如何从jsonarray中取数据

如何从jsonarray中取数据

需要写一个方法，把json数据转换成list集合数据
public static List jsonToBean(String data, Object bean) {
List list = new ArrayList()

try {
JSONArray array

try {
array = new JSONArray(data)
for (int i = 0 i < array.length() i ) {
Object toBean = getBean(bean)
JSONObject ob = new JSONObject()
ob = (JSONObject) array.get(i)
toBean = jsonStrToBean(ob, toBean)
list.add(toBean)

}
return list
} catch (JSONException e) {
try {
Object obj = null
JSONObject jsonObj = new JSONObject(data)
Object toBean = getBean(bean)
toBean = jsonStrToBean(jsonObj, toBean)
list.add(toBean)
return list
} catch (JSONException e1) {
log.error("Error covert String to JSONObject", e)
e1.printStackTrace()
}
e.printStackTrace()
log.error("Error covert String to JSONArray", e)
}

} catch (SecurityException e) {
e.printStackTrace()
}
return list
}
然后取出list集合数据中的值应该没问题了吧。
