Java究竟怎么玩？

Loonframework-Inversion of Control（簡稱LIoC），是一款基于Java反射機制的“微型”Ioc實現，部分參考了另外一個IoC實現yan項目（http://yan.codehaus.org/），LIoC能夠運行在JRE1.4及以上版本中（由于LIoC基于Java反射機制，即便是未簽名的Applet也能夠使用），構建LIoC的目地在于以盡可能簡練的方式實現Java組件間的低耦合調用，LIoC對依賴注入的方法沒有任何約束，它可以對javabean的getter/setter，或者有規則的method，乃至任意變量及它們的任意組合進行注入。（另外LIoC尚有一個需要在JRE1.5及以上版本運行的實現，外部接口與此版類似，內部使用了asm3.1類庫及nio包，支持annotation與xml配置，開發中……）

下面我給出一些簡單的應用實例：

以下是幾個示例中使用到的類：

Bar.java

package org.loon.test; public class Bar { Foo foo; public Bar(Foo foo) { this.foo = foo; } public void greeting() { foo.greet(this); } public String toString() { return "bar"; } }

Foo.java

package org.loon.test; public class Foo { private final String hi; public Foo(String hi) { this.hi = hi; } public void greet(Object obj) { System.out.println(hi + " " + obj); } }

Bean.java

package org.loon.test; public class Bean implements IBean { String a; int b; short c; long d; public Bean() { } public Bean(String a, int b, short c, long d) { this.a = a; this.b = b; this.c = c; this.d = d; } public String getA() { return a; } public void setA(String a) { this.a = a; } public int getB() { return b; } public void setB(int b) { this.b = b; } public short getC() { return c; } public void setC(short c) { this.c = c; } public long getD() { return d; } public void setD(long d) { this.d = d; } public void call(String message){ System.out.println(message); } }

IBean.java

package org.loon.test; public interface IBean { void call(String message); String getA(); int getB(); short getC(); long getD(); }

實例一，簡單的注入依賴：

package org.loon.test; import org.loon.framework.ioc.Ioc; import org.loon.framework.ioc.IocFactory; /** * Copyright 2008 - 2009 * * Licensed under the Apache License, Version 2.0 (the "License"); you may not * use this file except in compliance with the License. You may obtain a copy of * the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the * License for the specific language governing permissions and limitations under * the License. * * @project loonframework * @author chenpeng * @email：ceponline@yahoo.com.cn * @version 0.1 */ public class Sample1 { public static void main(String[] args) { // 構造函數 Object[] constructor = { "hello" }; // 綁定指定類及構造函數 Ioc ioc = IocFactory.bind(Foo.class, constructor); // 獲得指定類的實體對象 Foo foo = (Foo) ioc.getObject(); foo.greet("Testing"); // 釋放資源 IocFactory.destroy(); } }

實例二，多組件聯合操作：

package org.loon.test; import org.loon.framework.ioc.IocContainer; /** * Copyright 2008 - 2009 * * Licensed under the Apache License, Version 2.0 (the "License"); you may not * use this file except in compliance with the License. You may obtain a copy of * the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the * License for the specific language governing permissions and limitations under * the License. * * @project loonframework * @author chenpeng * @email：ceponline@yahoo.com.cn * @version 0.1 */ public class Sample2 { public static void main(String[] args) { // 創建一個ioc容器 IocContainer container = new IocContainer(); // 添加字符串"hello" container.addValue("hello"); // 添加Foo的構造器Foo container.addConstructor(Foo.class); // 添加Bar的構造器 container.addConstructor(Bar.class); // 獲得Bar的實例 Bar bar = (Bar) container.getInstance(Bar.class); bar.greeting(); // 釋放資源 container.destroy(); } }

實例三，虛調用指定對象：

package org.loon.test; import java.io.PrintStream; import org.loon.framework.ioc.Ioc; import org.loon.framework.ioc.IocFactory; /** * Copyright 2008 - 2009 * * Licensed under the Apache License, Version 2.0 (the "License"); you may not * use this file except in compliance with the License. You may obtain a copy of * the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the * License for the specific language governing permissions and limitations under * the License. * * @project loonframework * @author chenpeng * @email：ceponline@yahoo.com.cn * @version 0.1 */ public class Sample3 { public static void main(String[] args) { PrintStream out = System.out; // Ioc ioc = IocFactory.bind(Bean.class.getName(),new Object[]{"測試",new // Integer(1), new Short((short)2), new Long(3)}); // 以字符串方式獲得Bean實例 Ioc ioc = IocFactory.bind(Bean.class.getName()); // PS：lfioc能夠自動識別set、get方法，比如set字段a時，a、A、setA三種寫法在lfioc中都是允許的。 // 為Bean中setA注入數據 ioc.setMethod("a", "加強紀律性，革命無不勝"); // 為setB注入數據 ioc.setMethod("setB", 1); try { // 執行方法getB out.println("字符串調用getB:" + ioc.doInvoke("b")); // 執行方法getA out.println("字符串調用getA:" + ioc.doInvoke("getA")); // 執行方法call ioc.doInvoke("call",new Object[]{"好好學習,天天向上"}); } catch (Exception e) { e.printStackTrace(); } out.println(); // 獲得IBean接口 IBean itest = (IBean) ioc.getObject(); // 執行方法getA out.println("接口調用getA:" + itest.getA()); // 執行方法getB out.println("接口調用getB:" + itest.getB()); // 執行方法call itest.call("天天學習，好好向上"); } }

近期鄙人博客中總是在寫關于Java游戲開發的教程，但是很遺憾沒啥子人氣……偶觀察了一下丟在博客上的wowzio插件，發現很多網友都是查非Java游戲開發的內容轉過來的|||……愛不夠啊≡(▔﹏▔)≡，沒動力了~~~于是非常緩慢的在寫TLOH文檔， 自己挖自己的墳， 又開始鼓搗Loonframework的非游戲部分|||……

不過我知道我國有部分人士以“使用輪子為榮，發明輪子為恥”，所以同樣不寄希望于有什么人使用乃至于完善這個組件≧△≦，不過愚以為這里面部分針對class操作的函數吾輩寫的還是比較省事的，有需要的可以拆出去單用，反正是開源的……但是，偶很“厚道”的將注釋幾乎都刪了，想拆就自己琢磨吧，吼吼(-__-)b……
