JAX-RS 2.0：如何注册Feature或ContextResolver以在Mapper中注册自定义JaxbAnnotationIntrospector内省 [英] JAX-RS 2.0: How to register a Feature or a ContextResolver to have a custom JaxbAnnotationIntrospector introspection registered in the Mapper

问题描述

我已经在我的JAX-RS 2.0应用程序中正确注册了JacksonJaxbJsonProvider：

I have correctly registered JacksonJaxbJsonProvider in my JAX-RS 2.0 application using:

    public Set<Class<?>> getClasses() {
... classes.add(com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider.class);
}

现在我需要自定义它在JAX-RS资源中自己使用的Mapper因为我需要添加SerializationFeature.FAIL_ON_EMPTY_BEANS。

Now I need to customise the Mapper it self used in the JAX-RS resources because I need to add SerializationFeature.FAIL_ON_EMPTY_BEANS.

我已经看到了如何使用功能或自定义Contextresolver执行此操作的示例，但我知道如何将其添加到Mapper我在我的源代码中创建但我不能将它添加到REST服务使用的Mapper中：

I have seen examples of how to do this using a Feature or a custom Contextresolver, but I know how to add it to a Mapper I create in my source code but I cannot add it to the Mapper that the REST services use using:

classes.add(ObjectMapperContextResolver.class);

classes.add(MarshallingFeature.class);

因为JAX-RS 2.0应用程序忽略了这些类。

Because the JAX-RS 2.0 app ignores those classes.

如何在我的JAX-RS应用程序中添加Feature或ContextResolver以便识别它们？

How can I add the Feature or ContextResolver in my JAX-RS application so they are recognised?

推荐答案

你可以重用Jersey实现自定义应用程序。 更多信息使用ContextResolver获取要使用的自定义ObjectMapper。

You could reuse the Jersey implementation custom application. More Info And using ContextResolver get the custom ObjectMapper to use.

示例：

public class MyApplication extends ResourceConfig {
   public MyApplication() {
      /* packages that contains JAX-RS components, registers them to use also */
      packages("org.foo.rest;org.bar.rest");
      /* here register the provider */
      register(MapperProvider.class);
 }

}

MapperProvider类。

The MapperProvider Class.

@Provider
public class MapperProvider implements ContextResolver<ObjectMapper> {

@Override
public ObjectMapper getContext(Class<?> arg0) {
   /* you can configure the mapper as you like */
   return new ObjectMapper()
            .registerModule(new JaxbAnnotationModule()
            .configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false));
}
