使用来自不同数据库的bean Hibernate DuplicateMappingException

Question

编辑：我今天早上意识到这个异常似乎与Spring引导执行器有关，它似乎只在生产中运行，而不是在从Spring工具套件中启动prohect时运行。（请参见文章末尾的异常跟踪）

主数据库是使用jpa访问的，关于该数据库的所有内容都在一个特定的包中。

另一个数据库用于直接使用Hibernate访问遗留bean。关于那些遗留bean的一切都在一个不同的包中。

有些bean在两个包中具有相同的名称，但是由于它们是在两个不同的存储库中配置的，所以我认为这不会是一个问题。

    package fr.mycompany.dbconfprimary;

...
...

@Configuration
@EnableJpaRepositories(
        basePackages = "fr.mycompany.dbconfprimary",
        entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager",
        repositoryBaseClass = BaseRepositoryImpl.class)
public class HibernatePrimaryConfig {
    ...
    ...

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em
        = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource());
        em.setPackagesToScan(
                new String[] { "fr.mycompany.dbconfprimary" });

        HibernateJpaVendorAdapter vendorAdapter
        = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<>();

        properties.put("hibernate.hbm2ddl.auto",ddlMode);
        properties.put("hibernate.dialect",dialect);
        em.setJpaPropertyMap(properties);

        return em;
    }

    @Primary
    @Bean
    public PlatformTransactionManager transactionManager() {

        JpaTransactionManager transactionManager
        = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(
                entityManagerFactory().getObject());
        return transactionManager;
    }

    @Primary
    @Bean("serversDataSource")
    public DataSource dataSource() {

        DriverManagerDataSource dataSource
          = new DriverManagerDataSource();
        dataSource.setDriverClassName(driverClassName);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);

        return dataSource;
    }   

}

下面是辅助数据库的配置：

    package fr.mycompany.dbconfsecondary;
...
...

@Configuration
@EnableJpaRepositories(
        basePackages = {"fr.mycompany.dbconfsecondary"}, 
        entityManagerFactoryRef = "secondaryEntityManagerFactory", 
        transactionManagerRef = "secondaryTransactionManager")
public class HibernateSecondaryConfig {
...
...

    @Bean
    public LocalContainerEntityManagerFactoryBean secondaryEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em
        = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(secondaryDataSource());
        em.setPackagesToScan(
                new String[] {"fr.mycompany.dbconfsecondary");

        String[] hbmFiles=new String[hibernateHbmResources.length];
        for(int i=0;i<hibernateHbmResources.length;i++)
            try {
                hbmFiles[i]=convertHbmPath(hibernateHbmResources[i].getFile().getAbsolutePath());
            } catch (IOException e) {
                throw(new RuntimeException(e));
            }
        em.setMappingResources(hbmFiles);

        HibernateJpaVendorAdapter vendorAdapter
        = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<>();

        properties.put("hibernate.hbm2ddl.auto",ddlMode);
        properties.put("hibernate.dialect",dialect);
        properties.put("hibernate.current_session_context_class","thread");

        em.setJpaPropertyMap(properties);

        return em;
    }

    @Bean
    public PlatformTransactionManager secondaryTransactionManager() {

        JpaTransactionManager transactionManager
        = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(
                secondaryEntityManagerFactory().getObject());
        return transactionManager;
    }

    @Bean("secondaryServersDataSource")
    public DataSource secondaryDataSource() {

        DriverManagerDataSource dataSource
          = new DriverManagerDataSource();
        dataSource.setDriverClassName(driverClassName);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);

        return dataSource;
    }   
...
...

}

Answer 1

问题是您应该直接禁用默认的Spring Data JPA存储库初始化。

这可以通过指定spring.data.jpa.repositories.enabled=false配置属性（通过启动参数或application.properties)来实现
