Question

我使用Spring 3.0.6，GlassFish 3.1，EJB 3，JPA 2，我的提供者是EclipseLink（JPA 2.0）

我的webApplication有以下配置文件：

的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="ejb_transportPU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>tranEnterprise</jta-data-source>    
  <properties>
  <property name="eclipselink.target-server" value="SunAS9"/>
  <property name="eclipselink.logging.level" value="FINEST"/>
  <property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.MySQLPlatform"/>
</properties>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
</persistence-unit>
</persistence>

的applicationContext.xml

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

</property>
</bean>
<tx:jta-transaction-manager />
<bean id="persistenceAnnotation" class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
</beans>

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

</session-timeout>
</session-config>

<welcome-file>redirect.jsp</welcome-file>
</welcome-file-list>
</web-app>

我的控制器方法：

 @Transactional
    @RequestMapping(method = RequestMethod.POST)
    public String onSubmit(@ModelAttribute("contract") Contract contract)
    {
        try
        {
            contractBean.creatCotract(contract);                
        } catch (Exception e)
        {
            e.printStackTrace();
        }
        return "someThing";
    }

此项目显示数据，但不会在数据库中保留数据。我搜索了很多个星期，但我找不到任何答案。
