Question

我目前遇到问题，包括测试用例和数据库H2（我使用myBatis）。我需要做一个回滚。我配置了我的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测试是：

@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，我尝试使用注释，但它不起作用：

@Transactional
@TransactionConfiguration(defaultRollback = true)

使用@Transacional，每个测试都会失败。错误：

此外，我在每个测试中尝试使用@Rollback（true），但没有任何反应（如果首先弹出删除测试，则更新测试失败）。

这个错误告诉我Spring找不到“transactionManager”。我不直接使用transactionManager，我使用H2数据库。

我如何独立完成每个测试的回滚？

Answer 1

尝试将这些行添加到XML配置

<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注释

测试弹簧+ myBaits + H2数据库回滚不起作用
