Element Detail

value

@AliasFor(value="basePackages")
public abstract String[] value

Alias for the basePackages() attribute. Allows for more concise annotation declarations e.g.: @ConfigurationPropertiesScan("org.my.pkg") instead of @ConfigurationPropertiesScan(basePackages="org.my.pkg").

Returns:

the base packages to scan

Default:

{}

basePackages

@AliasFor(value="value")
public abstract String[] basePackages

Base packages to scan for configuration properties. value() is an alias for (and mutually exclusive with) this attribute.

Use basePackageClasses() for a type-safe alternative to String-based package names.

Returns:

the base packages to scan

Default:

{}

basePackageClasses

public abstract Class<?>[] basePackageClasses

Type-safe alternative to basePackages() for specifying the packages to scan for configuration properties. 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:

classes from the base packages to scan

Default:

{}
