JSON-lib这个Java类包用于把bean，map和XML转换成JSON并能够把JSON转回成bean和DynaBean.

还要需要的第3方包：org.apache.commons（3.2以上版本）
org.apache.oro
net.sf.ezmorph（ezmorph-1.0.4.jar）

1、List
Java代码
- boolean[] boolArray = new boolean[]{true,false,true};
- JSONArray jsonArray1 = JSONArray.fromObject( boolArray );
- System.out.println( jsonArray1 );
- // prints [true,false,true]
- List list = new ArrayList();
- list.add( "first" );
- list.add( "second" );
- JSONArray jsonArray2 = JSONArray.fromObject( list );
- System.out.println( jsonArray2 );
- // prints ["first","second"]
- JSONArray jsonArray3 = JSONArray.fromObject( "[json,is,easy]" );
- System.out.println( jsonArray3 );
- // prints ["json","is","easy"]
2、Map
Java代码
- Map map = new HashMap();
- map.put( "name", "json" );
- map.put( "bool", Boolean.TRUE );
- map.put( "int", new Integer(1) );
- map.put( "arr", new String[]{"a","b"} );
- map.put( "func", "function(i){ return this.arr[i]; }" );
- JSONObject json = JSONObject.fromObject( map );
- System.out.println( json );
- //{"func":function(i){ return this.arr[i]; },"arr":["a","b"],"int":1,"name":"json","bool":true}
3、BEAN
Java代码
- /**
- * Bean.java
- private String name = "json";
- 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];");
- */
- JSONObject jsonObject = JSONObject.fromObject( new JsonBean() );
- System.out.println( jsonObject );
- //{"func1":function(i){ return this.options[i]; },"pojoId":1,"name":"json","options":["a","f"],"func2":function(i){ return this.options[i]; }}
4、BEANS
Java代码
- /**
- * private int row ;
- private int col ;
- private String value ;
- *
- */
- List list = new ArrayList();
- JsonBean2 jb1 = new JsonBean2();
- jb1.setCol(1);
- jb1.setRow(1);
- jb1.setValue("xx");
- JsonBean2 jb2 = new JsonBean2();
- jb2.setCol(2);
- jb2.setRow(2);
- jb2.setValue("");
- list.add(jb1);
- list.add(jb2);
- JSONArray ja = JSONArray.fromObject(list);
- System.out.println( ja.toString() );
- //[{"value":"xx","row":1,"col":1},{"value":"","row":2,"col":2}]
