spring security

依赖

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

用户认证和授权

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //所有人都能访问首页,有对应权限的人才能访问功能页
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");

        //没有权限,默认回到登陆页面
        http.formLogin();
        //开启注销,回到指定页面
        http.logout().logoutSuccessUrl("/");
        //开启记住用户
        http.rememberMe().rememberMeParameter("remember");
    }

    //认证
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("abc").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1", "vip2")
                .and()
                .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1", "vip2", "vip3");
    }
}

使用数据库认证

@Autowired
private DataSource dataSource;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    // ensure the passwords are encoded properly
    UserBuilder users = User.withDefaultPasswordEncoder();
    auth
        .jdbcAuthentication()
            .dataSource(dataSource)
            .withDefaultSchema()
            .withUser(users.username("user").password("password").roles("USER"))
            .withUser(users.username("admin").password("password").roles("USER","ADMIN"));
}

注销与权限控制

依赖

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

首页

<div class="right menu">
    <!--未登录-->
    <div sec:authorize="!isAuthenticated()">
        <a class="item" th:href="@{/toLogin}">
            <i class="address card icon"></i> 登录
        </a>
    </div>

    <!--已登录-->
    <div sec:authorize="isAuthenticated()">
        <a class="item">
            用户名: <span sec:authentication="name"></span>
            权限: <span sec:authentication="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>

按权限展示

sec:authorize="hasRole('vip1')"

记住账户和首页定制

登录页

<input type="checkbox" name="remember"> 记住我
