用JacksonXML反序列化CDATA - 无法识别的属性异常

Question

我正在使用jackson库（2.5.2）并试图反序列化一些实际上具有CDATA部分的XML。

看来Jackson 2.5增加了对CDATA的支持。

这里是我的类，它有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; 
} 

}

，我得到下面的异常。根本就没有办法用jackson反序列化CDATA？

看来，使用JacksonXmlText工作正常，但当我需要序列化回来我需要的值在CDATA而不是文本。

这是我第一次使用杰克逊这个，所以我可能会错过一些明显的东西。

谢谢

Answer 1

同时使用注释：

@JacksonXmlCData 
@JacksonXmlText 

它的伎俩。那很好！
