Question

我正在使用从相当复杂的模板生成的SpringBoot应用程序。它只是一个通过数据源访问数据库的REST服务。它没有使用JPA。

当我的应用程序启动时，我会看到以下输出（可能与其他类似的问题几乎相同）：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: At least one JPA metamodel must be present!

我已经阅读了其他相关报道的大部分报告，并且我与我的团队中遇到同样问题的其他人进行了核实，我相信我有正确的解决方法，但它已经＃39 ; s仍然无法正常工作。

以下是我的Application类：

@SpringBootApplication
@ComponentScan(basePackages = "com")
//@EnableAsync
//@EnableCaching
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class,
                                     HibernateJpaAutoConfiguration.class,
                                     HazelcastAutoConfiguration.class,
                                     CacheAutoConfiguration.class,
                                     JpaRepositoriesAutoConfiguration.class })
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        new SpringApplicationBuilder().sources(Application.class, AppConfig.class).run(args);
    }
}

在应用程序pom中，我指定＆＃34; spring-boot-starter-web＆＃34;作为依赖。

这里还有什么可能是错的？

需要在SpringBoot应用程序中关闭JPA，获取＆＃34;必须至少存在一个JPA元模型！＆＃34;
