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!

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

    buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
      
        classpath 'org.aspectj:aspectjtools:1.9.6'
        classpath 'com.github.TanZhiL.OkAspectj:okaspectj-plugin:+'
    }
}

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)

apply plugin: 'com.xtc.thomas.okaspectj'

dependencies {
     implementation 'org.aspectj:aspectjrt:1.9.6'
     implementation 'com.github.TanZhiL.OkAspectj:okaspectj:+'
     annotationProcessor 'com.github.TanZhiL.OkAspectj:okaspectj-compiler:+'
}

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;
}
  1. 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.init(new PointHandler() {
            @Override
            public void onHandlePoint(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onHandlePoint(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.

6.拦截系统方法请参考以下案例.

经典案例:

1.点击事件

@OkAspectj("execution(* android.view.View.OnClickListener.onClick(..))")
@Target(ElementType.METHOD)
public @interface TestClick {
}

2.生命周期

@OkAspectj("execution(* android.app.Activity.on**(..))")
@Target(ElementType.METHOD)
public @interface TestLifeCycle {
}

配置出错的请参考 高仿喜马拉雅听Android客户端 https://github.com/TanZhiL/Zhumulangma
