JUint 单元测试-事务回滚

在 Sring 中进行单元测试，如果不想改变数据库结构，则需要事物回滚来保持数据库的数据完整。

## 1. 在 xml 配置文件中设置事物 ##

<?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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        
        <tx:annotation-driven transaction-manager="transactionManager"/>
    
        
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>
    
        <bean id="dataSource" name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
            
            <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
            
            <property name="url" value="jdbc:mysql://127.0.0.1:3306/mydb/>  <property name="username" value="xxx"/>
            
            <property name="password" value="xxx"/>
            <property name="useUnfairLock" value="true"/>
            
            <property name="testOnBorrow" value="true"/>
            <property name="testOnReturn" value="false"/>
            
            <property name="testWhileIdle" value="true"/>
            <property name="validationQuery" value="select 1 "/>
        </bean>
    
    </beans>

## 2.在单元测试类中增加事务注解 ##

@TransactionConfiguration(transactionManager = "transactionManager")
    @Transactional()

`@TransactionConfiguration` 默认都是回滚事务的，也就是说默认 `Rollback=true`

等同于：

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
    @Transactional()

在测试方法上使用 `@Rollback(true)` 或 `@Rollback(false)` 可对单独的方法进行回滚或不回滚控制。

示例

@RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = {
            "classpath:test-spring-mybatis.xml",
            "classpath:test-service-application.xml",
            "classpath:test-application-cache.xml",
            "classpath:test-sinocare-event.xml"
    })
    @TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
    @Transactional()
    public class CustomerTagServiceTest { 
    
        @Autowired
        private CustomerTagService customerTagService;
    
        @Test
        public void testList(){
            List<CustomerTagVo> customerTagVoList = customerTagService.list().getData();
            Assert.assertNotNull(customerTagVoList);
        }
    
        @Test
        @Transactional
        @Rollback(true)
        public void testAdd(){
            CustomerTagVo tagVo = new CustomerTagVo();
            tagVo.setName("极品客户");
            Boolean result = customerTagService.add(tagVo).getData();
            Assert.assertTrue(result);
        }
    }
