一个很简单的Spring JDBC 编程式事务的简单实现，代码逻辑较简单，希望有可能帮助初学的同学。本例使用mysql8.0，在db3数据库下有个student表，内含两个属性，id与name。

                jdbcTemplate.execute("insert into students values(2,\"zhangsan\");");
                //id为primary key，不能重复，否则会报错，事务回滚，也就是这个人不能加入数据库
                transactionManager.commit(status);
            }
            catch(Exception e){
                transactionManager.rollback(status);
