on your classpath you are likely to want a
TomcatServletWebServerFactory
(unless you have defined your own
ServletWebServerFactory
bean).
When using SpringBootApplication
, the auto-configuration of the context is
automatically enabled and adding this annotation has therefore no additional effect.
Auto-configuration tries to be as intelligent as possible and will back-away as you
define more of your own configuration. You can always manually exclude()
any
configuration that you never want to apply (use excludeName()
if you don't
have access to them). You can also exclude them via the
spring.autoconfigure.exclude
property. Auto-configuration is always applied
after user-defined beans have been registered.
The package of the class that is annotated with @EnableAutoConfiguration
,
usually via @SpringBootApplication
, has specific significance and is often used
as a 'default'. For example, it will be used when scanning for @Entity
classes.
It is generally recommended that you place @EnableAutoConfiguration
(if you're
not using @SpringBootApplication
) in a root package so that all sub-packages
and classes can be searched.
Auto-configuration classes are regular Spring Configuration
beans. They are
located using the SpringFactoriesLoader
mechanism (keyed against this class).
Generally auto-configuration beans are @Conditional
beans (most
often using @ConditionalOnClass
and
@ConditionalOnMissingBean
annotations).
