使用Spring和Hibernate进行事务管理会导致非活动事务

Question

我正在使用Spring和Hibernate管理Java Web应用程序.我使用Spring和Hibernate工具来处理持久性级别,所以我不需要提交\ rollback我的事务.应用程序是并发的,因此用户可以修改相同的记录,我决定使用Read Committed隔离级别.

问题是有时我在日志中发现JDBC错误,并且所有下一个请求都出现相同的错误,阻止了应用程序行为.

这些是事务管理中涉及的组件:

@Bean
    public SpringLocalSessionFactoryBean sessionFactory(DataSource dataSource){
        SpringLocalSessionFactoryBean bean = new SpringLocalSessionFactoryBean();
        bean.setConfigLocation(new ClassPathResource("hibernate.cfg.xml"));
        bean.setDataSource(dataSource);
        return bean;
    }

    @Bean
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory){
        HibernateTransactionManager tm = new HibernateTransactionManager();
        tm.setSessionFactory(sessionFactory);
        return tm;
    }

在db session监视器中,当这个东西发生时,我得到了一个INACTIVE事务.

我得到的错误如下:

WARN  - (SqlExceptionHelper.java:144) - SQL Error: 0, SQLState: null
14/03/2016 15:46:06 - ERROR - (SqlExceptionHelper.java:146) - Connection oracle.jdbc.driver.T4CConnection@1a6d7ad6 is closed.

问题是事务和连接应该自动打开和关闭......我希望并发修改失败的事务得到回滚......但似乎它们变得不活跃.

我附上了我的hibernate配置.

<?xml version='1.0' encoding='utf-8'?>
<!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.Oracle10gDialect</property>

<!--        <property name="hibernate.hbm2ddl.auto">update</property> -->
        <property name="hibernate.connection.isolation">2</property>

        <!-- Disable the second-level cache -->
        <property name="hibernate.cache.use_second_level_cache">false</property>
        <property name="hibernate.id.new_generator_mappings">true</property>
        <property name="hibernate.connection.autocommit">false</property>

        <!-- Show and print nice SQL on stdout -->
        <property name="hibernate.show_sql">false</property>
        <property name="hibernate.format_sql">false</property>
        <property name="hibernate.use_sql_comments">false</property>
        <property name="hibernate.generate_statistics">false</property>

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

作为连接库,我使用ojdbc.任何帮助将不胜感激.我不知道在哪里检查.

PS:我补充一点,这个错误每2天产生一次.

编辑:只是另一个集成,这是我在我的server.xml上,它可能与这里的东西有关？

  <Resource name="jdbc/ToolSfDB" global="jdbc/ToolSfDB" auth="Container" type="javax.sql.DataSource"
      driverClassName="oracle.jdbc.OracleDriver"
      url="jdbc:oracle:thin:@//oracle01-internal.local:1521/orcl01"

      minEvictableIdleTimeMillis="60000"

你说I add that this error spawns like once every 2 days.如果你的数据库流量很高，我认为管理连接池，例如使用C3P0和管理总连接、超时...等

例如

<property name="hibernate.c3p0.timeout">500</property>

此空闲连接将从池中删除（500 秒）
