如何配置Glassfish 5以使用Moxy作为默认提供程序？

Question

我正在将我们的Web应用程序从Glassfish 3迁移到Glassfish 5，在迁移过程中，我遇到了这个请求错误。

Glassfish 5似乎正在使用JSON-B序列化。Glassfish 5忽略JAXB@XmlJavaTypeAdapter注释？

在过去，我们使用moxy和jaxb进行json绑定，因此我一直在尝试将moxy注册为Glassfish 5中的默认提供程序。我按照这里的指示做了，运气不好。

https://howtodoinjava.com/jersey/jax-rs-jersey-moxy-json-example/

我还阅读了Glassfish 5文档，但没有找到任何注册默认提供者的类似示例。如果有人能解释一下我在配置中做错了什么，我们将不胜感激。我在下面提供了我的配置示例。

如何配置Glassfish 5以使用Moxy作为默认提供程序？

笔记：

• 启动glassfish时，我已经调试了JsonServicesContextResolver。java类并验证了构造函数和getContext方法在初始化过程中被命中

JsonServicesContextResolver.java

package com.lnka.eng.grid.jersey;

import org.eclipse.persistence.jaxb.JAXBContextProperties;
import org.glassfish.jersey.moxy.json.MoxyJsonConfig;

import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class JsonServicesContextResolver
    implements ContextResolver<MoxyJsonConfig>
{
  private MoxyJsonConfig config;

  public JsonServicesContextResolver()
  {
    config = new MoxyJsonConfig()
        .setNamespaceSeparator(':')
        .setAttributePrefix("")
        .setValueWrapper("value")
        .property(JAXBContextProperties.JSON_WRAPPER_AS_ARRAY_NAME, true)
        .setFormattedOutput(true)
        .setIncludeRoot(true)
        .setMarshalEmptyCollections(true);
  }

  @Override
  public MoxyJsonConfig getContext(Class<?> objectType)
  {
    return config;
  }
}

程序控制器。JAVA

package com.lnka.eng.view.controller;

@Path("/mgmt/programs/")
@Stateless
@Transactional(Transactional.TxType.NOT_SUPPORTED)
public class ProgramsController extends Controller
{
 @GET
  @Path("/list/")
  @Produces(MediaType.APPLICATION_JSON)
  public Response getProgramsList()
  {
    List<Program> programs = getPrograms();

    return Response.ok(programs).build();    
  }
}

网格应用程序。JAVA

package com.lnka.eng.grid.jersey;

import com.lnka.eng.view.controller.ProgramsController;

import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

public class GridApplication extends Application
{
  //Add Service APIs
  @Override
  public Set<Class<?>> getClasses()
  {
    Set<Class<?>> resources = new HashSet<Class<?>>();

    //register REST modules
    resources.add(ProgramsController.class);

    //Manually adding MOXyJSONFeature
    resources.add(org.glassfish.jersey.moxy.json.MoxyJsonFeature.class);

    //Configure Moxy behavior
    resources.add(JsonServicesContextResolver.class);

    return resources;
  }
}

网状物xml

我已经删除了这个文件中一些我认为不相关的配置（安全性、ejb配置等）

Answer 1

问题是我们需要更新web.xml以将MoxyConfig包含在会话配置范围中。我还缺少我们的一个侦听器的一些配置，但相关代码如下。

以下内容放置在每个

<init-param>
      <param-name>jersey.config.server.jsonFeature</param-name>
      <param-value>MoxyJsonFeature</param-value>
</init-param>
