java - 如何从 Controller 中的多个 View 中选择一个 View (我不想要 if/else 因为我可能有很多 View )

Question

if ( accountType = "admin" )
        return admin view
if ( accountType = "customer" )
        return customer view
if ( accountType = "user" )
        return user view
if ( accountType = "merketing" )
        return marketing view

等等......

Answer 1

使用 map ，通过给定的键注册您的 View :

viewsMap.put("admin", admin_view);
viewsMap.put("customer", customer_view);
...

然后，只需执行:

View view = viewsMap.get(accountType);
if (view == null) {
    return error_view;
}
return view;
