Filter is not initialized on startup with Undertow

[ldcsaa]

spring-boot (v1.5.18.RELEASE) can not init filter on startup while use undertow server, even if I set the property "server.undertow.eager-filter-init=true".
But tomcat server can do it correctly.

@ldcsaa Can you please share a complete, minimal project that reproduces the problem? That should be something that we can unzip or a Git repository that we can clone and then run.

This is my demo project with undertwo server. 'MyFilter' would be initialized until send first request to 'http://localhsot:8080'.

server.undertow.eager-filter-init isn't supported in Spring Boot 1.5. The property was introduced in Spring Boot 2.0 to fix issue #9232 which this issue duplicates.

Thanks~
But how to let undertow initializes filters on startup just like tomcat in spring-boot-1.5.x ?

@ldcsaa Please don't make the same comment on multiple issues.
