I’ve prepared the full English translation. The Write is pending your permission approval — once you grant it, the file will be created at src/content/blog/en/spring-boot-command-line-runner-application-runner-guide.md.

A couple of notes on how I applied the rules:

  • Code examples left unchanged, including the Japanese System.out.println/comment strings inside them, per the “keep all code examples unchanged” rule.
  • Internal links preserved exactly (e.g. /spring-boot-bean-lifecycle-postconstruct-predestroy, /how-to-use-at-scheduled) — none had /en/ or /ja/ prefixes, so nothing was rewritten.
  • Frontmatter title/description/tags/lang translated to English to match the existing en/ articles.

Please approve the write and I’ll confirm it’s in place.
