FlatFileItemReader 使用 FixedLengthTokenizer 不起作用

Question

我正在 SpringBatch 中使用带有 FixedLengthTokenizer 的 FlatFileItemReader 来从文本文件中读取并保存到 xml 文件中。我收到一个错误：Bean 属性 'fixedLengthTokenizer' 不可写或具有无效的 setter 方法。setter 的参数类型是否与 getter 的返回类型匹配？（我会放孔控制台日志）。感谢您的任何帮助 。配置文件：spring-batch-context.xml：

在配置 spring bach 文件中： spring-batch-context.xml ：我改变了这个：<property name="fixedLengthTokenizer">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<bean class="org.springframework.batch.item.file.transform.FixedLengthTokenizer">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <property name="names" value="fisrtName,id, phone,lastName ,streetName,age,city, date_of_birth,quantity,sin ,code"></property>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <property name="columns" value="1-4,6-9,10-13,15-18,19-22,23-26,27-31,33-40,45-47,48-53,55-55"></property>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</bean>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </property>到 ：<property name="lineTokenizer">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<bean class="org.springframework.batch.item.file.transform.FixedLengthTokenizer">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <property name="names" value="fisrtName,id, phone,lastName ,streetName,age,city, date_of_birth,quantity,sin ,code"></property>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <property name="columns" value="1-4,6-9,10-13,15-18,19-22,23-26,27-31,33-40,45-47,48-53,55-55"></property>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</bean>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </property>它工作正常。
