CXF：警告：找不到消息类编写器的响应类ArrayList [英] CXF: WARNING: No message body writer has been found for response class ArrayList

问题描述

我遇到以下错误：

WARNING: No message body writer has been found for response class ArrayList.

在以下代码上：

    @GET
    @Consumes("application/json")
    public List getBridges() {
        return  new ArrayList(bridges);
    }

我知道CXF可以处理这种情况，因为我以前已经做过-在后台定义了CXF和相关Maven工件的平台（即我不知道它是如何完成的。）

I know it's possible for CXF to handle this case because I've done it before - with a platform that defined the CXF and related maven artifacts behind the scenes (i.e. I didn't know how it was done).

问题：如何在不添加XML绑定或其他源代码修改的情况下使CXF支持此操作？

So, the question: how can I get CXF to support this without adding XML bindings or other source code modifications?

请注意以下答案也是如此XML绑定问题，这对我的情况不令人满意：
未找到响应类ArrayList的消息正文编写者

Note the following answer addressed the same problem with XML bindings, which is not satisfactory for my case: No message body writer has been found for response class ArrayList

推荐答案

只是一个简单的缺少Accept标头：

The problem turns out to be a simple missing Accept header:

Accept: application/json

将其添加到请求中即可解决问题。

Adding this to the request resolves the problem.
