完整代码Github repo
我正在使用版本为 2.1.0.RELEASE
的SpringBoot答案 0 :(得分:1)
您的测试正在使用entityManagerFactory
bean加载JPA。在您的主应用程序类中,我认为您已经编写了@EnableJpaRepositories
,如果您的存储库位于主应用程序的基本包下,则不需要这样做。删除此注释,因为您的测试类仅应用于测试Web层。
答案 1 :(得分:0)
尝试像这样向项目添加配置类:
@Configuration
@EnableJpaRepositories(basePackages = "com.webservices.example.librarydatabaseservice.repository")
public class RepositoryConfiguration {
}
问题与您的测试无关。 Spring已经启动并加载了服务,这是一个问题。在Mockito版本的测试中,您不需要它加载所有类并模拟服务/存储库,从而掩盖了问题。在另一版本的测试中,SpringRunner需要加载您的applicationContext,由于缺少JPA配置,该加载失败。
