Question

我正在使用webapp，春天的安全 Spring框架。春天webflow。我想从相同的登录页面验证两个不同类型的用户，即user1和user2。两者在数据库中都有不同的表，并为它们定义了不同的实体类我正在使用jsf .xhtml页面登录我的登录页面。我使用了primefaces gui并在tab的帮助下为user1和user2提供了登录页面。这是我的webflow定义文件。

问题是我想从id为“welcome”的相同视图状态获取user1和user2的值但我不知道如何接受他们的凭证，因为我只允许1个模型，因为我指定了model =“student”

Answer 1

你应该做的是分开学生＆＃34;和＆＃34;导师＆＃34;每个进入自己的流（文件），如果有任何重复的逻辑使用流继承，并将重复的逻辑放在一个抽象的流程中，新的＆＃34;学生＆＃34;和＆＃34;导师＆＃34;流量扩大。
