import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

    @RequestMapping("/toAddUser")

        request.setAttribute("user", user);
        
        return "/userManager";
    }
}

Answer 1

没发userDao啊

在getAllUser方法上加Transactional注解

如果没有事务，刚开始的线程上下文是拿不到session的
