我一直试图让多个数据库系统在同一个春季启动项目中工作的时间超过应该的时间。我一直遇到以下异常，需要有更多的目光来推动我修复。
我为下面的大量代码道歉，但由于我不确定问题实际发生在哪里，我将其列在下面。
一个注意事项：我使用专有的ERP数据库作为端点之一。此端点是Oracle数据库，只读。如果需要，我们可以将其切换到MySQL端点，但是我的用例需要ERP的端点才能使项目成功。
使用的资源：
我确定我的答案可能仍然存在于上述问题中，但我现在距离问题太近了，这是我需要帮助的地方。
例外：
java.lang.IllegalArgumentException: Not a managed type: class com.xxx.ddbo.suiteanalytics.objects.ReturnsReasonBrand

答案 0 :(得分：1)
entityManagerFactory -> packages应指向您的托管实体的包。在这里，您指向com.xxx.ddbo.suiteanalytics.interfaces而不是com.xxx.ddbo.suiteanalytics.objects，其中包含实体管理器要管理的所有实体。更新nsEntityManagerFactory中SuiteAnalyticsConfig的包名称。
return builder
.dataSource(dataSource)
.properties(properties)
.packages("com.xxx.ddbo.suiteanalytics.objects")
.persistenceUnit("foo")
.build();
请务必同时更新entityManagerFactory至PostgresqlConfig包中的ddbo.postgresql.objects的包名称
根据配置文件，数据源的配置属性也应该包含 datasource ，例如
@ConfigurationProperties(prefix="spring.postgresql.datasource")
从@EnableJpaRepositories删除DdboApplication。
需要修复包结构或者需要更新ComponentScan以找到弹簧组件。
