Question

我的建议正确执行并执行正确的操作，但执行两次除外。我希望它只执行一次。由于startTestSuite标题仅在日志中打印一次，因此应该触发建议的方法仅执行一次。 Bean和上下文是在TestNG类中生成的。我尝试在initSpring（）方法上使用@BeforeClass和@BeforeSuite标记运行它，结果相同。
进一步背景：这样做的目的是获得测试套件启动和结束时间的时间戳，并获得各个测试开始和结束时间的时间戳。最终，我将捕获测试失败时的堆栈跟踪，以便我们可以构建测试自动化问题最多的模式，并允许我们将精力集中在需要修复的更重要的自动化领域而不是修理琐碎的事情。

TestNG Class

public class BVT extends SeleniumTest {    
@BeforeSuite
        public void initSpring() {
            titleLog.testTitle("initSpring");
            context = new FileSystemXmlApplicationContext(new String[]{"spring-beans.xml"});
            Assert.assertNotNull(context, "Unable to load spring-beans.xml");
            logger.info("context object instantiated");
            context.registerShutdownHook();
            logger.info("Shutdown hook registered");
            instrument = (Instrumentation) context.getBean("InstrumentationProxy");
            Assert.assertNotNull(instrument, "Unable to create a Instrumentation Proxy");
            logger.info("Obtained a Instrumentation proxy");
            instrument.startTestSuite();
            logger.info("Called the Proxy");
        }
}

代理接口

public interface Instrumentation {
    public void startTestSuite();
}

被叫代理方法

@Override
    public void startTestSuite() {
        logger.info("Going to print the title: startTestSuite");
        titleLog.testTitle("startTestSuite");   
    }

建议

@Override
    @Before("execution(void test.ui.tests.InstrumentationImpl.startTestSuite())")
    public void beforeTestSuite(JoinPoint jp) {
        logger.info("***************Running Advice: " + jp.getSignature().getName());
        DateTimeHelper dth = new DateTimeHelper();
        TestSuite ts = new TestSuite();

        //Get the current time
        Timestamp start = dth.getCurrentSqlTimestamp();

        //Update the object with the starting time
        ts.setTestSuiteStart(start);

        //Commit to the database
        saveTestSuite(ts);  
    }

更新：我将我的切入点改为此（Insturmentation vs InstrumentationImpl）并且它被触发了四次。

 @Before("execution(void test.ui.tests.Instrumentation.startTestSuite())")

以下是添加了jp.getTarget（）。toString（）的日志。

Answer 1

如果没有更多的背景，很难说这里发生了什么，但我的猜测是你的方面已经被注册了两次。

为什么我的AspectJ建议被执行两次？
