使用自定义登录页面的Spring Boot LDAP身份验证未通过身份验证

Question

嗨，我正在尝试在Spring Boot应用程序中使用基于LDAP的身份验证（Spring Security）。

使用默认的登录页面时，我可以进行身份​​验证。

使用自定义登录页面时，我将重定向到同一登录页面。我在项目中没有看到任何异常或错误。

我的应用程序中包含以下代码。

WebSecurityConfig.java

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

            http.authorizeRequests()
            .antMatchers("/resources/**", "/assets/**").permitAll()
            .anyRequest().fullyAuthenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .permitAll()
            .usernameParameter("username")
            .passwordParameter("password")
            .successForwardUrl("/home");
        }

        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {

            if (Boolean.parseBoolean(ldapEnabled)) {
                auth.ldapAuthentication().contextSource().url(ldapUrls + ldapBaseDn).managerDn(ldapSecurityPrincipal)
                        .managerPassword(ldapPrincipalPassword).and().userDnPatterns(ldapUserDnPattern);
            } else {
                auth.inMemoryAuthentication().withUser("user").password("password").roles("USER").and().withUser("admin")
                        .password("admin").roles("ADMIN");
            }
        }

                required autofocus value="${sessionScope.username}">

             </div>
          </div>
       </div>
    </form>

LoginController.java

    @Controller

        @Autowired
        LoginService service;


        @GetMapping("/")

                return "error";
            }

        public String showLoginPage(ModelMap model){
            return "login";
        }
