>我一直在尝试使用Thymeleaf的安全标签，但我无法让它们工作。 这是我的安全类：
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private Environment env;
@Autowired
private UserSecurityService userSecurityService;
private BCryptPasswordEncoder passwordEncoder() {
return SecurityUtility.passwordEncoder();
}
private static final String[] PUBLIC_MATCHERS = { "/css/**", "/js/**", "/image/**", "/", "/myAccount" };
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().
antMatchers(PUBLIC_MATCHERS).permitAll().anyRequest().authenticated();
http.csrf().disable().cors().disable().formLogin().failureUrl("/login?error").defaultSuccessUrl("/")
.loginPage("/login").permitAll().and().logout()
.logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/?logout")
.deleteCookies("remember-me").permitAll().and().rememberMe();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userSecurityService).passwordEncoder(passwordEncoder());
}
}

我的问题是名为"我的帐户"的两个导航项都显示在页面上，我猜标签 sec：authorize 没有得到识别或类似的东西，或者我显然做错了什么：( 我需要做任何其他配置吗？我正在使用 spring boot 2，我尝试以不同的方式解决这个问题，从更改 thymeleaf-extras-springsecurity4 的版本到在 spring 上下文中添加一个 bean，但它仍然不起作用：(
在 Spring 引导自动配置中，不会自动配置SpringSecurityDialect的实例。因此，您有这个问题。尝试添加如下所示的SpringSecurityDialect豆，我希望它会起作用。
@Bean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
