我正在使用Tomcat，Mysql5，Java8在Spring中开发一个应用程序......问题是我无法部署它，因为“必需的bean”没有找到entityManagerFactory的问题。我与同事开发了这个项目，但即使我在Spring Tool Suite中复制粘贴了相同的项目，他们也可以完美地部署它。怎么可能？ 错误：Spring Data JPA-考虑在你的配置中定义一个名为'entityManagerFactory'的bean

@SpringBootApplication
public class ClienteSpringApplication {
public static void main(String[] args) {

如何看起来你的类的主要方法是什么？它是用'@ SpringBootApplication'注解的吗？它是否是其他包的根包？ –
