ArouterGradlePlugin

简介

本插件可实现AGP7.4+和AGP8下ARouter框架自动化插桩，使用方法和com.alibaba:arouter-register 完全一致，无缝替换；

Koltin

Using the plugins DSL:

plugins {
    id("io.github.JailedBird.ARouterPlugin") version "1.0.1"
}

Using legacy plugin application:

buildscript {
    repositories {
        gradlePluginPortal()
    }
    dependencies {
        classpath("io.github.JailedBird:arouter-gradle-plugin:1.0.1")
    }
}

apply(plugin = "io.github.JailedBird.ARouterPlugin")

}

buildscript {
  repositories {

    classpath "io.github.JailedBird:arouter-gradle-plugin:1.0.1"
  }
}

apply plugin: "io.github.JailedBird.ARouterPlugin"

插桩代码

遍历注解处理器生成的路由信息，然后在loadRouterMap函数中插桩

override fun visitInsn(opcode: Int) {
    // generate code before return
    if (opcode in Opcodes.IRETURN..Opcodes.RETURN) {
        targetList?.forEach { scanSetting ->
            scanSetting.classList.forEach { name ->
                val className = name.replace("/", ".")
                mv.visitLdcInsn(className)// 类名
                
                mv.visitMethodInsn(
                    Opcodes.INVOKESTATIC,
                    ScanSetting.GENERATE_TO_CLASS_NAME,
                    ScanSetting.REGISTER_METHOD_NAME,
                    "(Ljava/lang/String;)V",
                    false
                )
            }
        }
    }
    super.visitInsn(opcode)
}

插桩后字节码如下：

.method public static loadRouterMap()V
    .registers 1
    
    .line 63
    const/4 v0, 0x0
    sput-boolean v0, Lcom/alibaba/android/arouter/core/LogisticsCenter;->registerByPlugin:Z

    .line 68
    const-string v0, "com.alibaba.android.arouter.routes.ARouter$$Root$$app"
    invoke-static {v0}, Lcom/alibaba/android/arouter/core/LogisticsCenter;->register(Ljava/lang/String;)V
    
    const-string v0, "com.alibaba.android.arouter.routes.ARouter$$Root$$arouterapi"
    invoke-static {v0}, Lcom/alibaba/android/arouter/core/LogisticsCenter;->register(Ljava/lang/String;)V
    
    const-string v0, "com.alibaba.android.arouter.routes.ARouter$$Providers$$app"
    invoke-static {v0}, Lcom/alibaba/android/arouter/core/LogisticsCenter;->register(Ljava/lang/String;)V
    
    const-string v0, "com.alibaba.android.arouter.routes.ARouter$$Providers$$arouterapi"
    invoke-static {v0}, Lcom/alibaba/android/arouter/core/LogisticsCenter;->register(Ljava/lang/String;)V

    return-void
.end method
