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'
}

Usage：

1. 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;
}

2. 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.
