jersey - 是否可以在JSON-B（Yasson）中全局设置默认日期格式，而不是在每个属性上添加注释？(Is it possible to set the default date format in JSON-B (Yasson) globally, instead of adding an annotation on every property?)

Question

I have using Jersey so far and I am doing my first implementation with JSON-B.

(到目前为止，我已经使用Jersey，并且正在使用JSON-B进行第一个实现。)

I am using Payara, so I working with Jersey and Yasson.

(我正在使用Payara，所以我与Jersey和Yasson合作。)

I had an issue, because the serialized dates would always contain the "[UTC]" suffix.

(我遇到了一个问题，因为序列化的日期将始终包含“ [UTC]”后缀。)

I have managed to use an annotation on my date property, in my DTO.

(我设法在DTO的date属性上使用了注释。)

But I would like to configure that globally (in the JAX-RS application config?), instead of repeating myself on every date property.

(但是我想全局配置（在JAX-RS应用程序配置中？），而不是在每个date属性上重复我自己。)

Is that possible?

(那可能吗？)

I haven't found anything so far...

(到目前为止我还没有发现任何东西...)

Side question: I assume that it is possible to get rid of this "[UTC]" suffix, since it breaks all clients trying to parse the date.

(附带的问题：我认为有可能摆脱此“ [UTC]”后缀，因为它会使尝试解析日期的所有客户端中断。)

Any idea?

(任何的想法？)

Thanks to this Github issue , I was able to solve my problem.

(由于这个Github问题 ，我得以解决我的问题。)

Here is what I ended up writing in my code:

(这是我最终在代码中编写的内容：)

JSONConfigurator.java:

import javax.json.bind.Jsonb;
import javax.json.bind.JsonbBuilder;
import javax.json.bind.JsonbConfig;
import javax.json.bind.config.PropertyNamingStrategy;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class JSONConfigurator implements ContextResolver<Jsonb> {

  @Override
  public Jsonb getContext(Class<?> type) {
    JsonbConfig config = getJsonbConfig();
    return JsonbBuilder
      .newBuilder()
      .withConfig(config)
      .build();
  }

  private JsonbConfig getJsonbConfig() {
    return new JsonbConfig()
      .withDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX", null);
  }
}

And:

(和：)

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

@ApplicationPath("/api")    
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new HashSet<Class<?>>();
        addRestResourceClasses(resources);
        resources.add(JSONConfigurator.class);
        return resources;
    }


    private void addRestResourceClasses(Set<Class<?>> resources) {
      ...
    }

}
