Spring Boot CLI 提供了一种有趣的、不同寻常的 Spring 应用程序开发方式。后续章节将详细解释 Spring Boot CLI 提供的功能。我们先来看看如何安装Spring Boot CLI！
安装Spring Boot CLI最直接的方法大约是下载、 解压， 随后将它的bin目录添加到系统路径里。你可以从以下两个地址下载分发包：
下载完成之后，把它解压到文件系统的任意目录里。Spring Boot CLI 目录结构如下图：
进入 bin 目录，其中包含了一个 spring.bat 脚本（用于Windows环境）和一个spring脚本（用于 Unix/Linux 环境）。如下图：
把这个bin目录添加到系统路径里，然后就能使用 Spring Boot CLI了。如下：
C:\Users\Administrator> spring --version Spring CLI v2.3.1.RELEASE
在使用 Spring Boot CLI 之前，我们可以使用 “spring --help” 命令查看 帮助信息。如下：
C:\Users\Administrator\Desktop>spring --help usage: spring [--help] [--version] <command> [<args>] Available commands are: run [options] <files> [--] [args] Run a spring groovy script grab Download a spring groovy script's dependencies to ./repository jar [options] <jar-name> <files> Create a self-contained executable jar file from a Spring Groovy script war [options] <war-name> <files> Create a self-contained executable war file from a Spring Groovy script install [options] <coordinates> Install dependencies to the lib/ext directory uninstall [options] <coordinates> Uninstall dependencies from the lib/ext directory init [options] [location] Initialize a new project using Spring Initializr (start.spring.io) encodepassword [options] <password to encode> Encode a password for use with Spring Security shell Start a nested shell Common options: --debug Verbose mode Print additional status information for the command you are running See 'spring help <command>' for more information on a specific command.
根据上面帮助信息，我们可以使用 init（Initialize a new project using Spring Initializr (start.spring.io)） 命令创建项目。
使用 “spring help init” 查看 init 命令的帮助信息。如下：
C:\Users\Administrator\Desktop>spring help init spring init - Initialize a new project using Spring Initializr (start.spring.io) usage: spring init [options] [location] Option Description ------ ----------- -a, --artifactId <String> Project coordinates; infer archive name (for example 'test') -b, --boot-version <String> Spring Boot version (for example '1.2.0.RELEASE') --build <String> Build system to use (for example 'maven' or 'gradle') (default: maven) -d, --dependencies <String> Comma-separated list of dependency identifiers to include in the generated project --description <String> Project description -f, --force Force overwrite of existing files --format <String> Format of the generated content (for example 'build' for a build file, 'project' for a project archive) (default: project) -g, --groupId <String> Project coordinates (for example 'org.test') -j, --java-version <String> Language level (for example '1.8') -l, --language <String> Programming language (for example 'java') --list List the capabilities of the service. Use it to discover the dependencies and the types that are available -n, --name <String> Project name; infer application name -p, --packaging <String> Project packaging (for example 'jar') --package-name <String> Package name -t, --type <String> Project type. Not normally needed if you use -- build and/or --format. Check the capabilities of the service (--list) for more details --target <String> URL of the service to use (default: https://start. spring.io) -v, --version <String> Project version (for example '0.0.1-SNAPSHOT') -x, --extract Extract the project archive. Inferred if a location is specified without an extension examples: To list all the capabilities of the service: $ spring init --list To creates a default project: $ spring init To create a web my-app.zip: $ spring init -d=web my-app.zip To create a web/data-jpa gradle project unpacked: $ spring init -d=web,jpa --build=gradle my-dir
根据上面的帮助创建一个简单的项目。实例：
spring init --build=maven --java-version=1.8 --dependencies=web --packaging=jar --boot-version=1.5.7.RELEASE --groupId=com.hxstrive.demo --artifactId=demo
