我们正在从Spring Batch 2.2升级到Spring Batch 4.1。我的配置如下所示：Spring批处理分区作业聚合问题当我启动服务器时，我会看到以下日志消息(我正在尝试使用JMS响应运行(。
Caused by: org.springframework.integration.handler.support.MessagingMethodInvokerHelper$IneligibleMethodException: Found more than one parameter type candidate: [org.springframework.batch.core.partition.StepExecutionSplitter] and [org.springframework.batch.core.StepExecution]
结果是消息聚合无法按预期工作。我看到的不是所有返回消息都进入AggregatorMessageHandler中的单个MessageStore，而是进入两个MessageStore。日志记录清楚地显示了添加消息，将传入消息分为两个不同的组。(为了提高可读性，我缩短了消息的内容(。

这是由于启动时的调试消息吗？我该如何解决这个问题？据我所知，以下是通过JMS配置分区作业的示例。(春季批次4.1(
提前感谢您的任何建议。
尝试使用method="aggregate"为分区处理程序配置聚合器。看起来解析器也试图使用来自MessageChannelPartitionHandler的handle(StepExecutionSplitter, StepExecution)作为候选。
