GenericApplicationContext
, suitable for web environments.
Implements ConfigurableWebApplicationContext
, but is not intended for
declarative setup in web.xml
. Instead, it is designed for programmatic setup,
for example for building nested contexts or for use within
WebApplicationInitializers
.
Interprets resource paths as servlet context resources, i.e. as paths beneath
the web application root. Absolute paths — for example, for files outside
the web app root — can be accessed via file:
URLs, as implemented
by AbstractApplicationContext
.
In addition to the special beans detected by
AbstractApplicationContext
,
this class detects a ThemeSource
bean in the context, with the name "themeSource".
Theme support is deprecated as of 6.0
If you wish to register annotated component classes with a
GenericWebApplicationContext
, you can use an
AnnotatedBeanDefinitionReader
, as demonstrated in the following example.
Component classes include in particular
@Configuration
classes but also plain @Component
classes as well as JSR-330 compliant classes using jakarta.inject
annotations.
GenericWebApplicationContext context = new GenericWebApplicationContext(); AnnotatedBeanDefinitionReader reader = new AnnotatedBeanDefinitionReader(context); reader.register(AppConfig.class, UserController.class, UserRepository.class);
If you intend to implement a WebApplicationContext
that reads bean definitions
from configuration files, consider deriving from AbstractRefreshableWebApplicationContext
,
reading the bean definitions in an implementation of the loadBeanDefinitions
method.
