StripPrefixGatewayFilter using wrong parts to rebuild path causes routing 404

chengyouling commented 2 weeks ago

Exception phenomenon: The value is expected to be StripPrefix=2 to rebuild path in the router, however, in some scenarios using StripPrefix=1. This problem occurs occasionally in high-concurrency scenarios, and the target service address is correct by lb.

Gateway version: 2.1.3.RELEASE

Router config：

spring:
  cloud:
    gateway:
      routes:
        - id: consumer
          uri: lb://basic-consumer
          predicates:
            - Path=/api/template/**
          filters:
            - StripPrefix=2

The new path after StripPrefixGatewayFilter logs, the uri address is the basic-consumer service instance exists.

Unfortunately, that version is no longer supported. Can you recreate the issue in the latest version?
