问题描述
我收到以下回复，并尝试使用JAXB解析它，但是下面的代码返回错误。
I am receiving following response and am trying to to parse it using JAXB but following code returns error below.
Exception in thread "main" org.springframework.http.converter.HttpMessageConversionException: Could not instantiate JAXBContext for class [class com.easytobook.EasytobookResponse]: 1 counts of IllegalAnnotationExceptions; nested exception is com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
com.easytobook.Roomtype#totalTaxesAndFees has mutually exclusive annotations @javax.xml.bind.annotation.XmlAttribute and @javax.xml.bind.annotation.XmlElement
this problem is related to the following location:
at @javax.xml.bind.annotation.XmlAttribute(name=EUR, required=false, namespace=##default)
我知道异常与totalTaxsesAndFees有关，但我不知道如何解决这个问题。
I know exception is related to totalTaxsesAndFees but I am not sure how to solve the issue.

推荐答案
错误消息说明了一切：
com.easytobook。 Roomtype #totalTaxesAndFees 具有互斥注释@ javax.xml。 bind.annotation。 XmlAttribute 和@ javax.xml.bind.annotation。 XmlElement
com.easytobook.Roomtype#totalTaxesAndFees has mutually exclusive annotations @javax.xml.bind.annotation.XmlAttribute and @javax.xml.bind.annotation.XmlElement
您的代码有：
@XmlRootElement(name = "Roomtype")
@XmlAccessorType(XmlAccessType.FIELD)
public class Roomtype {
. . .
@XmlAttribute(name="EUR")
@XmlElement(name = "TotalTaxesAndFees")
private double totalTaxesAndFees;
这是不允许的。
您的问题是这些XML元素：
Your problem is these XML elements:
<Roomtype>
<Roomid parentid="2069840686">2069840686</Roomid>
. . .
<Totalrate currency="AUD" EUR="1204.3398">1800</Totalrate>
<TotalTaxesAndFees currency="AUD" EUR="0">0</TotalTaxesAndFees>
<TotalChargeable currency="AUD" EUR="1204.3398">1800</TotalChargeable>
<Reckratetotal currency="AUD" EUR="1204.3398">1800</Reckratetotal>
例如，以下字段注释告诉JAXB parentid 是 Roomtype 的属性，当你想要它作为 Roomid 的属性时：
For example, the following field annotation tells JAXB that parentid is an attribute of Roomtype, when you want it as an attribute of Roomid:
public class Roomtype {
@XmlAttribute(name = "parentid")
private String parentid;
相反，为了在< Roomid> <上设置属性元素，你需要一个 Roomid 类（你不需要 @XmlRootElement ） ：
Instead, in order to have an attribute on the <Roomid> element, you need a Roomid class (and you don't need the @XmlRootElement):
@XmlAccessorType(XmlAccessType.FIELD)
public class Roomid {
@XmlAttribute(name = "parentid")
private String parentid;
@XmlValue
private long roomId;
}
您的4个元素具有相同的结构，因此它们可以共享一个类：
Your 4 total elements have the same structure, so they can share a single class:
@XmlAccessorType(XmlAccessType.FIELD)
public class Total {
@XmlAttribute(name = "currency")
private String currency;
@XmlAttribute(name = "EUR")
private double eur;
@XmlValue
private double total;
}
然后使用这两个类：
@XmlAccessorType(XmlAccessType.FIELD)
public class Roomtype {
@XmlElement(name = "Roomid")
private Roomid roomid;
. . .
@XmlElement(name = "Totalrate")
private Total totalrate;
@XmlElement(name = "TotalTaxesAndFees")
private Total totalTaxesAndFees;
@XmlElement(name = "TotalChargeable")
private Total totalChargeable;
@XmlElement(name = "Reckratetotal")
private Total reckratetotal;
