这是2个选项：
（1）从命令行调用Rest API
您可以创建一个Spring
@RestController，然后从命令行调用它？
curl -X POST -i -H "Content-type: application/json" -c cookies.txt -X POST http://hostname:8080/service -d ' { "field":"value", "field2":"value2" } '您可以轻松地将其嵌入一个不错的shell脚本中。
（2）使用spring-boot-remote-shell（已弃用）
尽管它主要用于监视/管理目的，但是您可以使用spring-boot-remote-shell。
依存关系
您需要以下依赖项才能启用远程外壳程序：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-remote-shell</artifactId></dependency><dependency> <groupId>org.crsh</groupId> <artifactId>crsh.shell.telnet</artifactId> <version>1.3.0-beta2</version></dependency>
Groovy脚本 ：
在中添加以下脚本
src/main/resources/custom.groovy：
package commandsimport org.crsh.cli.Commandimport org.crsh.cli.Usageimport org.crsh.command.InvocationContextclass custom { @Usage("Custom command") @Command def main(InvocationContext context) { return "Hello" }}要从该groovy脚本中获取Springbean：
BeanFactory beanFactory = (BeanFactory) context.getAttributes().get("spring.beanfactory");MyController myController = beanFactory.getBean(MyController.class);启动您的SpringBootApp
在类路径上使用spring-boot-remote-shell时，Spring Boot应用程序在端口5000上侦听（默认情况下）。您现在可以执行以下操作：
$ telnet localhost 5000Trying ::1...Connected to localhost.Escape character is '^]'. . ____ _ __ _ _ /\ / ___'_ __ _ _(_)_ __ __ _ ( ( )___ | '_ | '_| | '_ / _` | \/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |___, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.3.5.RELEASE)
帮帮我
您可以键入
help以查看可用命令的列表：
NAME DEscriptION autoconfig Display auto configuration report from ApplicationContext beans Display beans in ApplicationContext cron manages the cron plugin custom Custom command dashboard egrep search file(s) for lines that match a pattern endpoint Invoke actuator endpoints env display the term env filter A filter for a stream of map help provides basic help java various java language commands jmx Java Management Extensions jul java.util.logging commands jvm JVM informations less opposite of more log logging commands mail interact with emails man format and display the on-line manual pages metrics Display metrics provided by Spring Boot shell shell related command sleep sleep for some time sort Sort a map system vm system properties commandsthread JVM thread commands
调用我们的自定义命令
我们的自定义命令已列出（自上而下的第四个），您可以调用它：
> customHello
因此，从本质上讲，您的crontab将
telnet 5000执行
custom
（3）如何使用参数和选项（在评论中回答问题）
争论
要使用参数，可以看一下文档：
class date { @Usage("show the current time") @Command Object main( @Usage("the time format") @Option(names=["f","format"]) String format) { if (format == null) format = "EEE MMM d HH:mm:ss z yyyy"; def date = new Date(); return date.format(format); }}% date -h% usage: date [-h | --help] [-f | --format]% [-h | --help] command usage% [-f | --format] the time format% date -f yyyyMMdd子命令（或选项）
仍然从他们的文档中：
@Usage("JDBC connection")class jdbc { @Usage("connect to database with a JDBC connection string") @Command public String connect( @Usage("The username") @Option(names=["u","username"]) String user, @Usage("The password") @Option(names=["p","password"]) String password, @Usage("The extra properties") @Option(names=["properties"]) Properties properties, @Usage("The connection string") @Argument String connectionString) { ... } @Usage("close the current connection") @Command public String close() { ... }}% jdbc connect jdbc:derby:memory:EmbeddedDB;create=true最后一条命令执行：
- 命令
jdbc
- 与子命令
connect
- 和论点
jdbc:derby:memory:EmbeddedDB;create=true
一个完整的例子
以下内容包括：
- 构造函数；
- 带参数的命令；
- spring管理的豆；
- 带有参数的子命令。
编码：
