我正在尝试使用带有 PoiItemReader 的 spring-batch 扩展（spring-batch-excel）读取 excel。尝试通过以下配置读取 excel 文件时出现以下错误。
错误：

ItemReader 配置：
@Bean
@Scope(value = "step", proxyMode = ScopedProxyMode.TARGET_CLASS)
public PoiItemReader xlsItemReader() {
PoiItemReader reader = new PoiItemReader();
reader.setResource(new FileSystemResource("/path/to/your/excel/file"));
reader.setRowMapper(new PassThroughRowMapper());
return reader;
}
这是 pom 依赖项
