推荐答案

您的代码应该可以正常工作.这个非常常见的 POI 错误的原因是您的类路径上的库的旧版本，其中该方法尚不存在.而且库中的某些版本的零件也不兼容.

Your code should work properly. The reason of this very common POI error is that an older version of the library on your classpath in which the method didn't exist yet. And also some versions of parts from the library are incompatible.

如果您使用 maven，则这段代码只需要这些依赖项:

If you use maven you need only these dependencies for this piece of code:

<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>poi</artifactId>
  <version>${poi.version}</version>
</dependency>
<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>poi-scratchpad</artifactId>
  <version>${poi.version}</version>
</dependency>

确保您没有额外版本的 jar.

Make sure you do not have extra versions of jars.
