SpringBoot-2.2.5 对java jdk maven Servlet容器版本配置要求

环境要求

1、java8及以上并兼容java 13，需要Java SDK v1.8 or higher

C:\Users\mr_fan>java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

2、Maven及Gradle

Build Tool	Version
Maven	3.3+
Gradle	5.x and 6.x (4.10 is also supported but in a deprecated form)

C:\Users\mr_fan>mvn -v
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00)
Maven home: D:\developTools\apache-maven-3.6.1\bin\..
Java version: 1.8.0_191, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk1.8.0_191\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

3、Servlet 容器支持

name	Servlet Version
Tomcat 9.0	4.0
Jetty 9.4	3.1
Undertow 2.0	4.0

4、安装maven

Spring引导依赖项使用org.springframework.Boot groupId。通常，Maven POM文件继承自spring boot starter父项目，并向一个或多个“Starters”声明依赖关系。Spring Boot还提供了一个可选的Maven插件来创建可执行jar。
下面的列表显示了一个典型的pom.xml文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
