泽西岛：无法注入HttpServletRequest，导致hk2错误

Question

我试图将HttpServletRequest注入我的Jersey资源类。我收到了错误＆＃34; java.lang.NoSuchMethodException: The class HttpServletRequest has no constructor marked @Inject and no zero argument constructor＆＃34;。我使用的是Java 8。

据我所知，我正在做一个完全普通的泽西岛应用程序。这是代码，所有这些：

import java.net.URI;

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;

import org.glassfish.jersey.jetty.JettyHttpContainerFactory;
import org.glassfish.jersey.server.ResourceConfig;

public class TestInjection {

    public static void main(String[] args) throws Exception {
        ResourceConfig app = new ResourceConfig();
        app.register(Foo.class);
        URI uri = URI.create("http://localhost:8088/");
        org.eclipse.jetty.server.Server jettyServer = JettyHttpContainerFactory.createServer(uri, app, false);
        jettyServer.start();
    }

    @Path("/hello")
    public static class Foo {

        @GET
        public String go(@Context HttpServletRequest req) {
            return "hello";
        }
    }

}

它在@Context HttpServletRequest部分窒息。如果我将HttpServletRequest设为一个字段，它就会无声地失败并且请求为空。

以下是依赖项。 jersey.version是2.27：

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-server</artifactId>
    <version>${jersey.version}</version>
</dependency>

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-jetty-http</artifactId>
    <version>${jersey.version}</version>
</dependency>

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>${jersey.version}</version>
</dependency>

这是完整的堆栈跟踪。 （我上面报告的错误是通过单步执行代码找到的，所以它有点不同。）

Answer 1

jersey-container-jetty-http仅运行标准HTTP服务器。如果要使用HttpServletRequest，则需要Servlet容器。为此，您需要使用jersey-container-jetty-servlet，而不是使用JettyHttpContainerFactory来创建服务器，您需要使用JettyWebContainerFactory。
