如何避免 Apache POI 中的 java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;) [英] How to avoid java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;) in Apache POI

问题描述

我有向现有 .doc 文件添加水印的代码.

I have a code for adding watermark to existing .doc file.

以下是我目前尝试过的代码

The following is the code I have tried so far

public static void main(String[] args)
{

    try
    {
        XWPFDocument xDoc = new XWPFDocument(new FileInputStream("test.doc"));
        XWPFHeaderFooterPolicy xFooter = new XWPFHeaderFooterPolicy(xDoc);
        xFooter.createWatermark("My Watermark");
    }
    catch(Exception e) {
        e.printStackTrace();
    }
}

以下是我得到的

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;)V
at org.apache.poi.util.PackageHelper.open(PackageHelper.java:50)
at org.apache.poi.xwpf.usermodel.XWPFDocument.<init>(XWPFDocument.java:71)
at com.avi.Test.ReadDoc.main(Watermark.java:38)

推荐答案

我今天遇到了这个错误:"java.lang.NoSuchMethodError:org.apache.poi.util.POILogger.log(I[Ljava/lang/Object;)V]"

I got this error today: "java.lang.NoSuchMethodError:org.apache.poi.util.POILogger.log(I[Ljava/lang/Object;)V]"

它看起来与您的错误不同，但非常相似.仅供参考，我正在使用 maven 来管理罐子.经过一些实验，我发现根本情况是poi.jar和poi-ooxml.jar的版本不一致.

It looks different from your error, but quite similar. FYI, I'm using maven to manage jars. After some experiment, I found out the root case is the poi.jar and poi-ooxml.jar's version are not consistent.

这个配置会报错:

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.12</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.13</version>
    </dependency>

我将 poi.jar 的版本从 3.12 更改为 3.13

I changed the version of poi.jar from 3.12 to 3.13

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.13</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.13</version>
    </dependency>
