測試spring + myBaits + H2數據庫回滾不起作用

Question

我現在有測試用例和數據庫H2（我使用myBatis）時遇到問題。 我需要回滾。 我配置了Spring上下文：

<?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:jee="http://www.springframework.org/schema/jee" xmlns:jdbc="http://www.springframework.org/schema/jdbc"

    xsi:schemaLocation="  
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd  
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd     
    http://www.springframework.org/schema/jdbc
    http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
    http://www.springframework.org/schema/jee
    http://www.springframework.org/schema/jee/spring-jee.xsd
    ">

    <context:annotation-config />

    <context:component-scan base-package="com.miweb.prueba.core" />


<jdbc:embedded-database id="dataSource" type="H2">
    <jdbc:script location="classpath:schemas.sql" />
    <jdbc:script location="classpath:data.sql" />
</jdbc:embedded-database>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
        <property name="mapperInterface"
            value="com.miweb.prueba.core.dao.mybatis.SentenciasSqlMybatisMapper" />
        <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    </bean>

</beans>

我的Junit測試是：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-configuration-test/applicationContextTest.xml")
public class DispDaoTest {

    @Autowired
    public DispositivoDao mDispDao;

@Test
public void testDelete() {  
    long cant = mDispDao.delete(1);

    assertTrue(cant >= 0);
}

@Test
public void tesUpdate() {
    Dispositivo disp = mDispDao.searchById(1);

    disp.setAge(24);

    long cant = mDispDao.update(disp);

    Dispositivo dipsBuscado = mDispDao.searchById(1);
    assertNotNull(dipsBuscado);

    assertTrue(cant >= 0);
    assertTrue(cantidadActualizados >= 0);
        assertTrue(24== dipsBuscado.getAge() );
    }
}

但是，我嘗試使用注釋，但它不起作用：

@Transactional
@TransactionConfiguration(defaultRollback = true)

使用@Transacional，每個測試都會失敗。 錯誤：

我也嘗試在每個測試中使用@Rollback（true），但是什么也沒有發生（如果先彈出刪除測試，然后更新測試失敗）。

這個錯誤告訴我Spring找不到“ transactionManager”。 我不直接使用transactionManager，而是使用H2數據庫。

如何為每個測試獨立進行回滾？

Answer 1

嘗試將這些行添加到XML配置中

<tx:annotation-driven transaction-manager="transactionManager"/>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
</bean>

然后重新引入@Transactional批注
