访问Spring Security'；s FormLoginBeanDefinitionParser'；AuthenticationSuccessHandler实现中的s属性

我想在AuthenticationSuccessHandler实现中访问表单登录标记的配置属性

示例情况如下所示：

@Autowired
private FormLoginBeanDefinitionConfigurationProperties properties;

public class CustomAuthenticationSuccessHandler extends SimpleUrlAuthenticationFailureHandler {
   String usernameParameterName = properties.getUsernameParameter();
   String passwordParameterName = properties.getPasswordParameter();
}

当spring安全配置按如下方式配置时：

<security:form-login
            login-page="/login.html"
            username-parameter="the_username_parameter"
            password-parameter="the_password-parameter"
            login-processing-url="/dologin"
            authentication-success-handler-ref="customAuthenticationSuccessHandler"
            authentication-failure-handler-ref="customAuthenticationFailureHandler"

    />

但是类似的事情似乎不可行，因为它是通过AuthenticationConfigBuilder和FormLoginConfiguler反射配置的，并且尝试在应用程序上下文XML中显式定义它将产生另一个UsernamePasswordAuthenticationFilter，它与我所拥有的servlet上下文配置无关设定

欢迎提出任何建议和想法

@Autowired
private UsernamePassworAuthenticationFilter formAuthenticationFilter;

public class CustomAuthenticationSuccessHandler extends SimpleUrlAuthenticationFailureHandler {
    String usernameParameterName = formAuthenticationFilter.getUsernameParameter();
    String passwordParameterName = formAuthenticationFilter.getPasswordParameter();     
}
