Spring Boot Second DataSource导致无法自动装配字段

Question

我正在尝试使用两个数据源设置Spring Boot应用程序。我已经成功地获得了第一个数据源，但是当我添加类来处理第二个数据源时，第一个数据源不再起作用并导致第一个数据源没有自动装配的DAO，这意味着DOA可以＆＃ 39;加载到我的控制器中。

这是设置第一个数据源的类。

@Configuration
@PropertySource({ "classpath:application.properties" })
@EnableJpaRepositories(
        basePackages = "digital.sheppard.dao.local",
        entityManagerFactoryRef = "localEntityManager",
        transactionManagerRef = "localTransactionManager"
)
public class LocalDBConfig {
    @Autowired
    private Environment env;

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean localEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(localDataSource());
        em.setPackagesToScan(new String[] { "digital.sheppard.model.local" });

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("datasource.local.hibernate.ddl-auto"));
        properties.put("hibernate.dialect", env.getProperty("datasource.local.hibernate.dialect"));
        properties.put("hibernate.naming-strategy", env.getProperty("org.hibernate.cfg.ImprovedNamingStrategy"));
        em.setJpaPropertyMap(properties);


        return em;
    }

    @Primary
    public DataSource localDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(env.getProperty("datasource.local.driver-class-name"));
        dataSource.setUrl(env.getProperty("datasource.local.url"));
        dataSource.setUsername(env.getProperty("datasource.local.username"));
        dataSource.setPassword(env.getProperty("datasource.local.password"));

        return dataSource;
    }

    @Primary
    @Bean
    public PlatformTransactionManager localTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(localEntityManager().getObject());
        return transactionManager;
    }
}

这是尝试设置第二个数据源的类。

    @Configuration
@PropertySource({ "classpath:application.properties" })
@EnableJpaRepositories(
        basePackages = "digital.sheppard.dao.eclipse",
        entityManagerFactoryRef = "eclipseEntityManager",
        transactionManagerRef = "eclipseTransactionManager"
)
public class EclipseDBConfig {
    @Autowired
    private Environment env;

    @Bean
    public LocalContainerEntityManagerFactoryBean eclipseEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(eclipseDataSource());
        em.setPackagesToScan(new String[] { "digital.sheppard.model.eclipse" });

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("datasource.eclipse.hibernate.ddl-auto"));
        properties.put("hibernate.dialect", env.getProperty("datasource.eclipse.hibernate.dialect"));
        properties.put("hibernate.naming-strategy", env.getProperty("org.hibernate.cfg.ImprovedNamingStrategy"));
        em.setJpaPropertyMap(properties);


        return em;
    }

    public DataSource eclipseDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(env.getProperty("datasource.eclipse.driver-class-name"));
        dataSource.setUrl(env.getProperty("datasource.eclipse.url"));
        dataSource.setUsername(env.getProperty("datasource.eclipse.username"));
        dataSource.setPassword(env.getProperty("datasource.eclipse.password"));

        return dataSource;
    }

    @Bean
    public PlatformTransactionManager eclipseTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(eclipseEntityManager().getObject());
        return transactionManager;
    }
}

在我看来，第二个数据源正在覆盖第一个数据源，因此应用程序不再能够找到主数据源中定义的DOA。

为什么我的第二个DataSource会阻止DAO从第一个DataSource再到不再加载？
