Spring makes programming Java quicker, easier, and safer for everybody. Spring’s focus on speed, simplicity, and productivity has made it the [world's most popular](https://snyk.io/blog/jvm-ecosystem-report-2018-platform-application/) Java framework.
## Spring is everywhere
Spring’s flexible libraries are trusted by developers all over the world. Spring delivers delightful experiences to millions of end-users every day—whether that’s [streaming TV](https://medium.com/netflix-techblog/netflix-oss-and-spring-boot-coming-full-circle-4855947713a0), [online shopping](https://tech.target.com/2018/12/18/spring-feign.html), or countless other innovative solutions. Spring also has contributions from all the big names in tech, including Alibaba, Amazon, Google, Microsoft, and more.
## Spring is flexible
Spring’s flexible and comprehensive set of extensions and third-party libraries let developers build almost any application imaginable. At its core, Spring Framework’s [Inversion of Control (IoC)](https://en.wikipedia.org/wiki/Inversion_of_control) and [Dependency Injection (DI)](https://en.wikipedia.org/wiki/Dependency_injection) features provide the foundation for a wide-ranging set of features and functionality. Whether you’re building secure, reactive, cloud-based microservices for the web, or complex streaming data flows for the enterprise, Spring has the tools to help.
## Spring is productive
[Spring Boot](https://spring.io/guides/gs/spring-boot/) transforms how you approach Java programming tasks, radically streamlining your experience. Spring Boot combines necessities such as an application context and an auto-configured, embedded web server to make [microservice](https://spring.io/microservices) development a cinch. To go even faster, you can combine Spring Boot with Spring Cloud’s rich set of supporting libraries, servers, patterns, and templates, to safely deploy entire microservices-based architectures into the [cloud](https://spring.io/cloud), in record time.
## Spring is fast
Our engineers care deeply about performance. With Spring, you’ll notice fast startup, fast shutdown, and optimized execution, by default. Increasingly, Spring projects also support the [reactive](https://spring.io/reactive)(nonblocking) programming model for even greater efficiency. Developer productivity is Spring’s superpower. Spring Boot helps developers build applications with ease and with far less toil than other competing paradigms. Embedded web servers, auto-configuration, and “fat jars” help you get started quickly, and innovations like [LiveReload in Spring DevTools](https://docs.spring.io/spring-boot/docs/current/reference/html/using-spring-boot.html#using-boot-devtools-livereload) mean developers can iterate faster than ever before. You can even start a new Spring project in seconds, with the Spring Initializr at [start.spring.io](https://start.spring.io/).
## Spring is secure
Spring has a proven track record of dealing with security issues quickly and responsibly. The Spring committers work with security professionals to patch and test any reported vulnerabilities. Third-party dependencies are also monitored closely, and regular updates are issued to help keep your data and applications as safe as possible. In addition, [Spring Security](https://spring.io/projects/spring-security) makes it easier for you to integrate with industry-standard security schemes and deliver trustworthy solutions that are secure by default.
## Spring is supportive
The [Spring community](https://spring.io/community) is enormous, global, diverse, and spans folks of all ages and capabilities, from complete beginners to seasoned pros. No matter where you are on your journey, you can find the support and resources you need to get you to the next level: [quickstarts](https://spring.io/quickstart), [guides & tutorials](https://spring.io/guides), [videos](https://www.youtube.com/channel/UC7yfnfvEUlXUIfm8rGLwZdA), [meetups](https://spring.io/events), [support](https://spring.io/support), or even formal [training and certification](https://spring.io/training).
# What can Spring do?
## Microservices
Quickly deliver production‑grade features with independently evolvable microservices.
## Reactive
Spring's asynchronous, nonblocking architecture means you can get more from your computing resources.
## Cloud
Your code, any cloud—we’ve got you covered. Connect and scale your services, whatever your platform.
## Web apps
Frameworks for fast, secure, and responsive web applications connected to any data store.
## Serverless
The ultimate flexibility. Scale up on demand and scale to zero when there’s no demand.
## Event Driven
Integrate with your enterprise. React to business events. Act on your streaming data in realtime.
## Batch
Automated tasks. Offline processing of data at a time to suit you.
Spring 让每个人都可以更快、更轻松、更安全地编写 Java。Spring 对速度、简单性和生产力的关注使其成为[世界上最受欢迎的](https://snyk.io/blog/jvm-ecosystem-report-2018-platform-application/)Java 框架。
## 春天无处不在
Spring 的灵活库受到全世界开发人员的信赖。Spring 每天为数百万最终用户提供令人愉悦的体验——无论是[流媒体电视](https://medium.com/netflix-techblog/netflix-oss-and-spring-boot-coming-full-circle-4855947713a0),[网上购物](https://tech.target.com/2018/12/18/spring-feign.html)，或无数其他创新解决方案。Spring 也有来自所有科技巨头的贡献，包括阿里巴巴、亚马逊、谷歌、微软等。
## 弹簧很灵活
Spring 灵活而全面的扩展集和第三方库让开发人员可以构建几乎任何可以想象的应用程序。Spring 框架的核心是[控制反转 (IoC)](https://en.wikipedia.org/wiki/Inversion_of_control)和[依赖注入 (DI)](https://en.wikipedia.org/wiki/Dependency_injection)特性为广泛的特性和功能集提供了基础。无论您是为 Web 构建安全、反应式、基于云的微服务，还是为企业构建复杂的流数据流，Spring 都有可以提供帮助的工具。
## 春天是生产力
[弹簧靴](https://spring.io/guides/gs/spring-boot/)改变您处理 Java 编程任务的方式，从根本上简化您的体验。Spring Boot 结合了应用程序上下文和自动配置的嵌入式 Web 服务器等必需品，[微服务](https://spring.io/microservices)发展小菜一碟。为了更快，您可以将 Spring Boot 与 Spring Cloud 丰富的支持库、服务器、模式和模板集相结合，以安全地将整个基于微服务的架构部署到[云](https://spring.io/cloud)，在创纪录的时间内。
## 春天来得很快
我们的工程师非常关心性能。使用 Spring，您会注意到默认情况下快速启动、快速关闭和优化执行。Spring 项目也越来越多地支持[反应式](https://spring.io/reactive)（非阻塞）编程模型，效率更高。开发人员的生产力是 Spring 的超能力。Spring Boot 可帮助开发人员轻松构建应用程序，并且比其他竞争范式更省力。嵌入式 Web 服务器、自动配置和“fat jars”可帮助您快速入门，创新如[Spring DevTools 中的 LiveReload](https://docs.spring.io/spring-boot/docs/current/reference/html/using-spring-boot.html#using-boot-devtools-livereload)意味着开发人员可以比以往更快地迭代。您甚至可以在几秒钟内启动一个新的 Spring 项目，Spring Initializr 位于[启动.spring.io](https://start.spring.io/).
## 春天是安全的
Spring 在快速、负责任地处理安全问题方面有着良好的记录。Spring 提交者与安全专家合作，修补和测试任何报告的漏洞。第三方依赖项也受到密切监控，并定期发布更新以帮助确保您的数据和应用程序尽可能安全。此外，[春季安全](https://spring.io/projects/spring-security)让您更轻松地与行业标准的安全方案集成，并提供默认安全的值得信赖的解决方案。
