部署spring-ws web服务时的JAXB异常

Question

我有一个xsd，它使用了使用spring-ws实现的soap web服务。 的类型之一定义如下：

<xsd:complexType name="DateTimeWithTimeZone"> 
     <xsd:annotation> 
     <xsd:documentation>An extension to the standard dateTime, that forces the use of a proper time zone.</xsd:documentation> 
     </xsd:annotation> 
     <xsd:attribute name="DateTime" type="xsd:dateTime" use="required"> 
     <xsd:annotation> 
      <xsd:documentation>The date time value</xsd:documentation> 
     </xsd:annotation> 
     </xsd:attribute> 
     <xsd:attribute name="TimeZone" type="xsd:string" use="optional" default="UTC"> 
     <xsd:annotation> 
      <xsd:documentation>The time zone of the relevant date/time, should be a standard time zone from the Time Zone database at http://www.iana.org/time-zones</xsd:documentation> 
     </xsd:annotation> 
     </xsd:attribute> 
    </xsd:complexType> 

我的问题是，当我的JBoss的负荷，我得到这个异常：

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'marshaller' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.oxm.UncategorizedMappingException: Unknown JAXB exception; nested exception is com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions 
@XmlAttribute/@XmlValue need to reference a Java type that maps to text in XML. 
    this problem is related to the following location: 
     at protected javax.xml.datatype.XMLGregorianCalendar com.example.schema.DateTimeWithTimeZone.dateTime 
     at com.example.schema.DateTimeWithTimeZone 
    ... 

生成的Java文件如下：

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "DateTimeWithTimeZone") 
public class DateTimeWithTimeZone { 

    @XmlAttribute(name = "DateTime", required = true) 
    @XmlSchemaType(name = "dateTime") 
    protected XMLGregorianCalendar dateTime; 
    @XmlAttribute(name = "TimeZone") 
    protected String timeZone; 

    public XMLGregorianCalendar getDateTime() { 
     return dateTime; 
    } 
    public void setDateTime(XMLGregorianCalendar value) { 
     this.dateTime = value; 
    } 
    public String getTimeZone() { 
     if (timeZone == null) { 
      return "UTC"; 
     } else { 
      return timeZone; 
     } 
    } 
    public void setTimeZone(String value) { 
     this.timeZone = value; 
    } 
} 

我该如何摆脱这个异常？

Answer 1

嗯，这似乎很奇怪。我找不到一个很好的理由，为什么这不起作用。您是否尝试过使用自定义绑定文件将xs：datetime转换为使用Java Calendar对象？它似乎在某种程度上打破了XmlGregorianCalendar。也许正常Calendar将工作。

这个文件看起来是这样的：

<bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <globalBindings> 
    <javaType name="java.util.Calendar" xmlType="xs:dateTime" 
     parseMethod="javax.xml.bind.DatatypeConverter.parseDate" 
     printMethod="javax.xml.bind.DatatypeConverter.printDate" 
    /> 
    </globalBindings> 
</bindings> 

您可以添加到您的pom.xml这样的：

<configuration> 
    <bindingFiles>/path/to/bindings.xjb</bindingFiles> 
<configuration> 

或使用XJC像：

xjc schema.xsd -b bindings.xjb
