是否可以在 Android Studio 项目中集成 Dagger 和 AspectJ？

Question

我正在使用 Dagger 进行依赖注入的 Android 项目。我对 Gradle 了解不多，但据我了解，Dagger 注释在项目构建后由其编译器处理。正如用户指南所说，配置它没有问题。嗯，现在我也想集成AspectJ，所以我在看one of the plugins for Android。

然而，这个插件似乎也做了一个构建后处理工作来读取方面，这仍然与 Dagger 编译器所做的冲突。这是我当前的 build.gradle 文件（构建一个测试项目以拥有SSCCE）：

apply plugin: 'com.android.application'

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
        classpath 'com.uphyca.gradle:gradle-android-aspectj-plugin:0.9.9'
    }
}

apply plugin: 'android-aspectj'

android {
    compileSdkVersion 20
    buildToolsVersion "20"

    defaultConfig {
        minSdkVersion 12
        targetSdkVersion 20
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:20.+'
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'com.squareup.dagger:dagger:1.2.2'
    provided 'com.squareup.dagger:dagger-compiler:1.2.2'
}

以及使用的方面：

@Aspect
public class HelloAspect {
    @Around("execution(void com.mycompany.test.MainActivity.test())")
    public void around(ProceedingJoinPoint pj) throws Throwable {
        Log.d("Prueba","Hello, @Aspect");
    }
}

这就是抛出的异常：

AspectJ 似乎无法编织HelloAspect 的属性。实际上，看起来文件本身找不到（File was :<Unknown>::0）。那么... AspectJ 可以完全与 Dagger 一起使用吗？单独使用时我没有问题。

Answer 1

看起来你想使用运行时编织，但我知道 Dalvik 不支持这个，所以你应该改变你的 gradle 脚本来获得 AspectJ 编译时编织，在这里你可以找到两个解决方案：

• http://fernandocejas.com/2014/08/03/aspect-oriented-programming-in-android/

Answer 2

我已经完成了这项工作，但在这个阶段仍将被视为“黑客”，因为您不能简单地按下“运行”按钮来安装一个编织匕首注入的应用程序。这是我在尝试恢复我的 Spring 时发现的 - 类似于 @Transactional 数据库事务创建切入点。

遵循SO response 的建议，并将手动 AspectJ 部分添加到您的应用程序的build.gradle。尝试运行该项目，我的项目编译和安装正常，但随后因疏通而失败；

“请确保已在此模块上运行代码生成”

...Dagger 生成的错误。怀疑是在更改 .class 字节码之前清空了 dagger 创建的 /gen 文件夹的编织，我注释掉了该行；

应用插件：'android-aspectj'

...并重新运行应用程序而不进行任何代码更改。令我惊讶的是，维护了第一次尝试生成的编织类，然后附加了 dagger 模块指令！这具有保留 AspectJ 生成的代码并覆盖 Dagger 模块指令的效果！成功？有点......显然存在一个冲突（可能是围绕“gen”文件夹的清理），我将寻求下一步克服。但是，这很重要，但是，我正在运行一个带有 AspectJ AOP 代码的应用程序，该代码使用 Dagger 进行 DI...进展...
