login intercepter do not work in spring - spring

Question

all. i was using spring4 in my project. and add and interceptor extends HandlerInterceptorAdapter, then overwrite prehandle method. but i found it does not work when i was doing spring mock test.
i have configure it in springmvc-servlet.xml , like this:
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.suerpay.common.interceptor.LoginInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>
and here is code of LoginInteceptor:
public class LoginInterceptor extends HandlerInterceptorAdapter {
#Autowired
LoginServiceRedis loginServiceRedis;
#Autowired
UserServiceDB userServiceDB;
Logger logger = LoggerFactory.getLogger(getClass());
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
logger.info("start login interceptor");
if (isLoginRequired(handler)) {
String ticket = request.getHeader(GlobalConstants.TICKET_HEADER);
if (StringUtils.isEmpty(ticket)) {
throw new UnAuthorizedException(ResultCodeConstants.USER_NOT_LOGIN);
}
String userName = loginServiceRedis.getUserNameByTicket(ticket);
Long userId = userServiceDB.getUserIdByName(userName);
if (null == userId) {
throw new UnAuthorizedException(ResultCodeConstants.USER_NOT_LOGIN);
}
ThreadContextHolder.setCurrentUserId(userId);
}
logger.info("finish login interceptor");
return true;
}
private boolean isLoginRequired(Object handler) {
HandlerMethod handlerMethod = (HandlerMethod) handler;
Method method = handlerMethod.getMethod();
LoginRequired loginRequired = method.getAnnotation(LoginRequired.class);
if (null != loginRequired) {
return true;
}
return false;
}
}
i think i have do everything , but just can not get into breakpoint.
who can tell me why?:(
