Introduction

This section is intended to demonstrate how to use Jarslink 2.0 to dynamically control the life cycle of the Biz package and to complete its installation, uninstallation, and query.

Demo

With reference to How to reform common Spring Boot applications, the reformed spring-boot-transform-sample project has integrated the Jarslink 2.0 component. By executing the Ark package that the application packaged and generated, you can dynamically install or uninstall the application during its running.

  • java -jar starts the spring-boot-transform-sample application Ark package.
  • telnet localhost 1234 enters the Jarslink 2.0 command interface, as follows:
    > telnet localhost 1234 s > Trying 127.0.0.1…
    > Connected to localhost.
    > Escape character is ‘^]’.
    > sofa-ark>
  • Execute the check -b query command, and the result is as follows: > sofa-ark>check -b
    > Biz count=1
    > bizName=‘spring-boot-transform-sample’, bizVersion=‘1.0.0’, bizState=‘activated’ > > sofa-ark>

  • With reference to How to reform a common Spring Boot application, create any SOFABoot application of non-Web type, package it into a Biz package, and execute the install -b installation command, and the result is as follows: > sofa-ark>install -b file:///Users/qilong.zql/Desktop/test-ark-biz.jar
    > Biz:‘test-biz:1.0.0’ is installing. > > sofa-ark>

  • Execute the check -b query command again, and the result is as follows: > sofa-ark>check -b
    > Biz count=2
    > bizName=‘test-biz’, bizVersion=‘1.0.0’, bizState=‘activated’
    > bizName=‘spring-boot-transform-sample’, bizVersion=‘1.0.0’, bizState=‘activated’ > > sofa-ark>

  • Execute the uninstall -b -n -v uninstallation command, and the result is as follows: > sofa-ark>uninstall -b -n test-biz -v 1.0.0
    > Uninstall biz:‘test-biz:1.0.0’ success. > > sofa-ark>

  • Execute the check -b query command again, and the result is as follows: > sofa-ark>check -b
    > Biz count=1
    > bizName=‘spring-boot-transform-sample’, bizVersion=‘1.0.0’, bizState=‘activated’ > > sofa-ark>
