response.write(session.getAttribute("BranchName")提示错误!
The method write(Object) is undefined for the type HttpServletResponse
[解决办法]
改成这样吧
response.write((String)session.getAttribute("BranchName"))
[解决办法]
response.write 的参数 有 long int char[] String
session.getAttribute取出来的都是Object
需要根据你实际的类型转换到上面几种类型
