SpringBoot+Redis防止接口重复提交问题

@Component
public class RepeatSubmitInterceptor extends HandlerInterceptorAdapter {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    //防重时间间隔（秒）
    private final int duration = 1;

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        if (request.getDispatcherType() == DispatcherType.ERROR){
            return true;
        }
        String token = request.getHeader("token");
        String lockKey = "RepeatSubmit:" + token + ":" + request.getServletPath();
        Boolean result = stringRedisTemplate.opsForValue().setIfAbsent(lockKey, "", duration, TimeUnit.SECONDS);
        if (!result){
            throw new Exception("请勿重复提交");
        }

        return true;
    }
}

@Configuration
public class MvcConfig implements WebMvcConfigurer {

    @Autowired
    private RepeatSubmitInterceptor repeatSubmitInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(repeatSubmitInterceptor);
    }
}
