JAX-RS:每个资源的选项 [英] JAX-RS: OPTIONS for every Resource

问题描述

我正在将JAX-RS接口与XMLHttpRequest(XHR)一起使用.由于XHR预检，XHR在调用实际资源之前总是发送OPTIONS.

I am using a JAX-RS interface with XMLHttpRequest (XHR). Due to the XHR preflight, XHR send always OPTIONS before calling the real resource.

现在，我有数十种方法，每一次重新配置都需要OPTIONS.有什么办法可以自动执行此操作?我不想编写许多方法，例如:

Now I have dozens of methods and I need the OPTIONS for every resoruce. Is there any way to do this automatically? I dont want to write dozens of methods like:

@OPTIONS
@Path("/{id}")
@PermitAll
public Response optionsById() {
    return Response.status(Response.Status.NO_CONTENT).build();
}

@OPTIONS
@Path("/{id}/data")
@PermitAll
public Response optionsByData() {
    return Response.status(Response.Status.NO_CONTENT).build();
}

推荐答案

更新2013年9月12日:无效.使用所有这些@ GET/@ DELETE/@ POST/@ PUT不再起作用.

最后，我解决了我的问题.我创建了一个超类OptionsResource，所有资源都从该超类继承.此资源包含:

Finally I solved my problem. I created a super class OptionsResource, from which all resources inherit. This resoruce contains:

// Match root-resources
@OPTIONS
@PermitAll
public Response options() {
    return Response.status(Response.Status.NO_CONTENT).build();
}

// Match sub-resources
@OPTIONS
@Path("{path:.*}")
@PermitAll
public Response optionsAll(@PathParam("path") String path) {
    return Response.status(Response.Status.NO_CONTENT).build();
}

一个例子:

@Path("/test")
public class TestResource extends OptionsResource {

    @GET
    @Produces("text/plain;charset=UTF-8")
    public Response index() {
        return Response.status(Status.OK).entity("works").build();
    }

}

此匹配项:

• curl -I -X选项 http://myhost.com/test
• 卷曲-I -X选项 http://myhost.com/test/asd/aasd /12/
• 等

• curl -I -X OPTIONS http://myhost.com/test
• curl -I -X OPTIONS http://myhost.com/test/asd/aasd/12/
• etc.
