref= bookService /></bean><bean id= bookService class= springframework remoting > <property name= serviceUrl value=//localhost: /bookService /> <property name= serviceInterface value= xmatthew spring remote IBookService /></bean> cha138/Article/program/Java/ky/201311/28488
