基本上我有一个输入文件和多个输出文件。我从包含10行的输入文件中读取数据,并希望将数据以3个块的形式写入多个输出文件。在我的情况下,将有4个文件3/3/3/1。每个区块将有一个文件。
作业正常工作,但输出文件的内容错误。
每个文件都包含在当前块中读取bean的最后一个元素
假设第一个区块读取A、B和C。当这个区块写入文件时,只有C被写入,并且被写入3次
根据我的测试,只有当区块提交间隔为1时,它才能正常工作
这是正确的行为吗?
我做错了什么
提前感谢您您的Customer5ToBean应该有scope原型。目前它是一个单例,因此bean属性将始终被最后一项覆盖。是!我不知道我怎么会错过。非常感谢你!
