java - 添加validation-api-2.0.1.final.jar会出现错误

Question

我在 Spring 创建了简单的验证表单，它仅适用于文件。当我将 hibernate validator 所需的 jar 文件添加到 WEB_INF/lib 时，它给了我一个错误。仅添加 Validation-api-2.0.1.Final.jar 或 hibernate-validator-annotion-processor.6.0.10.Final.jar 给出错误，jar 文件的其余部分工作正常。

Note:-I din't even call the class inside Validation-api-2.0.1.Final.jar

错误:

这取决于您的运行时版本。 validation-api-2.0.1.Final.jar 至少应为 java 8。
