Examples with ParameterResolutionDelegate - org.springframework.beans.factory.annotation.ParameterResolutionDelegate

Example 1 with ParameterResolutionDelegate

use of org.springframework.beans.factory.annotation.ParameterResolutionDelegate in project spring-framework by spring-projects.

the class SpringExtension method supportsParameter.

/**
 * Determine if the value for the {@link Parameter} in the supplied {@link ParameterContext}
 * should be autowired from the test's {@link ApplicationContext}.
 * <p>A parameter is considered to be autowirable if one of the following
 * conditions is {@code true}.
 * <ol>
 * <li>The {@linkplain ParameterContext#getDeclaringExecutable() declaring
 * executable} is a {@link Constructor} and
 * {@link TestConstructorUtils#isAutowirableConstructor(Constructor, Class, PropertyProvider)}
 * returns {@code true}. Note that {@code isAutowirableConstructor()} will be
 * invoked with a fallback {@link PropertyProvider} that delegates its lookup
 * to {@link ExtensionContext#getConfigurationParameter(String)}.</li>
 * <li>The parameter is of type {@link ApplicationContext} or a sub-type thereof.</li>
 * <li>The parameter is of type {@link ApplicationEvents} or a sub-type thereof.</li>
 * <li>{@link ParameterResolutionDelegate#isAutowirable} returns {@code true}.</li>
 * </ol>
 * <p><strong>WARNING</strong>: If a test class {@code Constructor} is annotated
 * with {@code @Autowired} or automatically autowirable (see {@link TestConstructor}),
 * Spring will assume the responsibility for resolving all parameters in the
 * constructor. Consequently, no other registered {@link ParameterResolver}
 * will be able to resolve parameters.
 * @see #resolveParameter
 * @see TestConstructorUtils#isAutowirableConstructor(Constructor, Class)
 * @see ParameterResolutionDelegate#isAutowirable
