1 自定义过滤器

public class MyFilter extends ZuulFilter {

    public boolean shouldFilter() {
        return true;
    }

    public Object run() {
        System.out.println("执行 MyFilter 过滤器");
        return null;
    }

    @Override
    public String filterType() {
        return FilterConstants.ROUTE_TYPE;
    }

    @Override
    public int filterOrder() {
