Java flexjson序列化组合JSON对象

Question

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

/**
 * 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;

和将对象转换为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);
}

我使用flexjson和它的JSONSerializer对象。我的问题是，它只转换标题和subTitle成员JSON，数组不转换。谁能告诉我如何将数组包含到JSON中?谢谢。

我已经算出来了，下面是正确的函数:

// 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);
}
