Question

我定义了一个方面，当在User对象上调用方法getFirstName（）时应该执行该方面。但它不会发生。

我的Aspect课程：

@Component
@Aspect
public class JpaGetFirstNameAspect {

  @Pointcut("execution(* de.playground.model.User.getFirstName(..))")
  public void pointCutSetFirstName() {
  }

  @Before("pointCutGetFirstName()")
  public void beforeGetFirstName(JoinPoint joinPoint) {
    System.out.println(">>>> Before retrieving first name ... " + joinPoint.getSignature().getName());  
  }

  @After("pointCutGetFirstName()")
  public void afterGetFirstName() {
    System.out.println(">>>> After execution of getFirstName method ... ");
  }

  @AfterReturning(pointcut = "pointCutGetFirstName()", returning = "firstName")
  public void afterReturningGetFirstName(JoinPoint joinPoint, String firstName) {
    System.out.println("<<<< " + joinPoint.getSignature().getName());
    System.out.println("<<<< returned first name of user " + firstName);
  }

 @AfterThrowing(pointcut = "pointCutGetFirstName()", throwing = "exc")
  public void afterThrowingGetFirstName(Exception exc) {
    System.out.println("|||| Retrieved Exception from getFirstName method ... " + exc.toString());
  }
}

我的application-context.xml：

<beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"        xmlns:tx="http://www.springframework.org/schema/tx"     xmlns:aop="http://www.springframework.org/schema/aop"

       ">

  <context:annotation-config />
  <context:load-time-weaver />
  <context:component-scan base-package="de.playground.service" />

</beans>

我的测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "file:src/test/resources/META-INF/spring/application-context.xml" })
public class AspectIntegrationTest {

  @Autowired
  private GenericApplicationContext context;

  private ClassPathXmlApplicationContext ctx;

  public AspectIntegrationTest() {

  }


  @AfterClass
  public static void tearDownClass() {

  }

  @BeforeClass
  public static void setUpClass() {
  }

  @Before
  public void setUp() throws Exception {
    ctx = new ClassPathXmlApplicationContext();
  }

  @After
  public void tearDown() {

  }

  @Test
  public void testHijackingUser() {

    User user1 = new User();
    user1.setCreatedOn(new Date());
    user1.setLastModified(new Date());
    user1.setFirstName("Max");
    user1.setLastName("Mustermann");
    user1.setUsername("max.mustermann");
    user1.setPassword("start123");
    System.out.println(">user 1 = " + user1.getFirstName());

    assertNotNull(user1);
  }
}

我的aop.xml：

<!DOCTYPE aspectj PUBLIC
    "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver options="-Xset:weaveJavaxPackages=true -verbose -showWeaveInfo">
        <!-- only weave classes in this package -->
        <include within="de.playground.service.*"     />  
    </weaver>
    <aspects>
        <!-- use only this aspect for weaving -->
        <aspect     name="de.playground.aspect.JpaGetFirstNameAspect" />
    </aspects>
</aspectj>
