extjs tree panel,树显示时默认查询一级节点,树未显示时调用tree.expandAll();将报错
session.createQuery(hql).uniqueResult();
spring 通知:
@Before("anyMethod() && args(name)") //前置通知
public void doBefore(String name) {}
@AfterReturning(pointcut="andMethod()", returning="result") //后置通知
public void doAfterReturning(String result) {}
@After(""); //最终通知
@AfterThrowing(pointcut="andMethod()", throwing="e") //例外通知
public void doAfterThrowing(Exception e) {}
@Around("") //环绕通知
public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
Object result = pjp.proceed(); //执行目标方法
return result;
}
例外通知和最终通知的执行顺序与注解或xml配置的先后顺序有关?
