如何在配置文件中将刷新模式设置为“ COMMIT”？

Question

我正在使用Spring 3.1.1.RELEASE，Hibernate 4.1.0.Final和JPA
2.0。有没有一种方法可以配置Spring事务以在不使用Java代码的情况下执行事务后提交？换句话说，我想将刷新模式设置为在应用程序上下文文件，hibernate配置文件或persistence.xml文件中提交。我的Spring交易服务类看起来像

@Transactional(rollbackFor = Exception.class)
@Service
public class ContractServiceImpl implements ContractService
{

    @Autowired
    private ContractDAO m_contractDao;

    public void addContract(Contract contract)
    {
       m_contractDao.create(contract);
    }

    ...

我的应用程序上下文设置如下：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
    <property name="url" value="jdbc:hsqldb:mem:myproject" />
    <property name="username" value="sa" />
    <property name="password" value="" />
</bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
    </property>
    <property name="persistenceXmlLocation" value="classpath*:META-INF/test-persistence.xml"/>
    <property name="persistenceUnitName" value="testingDatabase"/>
    <property name="dataSource" ref="dataSource"/>
</bean>

<bean id="sharedEntityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
   <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

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

<tx:annotation-driven />

我的persistence.xml文件是

<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="testingDatabase" transaction-type="RESOURCE_LOCAL">
                <provider>org.hibernate.ejb.HibernatePersistence</provider>
                <properties>
                        <property name="hibernate.ejb.cfgfile" value="/hsql_hibernate.cfg.xml" />
        <property name="org.hibernate.FlushMode" value="commit" />
                </properties>
        </persistence-unit>
</persistence>

我的hibernate配置文件是

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.pool_size">1</property>
        <property name="show_sql">true</property>
        <property name="dialect">org.hibernate.dialect.HSQLDialect</property>
        <property name="hibernate.hbm2ddl.auto">create-drop</property>

        <mapping class="org.mainco.subco.sbadmin.domain.Product" />
        <mapping class="org.mainco.subco.sbadmin.domain.Contract" />
        <mapping class="org.mainco.subco.organization.domain.Country" />
        <mapping class="org.mainco.subco.organization.domain.State" />
        <mapping class="org.mainco.subco.organization.domain.Address" />
        <mapping class="org.mainco.subco.organization.domain.OrganizationType" />
        <mapping class="org.mainco.subco.organization.domain.Organization" />

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

您可能需要扩展

org.springframework.orm.jpa.vendor.HibernateJpaDialect

我希望这有帮助！
