GlassFish 3.1.2充满了MOXy（EclipseLink JAXB）

我非常高兴地宣布， EclipseLink JAXB（MOXy）现在是GlassFish 3.1.2中的JAXB（ JSR-222 ）提供程序。我要感谢EclipseLink和GlassFish提交者为实现这一目标付出的辛勤工作。

在本文中，我将介绍如何利用MOXy创建JAX-WS服务。在以后的文章中，我将更详细地介绍更多扩展。

网络服务（JAX-WS）

对于这篇文章，我们将实现一个简单的服务，该服务通过ID查找客户。由于这只是“ Hello World”类型的示例，因此该服务将始终返回名称为“ Jane Doe”的客户。

package blog.jaxws.service;import javax.jws.*;
import blog.jaxws.model.Customer;@WebService
public class FindCustomer {@WebMethodpublic Customer findCustomer(int id) {Customer customer = new Customer();customer.setId(id);customer.setFirstName("Jane");customer.setLastName("Doe");return customer;}}

WEB-INF / sun-jaxws.xml

有多种方法可以将MOXy指定为JAXB提供程序。我的偏好是使用位于WEB-INF目录中的sun-jaxws.xml文件。

<?xml version="1.0" encoding="UTF-8"?>
<endpointsxmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"version="2.0"><endpointname='FindCustomer'implementation='blog.jaxws.service.FindCustomer'url-pattern='/FindCustomerService'databinding='eclipselink.jaxb'/>
</endpoints>

模型

当MOXy被指定为JAXB提供程序时，我们可以利用其所有映射扩展。在此示例中，我们将使用@XmlPath进行基于XPath的映射。

package blog.jaxws.model;import javax.xml.bind.annotation.*;
import org.eclipse.persistence.oxm.annotations.XmlPath;@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder={"firstName", "lastName"})
public class Customer {@XmlAttributeprivate int id;@XmlPath("personal-info/first-name/text()")private String firstName;@XmlPath("personal-info/last-name/text()")private String lastName;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getFirstName() {return firstName;}public void setFirstName(String firstName) {this.firstName = firstName;}public String getLastName() {return lastName;}public void setLastName(String lastName) {this.lastName = lastName;}}

WSDL

以下是为此服务生成的WSDL：

</definitions>

XML模式

下面是为该模型生成的WSDL引用的XML模式。请注意，它如何包含@XmlPath批注中指定的“个人信息”元素。

<?xml version="1.0" encoding="UTF-8"?>
<!-- Published by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is Metro/2.2-b13 (branches/2.2-6964; 2012-01-09T18:04:18+0000) JAXWS-RI/2.2.6-promoted-b20 JAXWS/2.2 svn-revision#unknown. -->

</xsd:schema>

服务请求

以下是对我们服务的要求：

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Header/><S:Body><ns2:findCustomer xmlns:ns2="http://service.jaxws.blog/"><arg0>123</arg0></ns2:findCustomer></S:Body>
</S:Envelope>

服务回应

响应利用了我们在Customer类上使用的@XmlPath批注，将firstName和lastName属性映射到XML。

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns0:findCustomerResponse xmlns:ns0="http://service.jaxws.blog/"><return id="123"><personal-info><first-name>Jane</first-name><last-name>Doe</last-name></personal-info></return></ns0:findCustomerResponse></S:Body>
</S:Envelope>
