如何允许 CDI 将资源注入 RESTful Web 服务资源?我使用weld 2 (cdi)、jersey (jaxrs) 和grizzly (web server) 在标准java 上运行。这是我的简单网络资源:
import training.student.StudentRepository;
import javax.inject.Inject;
import javax.ws.rs.*;
@Path("student")
public class StudentWebResource {
@Inject
private StudentRepository studentRepository;
@GET
@Path("count")
@Produces(MediaType.TEXT_PLAIN)
public Integer getCount() {
return studentRepository.studentCount();
}
}
下面是我如何焊接启动我的简单 Web 服务器:
public class Main {
public static void main(String[] args) throws Exception {
startCdiApplication();
}
public static void startCdiApplication() throws Exception {
Weld weld = new Weld();
try {
WeldContainer container = weld.initialize();
Application application = container.instance().select(WebServer.class).get();
application.run();
}
finally {
weld.shutdown();
}
}
}
我怀疑需要修改代码以通知球衣使用焊接进行 CDI 注入分辨率:
...
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;
public class WebServer implements Application {
/*
* startup the grizzly http server to make available the restful web services
*/
private void startWebServer() throws IOException, InterruptedException {
final ResourceConfig resourceConfig = new ResourceConfig().packages("training.webservice").register(new JacksonFeature());
final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(getBaseUri(), resourceConfig);
server.start();
Thread.currentThread().join();
}
...
@Override
public void run() throws IOException, InterruptedException {
startWebServer();
}
}
