基于 Aspecj 实现的 Android AOP 框架，并使用沪江的gradle 插件：https://github.com/HujiangTechnology/gradle_plugin_android_aspectjx
在根目录下的build.gradle中添加
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.hujiang.aspectjx:gradle-android-plugin-aspectjx:2.0.4'
}
}在app 模块目录下的build.gradle中添加
apply plugin: 'com.hujiang.android-aspectjx'
...
dependencies {
compile 'com.safframework:saf-aop:1.3.0'
...
}基于aspectj的AOP，无需使用耗费性能的反射.不过,需要在build.gradle中配置一下aspectj
| 注解名称 | 作用 | 备注 |
|---|---|---|
| @Async | 借助RxJava,异步地执行app中的方法 | |
| @Cacheable | Spring Cache风格的Cache注解,将结果放于缓存中 | 只适用于android4.0以后 |
| @LogMethod | 将方法的入参和出参都打印出来,可以用于调试 | |
| @HookMethod | 可以在调用某个方法之前、以及之后进行hook | 比较适合埋点的场景，可以单独使用也可以跟任何自定义注解配合使用。也支持在匿名内部类中使用 |
| @Prefs | 将方法返回的结果放入AppPrefs中 | 只适用于android4.0以后 |
| @Safe | 可以安全地执行方法,而无需考虑是否会抛出运行时异常 | 支持在捕获异常的时候进行监听 |
| @Trace | 用于追踪某个方法花费的时间,可以用于性能调优的评判 | 支持追踪匿名内部类中的方法 |
| @Permission | 可用于运行时动态地申请权限 |
@Async
private void useAsync() {
Log.e(TAG, " thread=" + Thread.currentThread().getId());
Log.e(TAG, "ui thread=" + Looper.getMainLooper().getThread().getId());
} @Cacheable(key = "user")
private User initData() {
User user = new User();
user.userName = "tony";
user.password = "123456";
return user;
}这里的@Cacheable,实际上用到Cache,要获取Cache也很简单.
@Trace
@Async
private void loadUser() {
Log.e(TAG, " thread=" + Thread.currentThread().getId());
Log.e(TAG, "ui thread=" + Looper.getMainLooper().getThread().getId());
Cache cache = Cache.get(this);
User user = (User) cache.getObject("user");
Toast.makeText(MainActivity.this, SAFUtils.printObject(user), Toast.LENGTH_SHORT).show();
}将@Trace和@Async两个注解结合使用,可以看到调用loadUser()方法花费的时间.

05-18 14:31:31.231 21190-22033/app.magicwindow.cn.testsaf E/com.test.saf.activity.MainActivity: ui thread=1@Trace还支持在匿名内部类中使用
@Trace
private void initData() {
Observable.create(new ObservableOnSubscribe<String>() {
@Trace
@Override
public void subscribe(@NonNull ObservableEmitter<String> e) throws Exception {
e.onNext("111");
e.onNext("222");
e.onNext("333");
}
}).subscribe(new Consumer<String>() {
@Trace
@Override
public void accept(@NonNull String str) throws Exception {
}
});
}不写beforeMethod和afterMethod，则相当于没有使用@HookMethod
beforeMethod和afterMethod对应的都是方法名，分别表示在调用doSomething()之前执行和之后执行。目前还不支持在beforeMethod和afterMethod中传递参数。
@HookMethod(beforeMethod="dosthbeforeMethod",afterMethod="dosthafterMethod")
void doSomething() {
}@HookMethod 同样支持在匿名内部类中使用
@HookMethod(beforeMethod = "method1",afterMethod = "method2")
private void initData() {
L.i("initData()");
}
private void method1() {
L.i("method1() is called before initData()");
}
private void method2() {
L.i("method2() is called after initData()");
}
private void testRx() {
Observable.just("tony")
.subscribe(new Consumer<String>() {
@HookMethod(beforeMethod = "testRxBefore")
@Override
public void accept(@NonNull String s) throws Exception {
System.out.println("s="+s);
}
private void testRxBefore() {
L.i("testRxBefore() is called before accept()");
}
