检查日志我们可以检测到一切都已完成。
但
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COMPLETEDbut exit_codeis NOOP。
我也检测到，使用.allowStartIfComplete(true)forstep触发器tasklet执行。但这就像一个 hack，它只能在同一作业范围内单次用于该步骤（它不适用于同一作业中的双例执行步骤）。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();
}
如果我在终端启动项目 - 它可以正常工作。
我的环境：
- OpenJDK 运行环境 Zulu11.29+3-CA (build 11.0.2+7-LTS)
- 摇篮 5.4.1
- Idea社区（刚安装最新版本）
- 操作系统 ubuntu 18.04
- 从想法启动应用程序的命令是：

问题
我猜想法的问题，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？
附言
我已经做了下一次不成功的尝试来修复它：
- 重新安装的想法；
- 从准备好的来源和春季开始重新创建项目；
- 重新启动想法使缓存无效 -
