### 有人想要Android面向切面编程,今天他来了!😜,轻松完成各种骚操作!登录状态拦截,日志拦截,权限拦截,轻松搞定!
https://github.com/TanZhiL/OkAspectj
更新日志：
v1.02 2019-10.17
- 第一次发布
快速对指定函数进行切面拦截：
- 注解完全自定义
- 拦截规则自定义
- 无需手动编写切面代码,APT自动生成切面文件
- 支持组件化
Installation：
1.project.gradle 添加(同步完成后再进行下一步!!!)
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(注意每个需要生成切面的文件的组件都需要添加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'
}

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

"-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()) {
case IMessage.ABORT:

log.error message.message, message.thrown
break;

break;
case IMessage.INFO:
log.info message.message, message.thrown
break;
case IMessage.DEBUG:
log.debug message.message, message.thrown

}
}
}
}

Usage：
- 在自己想要拦截的注解之上添加 @OkAspectj注解
@OkAspectj
@Target(ElementType.METHOD)
public @interface NeedLogin {
int value()default 0;
}
- 在想要拦截的方法加入自己的注解
@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设置全局切面拦截处理
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)中自由发挥你的骚操作了!
5.也可自己编写切面文件,然后通过调用OkAspectjHelper.notifyHandler(Class clazz,ProceedingJoinPoint joinPoint),发送切点信息进行统一处理.
