@Documented
@Target(value=PACKAGE)
public @interface Configuration
A configuration is a grouping of bean definitions under a package. A configuration can have requirements applied
to it with Requires
such that the entire configuration only loads of the requirements are met. For example consider the following package-info.java
file:
@Configuration @Requires(classes = Cluster.class) package io.micronaut.configuration.cassandra; import com.datastax.driver.core.Cluster; import io.micronaut.context.annotation.Configuration; import io.micronaut.context.annotation.Requires;
In the example above the Requires
annotation ensures all beans contained within the package are loaded only if the Cluster
class is present on the classpath.
The ApplicationContextBuilder.include(String...)
and ApplicationContextBuilder.exclude(String...)
methods can also be used to control which configurations are
loaded when building the ApplicationContext
Requires

ApplicationContextBuilder.exclude(String...)
