Brap和Spring整合（简单权限验证）

     在使用Spring的发布WebService的实现，如果采用Brap实现更加简单，权限验证只需要添加相关的验证接口

服务接口：

package com.easyway.remoting.braps;



/**
 * 服务实现的接口
 * @author longgangbai
 *
 */
public interface HelloService {
    public String sayHello(String name);
}

 

服务的实现类：

package com.easyway.remoting.braps;
/**
 * 服务端的服务实现类
 * @author longgangbai
 *
 */
public class HelloServiceImpl implements HelloService {
    public String sayHello(String name) {
      return "Hello world, " + name;
    }
}

 spring的配置如下：

<?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:lang="http://www.springframework.org/schema/lang"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-2.5.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"
	default-autowire="no" default-lazy-init="true">
	<!--  服务包装类-->
	<bean id="helloRemoteService"
		class="no.tornado.brap.servlet.ServiceWrapper">
		<property name="service" ref="helloService" />
		<property name="authenticationProvider"
			ref="authenticationProvider" />
		<property name="authorizationProvider"
			ref="authorizationProvider" />
	</bean>
	<!-- 服务端服务实现类 -->
	<bean id="helloService"
		class="com.easyway.remoting.braps.HelloServiceImpl" />
	<!--  用户验证的信息-->
	<bean id="authenticationProvider"
		class="no.tornado.brap.auth.SingleUsernamePasswordAuthenticator">
		<property name="username" value="admin" />
		<property name="password" value="admin" />
	</bean>
	<!-- 权限验证器-->
	<bean id="authorizationProvider"
		class="no.tornado.brap.auth.AuthenticationRequiredAuthorizer" />

</beans>

 

web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
		 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
		 version="2.4">

	<display-name>BRAP Test</display-name>
    <!-- 设置Spring的配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
 <!-- 需要暴露spring的一种服务 -->
	<servlet>
		<servlet-name>hello</servlet-name>
		<servlet-class>no.tornado.brap.spring.SpringProxyServlet</servlet-class>
		<!-- 需要暴露的bean名称 -->
        <init-param>
            <param-name>beanName</param-name>
            <param-value>helloRemoteService</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
	</servlet>
   <!-- 暴露的路径名称 -->
	<servlet-mapping>
		<servlet-name>hello</servlet-name>
		<url-pattern>/remoting/hello</url-pattern>
	</servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

</web-app>

 

客户端调用如下：

package com.easyway.ws.brap.service.client;

import java.net.MalformedURLException;

import no.tornado.brap.client.ServiceProxyFactory;
import no.tornado.brap.common.UsernamePasswordPrincipal;

import com.easyway.remoting.braps.HelloService;

/**
 * 客户端调用代码
 * @author longgangbai
 *
 */
public class BrapClient {
	public static void main(String[] args) throws MalformedURLException {
		//客户端验证的用户名和密码
		UsernamePasswordPrincipal upp = new UsernamePasswordPrincipal("admin",
				"admin");
		//客户端的服务信息
		HelloService service = ServiceProxyFactory.createProxy(
				HelloService.class,
				"http://localhost:8080/BrapServiceWS/remoting/hello", upp);
		//客户端的操作
		System.out.println(service.sayHello("Hello"));

	}
}
