Prior to this change, the Spring MVC auto-configuration would add a new
formatter to convert `java.util.Date` to/from `String` using the
configured configuration property `spring.mvc.date-format`.
This commit adds a new `WebConversionService` class that registers
date formatters with a custom date format, or register the default ones
if no custom configuration is provided.
This avoids duplicating equivalent formatters in the registry.
With this change, date types from `java.util`, `org.joda.time` and
`java.time` are now all supported.
This commit also replicates this feature for WebFlux applications by
adding a new `spring.webflux.date-format` configuration property.
Closes gh-5523

Rather than using two properties to enable or disable reactive and
imperative repositories for a particular store, this commit introduces
a new repository type condition that's backed by a single
spring.data.<store>.repositories.type property. The type can be
auto (automatically enables whatever's available), imperative (enables
imperative repositories), none (enables nothing), or reactive (enables
reactive repositories). The default is auto.
Repositories do not have a reactive option (such as JPA) continue to
have a spring.data.<store>.repositories.enabled property that takes a
boolean value.
Closes gh-11134
If the WebFlux handler commits the response but still sends an error
signal in the reactive pipeline, Spring Boot error handling should not
try to handle that error: once committed, it is impossible to change the
response status or the response headers. Writing to the body might also
lead to invalid responses.
This commit skips error handling if the response is committed and
delegates to Spring Framework's `HttpWebHandlerAdapter` which will log
the error.
Fixes gh-11168
