java - 移动配置、实体和其他类

Question

我有一个大问题。 我有一个带有 Spring-Boot 和 Spring-Data 的应用程序。 在我移动一些类并重构目录之前一切进展顺利。

我有两个数据库，在移动类之前，我有第二个数据库的配置类:

         @Configuration
      @EnableTransactionManagement
      @EnableJpaRepositories(
         basePackages="it.phoops.rt.grigliaprocessi.util", 
         entityManagerFactoryRef = "organoEntityManager",
         transactionManagerRef = "organoTransactionManager")     
      public class OrganoConfig {

          @Bean(name = "organoDataSource")
           @ConfigurationProperties(prefix="organo.datasource")
          public DataSource organoDataSource(){
                  return DataSourceBuilder.create().build();
           }

          @Bean(name="organoEntityManager")
          public LocalContainerEntityManagerFactoryBean    
       organoEntityManagerFactory(EntityManagerFactoryBuilder builder,
         @Qualifier("organoDataSource") DataSource dataSource){

          return       
 builder.
 dataSource(organoDataSource()).
 packages("it.phoops.rt.grigliaprocessi.util.entity").
  persistenceUnit("organo").build();
 }

           @Bean("organoTransactionManager")

                public PlatformTransactionManager 
 organoTransactionManager()               
 {     
                      return new   
  DataSourceTransactionManager(organoDataSource());
        }

 }

现在，我搬进了“it.phoops.rt.grigliaprocessi.organo”，并将“basePackages”的值从“it.phoops.rt.grigliaprocessi.util”更改为“it.phoops.rt.grigliaprocessi”。有机”和
字符串“it.phoops.rt.grigliaprocessi.util.entity”到 it.phoops.rt.grigliaprocessi.organo.entity”。

我将实体、服务和存储库类移至:

it.phoops.rt.grigliaprocessi.util.controller
it.phoops.rt.grigliaprocessi.util.entity
it.phoops.rt.grigliaprocessi.util.repository

到

it.phoops.rt.grigliaprocessi.organo.controller
it.phoops.rt.grigliaprocessi.organo.entity
it.phoops.rt.grigliaprocessi.organo.repository

但是现在，我遇到了这个错误，是由嵌套异常引起的:

Caused by: java.lang.IllegalArgumentException: Not a managed type: 
class it.phoops.rt.grigliaprocessi.organo.entity.Albero

……

 Caused by: org.springframework.beans.factory.BeanCreationException:

 method failed; nested exception is 
 java.lang.IllegalArgumentException:

...

你能帮我吗？

谢谢

将基础包声明从 it.phoops.rt.grigliaprocessi.util 更改为 it.phoops.rt.grigliaprocessi.organo。另请检查 Spring boot 主类中的 componentScan 中的基础包。
