Java 如何在wso2cep 4.0.0中添加自定义输入事件接收器？

我正在尝试基于wso2cep 4.0.0文档和来自cep/repository/components/plugins的filetail输入事件接收器的反编译版本创建一个自定义输入事件接收器。（）

到目前为止，我已经设法添加了反编译版本中的所有类，并在此基础上构建了一个项目。在cep_home/repository/components/dropins中复制它之后，我尝试启动cep服务器，然后遇到以下问题：

我不明白为什么在最初编译的适配器中，该类是相同的，它可以工作，而在我的情况下它不能

有人能帮我吗？？多谢各位

（如果您需要有关此问题的任何其他信息，请在评论中告诉我，谢谢）

经过进一步的研究，多亏了Dilini（谢谢！），我成功地发现出现了错误，因为我错误地配置了Resources文件夹

src/main/resources/org/wso2/event/adapter/multiplefiletail/i18n/resources

而不是

src/main/resources/org/wso2/carbon/event/input/adapter/multiplefiletail/i18n/resources

---

就像在出现错误的MultipleFileTailEventAdapterFactory类中配置的一样。希望有帮助

Resources.properties文件是否在参考资料下，如中？您好，除了具有版权的注释，已授权给apache等。这几乎是一样的。我修改了一些内容以适合我的适配器，明天如果您愿意，我可以添加它。谢谢你，这是我的资源。属性：

filepath=Source Files Folder filepathHint=这是包含事件文件的文件夹filepattern=文件模式filepatternHint=这是要处理的文件的模式procfolder=已处理的文件Folder procfolderHint=这是将已处理的事件文件移动到分隔符=字段分隔符的文件夹separatorHint=这是相应文件中的字段分隔符numberFields=字段数numberFieldsHint=相应文件中的字段数

，该文件位于与您提供的链接相同的位置。您好，我犯了一个错误，resources文件夹与ServiceDS的路径不匹配，现在它正在工作..谢谢。您好，很高兴你成功了：）
