使用 JacksonXML 反序列化 CDATA - UnrecognizedPropertyException

Question

我正在使用 jackson 库 (2.5.2) 并尝试反序列化一些 XML 实际上有 CDATA 部分。

Jackson 2.5 似乎增加了对 CDATA 的支持。

这是我的 class 有 CDATA：

public class Certificate {

@JacksonXmlProperty(localName = "name", isAttribute = true)
private String name;
@JacksonXmlCData
private String data;
@JacksonXmlProperty(localName = "date-added", isAttribute = true)
@JsonFormat(pattern = "EEE MMM d HH:mm:ss z yyyy")
private Date dateAdded;
@JsonFormat(pattern = "EEE MMM d HH:mm:ss z yyyy")
@JacksonXmlProperty(localName = "date-expires", isAttribute = true)
private Date expirationDate;


public void setData(String data) {
    this.data = data;
}

public String getData() {
    return data;
}

public String getName() {
    return name;
}

public Date getDateAdded() {
    return dateAdded;
}

public void setDateAdded(Date dateAdded) {
    this.dateAdded = dateAdded;
}

}

我得到以下异常。有什么办法可以用杰克逊反序列化 CDATA 吗？

似乎使用 JacksonXmlText 工作正常，但当我需要序列化回来时，我需要值在 CDATA 而不是文本中。

这是我第一次为此使用 jackson，所以我可能遗漏了一些明显的东西。

谢谢，

Answer 1

同时使用两个注释：

@JacksonXmlCData
@JacksonXmlText

它成功了。太好了！
