篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spring-boot-2.0.3不一样系列之shiro - 搭建篇相关的知识,希望对你有一定的参考价值。

前言

       上一篇:spring-boot-2.0.3源码篇 - 国际化,讲了如何实现国际化,实际上我工作用的模版引擎是freemaker,而不是thymeleaf,不过原理都是相通的。

       接着上一篇,这一篇我来讲讲spring-boot如何整合工作中用到的一个非常重要的功能:安全,而本文的主角就是一个安全框架:shiro。

       Apache Shiro是Java的一个安全框架。目前,使用Apache Shiro的人也越来越多,因为它相当简单,对比Spring Security,可能没有Spring Security的功能强大,但是在实际工作时可能并不需要那么复杂的东西,所以使用小而简单的Shiro就足够了。对于它俩到底哪个好,这个不必纠结,能更简单的解决项目问题就好了。

摘自开涛兄的《跟我学Shiro》

       本文旨在整合spring-boot与shiro,实现简单的认证功能,shiro的更多使用细节大家可以去阅读《更我学shiro》或者看官方文档

  本文项目地址:spring-boot-shiro

spring-boot整合shiro

       集成mybatis

    Shiro不会去维护用户、维护权限;这些需要我们自己去设计/提供,然后通过相应的接口注入给Shiro;既然用户、权限这些信息需要我们自己设计、维护,那么可想而知需要进行数据库表的设计了(具体表结构看后文),既然涉及到数据库的操作,那么我们就先整合mybatis,实现数据库的操作。

     测试用例顺利通过,则表示mybatis集成成功

       开启logback日志

    其实上面的pom配置已经引入了日志依赖,如图:

    但是你会发现,spring-boot-starter-logging引入了3种类型的日志,你用其中任何一种都能正常打印日志;但是我们需要用3种吗?根本用不到,我们只要用一种即可,至于选用那种,全凭大家自己的喜欢;我了,比较喜欢logback(接触的项目中用的比较多,说白了就是这3种中最熟悉的把);我们来改下pom.xml,重新配置日志依赖:
