无法使用弹簧自定义过滤器对用户进行身份验证

【中文标题】无法使用弹簧自定义过滤器对用户进行身份验证【英文标题】：Unable to authentication a user with spring custom filter 【发布时间】：2017-03-31 01:16:06 【问题描述】：我正在尝试通过使用 jpa 从数据库中比较用户名和密码来对登录请求的用户进行身份验证，但有些身份验证失败并返回 401 错误。
请求流程如下：
来自客户端的请求：
login: function(data,success, error)
$http.post('auth', data).success(success).error(error);
application.yml 配置为接受"auth" 的请求
# config context path to "/" by setting an empty string
server:
contextPath:
# JACKSON
spring:
jackson:
serialization:
INDENT_OUTPUT: true
jwt:
header: Authorization
secret: mySecret
expiration: 604800
route:
authentication:
path: auth
refresh: refresh
logging:
level:
org.springframework:
security: DEBUG
网络安全：
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception
httpSecurity
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.authorizeRequests()
.antMatchers(HttpMethod.POST, "/registration").permitAll()
.antMatchers("/auth/**").permitAll()
.anyRequest().authenticated();
// Custom JWT based security filter
httpSecurity
.addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
// disable page caching
httpSecurity.headers().cacheControl();
我不确定流程是如何进行的，但是请求到达下面类中的createAuthenticationToken() 方法并打印此行System.out.println("Authenticate called in createAuthenticationToken");，但没有调用authenticationManager.authenticate()，即使我我能够从JwtAuthenticationRequest authenticationRequest bean 打印凭据。
@RestController
public class AuthenticationRestController
@Value("$jwt.header")
private String tokenHeader;
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private JwtTokenUtil jwtTokenUtil;
@Autowired
private UserDetailsService userDetailsService;
@RequestMapping(value = "$jwt.route.authentication.path", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtAuthenticationRequest authenticationRequest, Device device) throws AuthenticationException
System.out.println("Authenticate called in createAuthenticationToken"); //PRINTS THIS LINE
// THIS IS NOT CALLED
final Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(
authenticationRequest.getUsername(),
authenticationRequest.getPassword()
)
);
System.out.println("authenticationManager.authenticate(JWTAuthRequest) is=" + authentication); //THIS IS NOT PRINTED
SecurityContextHolder.getContext().setAuthentication(authentication);
// Reload password post-security so we can generate token
final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
System.out.println("userDetailsService.loadUserByUsername->userDetails is->" + userDetails);
final String token = jwtTokenUtil.generateToken(userDetails, device);
System.out.println("jwtTokenUtil.generateToken(userDetails, device) is->" + token);
// Return the token
return ResponseEntity.ok(new JwtAuthenticationResponse(token));
从这里开始，它转到自定义入口点并向客户端返回 401 错误。为什么即使存在凭据也不对用户进行身份验证并返回令牌？我做错了什么？
入口点：
@Component
public class JwtAuthenticationEntryPoint implements AuthenticationEntryPoint, Serializable
private static final long serialVersionUID = -8970718410437077606L;
@Override
public void commence(HttpServletRequest request,
HttpServletResponse response,
AuthenticationException authException) throws IOException
System.out.println("ENTRY POINT"); //PRINTS THIS
// This is invoked when user tries to access a secured REST resource without supplying any credentials
// We should just send a 401 Unauthorized response because there is no 'login page' to redirect to
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized");
我从https://github.com/szerhusenBC/jwt-spring-security-demo.git得到了上面的代码概念
更新
在 application.yml 中启用调试日志时出现此错误：

您的代码似乎只是在设置用户名和密码。要进行身份验证，您需要传入 3 个参数 - 用户名、密码和授予权限的集合。如果你有这个，通过它。否则，将 null 作为第三个参数传递。
希望这对你有用。
【讨论】：
但是我在注册时为每个用户分配了角色。登录时，我认为我不必设置角色。我猜它应该从数据库中获取。我启用了调试日志，但出现了一些错误。请检查更新的问题 感谢您的回答，但问题是别的。我修好了它。交易 @Satyadev 你是怎么解决这个问题的？我遇到了类似的情况？？ @YogenRai 我不记得我是怎么做到的。这是我正在为练习而进行的一个示例项目。我会检查我是否还有那个项目。 @Satyadev 非常感谢您的帮助！！ :)以上是关于无法使用弹簧自定义过滤器对用户进行身份验证的主要内容，如果未能解决你的问题，请参考以下文章
