由于系統(tǒng)中是用Json傳輸數(shù)據(jù)的，我覺得在這里有必要把Java和Flex處理Json數(shù)據(jù)分別介紹一下，今天我們先介紹Java處理Json數(shù)據(jù)。java里面已經(jīng)有開源包實現(xiàn)了把一個Java對象轉(zhuǎn)換為JSon對象， 它就是 http://www.json.org/java/, 各位讀者可以在這個網(wǎng)站上面去下載jar包。首先創(chuàng)建一個自己的public的class，需要轉(zhuǎn)換的類必須是public的，如果不是public的，這里轉(zhuǎn)換不成功，我在寫這篇文章的時候就遇到了這樣的問題，百度了半天才解決，但是具體原因是什么，我沒有深究，個人估計大概是非public的類在進(jìn)行反射的時候有問題。

相關(guān)包的介紹：請大家在下載包的時候，一定要注意包的版本

MyBeanProperty.java

package com.jack.zhang.json; /** * @author Jack Zhang * @version vb1.0 * @Email virgoboy2004@163.com * @Date 2012-4-15 */ public class MyBeanProperty { private String code = "code"; public String getCode() { return code; } public void setCode(String code) { this.code = code; } }

MyBean.java

package com.jack.zhang.json; import net.sf.json.JSONFunction; public class MyBean { private String name = "json"; private MyBeanProperty myBeanProperty = new MyBeanProperty(); private int pojoId = 1; private char[] options = new char[] { 'a', 'f' }; private String func1 = "function(i){ return this.options[i]; }"; private JSONFunction func2 = new JSONFunction( new String[] { "i" }, "return this.options[i];"); public String getName() { return name; } public void setName(String name) { this.name = name; } public int getPojoId() { return pojoId; } public void setPojoId(int pojoId) { this.pojoId = pojoId; } public char[] getOptions() { return options; } public void setOptions(char[] options) { this.options = options; } public String getFunc1() { return func1; } public void setFunc1(String func1) { this.func1 = func1; } public JSONFunction getFunc2() { return func2; } public void setFunc2(JSONFunction func2) { this.func2 = func2; } public MyBeanProperty getMyBeanProperty() { return myBeanProperty; } public void setMyBeanProperty(MyBeanProperty myBeanProperty) { this.myBeanProperty = myBeanProperty; } }

Test.java

package com.jack.zhang.json; import net.sf.json.JSONObject; /** * @author Jack Zhang * @version vb1.0 * @Email virgoboy2004@163.com * @Date 2012-4-15 */ public class Test { public static void main(String[] args) { MyBean myBean = new MyBean(); JSONObject jsonObject = JSONObject.fromObject(myBean); System.err.println(jsonObject); } }
輸出：

{"func1":function(i){ return this.options[i]; },"func2":function(i){ return this.options[i]; },"myBeanProperty":{"code":"code"},"name":"json","options":["a","f"],"pojoId":1}
