1. 在工程根目录的build.gradle中添加依赖(加粗部分)
在buildscript的dependencies中添加如下代码
classpath 'org.aspectj:aspectjtools:1.9.2'
classpath 'org.aspectj:aspectjweaver:1.9.2'
2. 在library/module中添加依赖
implementation 'org.aspectj:aspectjrt:1.9.2'
3. 添加gradle任务
如果你只在你的Application module使用aop,在这个module中的gradle添加如下代码,直接添加在最后就行。
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 '${variant.buildType.name}'.")
return;
}
JavaCompile javaCompile = variant.javaCompile
javaCompile.doLast {
String[] args = ["-showWeaveInfo",
"-1.8",
"-inpath", javaCompile.destinationDir.toString(),
"-aspectpath", javaCompile.classpath.asPath,
"-d", javaCompile.destinationDir.toString(),
"-classpath", javaCompile.classpath.asPath,
"-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]
log.debug "ajc args: " + Arrays.toString(args)
MessageHandler handler = new MessageHandler(true);
new Main().run(args, handler);
for (IMessage message : handler.getMessages(null, true)) {
switch (message.getKind()) {
case IMessage.ABORT:
case IMessage.ERROR:
case IMessage.FAIL:
log.error message.message, message.thrown
break;
case IMessage.WARNING:
log.warn message.message, message.thrown
break;
case IMessage.INFO:
log.info message.message, message.thrown
break;
case IMessage.DEBUG:
log.debug message.message, message.thrown
break;
}
}
}
}
那么问题来了,如果你的library module中也使用到了aop,这时没有添加依赖的话,使用到library中被@Aspect标注的类的时候,就会出现java.lang.NoSuchMethodError: No static method aspectOf()这个错误。
在library module 中添加依赖的方法如下,也是和之前一样,添加在build.gradle的最后就好了.
import org.aspectj.bridge.IMessage
import org.aspectj.bridge.MessageHandler
import org.aspectj.tools.ajc.Main
final def log = project.logger
android.libraryVariants.all{ variant ->
if (!variant.buildType.isDebuggable()) {
log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.")
return
}
JavaCompile javaCompile = variant.javaCompiler
javaCompile.doLast {
String[] args = ["-showWeaveInfo",
"-1.8",
"-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
}
}
}
}
4. gradle_plugin_android_aspectjx
// AOP 配置
aspectjx {
// 排除一些第三方库的包名(Gson、 LeakCanary 和 AOP 有冲突)
// 否则就会起冲突:ClassNotFoundException: Didn't find class on path: DexPathList
exclude 'androidx', 'com.google', 'com.squareup', 'com.alipay', 'com.taobao',
'com.baidu','map','vi', 'org.apache', 'com.chad'
}
