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

Question

我正在一個Android項目中工作，我正在使用Dagger進行依賴注入。 我對Gradle知之甚少，但就我所知，Dagger注釋在構建項目后由其編譯器處理。 用戶指南說，配置它沒有問題。 好吧，現在我也想集成AspectJ，所以我正在尋找Android的一個插件 。

但是，看起來這個插件做了一個構建后期處理工作來讀取方面，這仍然與Dagger編譯器的工作相沖突。 這是我當前的build.gradle文件（構建了一個具有SSCCE的測試項目）：

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'
}

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");
    }
}

這是拋出的異常：

似乎AspectJ無法編織HelloAspect的屬性。 實際上，看起來無法找到文件本身（ File was :<Unknown>::0 ）。 那么...... AspectJ可以和Dagger一起使用嗎？ 單獨使用時我沒有問題。

我的測試項目在一個zip文件中

Answer 1

看起來你想要使用運行時編織，但是我知道Dalvik不支持這個，所以你應該改變你的gradle腳本來獲得AspectJ編譯時編織，在這里你可以找到兩個解決方案：

Answer 2

我有這個工作，但在這個階段仍然被認為是“黑客”，因為你不能簡單地按“運行”按鈕來安裝一個編織的匕首注入的應用程序。 這是我在嘗試恢復@Transactional Spring的@Transactional數據庫事務創建切入點時發現的。

遵循此SO響應的建議，並將手冊AspectJ部分添加到應用程序的build.gradle 。 嘗試運行項目，我的項目編譯和安裝正常但隨后失敗了與dredded;

“請確保已在此模塊上運行代碼生成”

...... Dagger產生的錯誤。 懷疑是在更改.class字節碼之前編織清空dagger創建的/gen文件夾我注釋掉了這行;

apply plugin：'android-aspectj'

...並重新運行應用程序而不進行任何代碼更改 。 令我驚訝的是，第一次嘗試中生成的編織類被維護，然后附加了匕首模塊指令！ 這樣可以保持AspectJ生成的代碼並覆蓋Dagger模塊指令！ 成功？ 有點......顯然存在沖突（可能圍繞“gen”文件夾的清理）我接下來要克服。 但是，這是一個重要的但是，我運行的應用程序使用AspectJ AOP代碼，使用Dagger進行DI ...進度...
