java - Dropwizard + Raml -> 空资源

Question

当我启动服务器时，出现一条警告，提示我的资源为空(结果为 404):

WARN  org.glassfish.jersey.internal.Errors - The following warnings have been detected: WARNING: A resource, Resource{"helloz", 0 child resources, 0 resource methods, 0 sub-resource locator, 0 method handler classes, 0 method handler instances}, with path "helloz" is empty. It has no resource (or sub resource) methods neither sub resource locators defined.

实现:

public class SayHello implements Helloz {

    @Override
    public PostHellozResponse postHelloz(@QueryParam("access_token") String accessToken, HelloSchema entity) throws Exception {
        System.out.println("Hello World!");
        return PostHellozResponse.withJsonOK(null);
    }
}

在 Application#run 中，我只执行以下操作:environment.jersey().register(SayHello.class);

好的，这并不明显——您需要删除实现类中的注释:

错误

public class SayHello implements Helloz {

    @Override
    public PostHellozResponse postHelloz(@QueryParam("access_token") String accessToken, HelloSchema entity) throws Exception {
        System.out.println("Hello World!");
        return PostHellozResponse.withJsonOK(null);
    }
}

正确:

public class SayHello implements Helloz {

    @Override
    public PostHellozResponse postHelloz(String accessToken, HelloSchema entity) throws Exception {
        System.out.println("Hello World!");
        return PostHellozResponse.withJsonOK(null);
    }
}
