Question

我正在使用带有两个数据源的spring-data-jpa，但我的两个架构elettroforesi和capillare都有一个表ANALISI

和Eclipse向我显示以下错误：

"Duplicate entity name "Analisi" found in the persistence unit. Entity names must be unique."

Config如下：

@Configuration
@PropertySource({ "classpath:persistence-multiple-db.properties" })
@EnableTransactionManagement
@EnableJpaRepositories(
        basePackages = "com.interlabsrl.elfolab.persistence.multiple.repository.elettroforesi", 
        entityManagerFactoryRef = "elettroforesiEntityManager", 
        transactionManagerRef = "elettroforesiTransactionManager")
@ComponentScan(basePackages={"com.interlabsrl.elfolab.controller",
        "com.interlabsrl.elfolab.persistence.multiple.service", 
        "com.interlabsrl.elfolab.persistence.multiple.cache"})
public class ElettroforesiConfig {

    @Autowired
    private Environment env;

    public ElettroforesiConfig() {
        super();
    }

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean elettroforesiEntityManager() {
        final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setPersistenceUnitName("elettroforesi");
        em.setDataSource(elettroforesiDataSource());
        em.setPackagesToScan(new String[] { "com.interlabsrl.elfolab.persistence.multiple.model.elettroforesi" });
        final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        final HashMap<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
        properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", env.getProperty("hibernate.format_sql"));
        properties.put("hibernate.jdbc.batch_size", env.getProperty("hibernate.jdbc.batch_size"));
        em.setJpaPropertyMap(properties);
        return em;
    }

    @Bean
    @Primary
    public DataSource elettroforesiDataSource() {
        final DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(Preconditions.checkNotNull(env.getProperty("jdbc.driverClassName")));
        dataSource.setUrl(Preconditions.checkNotNull(env.getProperty("elettroforesi.jdbc.url")));
        dataSource.setUsername(Preconditions.checkNotNull(env.getProperty("elettroforesi.jdbc.user")));
        dataSource.setPassword(Preconditions.checkNotNull(env.getProperty("elettroforesi.jdbc.pass")));
        return dataSource;
    }

    @Bean
    @Primary
    public PlatformTransactionManager elettroforesiTransactionManager() {
        final JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(elettroforesiEntityManager().getObject());
        return transactionManager;
    }

}

和

@Configuration
@PropertySource({ "classpath:persistence-multiple-db.properties" })
@EnableTransactionManagement
@EnableJpaRepositories(
        basePackages = "com.interlabsrl.elfolab.persistence.multiple.repository.capillare",

        transactionManagerRef = "capillareTransactionManager")
@ComponentScan(basePackages={"com.interlabsrl.elfolab.controller",
//      , "com.interlabsrl.elfolab.persistence.multiple.service" 
//      "com.interlabsrl.elfolab.persistence.multiple.cache"
        })
public class CapillareConfig {

    @Autowired
    private Environment env;

    public CapillareConfig() {
        super();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean capillareEntityManager() {
        final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setPersistenceUnitName("capillare");
        em.setDataSource(capillareDataSource());
        em.setPackagesToScan(new String[] { "com.interlabsrl.elfolab.persistence.multiple.model.capillare" });
        final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        final HashMap<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));

        properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", env.getProperty("hibernate.format_sql"));
        properties.put("hibernate.jdbc.batch_size", env.getProperty("hibernate.jdbc.batch_size"));
        em.setJpaPropertyMap(properties);
        return em;
    }

    @Bean
    public DataSource capillareDataSource() {
        final DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(Preconditions.checkNotNull(env.getProperty("jdbc.driverClassName")));
        dataSource.setUrl(Preconditions.checkNotNull(env.getProperty("capillare.jdbc.url")));
        dataSource.setUsername(Preconditions.checkNotNull(env.getProperty("capillare.jdbc.user")));
        dataSource.setPassword(Preconditions.checkNotNull(env.getProperty("capillare.jdbc.pass")));
        return dataSource;
    }

    @Bean
    public PlatformTransactionManager capillareTransactionManager() {
        final JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(capillareEntityManager().getObject());
        return transactionManager;
    }

}

而实体：

    @NamedQuery(name = "Analisi.findAll", query = "SELECT a FROM Analisi a")})

Answer 1

您的实体都被命名为Analisi，尝试将第二个更改为Capillare。您将表命名为Capillare，但该类名为Analisi

Spring-data-jpa在两个数据源上的相同表名“Duplicate entity name”
