我想通过spring安全性和Json Web Token（JWT）保护我的服务，并通过Spring
session将登录的用户存储在redis中。因此，当用户发送登录请求时，我对用户进行身份验证并将生成的令牌发送回如下所示：

public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtAuthenticationRequest authenticationRequest, Device device) throws AuthenticationException {

    // Perform the security
    final Authentication authentication = authenticationManager.authenticate(
            new UsernamePasswordAuthenticationToken(
                    authenticationRequest.getUsername(),
                    authenticationRequest.getPassword()
            )
    );
    SecurityContextHolder.getContext().setAuthentication(authentication);


    final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
    final String token = jwtTokenUtil.generateToken(userDetails, device);

    // Return the token
    return ResponseEntity.ok(new JwtAuthenticationResponse(token));
}

我也将该用户添加到会话（支持Redis会话）中：

HttpSession session = request.getSession(false);
    if (session != null) {
        session.setMaxInactiveInterval(30 * 600);
        JwtUser user = (JwtUser) authentication.getPrincipal();
        session.setAttribute("user", user);

    }

之后我检查Redis的，我看已经被设置为redis.But当我收到来自用户下一次尝试的用户会话成为 anonymousUser
，理想情况shouldn’t.Reason这个问题的背后，是进入JSESSIONID无效莫名其妙。

        Authentication auth = SecurityContextHolder.getContext().getAuthentication();

我看到调试屏幕主体返回anonymousUser。

我也尝试如下：

@RequestMapping(value = "/username", method = RequestMethod.GET)
@ResponseBody
public String currentUserNameSimple(HttpServletRequest request) {
    Principal principal = request.getUserPrincipal();
    return principal.getName();
}

但是principal为空。

我的redis配置：

@Configuration
@EnableRedisHttpSession 
public class RedisConfig implements BeanClassLoaderAware {

private ClassLoader loader;


@Bean(name = { "defaultRedisSerializer", "springSessionDefaultRedisSerializer" })
public RedisSerializer<Object> springSessionDefaultRedisSerializer() {
    return new GenericJackson2JsonRedisSerializer(objectMapper());

}

@Bean
public HttpSessionStrategy httpSessionStrategy() {
        return new HeaderHttpSessionStrategy(); 
}

@Bean
JedisConnectionFactory jedisConnectionFactory() {
    JedisConnectionFactory jedisConFactory = new JedisConnectionFactory();
    jedisConFactory.setHostName("localhost");
    jedisConFactory.setPort(6379);
    return jedisConFactory;
}

ObjectMapper objectMapper() {
    ObjectMapper mapper = new ObjectMapper();
    mapper.registerModules(SecurityJackson2Modules.getModules(this.loader));
    return mapper;
}

public void setBeanClassLoader(ClassLoader classLoader) {
    this.loader = classLoader;
}

}

没有Redis，一切都会很好，但是有了Redis，我将无法获得当前经过身份验证的用户的主体
