Spring 3.1 Hibernate 4 不回滚 JDBC 事务

Question

我在设置将回滚的 JUnit 测试时遇到问题。在决定写一个问题之前，我已经在 SO 上阅读了其中的一些帖子，因为似乎没有一个能解决我的问题。

第二个测试用例失败，因为数据从第一个测试用例插入并保存在数据库中。

这是 JUnit 测试:

package com.company.group.spring.dao;

import static org.junit.Assert.assertNotNull;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import org.springframework.transaction.annotation.Transactional;

import com.company.group.spring.model.BusObj;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:NAME_OF_CONFIG_FILE.xml"})
@Transactional
@TransactionConfiguration(transactionManager = "txManager", defaultRollback = true)
@TestExecutionListeners({TransactionalTestExecutionListener.class,
    DependencyInjectionTestExecutionListener.class}) 
public class PerPartsWCDAOTest {

    @Autowired
    @Qualifier("myBusObjDAO")
    private BusObjDAO busObj_dao;

    @Transactional
    @Test
    public void testInsertRollback() {
        try {
        BusObj busObj = new BusObj("some data...");

        assertNotNull(busObj_dao);
        assertNotNull(busObj);

        busObj_dao.insert(perPartWC);
        }
        catch (NullPointerException e) {
            e.printStackTrace();
        }
    }

    @Transactional
    @Rollback(false)
    @Test
    public void testInsert() {
        BusObj busObj2 = new BusObj("some data...");

        busObj_dao.insert(perPartWC2);
    }

}

这是 DAOImpl 类(我要测试的类):

package com.company.group.spring.dao;

import javax.sql.DataSource;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.namedparam.BeanPropertySqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.jdbc.core.namedparam.SqlParameterSource;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.company.group.spring.model.BusObj;

@Repository("myBusObjDAO")
public class myBusObjDAOImpl implements myBusObjDAO {

private NamedParameterJdbcTemplate jdbcTemplate;

@Autowired
public void setDataSource(DataSource dataSource) {
    this.jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}

@Override
public void insert(BusObj someObj) {
    String sql = "insert into TABLE (args...) " +
            "VALUES (:named_params....)";

    SqlParameterSource paramSource = new BeanPropertySqlParameterSource(someObj);

    jdbcTemplate.update(sql, paramSource);
}

部分相关配置:

  <tx:annotation-driven transaction-manager="txManager" proxy-target-class="true" />


  <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
      <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
      <property name="url" value="jdbc:oracle:thin:@SERVER:PORT:DB"/>
      <property name="username" value="USER"/>
      <property name="password" value="XXXXXX"/>

  </bean>

更新: 我在日志中注意到，它正在尝试回滚 Hibernate 事务(但这是 JDBC)。然后注意到“txManager”的类当前是 org.springframework.orm.hibernate4.HibernateTransactionManager，所以我尝试了 org.springframework.jdbc.datasource.DataSourceTransactionManager 和 瞧，回滚成功了。所以我认为我的问题更具体地说是我如何配置以使用 Hibernate 和 JDBC...我仍然不知道哪里出了问题。

Answer 1

您的 JUnit 和 DAO 类看起来不错。

问题可能是连接在事务回滚之前自动提交。您能否更改数据源 bean 以包含 defaultAutoCommit 属性

<bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
      <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
      <property name="url" value="jdbc:oracle:thin:@SERVER:PORT:DB"/>
      <property name="username" value="USER"/>
      <property name="password" value="XXXXXX"/>
      <property name="defaultAutoCommit" value="false" /> 
</bean> 

如果这不起作用，您可以粘贴您的控制台日志吗。
