我在这里有一些@ javax.xml.bind.annotation.Xml …注释类用于RESt Web服务. Jersey是在一个 Spring托管的Web容器中设置的,Web服务正在返回格式良好的xml.我们使用maven-enunciate-plugin来记录Web服务并为返
1)创建了一个JaxbFactory,它配置并返回一个自定义编组器(和unmarshaller,BTW).我省略下面的getter /和解组设置……
//constructor public JaxbFactory() throws Exception { context = JAXBContext.newInstance(ResourceDto.class); // Setup the marshaller marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, XmlMetadataConstants.XML_SCHEMA_LOCATION); // this schema location is used in generating the schema-location property in the xml }
2)泽西岛的“工厂级”不是“可见的”.为了使它可见,我创建了一个MarshallerProvider.看起来像这样:
@Provider public class ResourceJaxbMarshallerProvider implements ContextResolver<Marshaller> { // injected by Spring private ResourceJaxbFactory ResourceJaxbFactory; private ResourceStatusJaxbFactory ResourceStatusJaxbFactory; /* * ---------------------------------------- * Setters (for Spring injected properties) * ---------------------------------------- */ public void setResourceJaxbFactory(ResourceJaxbFactory ResourceJaxbFactory) { this.ResourceJaxbFactory = ResourceJaxbFactory; } public void setResourceStatusJaxbFactory(ResourceStatusJaxbFactory ResourceStatusJaxbFactory) { this.ResourceStatusJaxbFactory = ResourceStatusJaxbFactory; } /* * ------------------------ * Interface Implementation * ------------------------ */ public Marshaller getContext(Class<?> type) { if (type == ResourceDto.class) return ResourceJaxbFactory.getMarshaller(); else if (type == ResourceStatusDto.class) return ResourceStatusJaxbFactory.getMarshaller(); else return null; } }
我使用Jersey / Spring Servlet将Jersey连接到Spring,因此任何由Spring创建的@Provider类都会被Jersey自动识别.在我的Spring applicationContext.xml中,我所要做的就是实例化资源提供者.反过来,它会从工厂中抓住编组员.
3)我发现关键的另一件事是我必须在包含我的资源的根包中创建一个package-info.java文件.看起来像这样:
/* * Note that this file is critical for ensuring that our ResourceDto object is * marshalled/unmarshalled with the correct namespace. Without this, marshalled * classes produce XML files without a namespace identifier */ @XmlSchema(namespace = XmlMetadataConstants.XML_SCHEMA_NAMESPACE, elementFormDefault = XmlNsForm.QUALIFIED) package com.yourcompany.resource; import javax.xml.bind.annotation.XmlNsForm;
至少我认为这是我需要做的一切,我不记得每件作品.我确实记得,package-info.java是最后一个让它全部融合在一起的关键因素.
希望有所帮助.我花了太多时间来挖掘所有这些信息.在我希望它进行适当的xml架构验证(以及架构无效输入的正确错误报告)之前,Jersey很诱人.一旦我开始沿着这条路开始,泽西从脑死亡变得容易到相当困难.大多数困难是从网上各种帖子中删除所有细节.希望这将有助于您更快,更快.
