有如下两个切点：

@Pointcut("execution(public * com.wyh.data.controller.DepartmentController.*(..))")
public void department(){}
@Pointcut("execution(public * com.wyh.data.controller.UserController.*(..))")
public void user(){}

@Before("department()")//怎样在这里指定多个切点，逗号不可以
public void before(JoinPoint joinPoint){do something}

此时可以这么写

@Before("department()||user()")
public void before(JoinPoint joinPoint){do something}
