Java中Json转List方法

Java利用Json-lib包进行json字符串转换成List集合

JSONArray转换List用法实例

public void JSON2List() {
    try {
        fail("==============JSON Arry String >>> Java List ==================");
        String json = "{\"address\":\"chian\",\"birthday\":{\"birthday\":\"2010-11-22\"}," + "\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";
        json = "[" + json + "]";
        jsonArray = JSONArray.fromObject(json);
        List < Student > list = JSONArray.toList(jsonArray, Student.class);
        System.out.println(list.size());
        System.out.println(list.get(0));

        list = JSONArray.toList(jsonArray);
        System.out.println(list.size());
        System.out.println(list.get(0)); //MorphDynaBean
    } catch(Exception e) {
        e.printStackTrace();
    }
}

执行结果：

==============JSON Arry String >>> Java List ==================
1
tom#22#chian#2010-11-22#email@123.com
1
net.sf.ezmorph.bean.MorphDynaBean@141b571[{id=22, birthday=net.sf.ezmorph.bean.MorphDynaBean@b23210[{birthday=2010-11-22}], address=chian, email=email@123.com, name=tom}]

JSONSerializer转换List方法实例

String json = "[\"first\",\"second\"]";
JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON(json);
List output = (List) JSONSerializer.toJava(jsonArray);
