（4.6.23.3）Android之面向切面编程：Aspect示例之继承关系测试

1. JoinPoint获取的参数是值or引用

目标为：checkInput(int i,StringBuilder stringBuilder )函数
说明：函数执行期间修改参数
测试：参数是基本类型则为值传递；对象则为引用传递

        int i = 1;        StringBuilder stringBuilder = new StringBuilder("a");        checkInput(i, stringBuilder);    private void checkInput(int i,StringBuilder stringBuilder ) {        i=2;        stringBuilder.append("b");    }

    /***     * 获取函数的输入参数     * 证明：拿到的就是输入值的地址     * 如果是值传递，则不会干扰，也就是说，函数体内修改后，after之后还是原来的值；     * 引用传递会干扰；     */    public static final String TAG_CHECKINPUT = "CheckInput";    @Before("execution(* sangfor.com.aop.activity.MainActivity.checkInput(..))")    public void methodBeforecheckInput(JoinPoint joinPoint) throws Throwable {        String key = joinPoint.getSignature().toString();        Log.d("MainActivity", "methodBeforecheckInput: " + key);        for (int i = 0; i < joinPoint.getArgs().length; i++) {            //两个参数  一个是值传递  一个是引用传递            Log.d(TAG_CHECKINPUT, "methodBeforecheckInput():" + joinPoint.getArgs()[i].toString());        }    }    @After("execution(* sangfor.com.aop.activity.MainActivity.checkInput(..))")    public void methodAftercheckInput(JoinPoint joinPoint) throws Throwable {        for (int i = 0; i < joinPoint.getArgs().length; i++) {            //两个参数  一个是值传递  一个是引用传递            Log.d(TAG_CHECKINPUT, "methodAftercheckInput():"+joinPoint.getArgs()[i].toString());        }    }

2. execution 与 call的不同

call是调用位置
execution 是函数位置

    public void testAOP() {        Log.d("MainActivity", "testAOP");    }

    /***     * execution 与 call的不同     */    public static final String TAG_CHECKEC = "CheckExceAndCall";    @Before("execution(* sangfor.com.aop.activity.MainActivity.testAOP(..))")    public void methodExecutionAOPTest(JoinPoint joinPoint) throws Throwable {        String key = joinPoint.getSignature().toString();        Log.d(TAG_CHECKEC, "methodExecutionAOPTest: "                + "\n Signature-" +key                + "\n SignatureDeclaringTypeName-" + joinPoint.getSignature().getDeclaringTypeName()                + "\n SignatureDeclaringType-" + joinPoint.getSignature().getDeclaringType()                + "\n SignatureName-" + joinPoint.getSignature().getName()                + "\n SourceLocation-" + joinPoint.getSourceLocation()                + "\n SourceLocationFileName-" + joinPoint.getSourceLocation().getFileName()                + "\n SourceLocationLine-" + joinPoint.getSourceLocation().getLine()                + "\n SourceLocationWithinType-" + joinPoint.getSourceLocation().getWithinType()                + "\n Target-" + joinPoint.getTarget()                + "\n This-" + joinPoint.getThis()                + "\n Kind-" + joinPoint.getKind());    }    @Before("call(* sangfor.com.aop.activity.MainActivity.testAOP(..))")    public void methodCallAOPTest(JoinPoint joinPoint) throws Throwable {        String key = joinPoint.getSignature().toString();        Log.d(TAG_CHECKEC, "methodExecutionAOPTest: "                + "\n Signature-" +key                + "\n SignatureDeclaringTypeName-" + joinPoint.getSignature().getDeclaringTypeName()                + "\n SignatureDeclaringType-" + joinPoint.getSignature().getDeclaringType()                + "\n SignatureName-" + joinPoint.getSignature().getName()                + "\n SourceLocation-" + joinPoint.getSourceLocation()                + "\n SourceLocationFileName-" + joinPoint.getSourceLocation().getFileName()                + "\n SourceLocationLine-" + joinPoint.getSourceLocation().getLine()                + "\n SourceLocationWithinType-" + joinPoint.getSourceLocation().getWithinType()                + "\n Target-" + joinPoint.getTarget()                + "\n This-" + joinPoint.getThis()                + "\n Kind-" + joinPoint.getKind());    }

hook基类，基类被锁定，子类是否也满足 切入点

是
我们目标为Activity的on方法，所有继承自Activity + 调用了super.的都触发了 切面程序
