使用@StepScope在多步骤Spring批处理应用程序中为JDBCItemReader创建通用实用程序

我已经创建了一个多步骤Spring Batch应用程序。我已经定义了一个单独的实用程序来为每个步骤返回一个JdbcItemReader示例。有什么方法可以使其成为一个泛型函数吗？我已经尝试将其作为一个泛型函数并将@StepScope放在上面，但我得到了下面提供的错误。

这个错误是由createJdbcBatchItemWriter方法引起的：这个方法定义了一个名为createJdbcBatchItemWriter的bean，它有一个Class类型的依赖项，通过方法的参数表示。因为（我猜）在应用程序上下文中没有Class类型的bean，所以这个错误发生了。
尝试删除@Bean和@StepScope，并在需要的地方使用目标类型调用该方法。每次都会得到一个新的writer示例。
