Class SeContainerInitializer

java.lang.Object
jakarta.enterprise.inject.se.SeContainerInitializer
public abstract class SeContainerInitializer extends Object
A CDI container initializer for Java SE. An instance may be obtained by calling newInstance() static method.

Typical usage looks like this: 

 SeContainer container = SeContainerInitializer.newInstance().initialize();
 container.select(Foo.class).get();
 container.close();

Since SeContainer interface implements AutoCloseable: 

 try (SeContainer container = SeContainerInitializer.newInstance().initialize()) {
     container.select(Foo.class).get();
 }

By default, the discovery is enabled so that all beans from all discovered bean archives are considered. However, it's possible to define a "synthetic" bean archive, or the set of bean classes and enablement respectively: 

 SeContainer container = SeContainerInitializer.newInstance().addBeanClasses(Foo.class, Bar.class).selectAlternatives(Bar.class).initialize());

Moreover, it's also possible to disable the discovery completely so that only the "synthetic" bean archive is considered: 

 SeContainer container = SeContainerInitializer.newInstance().disableDiscovery().addBeanClasses(Foo.class, Bar.class).initialize());

In the same manner, it is possible to explicitly declare interceptors, decorators, extensions and implementation specific options using the builder. 

 SeContainerInitializer containerInitializer = SeContainerInitializer.newInstance()
         .disableDiscovery()
         .addPackages(Main.class, Utils.class)
         .enableInterceptors(TransactionalInterceptor.class)
         .addProperty("property", true);
 SeContainer container = container.initialize();

CDI Lite implementations are not required to provide support for CDI in Java SE.

      Packages of the specified classes will be scanned and found classes will be added to the set of bean classes for the synthetic bean archive.*

      Note that the scanning possibilities are limited. Therefore, only directories and jar files from the filesystem are supported.

      Scanning may also have negative impact on SE performance.

      Parameters:
      scanRecursively - should subpackages be scanned or not

      Returns:
      self

    • addPackages

      public abstract SeContainerInitializer addPackages(Package... packages)

    • addPackages

      public abstract SeContainerInitializer addPackages(boolean scanRecursively, Package... packages)
      All classes from the specified packages will be added to the set of bean classes for the synthetic bean archive.

      Note that the scanning possibilities are limited. Therefore, only directories and jar files from the filesystem are supported.

      Scanning may also have negative impact on SE performance.
