组织。springframework。刀。HibernateTemplate中的InvalidDataAccessApiUsageException

Question

我使用hibernate-4.1.2和spring-framework-4.1.6中的所有jar文件来尝试hibernateTemplate问题中指定的项目。我正面临一个组织。springframework。刀。InvalidDataAccessApiUsageException

上面提到的错误堆栈建议将会话的刷新模式设置为COMMIT/AUTO或从事务定义中删除“readOnly”标记。有没有办法通过spring依赖注入或hibernate注释来实现这些功能？？

Answer 1

解决方法：使用com。springsource。组织。aopalliance-1.0.0。jar和@Transactional注释问题可以解决。

启用事务：可以通过配置文件启用事务注释：

test.xml

<?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:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

    <!-- Creating TransactionManager Bean-->
    <bean id="tm"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="bds" />
    </bean>

    <!-- Creating DataSource Bean-->
    <bean id="bds" class="org.apache.tomcat.dbcp.dbcp.BasicDataSource">

        <property name="username" value="system"/>
        <property name="password" value="manager"/>
        <property name="maxActive" value="15"/>
        <property name="maxIdle" value="5"/>
        <property name="maxWait" value="5000"/>
    </bean> 

    <!-- Creating SessionFactory Bean-->
    <bean id="sf" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="bds" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
        <property name="annotatedClasses">
            <list>
                <value>model.Student</value>
            </list>
        </property>
    </bean>

    <bean id="ht" class="org.springframework.orm.hibernate4.HibernateTemplate">
        <property name="sessionFactory" ref="sf" />
    </bean>

    <bean id="dao" class="dao.StudentDaoImplHT">
        <property name="ht" ref="ht" />
    </bean>

</beans>

已启用的批注可用于导入组织。springframework。交易注释。对指定的java类进行事务处理。通过@Transactional（readOnly=false），注释readOnly标记被设置为false，事务可以很容易地提交到表中。

package dao;

import java.util.List;

import org.hibernate.criterion.DetachedCriteria;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.transaction.annotation.Transactional;
import model.Student;

public class StudentDaoImplHT implements StudentDaoInterface {

    private HibernateTemplate ht;

    public void setHt(HibernateTemplate ht) {
        this.ht = ht;
    }

    @Override
    @Transactional(readOnly = false)
    public int save(Student st) {

        int i=(Integer)ht.save(st);
        return i;
    }

                    .
                    .
                    .
                    .

}

你能试试getHibernateTemplate（）吗。getSessionFactory（）。getCurrentSession‌​().设置FlushMode（Flus‌​hMode。自动）或将其添加到应用程序上下文中。xml
