如何将清空模式设置为“COMMIT”在我的配置文件？ [英] How do I set flush mode to "COMMIT" in my configuration files?

问题描述

我使用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事务在事务执行之后提交而没有Java代码？换句话说，我想要在应用程序上下文文件，hibernate配置文件或persistence.xml文件中设置刷新模式。我的Spring事务服务类看起来像

  @Transactional（rollbackFor = Exception.class）
 @Service 
公共类ContractServiceImpl实现ContractService 
 {
 
 @Autowired 
私人ContractDAO m_contractDao; 
 
 public void addContract（Contract contract）
 {
 m_contractDao.create（contract）; 
} 
 
 ... 
  

和我的应用程序上下文是...

 < bean id =dataSourceclass =org.springframework.jdbc.datasource.DriverManagerDataSource > 
< property name =driverClassNamevalue =org.hsqldb.jdbcDriver/> 
< property name =urlvalue =jdbc：hsqldb：mem：myproject/> 
< property name =usernamevalue =sa/> 
< property name =passwordvalue =/> 
< / bean> 
 
< bean id =entityManagerFactoryclass =org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean> 
< property name =jpaVendorAdapter> 
< bean class =org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter/> 
< / property> 
< property name =persistenceXmlLocationvalue =classpath *：META-INF / test-persistence.xml/> 
< property name =persistenceUnitNamevalue =testingDatabase/> 
< property name =dataSourceref =dataSource/> 
< / bean> 
 
< bean id =sharedEntityManagerclass =org.springframework.orm.jpa.support.SharedEntityManagerBean> 
< property name =entityManagerFactoryref =entityManagerFactory/> 
< / bean> 
 
< bean id =transactionManagerclass =org.springframework.orm.jpa.JpaTransactionManager> 
< property name =entityManagerFactoryref =entityManagerFactory/> 
< / bean> 
 
< tx：annotation-driven /> 
  

我的persistence.xml文件是

 < persistence version =2.0
 xmlns =http://java.sun.com/xml/ns/persistencexmlns：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 =testingDatabasetransaction-type =RESOURCE_LOCAL> 
< provider> org.hibernate.ejb.HibernatePersistence< / provider> 
<属性> 
< property name =hibernate.ejb.cfgfilevalue =/ hsql_hibernate.cfg.xml/> 
< property name =org.hibernate.FlushModevalue =commit/> 
< / properties> 
< / persistence-unit> 
< /余辉> 
  

和我的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/>

< / session-factory>

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);
    }

    ...

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 />

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>

and my hibernate config file is

<?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>

You may need to extend

org.springframework.orm.jpa.vendor.HibernateJpaDialect
