json字符串转List

data class Person(val name: String="",val age:Int=0) {

}

Java代码实现:

    //json转List
    public static  java.util.List getListFromJson(String json, Class clazz) {
        try {
            T[] arr = new Gson().fromJson(json, clazz);
            return Arrays.asList(arr);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
    
    public static void main(String[] args) {
        String str = "[{\"age\":1,\"name\":\"kongpf\"},{\"age\":2,\"name\":\"kongpf\"},{\"age\":3,\"name\":\"kongpf\"},{\"age\":4,\"name\":\"kongpf\"},{\"age\":5,\"name\":\"kongpf\"},{\"age\":6,\"name\":\"kongpf\"},{\"age\":7,\"name\":\"kongpf\"},{\"age\":8,\"name\":\"kongpf\"},{\"age\":9,\"name\":\"kongpf\"},{\"age\":10,\"name\":\"kongpf\"}]";
        java.util.List list = getListFromJson(str, Person[].class);
        list.forEach(person -> {
            System.out.println(person.toString());
        });
    }

kotlin代码实现:

//json转list
fun  getListFromJson(json: String?, clazz: Class>): List? {
    try {
        val arr: Array = Gson().fromJson(json, clazz)
        return Arrays.asList(*arr)
    } catch (e: Exception) {
        e.printStackTrace()
    }
    return null
}

fun main() {

    var str="[{\"age\":1,\"name\":\"kongpf\"},{\"age\":2,\"name\":\"kongpf\"},{\"age\":3,\"name\":\"kongpf\"},{\"age\":4,\"name\":\"kongpf\"},{\"age\":5,\"name\":\"kongpf\"},{\"age\":6,\"name\":\"kongpf\"},{\"age\":7,\"name\":\"kongpf\"},{\"age\":8,\"name\":\"kongpf\"},{\"age\":9,\"name\":\"kongpf\"},{\"age\":10,\"name\":\"kongpf\"}]"
    var list= getListFromJson(str, Array::class.java)
    list?.forEach {
        println(it)
    }
}
