JSON有三类元素： 

1、结构体（关键字：大括号）（对应的是对象）
2、键值对（关键字：冒号）（对应的是对象里的属性）
3、数组（关键字：中括号）（对应的集合）

范例

{
	"animals": {
		"dog": [{
				"name": "Rufus",
				"breed": "labrador",
				"count": 1,
				"twoFeet": false
			},
			{
				"name": "Marty",
				"breed": "whippet",
				"count": 1,
				"twoFeet": false
			}
		],
		"cat": {
			"name": "Matilda"
		},
		"age": "5"
	}
}

转Java实体类

public class Animals {
    private List<Dog> dog;
    private Cat cat;
    private String age;

    public class Cat {
        private String name;
    }

    public class Dog {
        private String name;
        private String breed;
        private int count;
        private boolean twoFeet;
    }
}
