春季AOP不能正常工作

Question

我是新來的春天aop。我有以下課程。 1.接口

public interface AccountService { 

public void transferMoney(
     long sourceAccountId, long targetAccountId, double amount); 

public void depositMoney(long accountId, double amount) throws Exception; 

public Account getAccount(long accountId); 

} 

2.方面類 @Aspect 公共類TimeAOP { 長開始時間= 0;

@Pointcut("execution(* *.transferMoney(..))")// the pointcut expression 
private void anyOldTransfer() {}// the pointcut signature 

@After("anyOldTransfer()") 
public void afterReturning(Object returnValue, Method method, Object[] args, Object target) throws Throwable { 
    long elapsedTime = System.nanoTime() - startTime; 
    String className = target.getClass().getCanonicalName(); 
    String methodName = method.getName(); 
    System.out.println("Execution of " + className + "#" + methodName 
      + " ended in " + new BigDecimal(elapsedTime).divide(
      new BigDecimal(1000000)) + " milliseconds"); 

} 

@Before("anyOldTransfer()") 
public void before(Method method, Object[] args, Object target) throws Throwable { 
    System.out.println("Starting"); 
    startTime = System.nanoTime(); 
} 

}

3.配置類

@Configuration 
@EnableAspectJAutoProxy 
@ComponentScan(basePackages = "com.xxx") 
public class Ch2BeanConfiguration { 
@Bean 
public AccountService accountService() { 
    AccountServiceImpl bean = new AccountServiceImpl(); 
    bean.setAccountDao(accountDao()); 
    return bean; 
} 

@Bean 
public AccountDao accountDao() { 
    AccountDaoInMemoryImpl bean = new AccountDaoInMemoryImpl(); 
    //depedencies of accountDao bean will be injected here... 
    return bean; 
} 
} 

4.測試類

public class Main { 
public static void main(String[] args){ 
    AnnotationConfigApplicationContext applicationContext = 
      new AnnotationConfigApplicationContext(Ch2BeanConfiguration.class); 
    AccountService accountService = applicationContext.getBean("accountService", 
      AccountService.class); 
    System.out.println("Before money transfer"); 
    System.out.println("Account 1 balance :" + accountService.getAccount(1).getBalance()); 
    System.out.println("Account 2 balance :" + accountService.getAccount(2).getBalance()); 
    accountService.transferMoney(1, 2, 5.0); 
    System.out.println("After money transfer"); 
    System.out.println("Account 1 balance :" + accountService.getAccount(1).getBalance()); 
    System.out.println("Account 2 balance :" + accountService.getAccount(2).getBalance()); 
} 
} 

輸出： 2016年3月6日下午12時27分05秒org.springframework.context.annotation.AnnotationConfigApplicationContext prepareRefresh 信息：刷新org.springframework.context.annotation.AnnotationConfigApplicationContext@5d099f62：啓動日期[太陽Mar 06 12:27:05 EST 2016];上下文結構 根匯款 賬戶餘額1之前：10.0 賬戶餘額2：20.0 匯款 賬戶餘額1後：5.0 賬戶餘額2：25.0

的AOP是永遠不會執行。任何人都可以幫助我？

Answer 1

既然你不使用你需要從@Configuration返回一個看點豆XML

@Bean 
public TimeAOP timeAspect() { 
    return new TimeAOP(); 
}
