在 Intellij Idea 中忽略了 spring 个批处理 Tasklet

查看日志我们可以发现一切都已完成。
但是
Tasklets 没有被执行。因为这个我真的很困惑。
检查数据库我检测到作业状态是 COMPLETED 但 exit_code 是 NOOP.
我还检测到，对 step 使用 .allowStartIfComplete(true) 会触发 tasklet 执行。但这就像一个 hack，它只能在同一作业范围内用于该步骤一次（它不适用于同一作业中的案例双重执行步骤）。例如：
@Bean
public Step step2() {
return stepBuilderFactory.get("step2")
.allowStartIfComplete(true)
.tasklet((contribution, chunkContext) -> {
System.out.println(">> This is step 2");
return RepeatStatus.FINISHED;
}).build();
}

问题
我猜想法有问题，因为它在终端中有效。有什么方法可以分析和检测我的案例的原因并解决它，如何解决？
P.S.
我做了下一次不成功的修复尝试：
- 重新安装想法；
- 从准备好的源重新创建项目并从 spring 开始；
- 重新启动使缓存无效的想法
-
看来不是intellij idea的问题...
我试图删除我配置的 datasource 尝试使用嵌入式数据库对默认配置进行实验。它工作正常。接下来，我使用了我的第一个 datasource 配置，但使用了不同的步骤名称。这样可行。检查数据库我检测到每个执行的步骤都有 COMPLETED 状态。
继续调查...
我的每一步在数据库中都有 COMPLETED 状态。默认情况下 spring 批处理不允许执行已完成的步骤。
要使 COMPLETED 个步骤再处理一次，我们可以：
- 用
STOPPED 或 FAILED 更新数据库中的 COMPLETED 状态 - 这真的很 hack
- 在 step builder 函数中使用
.allowStartIfComplete(true) - spring batch. 的特性

问题
我猜想法有问题，因为它在终端中有效。有什么方法可以分析和检测我的案例的原因并解决它，如何解决？
P.S.
我做了下一次不成功的修复尝试：
- 重新安装想法；
- 从准备好的源重新创建项目并从 spring 开始；
- 重新启动使缓存无效的想法 -
看来不是intellij idea的问题...
我试图删除我配置的 datasource 尝试使用嵌入式数据库对默认配置进行实验。它工作正常。接下来，我使用了我的第一个 datasource 配置，但使用了不同的步骤名称。这样可行。检查数据库我检测到每个执行的步骤都有 COMPLETED 状态。
继续调查...
我的每一步在数据库中都有 COMPLETED 状态。默认情况下 spring 批处理不允许执行已完成的步骤。
要使 COMPLETED 个步骤再处理一次，我们可以：
- 用
STOPPED或FAILED更新数据库中的COMPLETED状态 - 这真的很 hack - 在 step builder 函数中使用
.allowStartIfComplete(true)- spring batch. 的特性
