你能从JAX-WS @WebMethod返回一个数组吗？ [英] Can you return an array from a JAX-WS @WebMethod?

问题描述

我很确定你可以，但除了回答标题中的问题之外，你能否解释一下这些问题的优点，缺点，警告（如果有的话）？我知道你不能从WebMethod（这是愚蠢的，IMO，但我不知道设计原因是什么，我应该拒绝判断）返回List，Set，Collection，Map或任何接口。

I'm pretty sure you can, but in addition to answering the question in the title, could you also explain the pros, cons, caveats, if any, to doing so? I know that you can't return a List, Set, Collection, Map, or any interface, from a WebMethod (which is stupid, IMO, but I don't know what the design reasons were should I should probably withhold judgment).

感谢您的任何建议。

推荐答案

你可以返回数组，我发现它们很有用。

You can return arrays, and I have found them useful.

收集的主要原因是问题是某些语言（例如C）不理解集合的概念，因此，为了保持可移植性，您需要确保传递可以用大多数语言表示的结构。

The main reason that collections are a problem is that some languages, such as C, doesn't understand the concept of a collection, so, to remain portable you need to make certain to pass structures that can be represented in the majority of languages.

此外，我从不擅长传递集合，因为来自Web服务的内容应该是相当静态的。如果要添加它，则将数组转换为集合，然后将数组传递回Web服务以进行更改。

Besides,I am never a fan of passing collections, as, what comes from the webservice should be fairly static. If you want to add to it, then convert the array to a collection, then pass back an array to the webservice to make changes.
