Installation (Installation) _ Spring Cloud CLISpring Boot CLI provides Spring Boot command line features for Spring Cloud. You can write Groovy scripts to run Spring Cloud component applications (e.g. @EnableEurekaServer). You can also easily do things like encryption and decryption to support Spring Cloud Config clients with secret configuration values. With the Launcher CLI you can launch services like Eureka, Zipkin, Config Server conveniently all at once from the command line (very useful at development time).中文文档(官方文档中文翻译)|Spring 教程 —

Installation

To install, make sure you have Spring Boot CLI (2.0.0 or better):spring-doc.cn

$ spring version
Spring CLI v2.2.3.RELEASE

E.g. for SDKMan usersspring-doc.cn

$ sdk install springboot 2.2.3.RELEASE
$ sdk use springboot 2.2.3.RELEASE

and install the Spring Cloud pluginspring-doc.cn

$ mvn install
$ spring install org.springframework.cloud:spring-cloud-cli:2.2.0.RELEASE

Prerequisites: to use the encryption and decryption features you need the full-strength JCE installed in your JVM (it’s not there by default). You can download the "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from Oracle, and follow instructions for installation (essentially replace the 2 policy files in the JRE lib/security directory with the ones that you downloaded).
