如何在Zuul中捕获HystrixTimeout异常

import com.netflix.zuul.ZuulFilter;
import com.netflix.zuul.context.RequestContext;

public class HystrixTimeoutFilter extends ZuulFilter {

    @Override
    public String filterType() {
        return "error";
    }

    @Override
    public int filterOrder() {
        return 1;
    }

    @Override
    public boolean shouldFilter() {
        return true;
    }

    @Override
    public Object run() {
        RequestContext ctx = RequestContext.getCurrentContext();
        Throwable throwable = ctx.getThrowable();
        if (throwable.getCause() instanceof HystrixTimeoutException) {
            // 在这里处理HystrixTimeout异常
            // 可以记录日志、返回自定义错误信息等
        }
        return null;
    }
}

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Bean;

@EnableZuulProxy
@SpringBootApplication
public class YourApplication {

    public static void main(String[] args) {
        SpringApplication.run(YourApplication.class, args);
    }

    @Bean
    public HystrixTimeoutFilter hystrixTimeoutFilter() {
        return new HystrixTimeoutFilter();
    }
}
