本文介绍了一个基于Spring框架的事务集成测试方案。通过配置数据源、事务管理器等组件，搭建了支持事务回滚的测试环境。并通过扩展Spring的抽象事务测试类，实现了自动配置和清理测试数据的功能。

基于Spring事务的集成测试

一、测试类和配置文件的目录结构

test

bbs.spring.common.test

BaseTransactionalIntegrationTests

applicationContext.xml

bbs.spring.service.test

TopicServiceImplTest

applicationContext-test.xml

二、applicationContext.xml配置

配置数据源、事务和依赖注入，暴露带事务的业务接口。

......

<!-- hibernateTemplate ..................................................... -->

    <bean id="hibernateTemplate"

        class="org.springframework.orm.hibernate3.HibernateTemplate">

        <property name="sessionFactory" ref="sessionFactory" />

    </bean>

    

 

    <!-- transactionManager .................................................... -->

    <bean id="transactionManager"

        class="org.springframework.orm.hibernate3.HibernateTransactionManager">

        <property name="sessionFactory">

            <ref local="sessionFactory" />

        </property>

    </bean>

 

 

    <!-- 事务代理工厂bean模板 ................................................. -->

    <bean id="baseTransactionProxy" abstract="true"

        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">

        <property name="transactionManager" ref="transactionManager" />

        <property name="proxyTargetClass" value="true" />

        <property name="transactionAttributes">

            <props>

                <prop key="*">PROPAGATION_REQUIRED</prop>

            </props>

        </property>

    </bean>

 

 

    <!-- 实例化Dao .............................................................. -->

    <bean id="topicDao"

        class="org.eesite.bbs.hibernate.dao.TopicDaoImpl">

        <property name="sessionFactory" ref="sessionFactory" />

    </bean>

 

 

    <!-- Transactional proxy for the Application primary business object ..... -->

    <bean id="topicServiceTarget"

        class="org.eesite.bbs.spring.service.TopicServiceImpl">

        <property name="topicDao" ref="topicDao" />

    </bean>

 

 

    <!-- TransactionProxyFactoryBean ........................................... -->

    <bean id="topicService" parent="baseTransactionProxy">

        <description />

        <property name="proxyInterfaces">

            <list>

                <value>

                    org.eesite.bbs.spring.service.ITopicService

                </value>

            </list>

        </property>

        <property name="target">

            <ref bean="topicServiceTarget" />

        </property>

    </bean>

三、扩展Spring抽象事务测试类

package bbs.spring.common.test;

 

import org.springframework.orm.hibernate3.HibernateTemplate;

import org.springframework.test.AbstractTransactionalDataSourceSpringContextTests;

 

/**

 * 扩展Spring抽象事务测试类, 注入hibernateTemplate, 实现getConfigLocations方法

 * 

 * @author zhanjia

 * 

 */

public abstract class BaseTransactionalIntegrationTests extends

        AbstractTransactionalDataSourceSpringContextTests {

 

    private HibernateTemplate hibernateTemplate;

 

    /**

     * @return the hibernateTemplate

     */

    public HibernateTemplate getHibernateTemplate() {

        return hibernateTemplate;

    }

 

    /**

     * @param hibernateTemplate

     *            the hibernateTemplate to set

     */

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {

        this.hibernateTemplate = hibernateTemplate;

    }

 

    /*

     * (non-Javadoc)

     * 

     * @see org.springframework.test.AbstractDependencyInjectionSpringContextTests#getConfigLocations()

     */

    @Override

    protected String[] getConfigLocations() {

        setAutowireMode(AUTOWIRE_BY_NAME);

        return new String[] {

                "classpath:bbs/spring/common/test/applicationContext.xml",

                "classpath:bbs/spring/service/test/applicationContext-test.xml" };

    }

 

}

四、applicationContext-test.xml配置

为测试类注入业务接口和hibernateTemplate.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

 

<beans>

    <bean id="topicServiceImplTest"

        class="bbs.spring.service.test.TopicServiceImplTest">

        <property name="topicService" ref="topicService" />

        <property name="hibernateTemplate" ref="hibernateTemplate" />

    </bean>

</beans>

五、测试类

package bbs.spring.service.test;

 

import java.util.List;

 

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.eesite.bbs.hibernate.vo.Sort;

import org.eesite.bbs.hibernate.vo.Topic;

import org.eesite.bbs.hibernate.vo.User;

import org.eesite.bbs.spring.service.ITopicService;

 

import bbs.spring.common.test.BaseTransactionalIntegrationTests;

 

/**

 * 主题测试类

 * 

 * @author zhanjia

 * 

 */

public class TopicServiceImplTest extends BaseTransactionalIntegrationTests {

 

    private static final Log log = LogFactory

            .getLog(TopicServiceImplTest.class);

 

    private ITopicService topicService;

 

    /**

     * @return the topicService

     */

    public ITopicService getTopicService() {

        return topicService;

    }

 

    /**

     * @param topicService

     *            the topicService to set

     */

    public void setTopicService(ITopicService topicService) {

        this.topicService = topicService;

    }

 

    public void testInsertTopic() {

        this.deleteFromTables(new String[] { "Topic", "Sort", "User" });

        // this.jdbcTemplate.execute("INSERT INTO ...");

 

        Sort sort = new Sort();

        sort.setId(new Long(1));

        sort.setSortName("分类1");

        sort.setDescription("");

 

        User user = new User();

        user.setId(new Long(1));

        user.setUserName("zhanjia");

 

        Topic topic = new Topic();

        topic.setId(new Long(1));

        topic.setTopicName("标题名");

        topic.setContent("");

        topic.setIcon("");

        topic.setSort(sort);

        topic.setUser(user);

 

        this.getTopicService().insertTopic(topic);

        

        List list = this.getHibernateTemplate().find("from Topic");

        assertEquals(1, list.size());

        

        Long count = this.jdbcTemplate.queryForLong("select count(*) from Topic");

        assertEquals(1, count.intValue());

    }

}
