Question

我想使用2个hibernate数据库连接。我正面临这个错误，我试图解决，但无法找到方法。我已经制作了两个不同的配置文件，并注释了@bean和@qualifires，但它仍然有效。

错误

By

我的配置：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionManager' defined in class path resource [com/project/configuration/RepositoryConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.hibernate.SessionFactory]: : No qualifying bean of type [org.hibernate.SessionFactory] is defined: expected single matching bean but found 2: sessionFactory2,sessionFactory; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] is defined: expected single matching bean but found 2: sessionFactory2,sessionFactory

}

第二次配置：

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:hibernate.properties" })
public class RepositoryConfig2 {

@Autowired
private Environment environment;

@Bean(name="sessionFactory2")
public LocalSessionFactoryBean sessionFactory2() {
    LocalSessionFactoryBean sessionFactory2 = new LocalSessionFactoryBean();
    sessionFactory2.setDataSource(dataSource2());
    sessionFactory2.setHibernateProperties(hibernateProperties());
    sessionFactory2.setPackagesToScan(new String[] { "com.project" });
    return sessionFactory2;
}

@Bean
public Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect2"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql2"));
    properties.put("hibernate.hbm2ddl.auto", "update");// environment.getRequiredProperty("hibernate.hbm2ddl.auto")
    return properties;
}

@Bean(name = "datasource2")
public DataSource dataSource2() {
    DriverManagerDataSource dataSource2 = new DriverManagerDataSource();
    dataSource2.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName2"));
    dataSource2.setUrl(environment.getRequiredProperty("jdbc.url2"));
    dataSource2.setUsername(environment.getRequiredProperty("jdbc.username2"));
    dataSource2.setPassword(environment.getRequiredProperty("jdbc.password2"));
    return dataSource2;
}


@Autowired
@Qualifier(value = "sessionFactory2")
public HibernateTransactionManager transactionManager(SessionFactory s) {
    HibernateTransactionManager txManager2 = new HibernateTransactionManager();
    txManager2.setSessionFactory(s);
    return txManager2;
}

}

好的，我做了更多的R＆amp; D，幸运的是我解决了这个问题..

所以这就是我做的事情

将我的RepositoryConfiguration合并到一个类中。
从HibernateTransactionManager中移除了自动装配并手动连接了sessionFactories。
还扫描用于扫描hibernate的cjanged包（意识到它将在两个数据库中创建相同的表）

在@Transactional中添加限定符（从spring导入。）

@Transactional("sessionFactoryTransactionManager")

在我的存储库中。

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:hibernate.properties" })
public class RepositoryConfiguration {

@Autowired
private Environment environment;

@Bean(name = "sessionFactory")
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setHibernateProperties(hibernateProperties());
    sessionFactory.setPackagesToScan(new String[] { "com.project" });
    return sessionFactory;
}

@Bean
public Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect",    environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
    properties.put("hibernate.hbm2ddl.auto", "update");// environment.getRequiredProperty("hibernate.hbm2ddl.auto")
return properties;
}

@Bean(name = "sessionFactory2")
public LocalSessionFactoryBean sessionFactory2() {
    LocalSessionFactoryBean sessionFactory2 = new  LocalSessionFactoryBean();
    sessionFactory2.setDataSource(dataSource());
    sessionFactory2.setHibernateProperties(hibernateProperties2());
    sessionFactory2.setPackagesToScan(new String[] { "com.server" });
    return sessionFactory2;
}

@Bean
public Properties hibernateProperties2() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect2"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql2"));
    properties.put("hibernate.hbm2ddl.auto", "update2");// environment.getRequiredProperty("hibernate.hbm2ddl.auto")
    return properties;
}

@Bean(name = "datasource2")
public DataSource dataSource2() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName2"));
       dataSource.setUrl(environment.getRequiredProperty("jdbc.url2"));
   dataSource.setUsername(environment.getRequiredProperty("jdbc.username2"));
   dataSource.setPassword(environment.getRequiredProperty("jdbc.password2"));
    return dataSource;
}

@Bean(name = "datasource")
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
    }

@Autowired
@Qualifier("sessionFactory")
private SessionFactory sessionFactory;

@Autowired
@Qualifier("sessionFactory2")
private SessionFactory sessionFactory2;

@Bean(name = "sessionFactoryTransactionManager")
public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(this.sessionFactory);
     return txManager;
}

@Bean(name = "sessionFactory2TransactionManager")
 public HibernateTransactionManager transactionManager2() {
    HibernateTransactionManager txManager2 = new HibernateTransactionManager();
    txManager2.setSessionFactory(this.sessionFactory2);
    return txManager2;
}

}

使用2个hibernate sessionFactories的Spring配置
