SpringBoot使用SpringSecurity和Shiro和swagger

SpringBoot整合SpringSecurity：https://www.bilibili.com/video/BV1KE411i7bC?p=1
SpringBoot整合Shiro框架：https://www.bilibili.com/video/BV1NE411i7S8?p=1
SpringBoot文档：http://felord.cn/_doc/_springboot/2.1.5.RELEASE/_book/
https://docs.spring.io/spring-boot/docs/current/reference/html/
系统安全框架，用于认证、授权 
1、SpringSecurity依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
<version>2.5.3</version>
</dependency>

2、命名空间xmlns:th=http://www.thymeleaf.org   xmlns:sec=http://www.thymeleaf.org/extras/spring-security   xmlns:shiro=http://www.pollix.at/thymeleaf/shiro

3、自己创建SecurityConfig

        //禁用csrf跨站
        http.csrf().disable();
        //开启登录，定制登录页，自定义请求参数名 和 登录请求地址。
        //如果不自定义登录请求地址，那登录form的action需要是loginPage指定的地址 /userLogin
        http.formLogin().loginPage("/userLogin")
                .usernameParameter("uname")

                .loginProcessingUrl("/loginHandler");
        //记住我，自定义请求参数
        http.rememberMe().rememberMeParameter("remember");
        //注销、删除cookie、清除session
        http.logout().deleteCookies("remove").invalidateHttpSession(true);

<input type="checkbox" name="remember" />Remember Me
<br/>
<button type="submit">submit</button>

 loginHandler可以处理自己其他的登录逻辑。

引入fragment：<div th:insert="~{common/head :: header}"></div>，shiro前端提示需要引入html命名空间：xmlns:shiro="http://www.pollix.at/thymeleaf/shiro"
