Java 我的实体没有持久化，但我可以很好地从数据库中读取

我刚刚更新到Hibernate4.1.5和Spring3.1.2（从2.6ish和2.5或其他版本…）。我已经成功地将所有内容设置为从现有数据库中读取，并且所有页面都显示良好，但是在提交数据时，没有任何内容被持久化到数据库中。我已将日志记录设置为跟踪级别，以尝试跟踪此问题，事务将从我的日志中提取以下15行：

DEBUG - org.hibernate.internal.SessionImpl - SessionImpl                    - Opened session at timestamp: 13430582784
TRACE - org.hibernate.internal.SessionImpl - SessionImpl                    - Setting flush mode to: AUTO

并称之为：

@SpringBean MyService myService; //(Using wicket @Springbean)
...
MyEntity entity = new MyEntity();
entity.setEnabled(true);
entity.setNotes("blah");
entity.setSubmittedDate(new Date());
myService.persist(entity);

我将web.xml作为：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <filter>
        <filter-name>OpenEntityManagerFilter</filter-name>
        <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>OpenEntityManagerFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

上下文配置位置
类路径：applicationContext.xml
org.springframework.web.context.ContextLoaderListener
开放式管理过滤器
org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter
开放式管理过滤器
/*

最后在applicationContext.xml中：

<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"

           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <tx:annotation-driven/>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

    <context:annotation-config />
    <context:component-scan base-package="ic.services" />
</beans>

再说一次，任何帮助都会很棒。我敢肯定这一定是代表我做的非常愚蠢的事情！：）

尝试将@Transactional添加到持久化服务方法。

太棒了！非常感谢。我在MyServiceImpl类上设置了@Transactional（我忘了提供），但显然这并没有渗透到基类！再次感谢。

@SpringBean MyService myService; //(Using wicket @Springbean)
...
MyEntity entity = new MyEntity();
entity.setEnabled(true);
entity.setNotes("blah");
entity.setSubmittedDate(new Date());
myService.persist(entity);
