# 用来检测连接是否有效的sql,要求是一个查询语句
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL
# 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。
spring.datasource.druid.test-while-idle=true
# 申请连接时执行validationQuery检测连接是否有效,做了这个配置会降低性能。
spring.datasource.druid.test-on-borrow=false
# 归还连接时执行validationQuery检测连接是否有效,做了这个配置会降低性能。
spring.datasource.druid.test-on-return=false
# 是否缓存preparedStatement,也就是PSCache。PSCache对支持游标的数据库性能提升巨大,比如说oracle。在mysql下建议关闭。

前42行是对druid的基础配置,包括基础数据源配置,以及druid的基础参数;
47~50行是mybatis中对于mapper的xml的配置,便于项目启动后扫描到xml的相关文件,xml内写的是项目相关的sql。
45行指默认项目启动默认端口为8000。
52行~60行是thymeleaf的基础配置,thymeleaf是一种常见的模板引擎,相当于jsp这样的前台代码。
为了实现简单的登录功能,我们在controller中定义一些接口方法:

搭配前台的代码一起分析:

在项目启动后,访问http://localhost:8000/login,进入到登录页面,首先加载必要的css和js资源,在填写好用户名、密码后,点击登录,会执行user_login的接口方法, 简单的对用户进行校验,即可进入首页。
其次要说的是这个项目中,添加了验证码的功能,使用了kaptcha的依赖。在登录界面中,增加了验证码的显示,点击验证码图片后,可以切换验证码。
登录界面
