filterOrder
类似spring-core-4.3.4.RELEASE-sources.jar!/org/springframework/core/Ordered.java
/**
* Useful constant for the highest precedence value.
* @see java.lang.Integer#MIN_VALUE
*/
int HIGHEST_PRECEDENCE = Integer.MIN_VALUE;
/**
* Useful constant for the lowest precedence value.
* @see java.lang.Integer#MAX_VALUE
*/
int LOWEST_PRECEDENCE = Integer.MAX_VALUE;
默认越小优先级越高,排查负数的情况下,0优先级最高
RateLimitFilter
com/marcosbarbero/zuul/filters/pre/ratelimit/RateLimitFilter.java
它的order为-1,表示更先执行
