Question

我有一个Java类，我想从类的对象生成一个JSON字符串。但是，班级成员如下：

/**
 * The set containing the footer texts
 */
public HeaderOrFooter[] footers = null;
/**
 * The title of the word cloud
 */
public HeaderOrFooter title;
/**
 * The subtitle of the word cloud
 */
public HeaderOrFooter subTitle;
/**
 * The set of rectangles to be drawn
 */
public Rectangle[] rectangles;
/**
 * The set of round rectangles to be drawn
 */
public RoundRectangle[] roundRectangles;
/**
 * The set of lines to be drawn
 */
public Line[] lines;
/**
 * The set of polygons to be drawn
 */
public Polygon[] polygons;
/**
 * The set of words to be drawn
 */
public Word[] words;

我将对象转换为JSON的方法如下所示：

public String convertToJSON()
{
    flexjson.JSONSerializer jsonSerializer = new flexjson.JSONSerializer();
    jsonSerializer.exclude("class");
    jsonSerializer.exclude("subTitle.class");
    jsonSerializer.exclude("title.class");
    return jsonSerializer.serialize(this);
}

我正在使用flexjson及其JSONSerializer对象。我的问题是它只将title和subTitle成员转换为JSON，不转换数组。有人可以告诉我如何将数组包含到我的JSON中？感谢。

我已经弄清楚了，这是正确的功能：

// Re-using the serializer as per "Thread Safety and Reuse"
// section of http://flexjson.sourceforge.net/
public static final flexjson.JSONSerializer jsonSerializer;
static {
    jsonSerializer = new flexjson.JSONSerializer().exclude("*.class");
}

public String toJSON() {
    return jsonSerializer.deepSerialize(this);
}

Java flexjson序列化组合的JSON对象
