Java Spring批处理在使用数据源时崩溃，创建名为jobCompletionNotificationListener的bean时出错

我需要使用SpringBatch来删除一些文件，并将处理后的数据插入我的数据库（OracleDB）。在我添加和配置数据库连接之前，一切都很正常

Application.java入口点

@ComponentScan
@EnableBatchProcessing
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);

MultipleDBConfig.javaBean用于配置数据库。如果我对bean进行注释，一切正常，如果我让它运行，我就会得到错误

您是否正在使用2个数据源？因为SpringBoot会自动配置数据源，如果您有dirver jar，那么您所要做的就是在application.properties中提供属性file@VenuDuggireddy不，我只使用一个数据源，但我认为Spring Batch需要将一些数据保存到DB才能工作，所以如果我不指定任何DB Batch使用其嵌入式数据库，但是，如果我在application.properties批处理中指定了一个数据库，请尝试访问该数据库并保存其日期（这是不需要的）。我试图找到一种方法，告诉Batch使用其嵌入的DB作为数据，不要尝试访问我的数据库database@Ares91-你能解决这个问题吗？@Prateek不，我不能。我切换到多线程
