如何获取struts2的源代码

通常情况下，你可以先到官方网站（域名前无“www”）下载软件包，建议下载 all 版。

以struts-2.1.6为例，你要下载struts-2.1.6-all.zip版本。

下载后解压缩。

在解压缩后的文件夹中找到lib文件夹，其下即可以找到你提及的几个jar包。

求c语言编一个多级菜单源码 2级即可 急用

#include<stdio.h> void menuFst(){ printf("***欢迎进入系统"); printf("请选择0-1进入菜单 ") ; printf("输入0退出菜单系统 "); printf("输入1进入第二级菜单 "); printf("*** "); return ; } void menuSec(){ printf("***现在是第二级菜单"); printf("请选择0-1进入菜单 ") ; printf("输入0返回上一级菜单系统 "); printf("输入1进入系统 "); printf("*** ") ; int enter ; scanf("%d",&enter) ; switch(enter){ case 0: menuFst(); break ; case 1: printf("hello"); return ; } } int main(){ //printf("%d",2836%99); menuFst() ; int enter ; scanf("%d",&enter) ; switch(enter){ case 0: printf("退出系统 ") ; break ; case 1: printf("进入下一级菜单"); menuSec() ; } return 0 ; }
