Package org.springframework.boot.autoconfigure

Annotation Interface SpringBootApplication

@Target(TYPE) @Retention(RUNTIME) @Documented @Inherited @SpringBootConfiguration @EnableAutoConfiguration @ComponentScan(excludeFilters={@Filter(type=CUSTOM,classes=TypeExcludeFilter.class),}) public @interface SpringBootApplication
Indicates a configuration class that declares one or more @Bean methods and also triggers auto-configuration and component scanning. This is a convenience annotation that is equivalent to declaring @SpringBootConfiguration, @EnableAutoConfiguration and @ComponentScan.

  • Element Details

    • exclude

      @AliasFor(annotation=EnableAutoConfiguration.class) Class<?>[] exclude
      Exclude specific auto-configuration classes such that they will never be applied.
      Returns:
      the classes to exclude
      Default:
      {}

    • excludeName

      @AliasFor(annotation=EnableAutoConfiguration.class) String[] excludeName
      Exclude specific auto-configuration class names such that they will never be applied.
      Returns:
      the class names to exclude
      Since:
      1.3.0
      Default:
      {}

    • scanBasePackages

      @AliasFor(annotation=org.springframework.context.annotation.ComponentScan.class, attribute="basePackages") String[] scanBasePackages
      Base packages to scan for annotated components. Use scanBasePackageClasses() for a type-safe alternative to String-based package names.

      Note: this setting is an alias for @ComponentScan only. It has no effect on @Entity scanning or Spring Data Repository scanning. For those you should add @EntityScan and @Enable...Repositories annotations.

      Returns:
      base packages to scan
      Since:
      1.3.0
      Default:
      {}

    • scanBasePackageClasses

      @AliasFor(annotation=org.springframework.context.annotation.ComponentScan.class, attribute="basePackageClasses") Class<?>[] scanBasePackageClasses
      Type-safe alternative to scanBasePackages() for specifying the packages to scan for annotated components. The package of each class specified will be scanned.

      Consider creating a special no-op marker class or interface in each package that serves no purpose other than being referenced by this attribute.

      Note: this setting is an alias for @ComponentScan only. It has no effect on @Entity scanning or Spring Data Repository scanning. For those you should add @EntityScan and @Enable...Repositories annotations.

      Returns:
      base packages to scan
      Since:
      1.3.0
      Default:
      {}

    • nameGenerator

      @AliasFor(annotation=org.springframework.context.annotation.ComponentScan.class, attribute="nameGenerator") Class<? extends BeanNameGenerator> nameGenerator
      The BeanNameGenerator class to be used for naming detected components within the Spring container.

      The default value of the BeanNameGenerator interface itself indicates that the scanner used to process this @SpringBootApplication annotation should use its inherited bean name generator, e.g. the default AnnotationBeanNameGenerator or any custom instance supplied to the application context at bootstrap time.

      Returns:
      BeanNameGenerator to use
      Since:
      2.3.0

      Default:
      org.springframework.beans.factory.support.BeanNameGenerator.class

    • proxyBeanMethods

      @AliasFor(annotation=org.springframework.context.annotation.Configuration.class) boolean proxyBeanMethods
      Specify whether @Bean methods should get proxied in order to enforce bean lifecycle behavior, e.g. to return shared singleton bean instances even in case of direct @Bean method calls in user code. This feature requires method interception, implemented through a runtime-generated CGLIB subclass which comes with limitations such as the configuration class and its methods not being allowed to declare final.

      The default is true, allowing for 'inter-bean references' within the configuration class as well as for external calls to this configuration's @Bean methods, e.g. from another configuration class. If this is not needed since each of this particular configuration's @Bean methods is self-contained and designed as a plain factory method for container use, switch this flag to false in order to avoid CGLIB subclass processing.

      Turning off bean method interception effectively processes @Bean methods individually like when declared on non-@Configuration classes, a.k.a. "@Bean Lite Mode" (see @Bean's javadoc). It is therefore behaviorally equivalent to removing the @Configuration stereotype.

      Returns:
      whether to proxy @Bean methods
      Since:
      2.2
      Default:
      true
