strac 而後 call foreach sun 解決 extension ins match

背景
原本項目是使用SSM+Maven進行開發，而後想同時使用Jpa（即mybatis和jpa混用），配置好相關文件後，使用Junit做測試時，出現以下錯誤。
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

[註]:org.springframework.core.ReactiveTypeDescriptor在Spring 5中才有
原因及解決：maven中引入的spring-data-jpa的版本太高（原本我用2.1.3則報以上錯誤），後換成1.7.0則解決
