如何编写JAX-WS服务，使@WebMethod的@WebParam成为类似DateTime的Joda时间类？参数上的@XmlTypeAdapter是否有效？我正在部署GlassFish 2.1

让我澄清这个问题，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JAXB类上，这是相关的，但不是我要问的问题。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
    );

}

首先编写简单的转换器（在本例中为日历，但可以轻松更改为Joda Time）：

接下来，您必须将转换器引入JAXB（

xjb

file）：

其中，

Adapter2.class

是一个生成的适配器，用于封装POJO转换器。如您所见，使用了

Calendar

而不是笨拙的

javax.xml.datatype.xmlgoriiancalendar

。如果您将此示例调整为Joda Time，请与我们共享。

请遵循上面的解决方案模板

1.）创建一个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());
  }

}

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>


...
....

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

注意：当我试图向类中的unmarshal方法传递一个适当的XmlGregorianCalendar对象时，我得到了JaxB编译器错误，它说它需要类型字符串，而不是XmlGregorianCalendar。使用字符串进行测试，它似乎工作正常。这里的错误处理又快又脏，所以请随意修复

希望这有帮助

Maven pom插件代码段：

       <plugin>
          <groupId>org.jvnet.jaxb2.maven2</groupId>
          <artifactId>maven-jaxb2-plugin</artifactId>
          <configuration>
              <schemaDirectory>src/main/resources/schemas/</schemaDirectory>

          <bindingIncludes>
            <bindingInclude>jaxb-custom-bindings.xml</bindingInclude>
          </bindingIncludes>
          </configuration>
          <executions>
            <execution>
              <goals>
                <goal>generate</goal>
              </goals>
            </execution>
          </executions>
        </plugin>

}

您必须直接对参数进行注释，如下所示（我使用@DennisTemper编写的XSDDateTimeMarshaller作为您问题的答案之一，但请随意替换为另一个…：

因为我是用JAXB注释手工编写Java类的，所以我假设在相反的方向上不存在任何问题，同时跳过xjb文件？还有一点，您重复了很容易找到的映射JAXB类字段的示例，但我的问题是关于通过JAX-WS注释作为SOAP服务公开的方法的参数。您是否有过JAXB类型在该上下文中适应的经验或示例？请查看我更新的问题，我认为我在最初编写时措辞不正确。感谢您的尝试，但我正在寻找问题的答案，如前所述，这是一个可以接受Joda DateTime对象作为（at）的（at）Web服务标签放错地方了，至少今天的maven插件是这样。检查工作示例。它位于内部，但多行xml不适用于注释。

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

      return new DateTime(date.getTime());
  }

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

}
