sql建表

show databases ;
create database if not exists springstudy character set utf8;
use springstudy;
create table `User` (
                        `uid` int primary key ,
                        `username` varchar(20) not null ,
                        `password` varchar(20) not null ,
                        `status` char(1),
                        `code` varchar(50),
                        constraint check_status check ( status='Y'or 'N')
);
show tables ;
desc User;
alter table User modify uid int auto_increment;
alter table User modify uid int auto_increment;
alter table User modify username varchar(20) unique not null ;

alter table User add `date` DATETIME;
alter table User add `email` varchar(25);

表格结构

Field	Type	Null	Key	Default	Extra
uid	int(11)	NO	PRI	NULL	auto_increment
username	varchar(20)	NO	UNI	NULL
password	varchar(20)	NO		NULL
status	char(1)	YES		NULL
code	varchar(50)	YES		NULL
date	datetime	YES		NULL
email	varchar(25)	YES		NULL

druid连接池配置 （druid.properties）

jdbc.url=jdbc:mysql://106.14.162.154:3306/springstudy?characterEncoding=utf-8&useUnicode=true
jdbc.name=root
jdbc.password=密码是常规密码
jdbc.initialSize=5
jdbc.minIdle=5
jdbc.maxActive=10
jdbc.maxWait=10000
#配置间隔多久启动一次DestroyThread，对连接池内的连接才进行一次检测，单位是毫秒
#检测时:1.如果连接空闲并且超过minIdle以外的连接，如果空闲时间超过minEvictableIdleTimeMillis设置的值则直接物理关闭。
#     2.在minIdle以内的不处理。
jbbc.timeBetweenEvictionRunsMillis=600000
#配置一个连接在池中最大空闲时间，单位是毫秒
jdbc.minEvictableIdleTimeMillis=300000
#用来检测连接是否有效的sql，要求是一个查询语句，常用select 'x'。如果validationQuery为null，testOnBorrow、testOnReturn、testWhileIdle都不会起作用。
#mysql select 1
#oracle select 1 from dual
jdbc.validationQuery=select 1
#建议配置为true，不影响性能，并且保证安全性。申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效。
jdbc.testWhileIdle=true

aop中的propagation的7种配置的意思

https://my.oschina.net/wangyongzhi/blog/631200

下面是Spring中Propagation类的事务属性详解：
REQUIRED：支持当前事务，如果当前没有事务，就新建一个事务。这是最常见的选择。
SUPPORTS：支持当前事务，如果当前没有事务，就以非事务方式执行。
MANDATORY：支持当前事务，如果当前没有事务，就抛出异常。
REQUIRES_NEW：新建事务，如果当前存在事务，把当前事务挂起。
NOT_SUPPORTED：以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。
NEVER：以非事务方式执行，如果当前存在事务，则抛出异常。
NESTED：支持当前事务，如果当前事务存在，则执行一个嵌套事务，如果当前没有事务，就新建一个事务。

spring mvc路径匹配原则

静态资源和controller重名

静态资源的名字和controller的路径名字相同，需要特殊配置让其走tomcat默认的servlet

比如说有个静态资源叫hello.html 有个controller的路径是/hello。那么访问localhost/hello.html的时候会自动跳转到localhost/hello。为了避免这种现像，需要在web.xml里面定义

  <servlet-mapping>
    <servlet-name>defaultservlet-name>
    <url-pattern>/login.htmlurl-pattern>
    <url-pattern>/regist.htmlurl-pattern>

阿里云服务器25端口的问题
