尝试使用以下方法转换固定文件格式：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
 "id",
 "name",
  .
  .
})
@XmlRootElement(name = "Til")
@FixedLengthRecord(length = 239)
public class Til {

 @XmlElement(name = "ID", required = true)
 @DataField(pos = 1, length = 4)
 protected String id;

 @XmlElement(name = "NAME", required = true)
 @DataField(pos = 5, length = 15)
 protected String name;
 .
 .
}

文件中的总字符数为 239。

这个错误可能是什么原因？修复此问题需要任何类型的修剪或填充？

这可以通过在您的 POJO 类上应用以下代码来克服。这基本上是告诉 Bindy 忽略根据 POJO 映射的最后一个固定长度数据之后的字符。

@FixedLengthRecord(ignoreTrailingChars = true)

启用 View -> Show Symbol -> Show All Characters 后，您也许可以在 notepad++ 中打开文件，然后查看最后是否确实存在任何字符。在处理从不同操作系统生成的文件时，通常会注意到这些字符。您还可以仔细检查映射以确保所有字段实际上都按照正确的长度进行映射，这很容易被忽视。
