在 Html 页面中创建注销链接

Question

我有使用 Spring Security Basic Authentication 和 thymeleaf 的登录和注销表单。

我的问题是我的注销链接显示为按钮。但我想将它包含在<a href=""> 标记中。但是当我在<a href=""> 标签中包含我的注销链接时，它不起作用。这是我的代码。

注销控制器 - Spring Boot

@RequestMapping(value = {"/logout"}, method = RequestMethod.POST)
public String logoutDo(HttpServletRequest request,HttpServletResponse response){
HttpSession session= request.getSession(false);
    SecurityContextHolder.clearContext();
         session= request.getSession(false);
        if(session != null) {
            session.invalidate();
        }
        for(Cookie cookie : request.getCookies()) {
            cookie.setMaxAge(0);
        }

    return "redirect:/login?logout";
}

注销表单 - 前端

<form th:action="@{/logout}" method="POST">
        <input type="submit" value="Logout"/>
   </form>

安全配置

@Override
protected void configure(HttpSecurity http) throws Exception {


    http
    .requestMatchers()
    .antMatchers("/login", "/",  "/customer/**", "/registration", "/admin/**")
    .and()
    .authorizeRequests()
    .antMatchers("/admin/**").hasAuthority("ADMIN").antMatchers("/customer/**").hasAuthority("CUSTOMER")
    .antMatchers("/login", "/registration", "/").permitAll()
    .anyRequest().authenticated()
    .and()
    .httpBasic().and().csrf().disable()

    .formLogin()  //login configuration
            .loginPage("/login")
            .loginProcessingUrl("/login")
            .usernameParameter("email")
            .passwordParameter("password")
            .defaultSuccessUrl("/customer/home")    
    .and().logout()    //logout configuration
    .logoutUrl("/logout") 
    .logoutSuccessUrl("/login")
    .and().exceptionHandling() //exception handling configuration
    .accessDeniedPage("/error");

    }

解决方法是提交“隐藏​​”表单：

<a href="javascript: document.logoutForm.submit()" > Logout Link </a>

<form name="logoutForm" th:action="@{/logout}" method="post" th:hidden="true">
      <input hidden type="submit" value="Logout"/>
</form>
