spring的beans.xml配置

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

	<bean id="hi"
		class="org.springframework.orm.hibernate4.HibernateTemplate"
		p:sessionFactory-ref="sessionFactory"/>

</beans>

hibernate.cfg.xml配置

<!DOCTYPE hibernate-configuration PUBLIC
	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
	"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
	<session-factory>
		<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>

	</session-factory>
</hibernate-configuration>

使用下面的代码保存数据库时

public class Main {
	public static void main(String[] args) {

		ApplicationContext acx = new ClassPathXmlApplicationContext("beans.xml");
		HibernateTemplate ht = acx.getBean("hi", HibernateTemplate.class);
		ht.saveOrUpdate(new Person("孙悟空", "123456"));
	}
}

出现下面的错误

Exception in thread "main" org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.MANUAL): 
Turn your Session into FlushMode.COMMIT/AUTO or remove ""readOnly"" marker from transaction definition.

这是说只读吗？这个错误怎么样解决？
