用法

1. 完整写法：

　

@Pointcut("execution(* com.brothergang.demo.aop.TestActivity.onCreate(..)) ||"
            + "execution(* com.brothergang.demo.aop.TestActivity.onStart(..)) ||"
            + "execution(* com.brothergang.demo.aop.TestActivity.onResume(..)) ||"
            + "execution(* com.brothergang.demo.aop.TestActivity.onDestroy(..)) ||"
            + "execution(* com.brothergang.demo.aop.TestActivity.onPause(..))"
    )
    public void logForActivity() {
    }
    //注意，这个函数必须要有实现，否则Java编译器会报错

    /*
    @Before：这就是Before的advice，对于after，after -returning，和after-throwing。对于的注解格式为
    @After，@AfterReturning，@AfterThrowing。Before后面跟的是pointcut名字，然后其代码块由一个函数来实现。
            比如此处的log。
    */
    @Before("logForActivity()")
    public void log(JoinPoint joinPoint) {
        String tag = ((TestActivity) joinPoint.getTarget()).tag;
        Log.e(TAG, "AOP 埋点：" + joinPoint.toShortString() + "==" + tag);
    }

 

2. 精简写法

/**
     * 精简写法
     */
    @Around("execution(* android.view.View.OnClickListener.onClick(..))")
    public void logClickEvent(ProceedingJoinPoint joinPoint) {
        Log.e(TAG, "AOP 埋点：" + joinPoint.toShortString());
        try {
            joinPoint.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }

 

3.获取参数

private void debugLog(String loginfo) {
        LogUtils.i(this.getClass(), loginfo);
    }

 

@Around("execution(* debugLog(..))")
    public void debugLog(ProceedingJoinPoint joinPoint) {
//        joinPoint.getArgs()   //获取getargs 获取参数
        Log.e(TAG, "AOP 埋点：" + joinPoint.toShortString());
        try {
            joinPoint.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }

 

4. 获取Annatation参数

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface MyAnnatation {
    String value() default "code";
}

@MyAnnatation(value = "ourself")
    private void aopAnnatation() {
        LogUtils.i(this.getClass(), "11111111111");
    }

@Around("execution(* aopAnnatation(..))&&@annotation(params)")
    public void aopAnnatation(ProceedingJoinPoint joinPoint, MyAnnatation params) {
//        joinPoint.getArgs()   //获取getargs 获取参数
        Log.e(TAG, "AOP 埋点：" + joinPoint.toShortString() + "--" + params.value().toString());
        try {
            joinPoint.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }
