使用Spring data Jpa 时遇到 java.lang.ClassNotFoundException: org.springframework.core.ReactiveTypeDescriptor

背景

  原本项目是使用SSM+Maven进行开发,而后想同时使用Jpa(即mybatis和jpa混用),配置好相关文件后,使用Junit做测试时,出现以下错误。

主要:

ERROR - Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@29774679] to prepare test instance [jpa.JpaTest@28eaa59a]
java.lang.IllegalStateException: Failed to load ApplicationContext
......
Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [beans.xml]; nested exception is java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: org/springframework/core/ReactiveTypeDescriptor
.......
Caused by: java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: org/springframework/core/ReactiveTypeDescriptor
.......
Caused by: java.lang.NoClassDefFoundError: org/springframework/core/ReactiveTypeDescriptor

Caused by: java.lang.ClassNotFoundException: org.springframework.core.ReactiveTypeDescriptor

[注]:org.springframework.core.ReactiveTypeDescriptor在Spring 5中才有

原因及解决:maven中引入的spring-data-jpa的版本太高(原本我用2.1.3则报以上错误),后换成1.7.0则解决

附:
