我在Spring和mongodb中使用了hibernate JPA，并且我在Glassfish-4.0上运行我的应用程序。

我的服务类别是：

@Component
public class Test {
    @PersistenceContext
    EntityManager em;
    EntityManagerFactory emf;

    @Transactional
    public String persist(Details details) {
        details.getUsername();
        details.getPassword();

        Query query = em.createNativeQuery("db.details.find(username="+details.getUsername()+"&password="+details.getPassword());

        em.getTransaction().begin();
        em.persist(details);
        em.getTransaction().commit();
        em.flush();
        em.clear();
        em.close();
        query.executeUpdate();
        System.out.println("Sucessful!");
        return "persist";        
    }
}

我的spring-context.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:mvc="http://www.springframework.org/schema/mvc"

    <context:component-scan base-package="com.javapapers.spring.mvc" />
    <context:annotation-config />
    <mvc:annotation-driven />
    <tx:annotation-driven transaction-manager="txManager" />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="ogmTest"/>
    </bean>
    <bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager">
    </bean>
</beans>

我在代码中应用了一些更改，但是它们没有效果。谁能帮我解决这个问题。提前致谢。
