单次注销在 keycloak 和 spring security 中不起作用

Question

我正在使用 keycloak 服务器及其 spring 安全适配器来保护两个示例应用程序。一切正常，除了没有开箱即用的单一注销解决方案。有什么具体的配置吗？

这是我的注销按钮：

    <c:url var="logoutUrl" value="/sso/logout"/>
    <form class="form-inline" action="${logoutUrl}" method="post">
        <input type="submit" value="Log out" />
        <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
    </form>   

这是我的 spring-security 配置文件：

Answer 1

您可以使用 Spring 的注销模式，其余的由 Spring Security 负责。这是一个例子：

    <form method="post" action="logout">
            <input class="logout-input" type="submit" value="Log Out"></> 
            <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
    </form>
