  确实需要注意加上引号，谢谢各位提醒：

  this.setUsername(this.getInitParameter("username"));

  this.setPassword(this.getInitParameter("password"));

  public void init() throws ServletException {

  super.init();//需要加上这条语句就好啦

  this.setUsername(this.getInitParameter("username"));

  this.setPassword(this.getInitParameter("password"));

  }

  public void init() throws ServletException {

  this.setUsername(this.getInitParameter("username"));

  this.setPassword(this.getInitParameter("password"));

  是不是username和password没有加双引号啊
