我在spring spring hibernate应用程序中使用了两个不同的数据库。
我定义了两个持久性配置文件来创建两个会话工厂。 当我启动servlet容器时,它会抛出异常
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionManager' defined in class path resource
PersistenceConfig1
@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:persistence.properties" })
@ComponentScan({ "com.test.test2.*" })
public class PersistenceConfiguration1 {
@Autowired
private Environment env;
@Bean(name="fSessionFactory")
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(testDataSource());
sessionFactory.setPackagesToScan(new String[] {
" com.test.test2"});
sessionFactory.setHibernateProperties(hibernateProperties1());
return sessionFactory;
}
@Bean
public DataSource testDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getProperty("jdbc.url"));
dataSource.setUsername(env.getProperty("jdbc.user"));
dataSource.setPassword(env.getProperty("jdbc.pass"));
return dataSource;
}
@Bean
@Autowired
public HibernateTransactionManager transactionManager(
SessionFactory sessionFactory) {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(sessionFactory);
return txManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
Properties hibernateProperties1() {
return new Properties() {
{
setProperty("hibernate.hbm2ddl.auto",
env.getProperty("hibernate.hbm2ddl.auto"));
setProperty("hibernate.dialect",
env.getProperty("hibernate.dialect"));
setProperty("hibernate.globally_quoted_identifiers", "true");
}
};
}
}
持久性配置2
@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:persistence.properties" })
@ComponentScan({ "com.test.test3.*" })
public class PersistenceConfigurationDOTC {
@Autowired
private Environment env;
@Bean(name="dSessionFactory")
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(test1DataSource());
sessionFactory.setPackagesToScan(new String[] {
"com.test.test3.entity"});
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
@Bean
public DataSource test1DataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("jdbc1.driverClassName"));
dataSource.setUrl(env.getProperty("jdbc1.url"));
dataSource.setUsername(env.getProperty("jdbc1.user"));
dataSource.setPassword(env.getProperty("jdbc1.pass"));
return dataSource;
}
Properties hibernateProperties() {
return new Properties() {
{
setProperty("hibernate.hbm2ddl.auto",
env.getProperty("hibernate.hbm2ddl.auto"));
setProperty("hibernate.dialect",
env.getProperty("hibernate.dialect"));
setProperty("hibernate.globally_quoted_identifiers", "true");
}
};
}
}
如果我定义了两个事务管理器,我也会获得异常。 帮助我了解如何在一个Spring hibernate应用程序中配置两个事务管理器。
答案 0 :(得分:0)
你想要两个配置的单个事务管理器吗?或者你更喜欢多配置?尝试在Persistence Config 2中定义事务管理器。
