骆驼JAX-RS和跨域请求 [英] Camel JAX-RS and Cross Domain Request

问题描述

我希望能够做到在我的本地骆驼例如HTTP请求（只为发展宗旨，我知道这是不好的做法）。现在，我坚持了：

I'd like to be able to do HTTP requests on my localhost Camel instance (just for development purpose, I know this is bad practice). For now, I'm stuck with :

 Origin http://localhost:8000 is not allowed by Access-Control-Allow-Origin.

我搜索我怎么能告诉骆驼允许这样的请求，但没有找到答案。我使用骆驼CXF和rsServer创建我的终点。

I've search how can I tell Camel to allow such requests, but didn't find an answer. I'm using camel-cxf and the rsServer to create my endpoint.

我有一个端点看起来就像是：

I've got an endpoint looking like that :

public class LoginEndpoint {
    @GET
    @Path(LOGIN)
    @Produces(MediaType.APPLICATION_JSON)
    public Customer login(@QueryParam("email") String email, @QueryParam("password") String password) {
        return null;
    }
}

比标准路由做的工作。

Than a standard route is doing the job.

如何知道骆驼（或JAX-RS，或者CXFRS组成部分，我不知道...），以允许跨域请求？

How can I tell Camel (or JAX-RS, or the CXFRS component, I don't know...) to allow Cross Domain Requests ?

推荐答案

您需要在您的端点添加注释

You need to add an annotation on your endpoint

@CrossOriginResourceSharing(allowAllOrigins = true, allowAnyHeaders = true)
public class LoginEndpoint {
    @GET
    @Path(LOGIN)
    @Produces(MediaType.APPLICATION_JSON)
    public Customer login(@QueryParam("email") String email, @QueryParam("password") String password) {
        return null;
    }
}

我不认为你需要一个新的依赖，作为注释是骆驼CXF。但是，你需要告诉骆驼寻找这个注释，用供应商的标签。

I don't think you need a new dependency, as the annotation is in camel-cxf. But you need to tell Camel to look for this annotation, using the providers tag.

<cxf:rsServer id="login" address="your adress"
        serviceClass="LoginEndpoint">
    <cxf:providers>
        <bean class="org.apache.cxf.jaxrs.cors.CrossOriginResourceSharingFilter" />
    </cxf:providers>
</cxf:rsServer>

那么你应该罚款（但请记住，这只是本地测试）。

Then you should be fine (but remember that is just for local testing).
