推荐答案

基本上你可以遵循 2 种方法:

Basically you can follow 2 approaches for that:

1. 确保每个实例管理自己的数据(不与任何其他实例共享).
2. 确保每次只有一个实例可以访问信息.

第一点取决于你自己的业务逻辑，第二点有一些工具可以帮助你，与 Spring 轻松集成:

The first point depends of your own business logic, for the second one there are some tools can help you, with an easy integration with Spring:

Quartz

Shedlock(比 Quartz 简单但功能较少)

Shedlock (easier than Quartz but with less functionality)
