我试图解决一些问题，但没有成功：所以我来找你，以获得一些线索，以帮助我。我无法在spring batch datasource中正确保存和读取数据，而且它包含一些多态性

最后，我尝试将文档保存如下

@Autowired

@凌驾

公开无效写入（列表
我无法正确保存和读取数据
：您能详细说明一下吗？您是否有错误或stacktrace要共享？或者工作完成时没有错误，但数据没有保存到数据库中？请提供一个复制问题的列表，以便能够有效地帮助您。对于泛型，我不确定您是否可以拥有一个泛型编写器u描述。您可以创建一个通用包装器服务，根据传递对象的类型委托给正确的服务。然后在编写器中使用该包装器服务。关于数据，事实上我有两个步骤。第一个步骤从表a读取数据，然后将数据写入表B。第二个步骤必须从表B读取数据，但没有要获取的数据可以用我最喜欢的工具查看我表上的行蟾蜍：）确定将调查通用包装器。。。
