use of org.springframework.stereotype.Component in project spring-framework by spring-projects.

the class AnnotationUtilsTests method synthesizeAnnotationFromAnnotationAttributesWithoutAttributeAliases.

@Test

    assertNotNull(component);
    // 2) Convert the annotation into AnnotationAttributes
    AnnotationAttributes attributes = getAnnotationAttributes(WebController.class, component);

    // 3) Synthesize the AnnotationAttributes back into an annotation
    Component synthesizedComponent = synthesizeAnnotation(attributes, Component.class, WebController.class);
    assertNotNull(synthesizedComponent);
    // 4) Verify that the original and synthesized annotations are equivalent
    assertNotSame(component, synthesizedComponent);
    assertEquals(component, synthesizedComponent);
