在eclipse导入json包 然后用把map转化为json 出错
代码：
import java.util.HashMap;
import java.util.Map;
import net.sf.json.JSONObject;
public class Json_test_class {
public static void main(String[] args) {
// TODO Auto-generated method stub
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.get("name"));
}
}
控制台错误信息
