@Documented @Inherited @Retention(value=RUNTIME) @Target(value=TYPE) public @interface ContextConfiguration
@ContextConfiguration
defines class-level metadata that is used to determine
how to load and configure an ApplicationContext
for integration tests.
Prior to Spring 3.1, only path-based resource locations (typically XML configuration
files) were supported. As of Spring 3.1, context loaders may
choose to support either path-based or class-based resources. As of
Spring 4.0.4, context loaders may choose to support path-based
and class-based resources simultaneously. Consequently
@ContextConfiguration
can be used to declare either path-based resource
locations (via the locations()
or value()
attribute) or
annotated classes (via the classes()
attribute). Note, however, that most
implementations of SmartContextLoader
only support a single resource type. As
of Spring 4.1, path-based resource locations may be either XML configuration files or
Groovy scripts (if Groovy is on the classpath). Of course, third-party frameworks may
choose to support additional types of path-based resources.
The term annotated class can refer to any of the following.
@Configuration
@Component
,
@Service
,
@Repository
, etc.)javax.inject
annotations@Bean
-methods
Consult the Javadoc for @Configuration
and @Bean
for further
information regarding the configuration and semantics of annotated classes.
As of Spring Framework 4.0, this annotation may be used as a meta-annotation to create custom composed annotations.

Check out the Javadoc for

default locations that are going to be used if none are specified.
Note that the aforementioned default rules only apply for a standard
AbstractContextLoader
subclass such as
GenericXmlContextLoader
or
GenericGroovyXmlContextLoader
which are the effective default implementations used at runtime if
locations
are configured. See the documentation for loader()
for further details regarding default loaders.

The concrete ConfigurableApplicationContext
type supported by each
declared initializer must be compatible with the type of ApplicationContext
created by the SmartContextLoader
in use.
SmartContextLoader
implementations typically detect whether
Spring's Ordered
interface has been
implemented or if the @Order
annotation is present and sort instances accordingly prior to invoking them.

public abstract boolean inheritLocations
resource locations
or annotated
classes from test superclasses should be inherited.
The default value is true
. This means that an annotated
class will inherit the resource locations or annotated classes
defined by test superclasses. Specifically, the resource locations or
annotated classes for a given test class will be appended to the list of
resource locations or annotated classes defined by test superclasses.
Thus, subclasses have the option of extending the list of resource
locations or annotated classes.
If inheritLocations
is set to false
, the
resource locations or annotated classes for the annotated class
will shadow and effectively replace any resource locations
or annotated classes defined by superclasses.
In the following example that uses path-based resource locations, the
ApplicationContext
for ExtendedTest
will be loaded from
"base-context.xml"
and
"extended-context.xml"
, in that order. Beans defined in
"extended-context.xml"
may therefore override those defined
in "base-context.xml"
.
@ContextConfiguration("base-context.xml") public class BaseTest { // ... } @ContextConfiguration("extended-context.xml") public class ExtendedTest extends BaseTest { // ... }
Similarly, in the following example that uses annotated
classes, the
ApplicationContext
for ExtendedTest
will be loaded from the
BaseConfig
and ExtendedConfig
configuration classes, in that order. Beans defined in
ExtendedConfig
may therefore override those defined in
BaseConfig
.
@ContextConfiguration(classes=BaseConfig.class) public class BaseTest { // ... } @ContextConfiguration(classes=ExtendedConfig.class) public class ExtendedTest extends BaseTest { // ... }
public abstract boolean inheritInitializers
The default value is true
. This means that an annotated
class will inherit the application context initializers defined
by test superclasses. Specifically, the initializers for a given test
class will be added to the set of initializers defined by test
superclasses. Thus, subclasses have the option of extending the
set of initializers.
If inheritInitializers
is set to false
, the
initializers for the annotated class will shadow and effectively
replace any initializers defined by superclasses.
In the following example, the
ApplicationContext
for ExtendedTest
will be initialized using
BaseInitializer
and ExtendedInitializer
.
Note, however, that the order in which the initializers are invoked
depends on whether they implement Ordered
or are annotated with @Order
.
@ContextConfiguration(initializers = BaseInitializer.class) public class BaseTest { // ... } @ContextConfiguration(initializers = ExtendedInitializer.class) public class ExtendedTest extends BaseTest { // ... }
public abstract Class<? extends ContextLoader> loader
SmartContextLoader
(or ContextLoader
) to use
for loading an ApplicationContext
.
If not specified, the loader will be inherited from the first superclass
that is annotated with @ContextConfiguration
and specifies an
explicit loader. If no class in the hierarchy specifies an explicit
loader, a default loader will be used instead.
The default concrete implementation chosen at runtime will be either
DelegatingSmartContextLoader
or
WebDelegatingSmartContextLoader
depending on the absence or presence of
@WebAppConfiguration
. For further details on the default behavior
of various concrete SmartContextLoaders
, check out the Javadoc for
AbstractContextLoader
,
GenericXmlContextLoader
,
GenericGroovyXmlContextLoader
,
AnnotationConfigContextLoader
,
GenericXmlWebContextLoader
,
GenericGroovyXmlWebContextLoader
, and
AnnotationConfigWebContextLoader
.
public abstract String name
If not specified the name will be inferred based on the numerical level within all declared contexts within the hierarchy.
This attribute is only applicable when used within a test class hierarchy
that is configured using @ContextHierarchy
, in which case the name
can be used for merging or overriding this configuration
with configuration of the same name in hierarchy levels defined in superclasses.
See the Javadoc for @ContextHierarchy
for details.
