Spring 事务问题

 

1、 在testcontext下的事务操作

步骤1：继承类：extends AbstractTransactionalJUnit4SpringContextTests   

步骤2：申明容器：@ContextConfiguration(locations = { "classpath:normandy/spring/normandy-domain-beans.xml" })

步骤3：申明事物：@TransactionConfiguration(defaultRollback = false)

步骤4：对数据源的事务配置

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

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

  默认情况下， 处于testcontext监控下的类是使用事务操作的。如果某个方法不需要事物，则需要进行显示的说明。

@Test
    @Transactional(propagation=Propagation.NOT_SUPPORTED, isolation=Isolation.DEFAULT)
    public void testPublish4Length() throws IllegalArgumentException,
            InterruptedException {
        List<ConfigValue> configValues0 = configValueUtil.getAllConfigValue();
        int versionInit0 = 0;
        for (ConfigValue configValue : configValues0) {
            ConfigKey configKey = configValue.getConfigKey();
            if (normandyKey.equals(configKey.getGlobeUid())) {
                versionInit0 = configValue.getVersion();
            }
        }
        System.out.println("==============" + versionInit0);

        try {
            simpleNormandyClient.publish(normandyKey, normandyValue);
            Thread.sleep(2000);
            // 取得version值
            List<ConfigValue> configValues1 = configValueUtil
                    .getAllConfigValue();
            int versionInit = 0;
            for (ConfigValue configValue : configValues1) {
                ConfigKey configKey = configValue.getConfigKey();
                if (normandyKey.equals(configKey.getGlobeUid())) {
                    versionInit = configValue.getVersion();
                }
            }
            System.out.println("==============" + versionInit);

            simpleNormandyClient.publish(normandyKey, normandyValue);
            Thread.sleep(2000);
            List<ConfigValue> configValues2 = configValueUtil
                    .getAllConfigValue();

            int versionLast = 0;
            // 取得version值，version=version+1
            for (ConfigValue configValue : configValues2) {
                ConfigKey configKey = configValue.getConfigKey();
                if (normandyKey.equals(configKey.getGlobeUid())) {
                    versionLast = configValue.getVersion();
                }
            }
            System.out.println("==============" + versionLast);

            assertEquals(versionInit + 1, versionLast);
        } catch (IllegalArgumentException e) {
            throw new IllegalArgumentException("version检查出错");
        }
    }

测试结果：

【注意】

1、 默认情况下，遇到运行期例外：回滚数据；非运行期例外：不回滚数据
