java - Jersey Client API - 使用 jersey rest api 的身份验证错误

Question

我在调用 rest API 之前创建了一个授权过滤器，但我收到 404 错误消息。下面是我创建的类。

--RestAuthenticationFilter

package com.sms.Security;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class RestAuthenticationFilter implements javax.servlet.Filter {
    public static final String AUTHENTICATION_HEADER = "Authorization";

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain filter) throws IOException, ServletException {
        if (request instanceof HttpServletRequest) {
            HttpServletRequest httpServletRequest = (HttpServletRequest) request;
            String authCredentials = httpServletRequest
                    .getHeader(AUTHENTICATION_HEADER);

            // better injected
            AuthenticationService authenticationService = new AuthenticationService();

            boolean authenticationStatus = authenticationService
                    .authenticate(authCredentials);

            if (authenticationStatus) {
                filter.doFilter(request, response);
            } else {
                if (response instanceof HttpServletResponse) {
                    HttpServletResponse httpServletResponse = (HttpServletResponse) response;
                    httpServletResponse
                            .setStatus(HttpServletResponse.SC_UNAUTHORIZED);
                }
            }
        }
    }

    @Override
    public void destroy() {
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {
    }
}

--认证服务

package com.sms.Security;

import java.io.IOException;
import java.util.Base64;
import java.util.StringTokenizer;

public class AuthenticationService {


    public boolean authenticate(String authCredentials) {

        if (null == authCredentials)
            return false;
        // header value format will be "Basic encodedstring" for Basic
        // authentication. Example "Basic YWRtaW46YWRtaW4="
        final String encodedUserPassword = authCredentials.replaceFirst("Basic"
                + " ", "");
        String usernameAndPassword = null;
        try {
            byte[] decodedBytes = Base64.getDecoder().decode(
                    encodedUserPassword);
            usernameAndPassword = new String(decodedBytes, "UTF-8");
        } catch (IOException e) {
            e.printStackTrace();
        }
        final StringTokenizer tokenizer = new StringTokenizer(
                usernameAndPassword, ":");
        final String username = tokenizer.nextToken();
        final String password = tokenizer.nextToken();

        // we have fixed the userid and password as admin
        // call some UserService/LDAP here
        boolean authenticationStatus = "admin".equals(username)
                && "admin".equals(password);
        return authenticationStatus;
    }
}

Answer 1

看起来 RestAuthenticationFilter 在类路径中不可用，因此出现 ClassNotFoundException。请仔细检查您是否正在编译它并将其放入类路径中。
