Tracing.aj

Hook 类构造方法通过反射修改实例属性类名会变
----
package aop;

import java.lang.reflect.Field;

aspect Tracing {
    after() : initialization(dgh.b.new(..)) {
        try {
            Object target = thisJoinPoint.getTarget();
            Field field = target.getClass().getDeclaredField("a");
            field.setAccessible(true);
            field.setBoolean(target, false);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Hook 类库方法
----
package aop;

aspect Tracing {
    boolean around(String str): call(boolean joptsimple.OptionSet.has(String)) && args(str) {
        if(str == "demo") {
            return false;
        } else {
            return proceed(str);
        }
    }
}
