@Transactional事务的简单使用
作者：互联网
@Transactional只有经过经过 Spring 的代理类才能生效，调用类中的方法，事务不会生效，@EnableTransactionManagement不加上事务也可以生效
CREATE TABLE IF NOT EXISTS telephone(
id INT PRIMARY KEY AUTO_INCREMENT COMMENT '主键',
ocm_cust_id VARCHAR(100) NOT NULL,
is_default VARCHAR(40) NOT NULL,
telephone_number VARCHAR(40) NOT NULL
)ENGINE=INNODB DEFAULT CHARSET=utf8;
SELECT * FROM telephone WHERE ocm_cust_id='ocm123456' AND is_default='Y'
INSERT INTO telephone(ocm_cust_id,is_default,telephone_number)
