我添加了以下所有 JAR 文件： commons-io-2.5 jai-imageio-core-1.3.1 jna-4.4.0 jna-平台-4.4.0 七月到 slf4j-1.7.2 lept4j-1.6.0 logback-classic-1.2.3 logback-core-1.2.3 selenium-server-standalone-2.7.0-patched-sources slf4j-api-1.7.5 tess4j-3.4.0

请有人帮我解决这个问题.. 谢谢。

错误是由于在您的项目设置中没有正确引用所需的 dll 文件。对于 Eclipse 中的 tess4j 项目，您可以在运行配置中的 VM 参数中添加一行，将 dll 文件放在“dlls”文件夹中，并将文件夹保存在项目的根文件夹中，在 Eclipse 工作区中：

-Djna.library.path=${workspace_loc:/name_of_your_project}/dlls

对于 64 位运行时，dll 文件是 gsdll64.dll、liblept168.dll 和 libtesseract302.dll。 dll 文件已经捆绑在 win32 文件夹中的 tess4j jar 中，您可以如上所述提取并添加到您自己的 dll 文件夹中。
