1、Durid
1.1 简介
Java程序很大一部分要操作数据库,为了提高性能操作数据库的时候,又不得不使用数据库连接池。
Druid 是阿里巴巴开源平台上一个数据库连接池实现,结合了 C3P0、DBCP 等 DB 池的优点,同时加入了日志监控。
Druid 可以很好的监控 DB 池连接和 SQL 的执行情况,天生就是针对监控而生的 DB 连接池。
Druid已经在阿里巴巴部署了超过600个应用,经过一年多生产环境大规模部署的严苛考验。
Spring Boot 2.0 以上默认使用 Hikari 数据源,可以说 Hikari 与 Driud 都是当前 Java Web 上最优秀的数据源,我们来重点介绍 Spring Boot 如何集成 Druid 数据源,如何实现数据库监控。

- #2、切换数据源;之前已经说过 Spring Boot 2.0 以上默认使用 com.zaxxer.hikari.HikariDataSource 数据源,但可以 通过 spring.datasource.type 指定数据源。
- # 指定数据源类型

- # 初始化时建立物理连接的个数。初始化发生在显示调用init方法,或者第一次getConnection时
- initialSize: 5

- timeBetweenEvictionRunsMillis: 60000
- # 配置一个连接在池中最小生存的时间,单位是毫秒

- # 用来检测连接是否有效的sql,要求是一个查询语句。如果validationQuery为null,testOnBorrow、testOnReturn、testWhileIdle都不会其作用。
- validationQuery: 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
- testWhileIdle: 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。
- testOnBorrow: 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
- testOnReturn: 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

- # 合并多个DruidDataSource的监控数据

2、SpringSecurity
2.0 认识SpringSecurity
Spring Security 是针对Spring项目的安全框架,也是Spring Boot底层安全模块默认的技术选型,他可以实现强大的Web安全控制,对于安全控制,我们仅需要引入 spring-boot-starter-security 模块,进行少量的配置,即可实现强大的安全管理!
记住几个类:
- WebSecurityConfigurerAdapter:自定义Security策略
- AuthenticationManagerBuilder:自定义认证策略
- @EnableWebSecurity:开启WebSecurity模式
Spring Security的两个主要目标是 “认证” 和 “授权”(访问控制)。
“认证”(Authentication)
身份验证是关于验证您的凭据,如用户名/用户ID和密码,以验证您的身份。
身份验证通常通过用户名和密码完成,有时与身份验证因素结合使用。
“授权” (Authorization)
授权发生在系统成功验证您的身份后,最终会授予您访问资源(如信息,文件,数据库,资金,位置,几乎任何内容)的完全权限。
这个概念是通用的,而不是只在Spring Security 中存在。
