java - NoClassDefFoundError : QuerydslUtils

Question

获取 NoClassDefFoundError: org/springframework/data/querydsl/QuerydslUtils 错误。我正在使用 1.13.6.RELEASE 版本的 spring-data-commons。

堆栈轨迹如下:

Answer 1

正如@himanshuraipur 所述，存在版本冲突:

spring-data-dynamodb 5.0.2 基于 spring-data 2.0/Spring 5。

但是 spring-boot 1.5.6 自带 spring-data 1。

因此，您唯一的机会是更新您的 spring-boot 依赖项或返回到 spring-data-dynamodb 4.5 或 4.6。在项目页面上有一个完整的 compatibilty matrix
