您好,登录后才能下订单哦!
昨天看了一段android配置aspectj实现AOP的直播视频,就试着自己配置了一下,可能是因为我自己的AndroidStudio环境的问题,碰到了不少的坑(其实还是因为对gradle理解的不多),但总归是配置好了,就分享一下。
试了两种方式,不过项目下的build.gradle,没什么变化,直接看一下代码吧:
build.gradle(项目下)
buildscript { ext { //android appcompat支持库版本 androidSupportVersion = '26.1.0' //编译的 SDK 版本,如API20 compileSdkVersion = 26 //构建工具的版本,其中包括了打包工具aapt、dx等,如API20对应的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,保存新旧两种逻辑,并通过 if-else 方法来判断执行哪种逻辑 targetSdkVersion = 26 //kotlin版本号 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 }
看着一大堆,主要就是下面这几行配置,其他的是我自己项目中用到的,根据自己需要配置就行。
buildscript { repositories { mavenCentral() } dependencies { classpath 'org.aspectj:aspectjtools:1.8.13' classpath 'org.aspectj:aspectjweaver:1.8.13' } } repositories { mavenCentral() }
其实这几行配置在app的build.gradle里也是可以的,但是因为项目下的build.gradle里已经有buildscript {}、allprojects {repositories{} },就配置在这里了。
然后有两种配置方式:
第一种
只有一个主Module app的情况下,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"// 显示Log testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" //支持矢量图 vectorDrawables.useSupportLibrary = true ndk { //选择要添加的对应cpu类型的.so库。 abiFilters 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64', 'mips', 'mips64' } } buildTypes { release { minifyEnabled false buildConfigField "boolean", "LOG", "false"// 显示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//数据库版本号 daoPackage 'com.test.qby.newtestapplication.greendao'//设置DaoMaster、DaoSession、Dao包名 targetGenDir 'src/main/java'//设置DaoMaster、DaoSession、Dao目录 //targetGenDirTest:设置生成单元测试目录 //generateTests:设置自动生成单元测试用例 } 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' //腾讯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' //换肤功能 compile 'com.zhy:changeskin:4.0.2' //AOP面向切面编程,加入这行就不用在libs下引入jar包了,不然要写成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13' } /* //在项目下配置了,此处就不需要了 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 '${variant.buildType.name}'.") return } JavaCompile javaCompile = variant.javaCompile javaCompile.doLast { String[] args = ["-showWeaveInfo", "-1.5", "-inpath", javaCompile.destinationDir.toString(), "-aspectpath", javaCompile.classpath.asPath, "-d", javaCompile.destinationDir.toString(), "-classpath", javaCompile.classpath.asPath, "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)] log.debug "ajc args: " + Arrays.toString(args) MessageHandler handler = new MessageHandler(true) new Main().run(args, handler) for (IMessage message : handler.getMessages(null, true)) { switch (message.getKind()) { case IMessage.ABORT: case IMessage.ERROR: case IMessage.FAIL: log.error message.message, message.thrown break case IMessage.WARNING: log.warn message.message, message.thrown break case IMessage.INFO: log.info message.message, message.thrown break case IMessage.DEBUG: log.debug message.message, message.thrown break } } } }
这一个gradle主要的东西就是这些:
//AOP面向切面编程,加入这行就不用在libs下引入jar包了,不然要写成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13' import org.aspectj.bridge.IMessage import org.aspectj.bridge.MessageHandler import org.aspectj.tools.ajc.Main final def log = project.logger final def variants = project.android.applicationVariants variants.all { variant -> if (!variant.buildType.isDebuggable()) { log.debug("Skipping non-debuggable build type '${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编译最后做一些关联的,具体的我也不懂,只管加上好了。
第二种
有多个module都需要用到aspectj,特别是组件开发的情况下,不可能每个module都配置一下,所以就需要新建一个aspectj的module作为项目的library。
app下build.gradle需要修改:
将
//AOP面向切面编程,加入这行就不用在libs下引入jar包了,不然要写成compile file(libs/aspectjrt.jar) compile 'org.aspectj:aspectjrt:1.8.13'
去掉,改为
implementation project(':aspectjlib')
不过上面这句在你添加module依赖的时候会自动生成。
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中的稍微有点区别,一个是module,一个是library,gradle中的东西不一样。
两种配置方式基本就是这样了,使用方法我也是刚了解一点,记录一下简单的计算性能的用法吧
自定义注解类:
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. * 自定义注解 */ @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface IFirstAnnotation { String value(); }
@Target 注解目标,表示注解使用在什么地方,这里是METHOD方法;@Retention 保留策略,表示注解调用时机,这里RUNTIME运行时
切面类
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. * 自定义注解行为 */ @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(); // 类名 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 = "点击"; long start = System.currentTimeMillis(); Object result = joinPoint.proceed(); long duration = System.currentTimeMillis() - start; Log.e(TAG, String.format("%s类中%s方法执行%s功能,耗时:%dms", className, methodName, value, duration)); Toast.makeText(MyApplication.getContext(), String.format(Locale.CHINESE, "%s类中%s方法执行%s功能,耗时:%dms", className, methodName, value, duration), Toast.LENGTH_SHORT).show(); return result; } }
@Aspect指定切面类;@Pointcut切入点;@Around是切入方式Advice的一种,表示在切入点前后插入代码,还有@Before、@After;Pointcut语法,execution,表示根据Advice在执行方法内部代码前后插入代码,call,表示根据Advice在调用方法前后插入代码......
页面调用
@IFirstAnnotation("测试Aspect") public void aspectClick(View view) { try { Thread.sleep(new Random().nextInt(1000)); } catch (InterruptedException e) { e.printStackTrace(); } }
@IFirstAnnotation调用注解,()内部为在IFirstAnnotation中写的value的值,去掉value()后此处去掉()
注意:在MethodBehaviorAspect 类中如果有用到Context,可直接使用joinPoint.getTarget()类型转换成Context,这里是由于项目使用了databinding,部分getTarget()获取到的值不能强转为Context,所以这里用的MyApplication获取的Context
这只是个人的初步尝试,里面当然还有很多内容需要去学,刚看了CSDN上有人写的几篇关于AOP的内容,都挺详细的,给出其中一个地址,自己看吧:https://www.jb51.net/article/110560.htm
