我正在尝试在 Wildfly 8 上设置一个 REST 服务，该服务返回带有自定义枚举值的 JSON。我知道 Wildfy 使用 Jackson 2.3 进行序列化。我也知道，当使用 Jackson ObjectMapper 注册 JaxbAnnotationModule 时，序列化程序会产生正确的结果。问题是，我如何配置我的 Wildfly 实例或我的 web 项目来使用这个模块。
好的，为了更清楚，一个简单的例子。
首先，这可以正常工作并生成我需要的结果。
@XmlEnum
public enum TestEnum
@XmlEnumValue("2")
TWO;
}
public class Test {
public static void main(String[] args) {
ObjectMapper mapper = new ObjectMapper();
JaxbAnnotationModule jaxbModule = new JaxbAnnotationModule();
mapper.registerModule(jaxbModule);
try {
mapper.writeValue(System.out, TestEnum.TWO);
} catch (Exception e) {
}
}
这会产生正确的输出:“2”
现在，我的问题服务
@Path("test")
@RequestScoped
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public class TestRestService {
@GET
@Path("/json")
@Produces({MediaType.APPLICATION_JSON})
public TestEnum testJson() {
return TestEnum.TWO;
}
}
这将返回“TWO”，这不是我想要的。
我没有在“jboss-deployment-structure.xml”和“web.xml”中配置任何东西。
我没有使用 maven，所以除了为我指明方向之外，任何 pom.xml 解决方案都对我不起作用。
我阅读了文档 here但找不到启用 JaxbAnnotationModule 的选项。
任何自定义适用于 JSON 和 XML 的枚举值的可能性都将受到重视。
- - - 更新 - - -
理论上，解决方案已经发布 here
如果我使用该解决方案，请尝试将 Jackson Mapper 与 JaxbAnnotationModule 一起使用，它应该会创建正确的输出。
@Provider
@Produces(MediaType.APPLICATION_JSON)
public class JacksonMapper implements MessageBodyWriter<Object> {
ObjectMapper mapper;
@PostConstruct
void init() {
mapper = new ObjectMapper();
JaxbAnnotationModule jaxbModule = new JaxbAnnotationModule();
// this is what is causing the current problem
mapper.registerModule(jaxbModule);
}
@Override
public boolean isWriteable(Class<?> aClass, Type type,
Annotation[] annotations, MediaType mediaType) {
return true;
}
@Override
public long getSize(Object object, Class<?> aClass, Type type,
Annotation[] annotations, MediaType mediaType) {
return 0;
}
@Override
public void writeTo(Object object, Class<?> aClass, Type type,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> stringObjectMultivaluedMap,
OutputStream outputStream) throws IOException,
WebApplicationException {
mapper.writeValue(outputStream, object);
}
}
在我的 jboss-deployment-structure.xml 中，我激活了必要的模块(或者我认为)
<dependencies>
<module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import" />
<module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
</dependencies>
当调用我的测试方法时，我在 javax.xml.bind.annotation.XmlElement 上得到了一个 ClassNotFound 异常，应该通过包含 来包含它。 “com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider”因为这取决于 “javax.ws.rs.api”然后包括 "javax.xml.bind.api"其中包含缺失的类。
如果我没有将创建的 jaxbModule 注册到映射器，除了注释 @XmlEnumValue 被忽略之外，一切正常。我得到与没有更改时相同的输出。
有什么建议么？

OP发布了他的解决方案:
事实证明，模块描述必须手动更新，如 here 所述。即使该类应该被引用。
解决方案:
更新文件:wildfly-8.0.0.CR1\modules\system\layers\base\com\fasterxml\jackson\jaxrs\jackson-jaxrs-json-provider\main\module.xml
<module xmlns="urn:jboss:module:1.1" name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider">
<resources>
<resource-root path="jackson-jaxrs-json-provider-2.2.3.jar"/>
<resource-root path="jackson-jaxrs-base-2.2.3.jar"/>
<resource-root path="jackson-module-jaxb-annotations-2.2.3.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.ws.rs.api"/>
<!-- Add this line -->
<module name="javax.xml.bind.api" />
<module name="com.fasterxml.jackson.core.jackson-annotations"/>
<module name="com.fasterxml.jackson.core.jackson-core"/>
<module name="com.fasterxml.jackson.core.jackson-databind"/>
</dependencies>
</module>
