WebMvcMetricsFilter not created after upgrading to Spring Boot 2.7.0 when another user created bean of type FilterRegistrationBean is available

[dariosanna]

After upgrading from Spring Boot 2.6.8 to 2.7.0 WebMvcMetricsAutoConfiguration does not create a WebMvcMetricsFilter bean when a user created FilterRegistrationBean is available, regardless of what type of the filter bean.

In Spring Boot 2.7.0 the FilterRegistrationBean has ConditionalOnMissingBean , whereas Spring Boot 2.6.8 allways creates the bean:

Spring Boot 2.7.0 WebMvcMetricsAutoConfiguration:

@ConditionalOnMissingBean
public FilterRegistrationBean<WebMvcMetricsFilter>

It seems that ConditionalOnMisstingBean ignores the type parameter T when evaluating the condition.

Is that a bug or how to make @ConditionalOnMissingBean respects the type parameter T ?

Best regards.

This seems to be a duplicate of #31150.

Indeed it is, @izeye. Thanks.
