使用net.sf.json遍历Json数组

import org.junit.Test;
import java.util.Iterator;
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

public class JsonArrayTest {

	@SuppressWarnings("unchecked")
	@Test
	public void test1() {
		String arrStr = "[{key:'a',value:'1'},{key:'b',value:'2'},{key:'c',value:'3'}]";
		JSONArray jsonArray = JSONArray.fromObject(arrStr);
		for (int i = 0; i < jsonArray.size(); i++) {
			JSONObject jsonObj = jsonArray.getJSONObject(i);
			Iterator<String> iterator = jsonObj.keys();
			while (iterator.hasNext()) {
				String key = iterator.next();
				System.out.println(key + ":" + jsonObj.getString(key) + " ");
			}
		}
	}
