本文记录的是如何使用Gson处理Array类型数据, 包括将Array对象序列化为Json串以及将Json串反序列化为Array对象.

下面的示例是将数组元素序列化为Json串，如下所示:

Serialization:

1
2
3
4
5
Gson gson = new Gson();
int[] ints = {1, 2, 3, 4, 5};
String[] strings = {"abc", "def", "ghi"};    
System.out.println("json_string: " + gson.toJson(ints));
System.out.println("json_string: " + gson.toJson(strings));

示例中控制台会输出:

1
2
json_string: [1,2,3,4,5]
json_string: ["abc","def","ghi"]

数组的反序列化如下所示:

Deserialization:

1
2
3
4
5
Gson gson = new Gson();
String intsStr = "[1,2,3,4,5]";
String stringsStr = "[\"abc\",\"def\",\"ghi\"]";
int[] ints2 = gson.fromJson(intsStr, int[].class); 
String[] strings2 = gson.fromJson(stringsStr, String[].class);

可以设置断点查看数组中元素。

另外: Gson also support multi-dimensional arrays, with arbitrarily complex element types.
