如何将刷新模式设置为“COMMIT"?在我的配置文件中? [英] How do I set flush mode to "COMMIT" in my configuration files?

问题描述

我使用的是 Spring 3.1.1.RELEASE、Hibernate 4.1.0.Final 和 JPA 2.0.有没有办法在没有 Java 代码的情况下执行事务后配置 Spring 事务以提交?换句话说，我想将刷新模式设置为在应用程序上下文文件、休眠配置文件或persistence.xml 文件中提交.我的 Spring 事务服务类看起来像

I'm using Spring 3.1.1.RELEASE, Hibernate 4.1.0.Final, and JPA 2.0. Is there a way I can configure Spring transactions to commit after the transactions are executed without Java code? In other words, I would like to set flush mode to commit in either the application context file, hibernate configuration file, or persistence.xml file. My Spring transaction service class looks like

@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是这样设置的……

and my application context is set up like so …

<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

My persistence.xml file is

<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>

我的休眠配置文件是

<?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>
