Question

尽管有一些相当清楚的示例，但我无法手动配置Spring Boot应用程序以使其正常工作。我通常允许它直接从application.properties文件进行配置，但是要求要求我使用多个数据源。而且，是的，我尝试按照此处看到的帖子的建议重新创建Baeldung示例（https://www.baeldung.com/spring-data-jpa-multiple-databases）。这是我的配置：

@Configuration
@EnableJpaRepositories(basePackages = "com.ezcorp.costumerrefresh.db.sqlserver", entityManagerFactoryRef = "sqlserverEntityManagerFactory", transactionManagerRef = "sqlserverTransactionManager")
@EnableTransactionManagement
public class SqlServerConfig {

    @Bean(name="sqlserverDataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    @Primary
    public DataSource sqlserverDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        dataSource.setUrl("jdbc:sqlserver://aswn-tbd-db01:1433;databaseName=DE_RTDS");
        dataSource.setUsername("cs_user");
        dataSource.setPassword("cs_user");
        return dataSource;
    }

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean sqlserverEntityManagerFactory(final EntityManagerFactoryBuilder builder) {
        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.dialect", "org.hibernate.dialect.SQLServer2008Dialect");
        return builder
            .dataSource(sqlserverDataSource())
            .properties(properties)
            .packages("com.ezcorp.costumerrefresh.domain.sqlserver")
            .persistenceUnit("adminPersistenceUnit")
            .build();
    }

    @Bean
    @Primary
    public JpaTransactionManager sqlserverTransactionManager(@Qualifier("sqlserverEntityManagerFactory") final EntityManagerFactory factory) {
        return new JpaTransactionManager(factory);
    }

}

服务：

@Service
public class CustomerRefreshService {
    @Autowired
    private ExistingLoanModelDataRepository existingLoanModelDataRepository;

    public void execute() {
        System.out.println("show me");
    }
}

存储库：

@Repository
public interface ExistingLoanModelDataRepository extends CrudRepository<ExistingLoanModelData, Long> {
    ExistingLoanModelData findByCustomerId(Long customerId);
}

错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.ezcorp.customerrefresh.db.sqlserver.ExistingLoanModelDataRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    ...

我在做什么错？这几乎是直截了当的。为了简化起见，我消除了其他（mongo）配置设置。这必须是显而易见的...对我而言不是：-）

看起来像错字。

@EnableJpaRepositories（basePackages =“ com.ezcorp.cost u merrefresh.db.sqlserver”，entityManagerFactoryRef =“ sqlserverEntityManagerFactory”，transactionManagerRef =“ sqlserverTransactionManager”）

Spring Boot手动配置不扫描存储库对象？
