Freemarker的viewResolver与Spring有一个问题-会话属性不公开给视图，就像Spring的InternalResourceViewResolver中一样

现在，重要的部分是：当我从Spring的解析器更改为Freemarker的解析器时，会话属性并没有传递，它是空的。当Spring的解析器工作时，会话被传递

    <!-- Code for JSTL -->
    ${userSession}


${error}
${userSession}
B
${userSession}

由于重定向Attributes.addFlashAttribute（）而导致会话问题。这意味着

addFlashAttribute实际上将属性存储在flashmap中（该属性在用户会话中进行内部维护，并在满足下一个重定向请求后删除），

只需尝试不使用redirectAttributes.addFlashAttribute（）即可获得会话

也许这对你有帮助
