我在整合thymeleaf的时候遇到一些坑，想拿出来分享一下
首先我使用的是springboot最新版本：2.1.1 一下是pom.xml文件：
<?xml version="1.0" encoding="UTF-8"?>

配置类：
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
/**
* 认证请求规则
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("VIP1")
.antMatchers("/level2/**").hasRole("VIP2")
.antMatchers("/level3/**").hasRole("VIP3");
// 会/login到 登录页面
http.formLogin();
http.logout().logoutSuccessUrl("/");
}
/**
* 授权
* @param auth
* @throws Exception
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().passwordEncoder(new passwordEncoder())
.withUser("zhangsan").password("123456").roles("VIP1","VIP2")
.and()
.withUser("lisi").password("123456").roles("VIP2","VIP3")
.and()
.withUser("wangwu").password("123456").roles("VIP1","VIP3");
}
}
页面：
<html xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
<div sec:authorize="!isAuthenticated()">
<h2 align="center">游客您好，如果想查看 <a th:href="@{/login}">请登录</a></h2>
</div>
<div sec:authorize="isAuthenticated()">
<h2><span sec:authentication="name"></span>，您好,您的角色有：
<span sec:authentication="principal.authorities"></span></h2>
<form th:action="@{/logout}" method="post">
<input type="submit" value="注销"/>
</form>
</div>
遇到的问题：
1、页面的认证授权标签无效：
请注意版本问题：
thymeleaf-extras-springsecurity5 适配的版本为 security 5.x.x
2、 登录报错：
password id 为 null
解决：
写一个工具类：
public class passwordEncoder implements PasswordEncoder {
@Override
public String encode(CharSequence charSequence) {
return charSequence.toString();
}
@Override
public boolean matches(CharSequence charSequence, String s) {
return s.equals(charSequence.toString());
}
}
配置passwordEncoder即可
