Runtime Java
Ringkasan
Fungsi Cloud Run Anda berjalan di lingkungan yang terdiri dari versi sistem operasi plus paket add-on, dukungan bahasa, dan library Functions Framework yang mendukung dan memanggil fungsi Anda.
Lingkungan ini diidentifikasi berdasarkan versi bahasa, dan dikenal sebagai runtime.
Untuk informasi tentang runtime secara umum, dan untuk mempelajari versi Ubuntu yang digunakan setiap runtime Java, lihat lingkungan eksekusi fungsi Cloud Run.
Memilih runtime Anda
Fungsi Cloud Run mendukung beberapa versi Java, yang tercantum di halaman Dukungan runtime. Anda dapat memilih Java Ruby yang diinginkan untuk fungsi Anda selama deployment.
gcloud
Jika Anda menggunakan Google Cloud CLI, tentukan runtime
menggunakan parameter --runtime. Flag --entry-point menentukan
nama class yang sepenuhnya memenuhi syarat (fully qualified class name/FQN). Contoh:
Jika Anda menggunakan konsol Google Cloud , pilih runtime saat membuat dan men-deploy fungsi. Lihat
panduan memulai konsolGoogle Cloud untuk
mengetahui petunjuk mendetail.
Persiapan fungsi
Anda dapat menyiapkan fungsi langsung dari konsol Google Cloud atau menulisnya di komputer lokal, lalu menguploadnya. Guna menyiapkan mesin lokal untuk pengembangan Java, lihat Menyiapkan Lingkungan Pengembangan Java.
Library yang memanggil fungsi Anda adalah Framework Fungsi
Java.
Untuk mulai menggunakan Java di fungsi Cloud Run, lihat Panduan memulai.
Struktur kode sumber
Agar fungsi Cloud Run dapat menemukan definisi fungsi Anda, kode sumber harus mengikuti struktur tertentu. Lihat artikel Menulis fungsi Cloud Run untuk mengetahui informasi selengkapnya.
Runtime Java Anda akan otomatis menetapkan variabel lingkungan tertentu untuk digunakan fungsi Anda sesuai kebutuhan. Untuk mengetahui detailnya, lihat Menggunakan Variabel Lingkungan.

You can\nselect the preferred Ruby Java for your function during deployment. \n\n### gcloud\n\nIf you're using the Google Cloud CLI, specify the runtime\nby using the `--runtime` parameter. The `--entry-point` flag specifies the\nfully qualified class name (FQN). For example: \n\n```bash\ngcloud functions deploy NAME --no-gen2 --entry-point FQN --no-gen2 --runtime java17 --trigger-http\n```\n\nFor more deployment parameters, see [Deploy a Cloud Run function](/functions/1stgendocs/deploy#basics).\n\n### Console\n\nIf you're using the Google Cloud console, select the runtime when\nyou create and deploy your function. See the\n[Google Cloud console quickstart](/functions/1stgendocs/console-quickstart-1st-gen) for\ndetailed instructions.\n\nFunction preparation\n--------------------\n\nYou can prepare a function directly from the Google Cloud console or write it on\nyour local machine and upload it. To prepare your local machine for Java\ndevelopment, see [Setting Up a Java Development Environment](/java/docs/setup).\nThe library that invokes your function is the [Java Functions\nFramework](/functions/1stgendocs/functions-framework).\n\nTo get started with Java on Cloud Run functions, see the\n[Quickstart](/functions/1stgendocs/create-deploy-gcloud-1st-gen).\n\nSource code structure\n---------------------\n\nFor Cloud Run functions to find your function's definition, your\nsource code must follow a specific structure. See\n[Writing Cloud Run functions](/functions/1stgendocs/writing#structuring_source_code)\nfor more information.\n\nSpecifying dependencies\n-----------------------\n\nYou can specify dependencies for your function using [Maven](https://maven.apache.org/) or [Gradle](https://gradle.org/). For more information,\nsee [Specifying dependencies in\nJava](/functions/1stgendocs/writing/specifying-dependencies-java).\n\nEnvironment variables\n---------------------\n\nYour Java runtime automatically sets certain environment variables for your\nfunction to use as needed. For details, see [Using Environment\nVariables](/functions/1stgendocs/configuring/env-var).\n\nWhat's next\n-----------\n\n- [Learn how to use Java frameworks](/functions/1stgendocs/concepts/java-frameworks) that provide out-of-the-box support for writing Java Cloud Run functions.\n- [Learn how to use popular APIs and logging\n frameworks](/functions/1stgendocs/concepts/java-logging) to configure the logging behavior of Java Cloud Run functions.\n- [Learn about the other JVM languages](/functions/1stgendocs/concepts/jvm-langs) you can use to write Cloud Run functions: Kotlin, Groovy, and Scala."]]
