怎么在SpringBoot2中對Shiro進行配置？針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
基礎環境：依賴
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring-boot-starter</artifactId> <version>1.4.0</version> </dependency>
如果不是前后端分離，要實現頁面級的權限控制，則加入以下依賴就可以使用shiro的權限標簽了（記得在html頭部加上相應約束：
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="Thymeleaf" xmlns:shiro="http://www.pollix.at/thymeleaf/shiro" lang="en"> ）： <dependency> <groupId>com.github.theborakompanioni</groupId> <artifactId>thymeleaf-extras-shiro</artifactId> <version>2.0.0</version> </dependency>

}補充：SpringBoot配置Shiro時踩坑
在SpringBoot2.0整合shiro時使用@EnableAutoConfiguration的時候需要對config文件進行掃描，即使用@ComponentScan對配置進行掃描。
或者直接使用@SpringBootApplication,但是這種方法會將主方法目錄下的所有package都進行掃描影響項目效率。
Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - zxc, rememberMe=false]. Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException
當出現此異常時，一般情況是用戶名密碼不匹配，或者是在配置對應的Realm時出現空值導致匹配失敗。
