Servlet获取Init-Param

Question

如何检索这两个配置初始参数名称“Regular”和“Premier”

final String PREMIER = getServletContext().getInitParameter("Premier");
final String REGULAR = getServletContext().getInitParameter("Regular");

我试过这段代码，它给了我一个空值

self.tableView.beginUpdates()
 self.tableView.reloadRows(at: [indexPath], with: UITableViewRowAnimation.fade)
let selectedCell = tableView.cellForRow(at: indexPath) 
selectedCell.height = yourHeight
self.tableView.endUpdates()

请帮助

替换

final String PREMIER = getServletContext().getInitParameter("Premier");
final String REGULAR = getServletContext().getInitParameter("Regular");

与

final String PREMIER = getServletConfig().getInitParameter("Premier");
final String REGULAR = getServletConfig().getInitParameter("Regular");

你必须阅读servlet config init params，而不是servlet context init params。
