首页 > 解决方案 > Spring Security + Thymeleaf - 如果未通过身份验证,则对用户隐藏特定数据

问题描述

我认为 Thymeleaf 不知道用户何时登录,我已经向经过身份验证<a>的用户隐藏了两个标签,但它们仍然显示。

pom.xml:

    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity4</artifactId>
        <version>3.0.4.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>

这是问题的代码 - 对经过身份验证的用户隐藏两个锚标记:

<html lang="en" xmlns:th="http://www.thymeleaf.org"
                xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
...
...

<div sec:authorize="isAnonymous()">
    <a th:href="@{/login}">Log in</a>
    <br>
    <a th:href="@{/register}">Register</a>
</div>

<br>

<a th:href="@{/recipeList}">List Page</a>

即使在我登录后,我仍然看到“登录”和“注册”标签

这是配置,如果它有用的话:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public DataSource dataSource;

    @Bean
    PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public JdbcUserDetailsManager jdbcUserDetailsManager() throws Exception{
        JdbcUserDetailsManager jdbcUserDetailsManager = new JdbcUserDetailsManager();
        jdbcUserDetailsManager.setDataSource(dataSource);
        return jdbcUserDetailsManager;
    }

    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception{
        auth.jdbcAuthentication().dataSource(dataSource).passwordEncoder(passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                    .antMatchers("/", "/home").permitAll()
                    .antMatchers("/register").permitAll()
                    .antMatchers("/recipeList").permitAll()
                    .antMatchers("/foodDescription/**").permitAll()
                    .antMatchers("/addNew/**").hasAnyRole("ADMIN","USER")
                    .antMatchers("/delete/**").hasRole("ADMIN")
                    .antMatchers("/edit/**").hasRole("ADMIN")
                    .anyRequest().authenticated()
                    .and()
                .formLogin()
                    .defaultSuccessUrl("/")
                    .permitAll()
                    .and()
                .logout()
                    .logoutSuccessUrl("/").permitAll();
        http.csrf().disable();
    }
}

我的猜测是 Thymeleaf 不知道用户何时登录,如果我的代码需要任何其他类,我将对其进行编辑。现在一直被困在这上面。

解决方案


我假设您使用的是 Spring Boot 2.1.x

然后你必须使用版本 5:

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