如何解决EclipseLink(MOXy)的“获取属性“ eclipselink.oxm.metadata-source”不支持'? [英] How do I solve EclipseLink's (MOXy) 'getting property "eclipselink.oxm.metadata-source" is not supported'?
问题描述
主要根据EclipseLink网站上的教程,我整理了以下代码:
I've got the following piece of code which I've put together mainly based on tutorials on EclipseLink's website:
Partner p = new Partner();
p.setId(1);
p.setKey("a");
p.setName("this is the name");
Map<String, Source> metadataSourceMap = new HashMap<String, Source>();
metadataSourceMap.put("com.company.pas.entity.partner", new StreamSource("/com/company/pas/entity/mapping/partner-pojo2xml.xml"));
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, metadataSourceMap);
JAXBContext jaxbContext = JAXBContext.newInstance(new Class[] {Partner.class}, properties);
当我尝试运行这段代码时,我得到的只是一个例外:
When I try to run this piece of code, all I get is an exception:
Exception in thread "main" javax.xml.bind.JAXBException: property "eclipselink.oxm.metadata-source" is not supported
at com.sun.xml.internal.bind.v2.ContextFactory.createContext(ContextFactory.java:115)

at javax.xml.bind.ContextFinder.find(ContextFinder.java:445)
at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:637)
我还没有在此处包括映射文件(partner-pojo2xml.xml),因为无论是否将映射文件添加到 metaDataSourceMap
,都会发生异常。
I haven't included the "mapping file" (partner-pojo2xml.xml) here, as the exception occurs regardless of whether the mapping file is added to the metaDataSourceMap
or not.
可从下面找到pom.xml中的相关部分。
The relevant part from pom.xml can be found below.
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.5.1</version>
</dependency>
我在做什么错?我尝试了太多组合,但我无法使其运行。
What am I doing wrong? I've tried too many combinations, but I just can't get it to run.
推荐答案
您需要确保自己有一个 jaxb.properties
文件,其中包含以下条目:
You need to be sure you have a jaxb.properties
file with the following entry:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
使用时该文件必须位于与用于引导 JAXBContext
的类的包名称匹配的目录结构中。该结构需要放在 src / main / resources
文件夹下。以下是我在GitHub中的示例的链接:
When you are using Maven this file needs to be in a directory structure matching the package name of the classes used to bootstrap the JAXBContext
. This structure needs to go under the src/main/resources
folder. Below is a link to an example I have in GitHub:
