将使用java和SpringBoot框架创建的微服务中的一组ipAdresses列入黑名单

Question

我有一个微型服务，用来询问不同类型和操作系统的设备，但出于一系列原因，我想把几个IP列入黑名单。我有办法做到这一点吗？

您试过使用HandlerInterceptor接口吗？

与WebMvcConfigurerAdapter相结合。这应该能胜任这份工作。

就像这样，这里没有精确的工作代码

//Call after request processing, but before the view is rendered (after controller method call)
@Override
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
    String ip = IPAddressUtil.getClientIpAddress(httpServletRequest);
    List<BlackList> blackLists = blackListDao.findByIp(ip);
    if (blackLists == null || blackLists.size() == 0){
        urlHandle(httpServletRequest, 5000, 10);
    } else {
         //Forced control jump
         modelAndView.setViewName("/errorpage/error.html");
    }
}

BlackListDao类可以是这样的

@Mapper
public interface BlackListDao {
    //Find records by IP
    List<BlackList> findByIp(String IP);
    //Add record
    int addBlackList(@Param("blackList") BlackList blackList);
}

为spring配置Interceptor Webmvcconfigureradapter。

@Configuration
public class MyWebAppConfigurer extends WebMvcConfigurerAdapter {
    @Bean // inject our interceptor as bean
    public HandlerInterceptor getMyInterceptor(){
    return new URLInterceptor();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
    //Multiple interceptors form an interceptor chain
    //Addpathpatterns is used to add interception rules. Here we assume that all links after interception / URL
    //Excludepathpatterns user exclusion
registry.addInterceptor(getMyInterceptor()).addPathPatterns("/url/**");
            super.addInterceptors(registry);
}
