1、引入依赖和版本：
1）、properties
<properties>
<java.version>1.8</java.version>
<thymeleaf.version>3.0.9.RELEASE</thymeleaf.version>
<!-- 布局功能的支持程序 thymeleaf3主程序 layout2以上版本 -->
<!-- thymeleaf2 layout1-->
<thymeleaf-layout-dialect.version>2.2.2</thymeleaf-layout-dialect.version>
</properties>
2）、依赖
<!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity4</artifactId>
<version>3.0.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
2、配置 WebSecurityConfigurerAdapter 的相关属性：
package com.example.config;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@EnableWebSecurity
public class MySecurityConfig extends WebSecurityConfigurerAdapter{
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("VIP1")
.antMatchers("/level2/**").hasRole("VIP2")
.antMatchers("/level3/**").hasRole("VIP3");
// http.formLogin(); //当要跳转需要权限的以上资源或者"/login"时会跳转到默认登录界面
http.csrf().disable(); //将csrf关闭
http.formLogin().loginPage("/MyLogin"); //跳转到自己制定的登陆页面
http.formLogin().defaultSuccessUrl("/"); //登录成功跳转的页面
http.formLogin().failureUrl("/aaa"); //登录失败后跳转到自己制定的登陆失败页面
http.formLogin().loginProcessingUrl("/message"); //设置自定义页面form表单action路径
/*
* 1、用户注销， 清空session
* 2、注销成功会返回/login?logout 页面（默认）
*/
http.logout().logoutSuccessUrl("/");
http.rememberMe().rememberMeParameter("remember");
System.out.println("WebSecurity设置成功...");
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("huang").password("admin").roles("VIP1", "VIP2")
.and().withUser("he").password("admin").roles("VIP2", "VIP3")
.and().withUser("he2").password("admin").roles("VIP3", "VIP4");
}
}
3、自定义的登录页面：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>第一个HTML页面</title>
</head>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
自定义表单验证:
<!--<form name="f" action="/login" method="post">-->
<form name="f" action="/message" method="post">
<br/>
用户名:
<input type="text" name="username" placeholder="name"><br/>
密码:
<input type="password" name="password" placeholder="password"><br/>
<input type="checkbox" name="remember">记住我<br/>
<input name="submit" type="submit" value="提交">
</form>
</body>
</html>
4、首页（关于security的认证函数）：
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1 align="center">欢迎光临武林秘籍管理系统</h1>
<div sec:authorize="!isAuthenticated()">
<h2 align="center">游客您好，如果想查看武林秘籍 <a th:href="@{/MyLogin}">请登录</a></h2>
</div>
<div sec:authorize="isAuthenticated()">
<h2><span sec:authentication="name"></span>，您好,您的角色有：

<form th:action="@{/logout}" method="post">
<input type="submit" value="注销"/>
</form>
</div>
<hr>
<div sec:authorize="hasRole('VIP1')">

</div>
<div sec:authorize="hasRole('VIP2')">

</div>
</body>
</html>
