我如何在java中实现以下代码

Question

this code is in php where there are different type of json objects in an array

function data($text, $number, $user_id, $port = NULL, $encoding = NULL)
    {
    $data = array
    (
        "text" => "#param#",
        "param" => array
        (
            array(
            "number" => $number,
            "text_param" => array($text),
            "user_id" => $user_id,
            ),
        ),
    );
    if ($port != NULL) {
        $data["port"] = array($port);
    }

    if ($encoding != NULL) {
        $data["encoding"] = $encoding;
    }
    return $data;
}

what are the possible ways to write the above code in java

Answer 1

Don't look for direct, native support of translating json straight into Java objects, it needs to be done through libraries.

There are a (quite big) number of json libraries - GSON is one that I used, java EE json support is another. Search for others using your preferred search engine.

Answer 2

使用Jackson库将 JSON 解析为 Java 对象。
