我有这个服务器初始化类:
package magic.app.main;
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import java.io.IOException;
import java.net.URI;
public class Main {
public static final String BASE_URI = "http://localhost:4747/";
public static void main(String[] args) throws IOException {
/* SOME NON-RELEVANT CODE UP HERE */
final ResourceConfig rc = new ResourceConfig();
rc.packages("magic.app.resource");
rc.register(magic.app.main.CorsSupportFilter.class);
final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI),rc);
/* SOME NON-RELEVANT CODE DOWN HERE */
}
}
我试图在初始化类中注册这个过滤器类:
package magic.app.main;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;
import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;
public class CorsSupportFilter implements ContainerResponseFilter {
@Override
public ContainerResponse filter(ContainerRequest req, ContainerResponse contResp) {
ResponseBuilder resp = Response.fromResponse(contResp.getResponse());
resp.header("Access-Control-Allow-Origin", Configuration.getHttpAllowOrigin())
.header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
String reqHead = req.getHeaderValue("Access-Control-Request-Headers");
if(null != reqHead && !reqHead.equals(null)){
resp.header("Access-Control-Allow-Headers", reqHead);
}
contResp.setResponse(resp.build());
return contResp;
}
}
当我运行该应用程序时,我得到这段日志:
WARNING: A provider magic.app.main.CorsSupportFilter registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. Due to constraint configuration problems the provider magic.app.main.CorsSupportFilter will be ignored.
我正在使用 gradle,这是我的应用程序的 Gradle 构建文件:
