        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.thymeleaf</groupId>
            <artifactId>thymeleaf-spring5</artifactId>
        </dependency>
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-java8time</artifactId>
        </dependency>

2.编写静态页面

3.编写工具类测试

package com.kun.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class RouterController {

    @RequestMapping({"/","index"})
    public String index(){
        return "index";
    }
    @RequestMapping("/toLogin")
    public String toLogin(){
        return "views/login";
    }
    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id") int id){
        return "views/level1/"+id;
    }
    @RequestMapping("/level2/{id}")
    public String level2(@PathVariable("id") int id){
        return "views/level2/"+id;
    }
    @RequestMapping("/level3/{id}")
    public String level3(@PathVariable("id") int id){
        return "views/level3/"+id;
    }
}

4.编写自定义config @EnableWebSecurity

1.继承WebSecurityConfigurerAdapter

实现权限访问

@Override
    protected void configure(HttpSecurity http) throws Exception {
//        首页所有人访问
        http.authorizeHttpRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");
//      没有权限跳到登录页面   开启登录页面
        http.formLogin();
//        防止网站工具
        http.csrf().disable();
//        注销功能
        http.logout().logoutSuccessUrl("/");
    }

实现角色认证

//    认证
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("daiyu").password(new BCryptPasswordEncoder().encode("123")).roles("vip1","vip2","vip3")
                .and()
                .withUser("root").password(new BCryptPasswordEncoder().encode("123")).roles("vip1")
                .and()
                .withUser("admin").password(new BCryptPasswordEncoder().encode("123")).roles("vip3");

    }

5.应有界面的显示与隐藏

1.导入依赖

        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity5</artifactId>
            <version>3.0.4.RELEASE</version>
        </dependency>

2.导入命名空间（有提示）

xmlns:sec="http://www.thymeleaf.org/extras/spring-security"

 <!--未登录-->
<div sec:authorize="!isAuthenticated()">
   <a class="item" th:href="@{/toLogin}">
       <i class="address card icon"></i> 登录
   </a>
</div>
<!--  注销-->
<div sec:authorize="isAuthenticated()">
    <a class="item">
        用户名：<span sec:authentication="name"></span>
<!-- 还有就是这个改一下sec:authentication="principal.authorities"-->
         角色：<span sec:authentication="principal.authorities"></span>
    </a>
</div>
<div sec:authorize="isAuthenticated()">
    <a class="item" th:href="@{/logout}">
         <i class="sign-out icon"></i> 注销
    </a>
</div>

<div class="column" sec:authorize="hasRole('vip1')">

6.开启记住我功能

        http.rememberMe();

7.重命名

        http.formLogin().loginPage("/toLogin")   //登录界面
   //当后台数据名字和前端的名字不匹配：这样改
                .usernameParameter("username").passwordParameter("password")
                .loginProcessingUrl("/login");   //命名完，可以直接在页面写这个名字

http.rememberMe().rememberMeParameter("remember");
//让按钮的name属性等于                    它

二、shiro

hello shiro

1.导入依赖

<dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>

shiro整合spring

1.导入依赖

<!--        shiro - spring-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.1</version>
        </dependency>

2.创建一个类继承AuthorizingRealm

public class UserRealm extends AuthorizingRealm {
//    授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("授权");
        return null;
    }
//认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("认证");
        return null;
    }
}

3.测试

        bean.setFilterChainDefinitionMap(map);

        bean.setLoginUrl("/toLogin");

        return bean;
    }
//    2
    @Bean(name = "a")
    public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){

    }
}

shiro认证

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //        获取当前用户
        Subject subject= SecurityUtils.getSubject();
//        封装用户的登录数据
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        try {
            subject.login(token);
            return "index";
        }catch (UnknownAccountException e){
            model.addAttribute("msg","用户名错误");
            return "login";
        }catch (IncorrectCredentialsException i){
            model.addAttribute("msg","密码错误");
            return "login";
        }
    }

//认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("认证");
//        用户户名 密码
        String name="root";
        String password="123";
        UsernamePasswordToken userToken= (UsernamePasswordToken) token;
        if(!userToken.getUsername().equals(name)){
            return null;  //抛出异常
        }
//        密码认证

        return new SimpleAuthenticationInfo("",password,"");
    }

shiro错误三：

java.lang.NoClassDefFoundError: org/apache/log4j/Level架包冲突，删除相应的架包即可

错误四：

import org.apache.shiro.ini.IniSecurityManagerFactory出错；

报Cannot resolve symbol ‘ini‘等错误；

过时问题：

        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
        securityManager.setRealm(iniRealm);
 

        SecurityUtils.setSecurityManager(securityManager);

需求：
