SCA实践-运用tuscany实现SCA（二）

[color=red]注意：本文基于tuscany-sca-1.6.1进行讲解。（未完待整理） [/color]
在SCA实践-运用tuscany实现SCA（一）中介绍了如何构建SCA应用。

本文主要介绍tuscany如何和spring集成。

在 《在SCA实践-运用tuscany实现SCA（一）》介绍了需要的基本数据结构和接口
在和spring集成中，需要修改的代码如下

package org.max.tuscany.demo.service.impl;

import org.max.tuscany.demo.Book;
import org.max.tuscany.demo.service.BookService;
import org.max.tuscany.demo.service.LogService;
import org.max.tuscany.demo.service.SecurityService;
import org.osoa.sca.annotations.Reference;

public class BookServiceImpl implements BookService {


	private SecurityService securityService;

	private LogService logService;

	//@Reference
	public void setLogService(LogService logService) {
		this.logService = logService;
	}

	//@Reference
	public void setSecurityService(SecurityService securityService) {
		this.securityService = securityService;
	}

	@Override
	public Book getBook(Long bookId, Long userId) {
		System.out.println("BookServiceImpl.getBook is invoked");

		if(securityService.securityCheck(userId)){
			logService.log("ok");
			return new Book(bookId,"tuscany in action");
		}else{
			logService.log("go back");
		}
		return null;
	}

}

唯一修改就是去掉了@Reference注解

配置文件修改为如下

<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
	xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0"
	targetNamespace="http://sample" xmlns:sample="http://sample" name="BookSpring">
	<service name="BookService" promote="BookServiceComponent">
			<interface.java interface="org.max.tuscany.demo.service.BookService" />
			<binding.ws />
			<tuscany:binding.rmi host="localhost" port="8099"
				serviceName="BookService" />
		</service>
	<component name="BookServiceComponent">
		<implementation.spring location="META-INF/spring-context/applicationContext_book.xml"/>
	</component>
</composite>

新增加spring配置文件
META-INF/spring-context/applicationContext_book.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sca="http://www.springframework.org/schema/sca"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/sca http://www.osoa.org/xmlns/sca/1.0/spring-sca.xsd">

	<!-- The name must equal with service name in *.composite  -->
	<sca:service name="BookService" type="org.max.tuscany.demo.service.BookService"
		target="BookServiceBean" />

	<bean id="BookServiceBean" class="org.max.tuscany.demo.service.impl.BookServiceImpl">
		<property name="logService" ref="logService" />
		<property name="securityService" ref="securityService" />

	</bean>

	<bean id="logService" class="org.max.tuscany.demo.service.impl.LogServiceImpl"></bean>
	<bean id="securityService" class="org.max.tuscany.demo.service.impl.SecurityServiceImpl"></bean>

</beans> 

部署文件
<contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"
xmlns:sample="http://sample">
<deployable composite="sample:BookSpring"/>
</contribution>

其他代码不变。
