您好,登錄后才能下訂單哦!
昨天看了一段android配置aspectj實現AOP的直播視頻,就試著自己配置了一下,可能是因為我自己的AndroidStudio環境的問題,碰到了不少的坑(其實還是因為對gradle理解的不多),但總歸是配置好了,就分享一下。
試了兩種方式,不過項目下的build.gradle,沒什么變化,直接看一下代碼吧:
build.gradle(項目下)
buildscript { ext { //android appcompat支持庫版本 androidSupportVersion = '26.1.0' //編譯的 SDK 版本,如API20 compileSdkVersion = 26 //構建工具的版本,其中包括了打包工具aapt、dx等,如API20對應的build-tool的版本就是20.0.0 buildToolsVersion = "26.0.2" //兼容的最低 SDK 版本 minSdkVersion = 15 //向前兼容,保存新舊兩種邏輯,并通過 if-else 方法來判斷執行哪種邏輯 targetSdkVersion = 26 //kotlin版本號 kotlin_version = '1.2.10' kotlinVersion = "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" appcompatV7 = "com.android.support:appcompat-v7:$androidSupportVersion" appcompatDesign = "com.android.support:design:$androidSupportVersion" constraintLayout = 'com.android.support.constraint:constraint-layout:1.0.2' } repositories { google() jcenter() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" classpath 'org.greenrobot:greendao-gradle-plugin:3.2.1' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files classpath 'org.aspectj:aspectjtools:1.8.13' classpath 'org.aspectj:aspectjweaver:1.8.13' } } allprojects { repositories { google() jcenter() mavenCentral() } } task clean(type: Delete) { delete rootProject.buildDir }
看著一大堆,主要就是下面這幾行配置,其他的是我自己項目中用到的,根據自己需要配置就行。
buildscript { repositories { mavenCentral() } dependencies { classpath 'org.aspectj:aspectjtools:1.8.13' classpath 'org.aspectj:aspectjweaver:1.8.13' } } repositories { mavenCentral() }
其實這幾行配置在app的build.gradle里也是可以的,但是因為項目下的build.gradle里已經有buildscript {}、allprojects {repositories{} },就配置在這里了。
然后有兩種配置方式:
第一種
只有一個主Module app的情況下,配置app的build.gradle:
apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' apply plugin: 'org.greenrobot.greendao' android { compileSdkVersion rootProject.ext.compileSdkVersion buildToolsVersion rootProject.ext.buildToolsVersion defaultConfig { applicationId "填入自己的applicationId" minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion versionCode 1 versionName "1.0" //Lambda配置 // jackOptions.enabled = true // android.compileOptions.sourceCompatibility 1.8 buildConfigField "boolean", "LOG", "true"http:// 顯示Log testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" //支持矢量圖 vectorDrawables.useSupportLibrary = true ndk { //選擇要添加的對應cpu類型的.so庫。 abiFilters 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64', 'mips', 'mips64' } } buildTypes { release { minifyEnabled false buildConfigField "boolean", "LOG", "false"http:// 顯示Log proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } //Lambda配置 compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } dataBinding { enabled true } greendao { schemaVersion 1//數據庫版本號 daoPackage 'com.test.qby.newtestapplication.greendao'//設置DaoMaster、DaoSession、Dao包名 targetGenDir 'src/main/java'//設置DaoMaster、DaoSession、Dao目錄 //targetGenDirTest:設置生成單元測試目錄 //generateTests:設置自動生成單元測試用例 } lintOptions { abortOnError true } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation rootProject.ext.kotlinVersion implementation rootProject.ext.appcompatV7 implementation rootProject.ext.constraintLayout compile rootProject.ext.appcompatDesign testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' compile 'jp.wasabeef:glide-transformations:3.0.1' // If you want to use the GPU Filters compile 'jp.co.cyberagent.android.gpuimage:gpuimage-library:1.4.1' //騰訊bugly compile 'com.tencent.bugly:crashreport:latest.release' compile 'com.tencent.bugly:nativecrashreport:latest.release' //retrofit compile 'com.squareup.retrofit2:retrofit:2.3.0' compile 'com.squareup.retrofit2:converter-gson:2.3.0' compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' compile 'com.squareup.okhttp3:logging-interceptor:3.9.0' //rxJava compile 'io.reactivex.rxjava2:rxandroid:2.0.1' // Because RxAndroid releases are few and far between, it is recommended you also // explicitly depend on RxJava's latest version for bug fixes and new features. compile 'io.reactivex.rxjava2:rxjava:2.1.8' //greenDao compile 'org.greenrobot:greendao:3.2.0' //換膚功能 compile 'com.zhy:changeskin:4.0.2' //AOP面向切面編程,加入這行就不用在libs下引入jar包了,不然要寫成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13' } /* //在項目下配置了,此處就不需要了 buildscript { repositories { mavenCentral() } dependencies { classpath 'org.aspectj:aspectjtools:1.8.13' classpath 'org.aspectj:aspectjweaver:1.8.13' } } repositories { mavenCentral() } */ import org.aspectj.bridge.IMessage import org.aspectj.bridge.MessageHandler import org.aspectj.tools.ajc.Main final def log = project.logger final def variants = project.android.applicationVariants variants.all { variant -> if (!variant.buildType.isDebuggable()) { log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.") return } JavaCompile javaCompile = variant.javaCompile javaCompile.doLast { String[] args = ["-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), "-aspectpath", javaCompile.classpath.asPath, "-d", javaCompile.destinationDir.toString(), "-classpath", javaCompile.classpath.asPath, "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)] log.debug "ajc args: " + Arrays.toString(args) MessageHandler handler = new MessageHandler(true) new Main().run(args, handler) for (IMessage message : handler.getMessages(null, true)) { switch (message.getKind()) { case IMessage.ABORT: case IMessage.ERROR: case IMessage.FAIL: log.error message.message, message.thrown break case IMessage.WARNING: log.warn message.message, message.thrown break case IMessage.INFO: log.info message.message, message.thrown break case IMessage.DEBUG: log.debug message.message, message.thrown break } } } }
這一個gradle主要的東西就是這些:
//AOP面向切面編程,加入這行就不用在libs下引入jar包了,不然要寫成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13' import org.aspectj.bridge.IMessage import org.aspectj.bridge.MessageHandler import org.aspectj.tools.ajc.Main final def log = project.logger final def variants = project.android.applicationVariants variants.all { variant -> if (!variant.buildType.isDebuggable()) { log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.") return } JavaCompile javaCompile = variant.javaCompile javaCompile.doLast { String[] args = ["-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), "-aspectpath", javaCompile.classpath.asPath, "-d", javaCompile.destinationDir.toString(), "-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: case IMessage.ERROR: case IMessage.FAIL: log.error message.message, message.thrown break case IMessage.WARNING: log.warn message.message, message.thrown break case IMessage.INFO: log.info message.message, message.thrown break case IMessage.DEBUG: log.debug message.message, message.thrown break } } } }
下面那一堆是用命令在編譯最后做一些關聯的,具體的我也不懂,只管加上好了。
第二種
有多個module都需要用到aspectj,特別是組件開發的情況下,不可能每個module都配置一下,所以就需要新建一個aspectj的module作為項目的library。
app下build.gradle需要修改:
將
//AOP面向切面編程,加入這行就不用在libs下引入jar包了,不然要寫成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13'
去掉,改為
implementation project(':aspectjlib')
不過上面這句在你添加module依賴的時候會自動生成。
新建library的build.gradle配置如下:
apply plugin: 'com.android.library' android { compileSdkVersion rootProject.ext.compileSdkVersion buildToolsVersion rootProject.ext.buildToolsVersion defaultConfig { minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation rootProject.ext.appcompatV7 testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' //AOP compile 'org.aspectj:aspectjrt:1.8.13' } import org.aspectj.bridge.IMessage import org.aspectj.bridge.MessageHandler import org.aspectj.tools.ajc.Main android.libraryVariants.all { variant -> JavaCompile javaCompile = variant.javaCompile javaCompile.doLast { String[] args = ["-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), "-aspectpath", javaCompile.classpath.asPath, "-d", javaCompile.destinationDir.toString(), "-classpath", javaCompile.classpath.asPath, "-bootclasspath", android.bootClasspath.join( File.pathSeparator)] MessageHandler handler = new MessageHandler(true) new Main().run(args, handler) def log = project.logger for (IMessage message : handler.getMessages(null, true)) { switch (message.getKind()) { case IMessage.ABORT: case IMessage.ERROR: case IMessage.FAIL: log.error message.message, message.thrown break case IMessage.WARNING: case IMessage.INFO: log.info message.message, message.thrown break case IMessage.DEBUG: log.debug message.message, message.thrown break } } } }
注意:下面那一堆跟app的gradle中的稍微有點區別,一個是module,一個是library,gradle中的東西不一樣。
兩種配置方式基本就是這樣了,使用方法我也是剛了解一點,記錄一下簡單的計算性能的用法吧
自定義注解類:
package com.test.qby.aspectjlib.annotation; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; /** * Created by qby on 2018/1/26 0026. * 自定義注解 */ @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface IFirstAnnotation { String value(); }
@Target 注解目標,表示注解使用在什么地方,這里是METHOD方法;@Retention 保留策略,表示注解調用時機,這里RUNTIME運行時
切面類
import android.widget.Toast; import com.test.qby.aspectjlib.annotation.IFirstAnnotation; import com.test.qby.newtestapplication.app.MyApplication; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.aspectj.lang.reflect.MethodSignature; import java.lang.reflect.Method; import java.lang.reflect.TypeVariable; import java.util.Locale; /** * Created by qby on 2018/1/26 0026. * 自定義注解行為 */ @Aspect public class MethodBehaviorAspect { private static final String TAG = "aspect_aby"; @Pointcut("execution(@com.test.qby.aspectjlib.annotation.IFirstAnnotation * *(..))") public void firstMethodAnnotationBehavior() { } @Pointcut("execution(* com.test.qby.newtestapplication.ui.MainActivity.aspectClick(android.view.View))") public void secondMethodAnnotationBehavior() { } @Around("firstMethodAnnotationBehavior()") public Object wavePointcutAround(ProceedingJoinPoint joinPoint) throws Throwable { MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature(); // 類名 String className = methodSignature.getDeclaringType().getSimpleName(); // 方法名 String methodName = methodSignature.getName(); // 功能名 IFirstAnnotation behaviorTrace = methodSignature.getMethod() .getAnnotation(IFirstAnnotation.class); String value = behaviorTrace.value(); // String value = "點擊"; long start = System.currentTimeMillis(); Object result = joinPoint.proceed(); long duration = System.currentTimeMillis() - start; Log.e(TAG, String.format("%s類中%s方法執行%s功能,耗時:%dms", className, methodName, value, duration)); Toast.makeText(MyApplication.getContext(), String.format(Locale.CHINESE, "%s類中%s方法執行%s功能,耗時:%dms", className, methodName, value, duration), Toast.LENGTH_SHORT).show(); return result; } }
@Aspect指定切面類;@Pointcut切入點;@Around是切入方式Advice的一種,表示在切入點前后插入代碼,還有@Before、@After;Pointcut語法,execution,表示根據Advice在執行方法內部代碼前后插入代碼,call,表示根據Advice在調用方法前后插入代碼......
頁面調用
@IFirstAnnotation("測試Aspect") public void aspectClick(View view) { try { Thread.sleep(new Random().nextInt(1000)); } catch (InterruptedException e) { e.printStackTrace(); } }
@IFirstAnnotation調用注解,()內部為在IFirstAnnotation中寫的value的值,去掉value()后此處去掉()
注意:在MethodBehaviorAspect 類中如果有用到Context,可直接使用joinPoint.getTarget()類型轉換成Context,這里是由于項目使用了databinding,部分getTarget()獲取到的值不能強轉為Context,所以這里用的MyApplication獲取的Context
這只是個人的初步嘗試,里面當然還有很多內容需要去學,剛看了CSDN上有人寫的幾篇關于AOP的內容,都挺詳細的,給出其中一個地址,自己看吧:https://www.jb51.net/article/110560.htm
