我在SpringBoot JPA中编写单元测试，但我一直收到此错误 “没有定义名为'entityManagerFactory'的bean”。我的理解是，Spring Boot应该自动从application.yml文件属性创建EntityManager，并且我在application.yml文件中定义了数据源属性
spring:
profiles: xxxx
datasource:
url: jdbc:postgresql://localhost:5432/minglechat?currentSchema=public
username: postgres
password: abc123
jpa:
generate-ddl: false
hibernate.ddl-auto: create-only
show-sql: true
这是错误堆栈跟踪

defining a bean named 'entityManagerFactory' in your configuration.

我尝试以编程方式创建EntityManager，但仍然遇到相同的错误

dataSource.setDriverClassName("org.postgresql.Driver");
dataSource.setUrl("jdbc:postgresql://localhost:5432/minglechat?currentSchema=public");
dataSource.setUsername("postgres");
dataSource.setPassword("abc123");
return dataSource;
}
@Bean(name={"entityManagerFactory"})
public EntityManager entityManager() {
return entityManagerFactory().getObject().createEntityManager();
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan("com.infor.mingle.entities");
return em;
}
}
