JAX-WS和Joda-Time？

如何编写JAX-WS服务，以便@WebMethod的@WebParam是像DateTime这样的Joda-Time类？参数上的@XmlTypeAdapter会起作用吗？我正在部署到GlassFish 2.1。

让我澄清一下这个问题，因为到目前为止这两个答案都集中在将自定义类型绑定到现有的JAXB类上，这与我要问的问题有关。如何使以下@WebService接受joda DateTime对象作为参数？

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import org.joda.time.DateTime;

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface Resender {
    @WebMethod
    void resend(
            @WebParam(name = "start") DateTime start,
            @WebParam(name = "end") DateTime end
    );

}

首先编写简单转换器（在此示例中为Calendar，但可以轻松更改为Joda-Time）：

public class XsdDateTimeConverter {

    public static Calendar unmarshal(String dateTime) {
        final GregorianCalendar calendar = new GregorianCalendar();
        calendar.setTime(DatatypeConverter.parseDate(dateTime).getTime());
        return calendar;
    }

    public static String marshal(Calendar calendar) {
        return DatatypeConverter.printDate(calendar);
    }

}

接下来，您必须将转换器引入JAXB（xjb文件）：

<globalBindings>

    <javaType
            name="java.util.Calendar"
            xmlType="xs:dateTime"
            parseMethod="XsdDateTimeConverter.unmarshal"
            printMethod="XsdDateTimeConverter.marshal"
            />
    <javaType
            name="java.util.Calendar"
            xmlType="xs:date"
            parseMethod="XsdDateTimeConverter.unmarshal"
            printMethod="XsdDateTimeConverter.marshal"
            />
</globalBindings>

在生成的JAXB模型中，xjc生成了以下注释：

@XmlJavaTypeAdapter(Adapter2.class)
@XmlSchemaType(name = "date")
protected Calendar date;

其中Adapter2.class是包装POJO转换器的生成适配器。如您所见，Calendar被用来代替笨拙的javax.xml.datatype.XMLGregorianCalendar。如果您将此示例调整为Joda-Time，请与我们分享。

以上解决方案模板

1。）创建XSML适配器

import java.util.Date;

import javax.xml.bind.annotation.XmlTransient;
import javax.xml.bind.annotation.adapters.XmlAdapter;

import org.joda.time.DateTime;

@XmlTransient
public class XSDDateTimeMarshaller extends XmlAdapter<Date, DateTime> {

  @Override
  public DateTime unmarshal(Date date) throws Exception {
      return new DateTime(date.getTime());
  }

  @Override
  public Date marshal(DateTime dateTime) throws Exception {
      return new Date(dateTime.getMillis());
  }

}

2。）使用（来自实体类的snipet）注释jodatime属性：

...

@XmlRootElement(name="MyEntity", namespace="http://www.mycompany.com/module")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder={"...", "...", "timeStamp", "...", "..."})
public class MyEntity

...    

   @XmlElement(namespace="http://www.mysite.com/module")
   @XmlJavaTypeAdapter(XSDDateTimeMarshaller.class)

   @NotNull
   @Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
   @Column(name="TIME_STAMP")
   private DateTime timeStamp;

...

}

3.。）将类型绑定添加到myentity.xsd 

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3.org/2001/XMLSchema http://www.w3.org/2001/XMLSchema.xsd"
targetNamespace="http://www.mysite.com/module"
xmlns:tns="http://www.mysite.com/module"
attributeFormDefault="unqualified"
elementFormDefault="qualified"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jaxb:extensionBindingPrefixes="xjc"
jaxb:version="2.1">
<xsd:annotation>
    <xsd:appinfo>
        <jaxb:globalBindings>
            <jaxb:javaType name="org.joda.time.DateTime"
                xmlType="xsd:dateTime"
                parseMethod="com.mycompany.myproduct.marshaller.XSDDateTimeMarshaller.unmarshal"
                printMethod="com.mycompany.myproduct.marshaller.XSDDateTimeMarshaller.marshal"/>
            <jaxb:javaType name="org.joda.time.DateTime"
                xmlType="tns:date"
                parseMethod="com.mycompany.myproduct.marshaller.XSDDateTimeMarshaller.unmarshal"
                printMethod="com.mycompany.myproduct.marshaller.XSDDateTimeMarshaller.marshal"/>
        </jaxb:globalBindings>
    </xsd:appinfo>
</xsd:annotation>

<xsd:element name="MyEntity" type="tns:MyEntity"/>

<xsd:complexType name="MyEntity">
         <xsd:sequence>
            ...
            <xsd:element name="timeStamp" type="tns:date"/>
            ....
    </xsd:sequence>
</xsd:complexType>

<xsd:simpleType name="date">
    <xsd:restriction base="xsd:dateTime" />
</xsd:simpleType>

</xsd:schema>

您必须直接注释参数，例如下面的内容（我正在使用@DennisTemper编写的XSDDateTimeMarshaller作为您问题的答案之一，但可以替换为另一个......）：

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface Resender {
    @WebMethod
    void resend(
        @WebParam(name = "start") @XmlJavaTypeAdapter(type = DateTime.class, value = XSDDateTimeMarshaller.class) DateTime start,
        @WebParam(name = "end") @XmlJavaTypeAdapter(type = DateTime.class, value = XSDDateTimeMarshaller.class) DateTime end
    );
}

答案 3 :(得分：1)

这是一个非注释Joda解决方案。我们已经从xsd生成了对象，并希望它们使用Joda而不是XmlGregorianCalendar。

注意：当我尝试将正确的XmlGregorianCalendar对象传递给类中的unmarshal方法时，我得到了JaxB编译器错误，表示它需要类型String，而不是XmlGregorianCalendar。用String测试，它似乎工作正常。这里处理快速而肮脏的错误，所以请随意修复。

希望这有帮助。
