HandlerInterceptorAdapter和Zuul Filter

Question

有可能增加一个HandlerInterceptorAdapter与Zuul配置.我需要拦截对特定资源的请求,但我想因为我有Zuul过滤器配置,所以从不调用拦截器.

有可能吗？

Answer 1

我试图实现同样的目标.我们有一些Spring MVC控制器和Zuul代理.但我仍然希望使用相同的拦截器.

这里的问题是zuul在自己的ZuulServlet中运行,并且不会从你的MVC servlet中获取拦截器.Spring Cloud:ZuulConfiguration.java配置ZuulHandlerMapping,这是唯一可以设置拦截器的地方,但它不可配置.因此,您需要InstantiationAwareBeanPostProcessorAdapter干扰bean的创建,在实例化之后但在初始化之前(在初始化拦截器之前)设置拦截器.

这对我有用:

@Configuration
@RequiredArgsConstructor
public class ZuulHandlerBeanPostProcessor extends InstantiationAwareBeanPostProcessorAdapter {

    @NonNull
    private final MyInterceptor myInterceptor;

    @Override
    public boolean postProcessAfterInstantiation(final Object bean, final String beanName) throws BeansException {

        if (bean instanceof ZuulHandlerMapping) {

            val zuulHandlerMapping = (ZuulHandlerMapping) bean;
            zuulHandlerMapping.setInterceptors(myInterceptor);
        }

        return super.postProcessAfterInstantiation(bean, beanName);
    }

}
