Java jersey 导入包

Question

我正在尝试重新制作此处找到的解决方案 Basic HTTP authentication with Jersey / Grizzly

到目前为止，我已经包含了这些导入

import javax.ws.rs.WebApplicationException;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.HttpHeaders;
import javax.ws.rs.core.Response.Status;

经过一番搜索，我把这个加入了

import org.glassfish.jersey.server.ContainerRequest;

我的问题是我得到了这些错误

... AuthFilter is not abstract and does not override abstract method filter(ContainerRequestContext) in ContainerRequestFilter

... method does not override or implement a method from a supertype

... cannot find symbol
[ERROR] symbol:   method getHeaderValue(String)
[ERROR] location: variable containerRequest of type ContainerRequest

如果你不想切换标签，代码在这里

    @Override
    public ContainerRequest filter(ContainerRequest containerRequest) 
            throws WebApplicationException {

        // Automatically allow certain requests.
        String method = containerRequest.getMethod();
        String path = containerRequest.getPath(true);
        if (method.equals("GET") && path.equals("application.wadl"))
            return containerRequest;

        // Get the authentication passed in HTTP headers parameters
        String auth = containerRequest.getHeaderValue("authorization");
        if (auth == null)
            throw unauthorized;

不幸的是，我没有必要的声誉来询问 OP，因此我们不胜感激。

编辑：显然是 com.sun.jersey.spi.container.ContainerRequest 不包括 getHeadervalue 和 jersey 2.0 找不到的那个有什么办法吗？

import javax.ws.rs.WebApplicationException;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.container.ContainerRequestContext;

import org.glassfish.jersey.internal.util.Base64;
import java.io.IOException;

public class AuthFilter implements ContainerRequestFilter {

    @Override
    public void filter(ContainerRequestContext requestContext) 
            throws IOException {

        String method = requestContext.getMethod();
        String path = requestContext.getUriInfo().getPath();


        String auth = requestContext.getHeaderString("authorization");
        if (auth == null)
            throw new AuthenticationException("Too bad");
        //how to import that ^

        auth = auth.replaceFirst("[Bb]asic ", "");

        String entry = new String(Base64.decode(auth));


        if (!entry.equals("admin:password"))
            throw new AuthenticationException("Too bad");
    }
 }

链接中的该类正在实现特定于 Jersey 1，ContainerRequestFilter。该类名从 JAX-RS 2 (Jersey 2.x) 开始成为标准类（只是名称）。该方法的新签名是

import java.io.IOException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;

public class Hello implements ContainerRequestFilter {

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
        requestContext.getMethod();
        requestContext.getUriInfo().getPath();
        requestContext.getHeaderString("authorization");
    } 
}

我将更改后的调用添加到该类中使用的一些类似方法
