Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run".
We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need minimal Spring configuration.
If you’re looking for information about a specific version, or instructions about how to upgrade from an earlier release, check out the project release notes section on our wiki.
Features
-
Create stand-alone Spring applications
-
Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
-
Provide opinionated 'starter' dependencies to simplify your build configuration
-
Automatically configure Spring and 3rd party libraries whenever possible
-
Provide production-ready features such as metrics, health checks, and externalized configuration
-
Absolutely no code generation and no requirement for XML configuration
1、创建独立的Spring应用
2、内嵌web容器：直接嵌入Tomcat、Jetty 或者Undertow容器，不用打部署war文件
3、固化start依赖：提供starter依赖以简化构建配置步骤
spring boot SPI机制、条件配置、属性配置等特性，只要引入spring-boot-starter-*，就会自用引入所需要的全部依赖
4、自动化配置：条件满足自动装配Spring或第三方类库
5、健康监控：提供运维特性，例如指标信息、健康检查和外部化配置
6、无xml配置：绝无代码生成，且无需配置xml
