1、项目结构
2、关于spring容器用到的配置文件内容如下
<?xml version="1.0" encoding="UTF-8"?>

<bean id="newsDao" class="my.study.spring.dao.impl.NewsDaoImpl">

</bean>
</beans>
3、测试代码的核心部分如下<插入两条数据；第一条正确；第二条title为空违反了数据表不为空的约束>
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
NewsDao nd = (NewsDao)ctx.getBean("newsDao");
News n = new News();
n.setId(UUID.randomUUID().toString());
n.setTitle("ok43");
n.setContent("今天很和平");
nd.create(n);
News n2 = new News();
n2.setId(UUID.randomUUID().toString());
//n2.setTitle("");
n2.setContent("今天很和平");
nd.create(n2);
4、控制台输出结果为:<底层数据库插入了第一条数据；第二条数据违反约束所以未插入。>
Caused by: java.sql.BatchUpdateException: Column 'title' cannot be null

5、我的问题：
按理说因为增加了Spring事务特性，两条插入的代码也处在同一个事务当中；第二条发生了异常应该一起回滚才对，不应该插入一条数据？各位大侠，请赐教。
------解决思路----------------------
两个事务 事务加在dao上了
------解决思路----------------------
你的事务加在DAO上了，每次插入操作都是一个事务
