para uma visão geral da arquitetura do Endpoints Frameworks.
Bibliotecas e ferramentas
O Cloud Endpoints Frameworks para o ambiente padrão do App Engine fornece as bibliotecas e ferramentas a seguir:
O Endpoints Frameworks está disponível no
Maven Central Repository (em inglês)
no grupo com.google.endpoints. O arquivo .jar de base necessário está no artefato endpoints-framework. Consulte o
Javadoc da API
para mais detalhes.
A ferramenta de linha de comando endpoints (para Linux) ou endpoints.cmd (para Windows) que pode ser
usada para gerar pacotes de biblioteca de cliente e
documentos Discovery,
que permitem que apps Android e outros tipos de aplicativos clientes acessem
sua API.
Crie o aplicativo cliente usando a biblioteca de cliente ao fazer chamadas para a API.
Primeiros passos
Para começar, siga o
Tutorial
para configurar, implantar e enviar solicitações a uma API de amostra. Em seguida, volte para esta
seção e encontre as informações necessárias para configurar, implantar e testar sua própria
API.
Como migrar do Endpoints 1.0
Se você já desenvolveu um back-end de API usando a versão anterior do Endpoints, siga o
Guia de migração
para migrar o app para o Endpoints 2.0.

See\n[About Endpoints Frameworks](/endpoints/docs/frameworks/about-cloud-endpoints-frameworks)\nfor an architectural overview of Endpoints Frameworks.\n\nLibraries and tools\n-------------------\n\nCloud Endpoints Frameworks for the App Engine standard environment\nprovides the following libraries and tools:\n\n\n- The Endpoints Frameworks is available in the [Maven Central Repository](http://search.maven.org/) in the group `com.google.endpoints`. The base required `.jar` file is in the `endpoints-framework` artifact. See [API Javadoc](/endpoints/docs/frameworks/java/javadoc) for details.\n- The [`endpoints`](/endpoints/docs/frameworks/java/endpoints_tool) command-line tool (for Linux), or `endpoints.cmd` (for Windows) that you can use to generate client library bundles and [Discovery documents](https://developers.google.com/discovery/v1/reference/apis), which allow Android apps and other types of client applications to access your API.\n- The [Endpoints Frameworks Maven plugin](/endpoints/docs/frameworks/java/maven-endpoints-frameworks-plugin) and the [Endpoints Frameworks Gradle plugin](/endpoints/docs/frameworks/java/gradle-endpoints-frameworks-plugin), which you use to generate the following:\n - Client library bundles and Discovery documents.\n - [OpenAPI configuration files](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md), which you use if you want [API management](/endpoints/docs/frameworks/java/adding-api-management) functionality such as monitoring, logging, and API key validation.\n\n| **Note:** Because the API backend is an App Engine application, developers can use services and features available in the App Engine standard environment, such as [Datastore](/appengine/docs/java/datastore) , [Cloud Storage](https://cloud.google.com/storage/docs/overview) , [Mail](/appengine/docs/java/mail) , [Url fetch](/appengine/docs/java/urlfetch) , [Task queues](/appengine/docs/java/taskqueue) , and so forth. And finally, by using App Engine for the backend, developers are freed from system admin work, load balancing, scaling, and server maintenance.\n\nRequirements\n------------\n\nTo use Endpoints Frameworks, follow the process shown in the\n[Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java).\n\nYou need to know how to develop the client of your choice, such as JavaScript\nweb clients, or mobile clients, such as Android.\n| **Note:** You cannot call a Cloud Endpoints API directly from a [push task queue](/appengine/docs/standard/java/taskqueue#push_queues) or a [cron job](/appengine/docs/standard/java/config/cron#Java_calling_google_cloud_endpoints).\n\nDevelopment process\n-------------------\n\nThe general workflow for developing an application using\nEndpoints Frameworks is:\n\n1. Create your API project, and then write your API code.\n2. [Annotate](/endpoints/docs/frameworks/java/annotate-code) your API, so classes and client libraries are generated from it.\n3. Generate the OpenAPI configuration file and deploy it as described in the [Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java).\n4. Optionally, [test your API locally](/endpoints/docs/frameworks/java/test-deploy#running_and_testing_api_backends_locally).\n5. [Deploy the API](/endpoints/docs/frameworks/java/test-deploy).\n6. [Generate the client library](/endpoints/docs/frameworks/java/gen_clients).\n7. Write your client application by using the client library when making calls to the API.\n\nGetting started\n---------------\n\nTo get started, follow the\n\n\n[Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java)\n\nto configure, deploy, and send requests to a sample API. Then come back to this\nsection for the information you need to configure, deploy, and test your own\nAPI.\n\nMigrating from Endpoints version 1.0\n------------------------------------\n\nIf you've already developed an API backend using the previous version of\nEndpoints, follow the\n\n[Migration guide](/endpoints/docs/frameworks/java/migrating)\n\nto move your app to Endpoints version 2.0."]]
