这个小应用描述的比较粗糙。由于刚接触。知识面也不广。基本上代码都能读懂，然后也里面的内容都懂。。
在我运行发布这个web应用时，遇到了一个问题。就是，Tomcat OutOfMemoryError:PermGen space 。大概意思就是说内存溢出了吧

return message;

public Stuinfo info(){
Stuinfo info=new Stuinfo();
info.setId(this.getId());
info.setName(this.getName());
info.setSex(this.getSex());

public void message(String mess){
int type=JOptionPane.YES_NO_OPTION;
String title="提示信息";
JOptionPane.showMessageDialog(null, mess, title, type);

}
这样我们发布在本地的Tomcat上，就可以访问页面了。
