有人可以帮助我吗？
【问题讨论】：
您使用的是哪个 Hibernate ORM 版本？可能与 Spring Boot 版本不匹配。 好点，我改变 pom 删除排除形式 spring-boot-starter-data-jpa 并删除依赖您正在调用方法testIdDataSourceProperties，而不是bean。
试试这个：
@Bean
@Primary
@ConfigurationProperties("persistence.datasource.xid.hikari")
public DataSource testIdDataSource(@Autowired DataSourceProperties dataSourceProperties)
return dataSourceProperties.initializeDataSourceBuilder().build();
【讨论】：
你好，我已经按照你说的试过了。我收到同样的错误以上是关于错误 - NoSuchBeanDefinitionException：没有名为“entityManagerFactory”的bean可用的主要内容，如果未能解决你的问题，请参考以下文章
