一 首先配置aop
需要添加一下
import org.aspectj.bridge.IMessage
import org.aspectj.bridge.MessageHandler
import org.aspectj.tools.ajc.Main
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'org.aspectj:aspectjtools:1.8.9'
classpath 'org.aspectj:aspectjweaver:1.8.9'
}
}
repositories {
mavenCentral()
}
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.errormessage.message,message.thrown
break;
case IMessage.WARNING:
log.warnmessage.message,message.thrown
break;
case IMessage.INFO:
log.info message.message,message.thrown
break;
case IMessage.DEBUG:
log.debug message.message,message.thrown
break;
}
}
}
}
implementation 'org.aspectj:aspectjrt:1.8.1' // 在dependencies配置
二 ,使用
三 aop注解
@Aspect：声明切面，标记类
@Pointcut(切点表达式)：定义切点，标记方法
@Before(切点表达式)：前置通知，切点之前执行
@Around(切点表达式)：环绕通知，切点前后执行
@After(切点表达式)：后置通知，切点之后执行
@AfterReturning(切点表达式)：返回通知，切点方法返回结果之后执行
@AfterThrowing(切点表达式)：异常通知，切点抛出异常时执行
