Java Spring引导jpa数据使用错误的数据库

我有一个SpringBoot应用程序，它拉入一个jar，它有两个数据库配置，都是mysql数据库。这两个数据库在日志中看起来都已正确启动，但没有唯一标识。看起来默认值已注册，然后又重新注册，因此它似乎要覆盖

我有两个用于配置数据库连接的类，它们都位于导入的jar中，基本上是一个公共库

@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:/${app.execution.environment}/application.properties" })
@EnableJpaRepositories(basePackages = "com.example", entityManagerFactoryRef = "mysqlEntityManager", transactionManagerRef = "mysqlTransactionManager")
@EntityScan(basePackages = { "com.example" })
public class MysqlHibernateConfig {
// beans configured here marked with @Primary
...
}

及

我尝试通过以下类从每个数据库获取数据：

@Transactional("mysqlTransactionManager") // workspace complains about not being able to find this bean
@Service
public class PriceService {
}

@Transactional("mysqlTransactionManager2") // workspace complains about not being able to find this bean
    @Service
    public class PriceService2 {
    }

PriceService可以很好地获取数据，但PriceService2尝试从mysqlTransactionManager而不是从mysqlTransactionManager获取数据

我还有以下类来运行我的启动应用程序：

@Configuration
@ComponentScan(basePackages = "com.example")
public class WebMvcConfig extends WebMvcConfigurerAdapter {
//config stuff
}

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

如何强制一个类使用特定的事务管理器/数据源？我一直在尝试各种配置，据我所知，这是正确设置的。如果我把这两个数据源配置类都放进我的spring boot应用程序中，我就可以连接到正确的数据源，没有问题。但当我把它们搬到外面的图书馆时，它就不起作用了。由于我的项目的结构，我必须将它们保存在一个公共库中，两个单独的应用程序使用此数据库配置

如果必要的话，我可以自由地将非主db移动到我的spring boot应用程序中，但这也不起作用。结果也是一样。

在这里，您似乎在jpa存储库级别遇到了冲突。相同的存储库包由不同的

EntityManager

|

TransactionManager

覆盖，因此您应该将存储库放在不同的包中，并在不交叉的情况下重新配置存储库。此外，我还会检查

EntityManager

|

TransactionManager

的bean声明。我在那里放了一些示例，但我的数据源配置类中basePackages的实际结构更像这个com.example和com.example.com.u包，它们是分开的，但一个可能重叠，第一个更通用。编辑将更接近我真正想要的have@Sergi如果我尝试将实体移动到另一个包中，我会在所有已移动的实体上获得“非托管类型”。尝试将@EntityScan添加到指向新包的我的配置中，但仍然无法让它拾取新实体。

@Configuration
@ComponentScan(basePackages = "com.example")
public class WebMvcConfig extends WebMvcConfigurerAdapter {
//config stuff
}

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}
