### 有人想要Android面向切面編程,今天他來了!😜,輕鬆完成各種騷操作!登錄狀態攔截,日誌攔截,權限攔截,輕鬆搞定!
https://github.com/TanZhiL/OkAspectj
更新日誌：
v1.02 2019-10.17
- 第一次發佈
快速對指定函數進行切面攔截：
- 註解完全自定義
- 攔截規則自定義
- 無需手動編寫切面代碼,APT自動生成切面文件
- 支持組件化
Installation：
1.project.gradle 添加(同步完成後再進行下一步!!!)
buildscript {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'org.aspectj:aspectjtools:1.8.9'
classpath 'org.aspectj:aspectjweaver:1.8.9'
}
}
2.app.gradle 添加(注意每個需要生成切面的文件的組件都需要添加annotationProcessor)
dependencies {
implementation 'org.aspectj:aspectjrt:1.8.14'
implementation 'com.github.TanZhiL:OkAspectjAnnotation:1.0.4'
annotationProcessor 'com.github.TanZhiL:OkAspectjCompiler:1.0.4'
}

variants.all { variant ->
if (!variant.buildType.isDebuggable()) {
log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.")
return;
}
JavaCompile javaCompile = variant.javaCompile
javaCompile.doLast {

"-aspectpath", javaCompile.classpath.asPath,
"-d", javaCompile.destinationDir.toString(),
"-classpath", javaCompile.classpath.asPath,
"-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]
log.debug "ajc args: " + Arrays.toString(args)
MessageHandler handler = new MessageHandler(true);
new Main().run(args, handler);
for (IMessage message : handler.getMessages(null, true)) {
switch (message.getKind()) {

}
}
}

}

Usage：
- 在自己想要攔截的註解之上添加 @OkAspectj註解
@OkAspectj
@Target(ElementType.METHOD)
public @interface NeedLogin {
int value()default 0;
}
- 在想要攔截的方法加入自己的註解
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
test();
test1();
}
@NeedLogin(2)
private void test() {
}
@TestAnnotaion
private void test1() {
}
}
3.在Application設置全局切面攔截處理
public class App extends Application {
private static final String TAG = "App";
@Override
public void onCreate() {
super.onCreate();
OkAspectjHelper.setmHandler(new PointHandler() {
@Override
public void handlePoint(Class clazz, ProceedingJoinPoint joinPoint) {
Log.d(TAG, "handlePoint() called with: clazz = [" + clazz + "]");
if(clazz==NeedLogin.class){
MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
NeedLogin annotation = methodSignature.getMethod().getAnnotation(NeedLogin.class);
Log.d(TAG, "handlePoint() called with: joinPoint = [" + annotation.value() + "]");
try {
joinPoint.proceed();
} catch (Throwable throwable) {
throwable.printStackTrace();
}
}
}
});
}
}
4.配置完成,可以在handlePoint(Class clazz, ProceedingJoinPoint joinPoint)中自由發揮你的騷操作了!
5.也可自己編寫切面文件,然後通過調用OkAspectjHelper.notifyHandler(Class clazz,ProceedingJoinPoint joinPoint),發送切點信息進行統一處理.
