Question

我无法导入org.springframework.batch.item.excel.poi.PoiItemReader。它显示以下错误。

我的错误：

我的Pom文件：

npm init
npm i yargs --save

导入org.springframework.batch.item.excel.poi.PoiItemReader无法解析。我在pom文件中明确提到了必需的依赖项。

我需要添加任何其他依赖吗？

Answer 1

否，您不需要其他依赖项。问题是远程Maven存储库中不存在 spring-batch-excel 。因此，您需要在本地Maven缓存中手动安装它。

要这样做：

1。查看春季批量扩展的来源

git clone git://github.com/spring-projects/spring-batch-extensions.git

2。进入spring-batch-excel模块的目录

cd spring-batch-extensions

cd spring-batch-excel

3。编译和测试，构建所有jars

mvn clean package

4。将模块jars安装到本地Maven缓存中

mvn install

现在 spring-batch-excel 存在于本地Maven缓存中。

我自己添加了以下依赖项来解决此问题。

<dependency>
        <groupId>com.github.deanwong</groupId>
        <artifactId>spring-batch-excel</artifactId>
        <version>0.5.5</version>
</dependency>

这是我的pom文件：
