TUSCANY SCA JAVA (五) 用其他指令碼語言實現元件服務

先來看看整個項目的代碼架構

com.ajun.tuscany.server包主要是加減乘除法的java介面和計算機介面和計算機實作類別。

com.ajun.tuscany.script主要是用指令碼語言來實現加減乘法服務功能。

com.ajun.tuscany.client用戶端調用。

server包主要代碼：

IAdd.java

package com.ajun.tuscany.server;/** * 加法介面 * @author ajun * @e-mail zhaojun2066@gmail.com * @blog http://blog.csdn.net/ajun_studio * @version 建立時間：2012-7-19  下午9:47:25 */public interface IAdd {double add(double n1,double n2);}

ISubtract.java

package com.ajun.tuscany.server;/** * 減法介面 * @author ajun * @e-mail zhaojun2066@gmail.com * @blog http://blog.csdn.net/ajun_studio * @version 建立時間：2012-7-19  下午9:52:00 */public interface ISubtract {double subtract(double n1,double n2);}

IMultiply.java

package com.ajun.tuscany.server;/** * 乘法介面 * @author ajun * @e-mail zhaojun2066@gmail.com * @blog http://blog.csdn.net/ajun_studio * @version 建立時間：2012-7-19  下午9:50:47 */public interface IMultiply {double multiply(double n1,double n2);}

IDivide.java

package com.ajun.tuscany.server;/** * 除法介面 * @author ajun * @e-mail zhaojun2066@gmail.com * @blog http://blog.csdn.net/ajun_studio * @version 建立時間：2012-7-19  下午9:48:53 */public interface IDivide {double divide(double n1,double n2);}

ICalculator.java

package com.ajun.tuscany.server;/** * 電腦介面 * @author ajun * @e-mail zhaojun2066@gmail.com * @blog http://blog.csdn.net/ajun_studio * @version 建立時間：2012-7-19  下午10:02:20 */public interface ICalculator {/** * 加法 * @param n1 * @param n2 * @return */double add(double n1,double n2);/** * 減法 * @param n1 * @param n2 * @return */double subtract(double n1,double n2);/** * 除法 * @param n1 * @param n2 * @return */double divide(double n1,double n2);/** * 乘法 * @param n1 * @param n2 * @return */double multiply(double n1,double n2);}

Calculator.java

package com.ajun.tuscany.server;import org.osoa.sca.annotations.Reference;public class Calculator implements ICalculator{/** * 引用其他組件IAdd，ISubtract，IMultiply,IDivide * @Reference 說明引用其他組件 會和.composite檔案進行配置 */private IAdd add;//加法組件private ISubtract subtract;//減法組件private IMultiply multiply;//乘法組件private IDivide divide;//除法組件public IAdd getAdd() {return add;}@Referencepublic void setAdd(IAdd add) {this.add = add;}public ISubtract getSubtract() {return subtract;}@Referencepublic void setSubtract(ISubtract subtract) {this.subtract = subtract;}public IMultiply getMultiply() {return multiply;}@Referencepublic void setMultiply(IMultiply multiply) {this.multiply = multiply;}public IDivide getDivide() {return divide;}@Referencepublic void setDivide(IDivide divide) {this.divide = divide;}@Overridepublic double add(double n1, double n2) {System.out.println("Server add");return this.add.add(n1, n2);}@Overridepublic double subtract(double n1, double n2) {System.out.println("Server subtract");return this.subtract.subtract(n1, n2);}@Overridepublic double divide(double n1, double n2) {System.out.println("Server divide");return this.divide.divide(n1, n2);}@Overridepublic double multiply(double n1, double n2) {System.out.println("Server multiply");return this.multiply.multiply(n1, n2);}}

script包用於實現java介面中的方法：

AddService.js

//加法，用js實現function add(n1,n2){return n1+n2;}

DivideService.groovy

//用Groovy實現除法def divide(n1,n2){return n1/n2}

MultiplyService.py

#用python實現def multiply(n1,n2):return n1*n2

SubtractService.rb

#減法用Ruby實現def subtract(n1,n2)return n1-n2end

Calculator.composite設定檔
