执行CommandLineRunner - Spring批处理失败
执行CommandLineRunner - Spring批处理失败

嗨，我是Spring batch的新手，我得到了以下我无法解决的异常：
java.lang.IllegalStateException: Failed to execute CommandLineRunner

... 10 common frames omitted我的代码如下：
@SpringBootApplication
public class BatchDemo {
public static void main(String args[])
{
SpringApplication.run(BatchDemo.class);
}
}我可以通过添加exclude = BatchAutoConfiguration.class来解决这个问题。但我想找出真正的原因并解决它。
我没有传递任何命令行参数，并且这种异常并不总是发生。

对于希望实际执行批处理作业的任何人，如果遇到此错误，请尝试检查Spring批处理元数据表中的记录是否存在任何不一致。
为了获得下一个JobParameters，Spring Batch会搜索与您的作业具有相同JOB_NAME的最新BATCH_JOB_INSTANCE，然后在数据库(通过JOB_INSTANCE_ID链接)中查找匹配的BATCH_JOB_EXECUTION记录。
我们有一个内部任务在运行，该任务从BATCH_JOB_EXECUTION中删除了记录，但由于错误，没有从BATCH_JOB_INSTANCE中删除匹配的记录。
在一个环境中，我们已经有3个多月没有执行任何作业了，所以我们没有BATCH_JOB_EXECUTION记录，但有大量的BATCH_JOB_INSTANCE记录。我们反复使用这个问题中列出的堆栈跟踪，跨越多个不同的Spring批处理应用程序，但在任何地方都找不到在线解决方案。
我们通过以下方式解决了问题
- 在
BATCH_JOB_INSTANCE中没有匹配记录的情况下运行SQL从BATCH_JOB_EXECUTION中删除-这在短期内解除了作业的阻塞；并且， - 使用spring-batch-toolkit将我们的清除任务替换为作业；它提供了正确删除记录的RemoveSpringBatchHistoryTasklet。
