public @interface SpringBootApplication

Indicates a configuration class that declares one or more @Bean methods and also triggers auto-configuration, component scanning, and configuration properties scanning. This is a convenience annotation that is equivalent to declaring @Configuration, @EnableAutoConfiguration, @ComponentScan, and @ConfigurationPropertiesScan.

Element Detail

exclude

@AliasFor(annotation=EnableAutoConfiguration.class)
public abstract 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)
public abstract 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")
public abstract String[] scanBasePackages

Base packages to scan for annotated components. Use scanBasePackageClasses() for a type-safe alternative to String-based package names.

Returns:

base packages to scan

Since:

1.3.0

Default:

{}

scanBasePackageClasses

@AliasFor(annotation=org.springframework.context.annotation.ComponentScan.class,
          attribute="basePackageClasses")
public abstract 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.

Returns:

base packages to scan

Since:

1.3.0

Default:

{}

proxyBeanMethods

@AliasFor(annotation=org.springframework.context.annotation.Configuration.class)
public abstract 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
