Question

当我尝试访问zuul下游的api时遇到异常。下游服务配置有Spring Security，Spring Session和Hazel Cast

请找到堆栈跟踪：

虚假客户端，以调用下游服务：

@FeignClient（“某些服务名称” +“ / validateToken”）公共接口TokenValidationProxy {

@GetMapping(value = "", headers = "x-auth-token")
public void validateToken(@RequestHeader("x-auth-token") String token);

}

Zuul过滤器，在这里我从zuul调用下游服务以验证令牌：

公共类TokenValidationFilter扩展了ZuulFilter { 私有静态Logger日志= LoggerFactory.getLogger（TokenValidationFilter.class）;

@Autowired
private TokenValidationProxy tokenValidationProxy;

@Override
public String filterType() {
    return "pre";
}

@Override
public int filterOrder() {
    return 1;
}

@Override
public boolean shouldFilter() {
    return true;
}

@Override
public Object run() {
    RequestContext ctx = RequestContext.getCurrentContext();
    HttpServletRequest request = ctx.getRequest();

    log.info(String.format("%s request to %s", request.getMethod(), request.getRequestURL().toString()));
    if(! request.getRequestURL().toString().endsWith("/login")) {
        try {
            System.out.println(request.getHeader("x-auth-token"));
            tokenValidationProxy.validateToken(request.getHeader("x-auth-token"));
            return null;
        } catch(Exception e) {
            e.printStackTrace();
            try {
                ctx.getResponse().sendError(401,"your token is invalid");
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }
    }

java.lang.ClassNotFoundException：org.springframework.session.hazelcast.SessionUpdateEntryProcessor
