Class AnnotationConfigWebContextLoader

java.lang.Object

org.springframework.test.context.support.AbstractContextLoader

org.springframework.test.context.web.AbstractGenericWebContextLoader

org.springframework.test.context.web.AnnotationConfigWebContextLoader

All Implemented Interfaces:

AotContextLoader, ContextLoader, SmartContextLoader

public class AnnotationConfigWebContextLoader
extends AbstractGenericWebContextLoader

Concrete implementation of AbstractGenericWebContextLoader that loads bean definitions from annotated classes.

See the Javadoc for @ContextConfiguration for a definition of annotated class.

Note: AnnotationConfigWebContextLoader supports annotated classes rather than the String-based resource locations defined by the legacy ContextLoader API. Thus, although AnnotationConfigWebContextLoader extends AbstractGenericWebContextLoader, AnnotationConfigWebContextLoader does not support any String-based methods defined by AbstractContextLoader or AbstractGenericWebContextLoader. Consequently, AnnotationConfigWebContextLoader should chiefly be considered a SmartContextLoader rather than a ContextLoader.

Method Details

processContextConfiguration

public void processContextConfiguration(ContextConfigurationAttributes configAttributes)

Process annotated classes in the supplied ContextConfigurationAttributes.

If the annotated classes are null or empty and AbstractContextLoader.isGenerateDefaultLocations() returns true, this SmartContextLoader will attempt to detect default configuration classes. If defaults are detected they will be set in the supplied configuration attributes. Otherwise, properties in the supplied configuration attributes will not be modified.

Specified by:

processContextConfiguration in interface SmartContextLoader

Overrides:

processContextConfiguration in class AbstractContextLoader

Parameters:

configAttributes - the context configuration attributes to process

See Also:

• SmartContextLoader.processContextConfiguration(ContextConfigurationAttributes)
• AbstractContextLoader.isGenerateDefaultLocations()
• detectDefaultConfigurationClasses(Class)

detectDefaultConfigurationClasses

protected Class<?>[] detectDefaultConfigurationClasses(Class<?> declaringClass)

Detect the default configuration classes for the supplied test class.

The default implementation simply delegates to AnnotationConfigContextLoaderUtils.detectDefaultConfigurationClasses(Class).

Parameters:

declaringClass - the test class that declared @ContextConfiguration

Returns:

an array of default configuration classes, potentially empty but never null

See Also:

• AnnotationConfigContextLoaderUtils

modifyLocations

protected String[] modifyLocations(Class<?> clazz,
 String... locations)

AnnotationConfigWebContextLoader should be used as a SmartContextLoader, not as a legacy ContextLoader. Consequently, this method is not supported.

Overrides:

modifyLocations in class AbstractContextLoader

Parameters:

clazz - the class with which the locations are associated

locations - the resource locations to be modified

Returns:

an array of modified application context resource locations

Throws:

UnsupportedOperationException - in this implementation

See Also:

• AbstractContextLoader.modifyLocations(Class, String...)

generateDefaultLocations

protected String[] generateDefaultLocations(Class<?> clazz)

AnnotationConfigWebContextLoader should be used as a SmartContextLoader, not as a legacy ContextLoader. Consequently, this method is not supported.

Overrides:

generateDefaultLocations in class AbstractContextLoader

Parameters:

clazz - the class for which the default locations are to be generated

Returns:

an array of default application context resource locations

Throws:

UnsupportedOperationException - in this implementation

See Also:

• AbstractContextLoader.generateDefaultLocations(Class)

getResourceSuffix

protected String getResourceSuffix()

AnnotationConfigWebContextLoader should be used as a SmartContextLoader, not as a legacy ContextLoader. Consequently, this method is not supported.

Specified by:

getResourceSuffix in class AbstractContextLoader

Returns:

the resource suffix; never null or empty

Throws:

UnsupportedOperationException - in this implementation

See Also:

• AbstractContextLoader.getResourceSuffix()

loadBeanDefinitions

protected void loadBeanDefinitions(GenericWebApplicationContext context,
 WebMergedContextConfiguration webMergedConfig)

Register classes in the supplied context from the classes in the supplied WebMergedContextConfiguration.

Each class must represent an annotated class. An AnnotatedBeanDefinitionReader is used to register the appropriate bean definitions.

Specified by:

loadBeanDefinitions in class AbstractGenericWebContextLoader

Parameters:

context - the context in which the annotated classes should be registered

webMergedConfig - the merged configuration from which the classes should be retrieved

See Also:

• AbstractGenericWebContextLoader.loadBeanDefinitions(GenericWebApplicationContext, WebMergedContextConfiguration)

validateMergedContextConfiguration

protected void validateMergedContextConfiguration(WebMergedContextConfiguration webMergedConfig)

Ensure that the supplied WebMergedContextConfiguration does not contain locations.

Overrides:

validateMergedContextConfiguration in class AbstractGenericWebContextLoader

Parameters:

webMergedConfig - the merged configuration to validate

Since:

4.0.4
