我有一个带有REST API的Spring启动应用程序,我试图通过查询参数使结果集可过滤。看了this article后,我认为QueryDSL可以很好地满足这个要求。
我目前遇到的问题是,在运行时似乎无法访问类...此外,我已经在IntelliJ中明确地将jar添加到类路径
错误
java.lang.NoClassDefFoundError: Could not initialize class com.mysema.query.jpa.HQLTemplates
at org.springframework.data.jpa.repository.support.Querydsl.createQuery(Querydsl.java:83) ~[spring-data-jpa-1.9.2.RELEASE.jar:na]
at org.springframework.data.jpa.repository.support.Querydsl.createQuery(Querydsl.java:98) ~[spring-data-jpa-1.9.2.RELEASE.jar:na]
依赖关系在pom中,因为我使用spring-boot-maven-plugin
它们应该捆绑到工件中。
