无法从 JAX-WS Web 服务返回集合或数组

我发现我无法从 JAX-WS Web 服务返回集合。

我意识到 Java Collections API 可能并不被所有客户端支持，所以我转而返回一个数组，但我似乎也无法做到这一点。

我的 Web 服务设置如下：

@WebService
public class MyClass {
  public ReturnClass[] getArrayOfStuff() {
    // extremely complex business logic... or not
    return new ReturnClass[] {new ReturnClass(), new ReturnClass()};
  }
}

ReturnClass 只是一个 POJO。我创建了另一个返回单个实例的方法，并且该方法有效。当我使用集合/数组时，这似乎是一个问题。

当我部署该服务时，在使用它时出现以下异常：

javax.xml.bind.MarshalException - 带有链接异常： [javax.xml.bind.JAXBException：[LReturnClass；在此上下文中未知]

我是否需要以某种方式注释 ReturnClass 类以使 JAX-WS 意识到它？还是我做错了什么？

原文

I found that I was unable to return collections from my JAX-WS Web Service.

I appreciate that the Java Collections API may not be supported by all clients, so I switched to return an array, but I can't seem to do this either.

I've set up my web service as follows:

@WebService
public class MyClass {
  public ReturnClass[] getArrayOfStuff() {
    // extremely complex business logic... or not
    return new ReturnClass[] {new ReturnClass(), new ReturnClass()};
  }
}

And the ReturnClass is just a POJO. I created another method that returns a single instance, and that works. It just seems to be a problem when I use collections/arrays.

When I deploy the service, I get the following exception when I use it:

javax.xml.bind.MarshalException - with linked exception: [javax.xml.bind.JAXBException: [LReturnClass; is not known to this context]

Do I need to annotate the ReturnClass class somehow to make JAX-WS aware of it?
Or have I done something else wrong?

我不确定这是否是正确的方法，但在一种情况下，我想返回一个集合，我将集合包装在另一个类中：

@WebService
public class MyClass {
    public CollectionOfStuff getArrayOfStuff() {
        return new CollectionOfStuff(new ReturnClass(), new ReturnClass());
    }
}

然后：

public class CollectionOfStuff {
   // Stuff here
   private List<ReturnClass> = new ArrayList<ReturnClass>();
   public CollectionOfStuff(ReturnClass... args) {
       // ...
   }
}

免责声明：我面前没有实际的代码，所以我想我的示例缺少一些注释等，但这就是要点。

I am unsure of wheter this is the correct way to do it, but in one case where I wanted to return a collection I wrapped the collection inside another class:

@WebService
public class MyClass {
    public CollectionOfStuff getArrayOfStuff() {
        return new CollectionOfStuff(new ReturnClass(), new ReturnClass());
    }
}

And then:

public class CollectionOfStuff {
   // Stuff here
   private List<ReturnClass> = new ArrayList<ReturnClass>();
   public CollectionOfStuff(ReturnClass... args) {
       // ...
   }
}

Disclaimer: I don't have the actual code in front of me, so I guess my example lacks some annotations or the like, but that's the gist of it.
