spring security很奇怪的问题? 在配置类红使用access表达式一?400报错

.antMatchers("/ll").access("@myServiceImpl.hasPermission(request,authentication)")
    //正常

@PreAuthorize("@myServiceImpl.hasPermission(request,authentication)")
@RequestMapping("/test1")
public String test1(HttpServletRequest request) {
    return "test1";
}//报错

EL1008E: Property or field 'request' cannot be found on object of type 'org.springframework.security.access.expression.method.MethodSecurityExpressionRoot' - maybe not public or not valid?

这是判断逻辑;

public boolean hasPermission(HttpServletRequest request, Authentication authentication) {

   Object obj = authentication.getPrincipal();

   if (obj instanceof UserDetails) {
      UserDetails user = (UserDetails) obj;
      Collection<? extends GrantedAuthority> authorities = user.getAuthorities();
      return authorities.contains(new SimpleGrantedAuthority(request.getRequestURI()));
   }
   return false;
}
