我正在尝试使用带有 PoiItemReader 的 spring-批处理扩展（spring-批处理-excel）来读取 excel 罚款。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;
}
这里是 pom 依赖项
<dependency>
<groupId>org.springframework.batch.extensions</groupId>
<artifactId>spring-batch-excel</artifactId>
<version>0.1.0</version>
</dependency>
示例 Excel 我正在尝试读取的文件
看来您需要自己为 poi jar 添加显式依赖项 - 它们在 https://github.com/spring-projects/spring-batch-extensions/blob/main/spring-batch-excel/pom.xml
中标记为可选
