SSH实现一个简单的权限控制实例(一)

2016-08-11 10:33 531 查看
首先,需要创建数据表,先建一个用户表User,和一个菜单表 Menu.还有用户所属角色,用来批量控制用户权限.

CREATE TABLE `tb_menu` (
`menu_id` int(10) NOT NULL AUTO_INCREMENT,
`menu_name` varchar(20) DEFAULT NULL,
`menu_url` varchar(100) DEFAULT NULL,
`parent_id` int(10) DEFAULT NULL,
PRIMARY KEY (`menu_id`)
) ENGINE=InnoDB AUTO_INCREMENT=21 DEFAULT CHARSET=utf8;

CREATE TABLE `tb_role` (
`role_id` int(10) NOT NULL AUTO_INCREMENT,
`role_name` varchar(20) DEFAULT NULL,
`rights` varchar(100) DEFAULT NULL,
PRIMARY KEY (`role_id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

CREATE TABLE `tb_user` (
`user_id` int(10) NOT NULL AUTO_INCREMENT,
`loginname` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL,
`username` varchar(20) DEFAULT NULL,
`rights` varchar(100) DEFAULT NULL,
`status` tinyint(1) DEFAULT NULL,
`role_id` int(10) DEFAULT NULL,
`last_login` datetime DEFAULT NULL,
PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8;

在webRoot下编写一个index.jsp页面:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
</head>

<body>
<script type="text/javascript">
document.location = "jsp/login.jsp";
</script>
<%-- <jsp:forward page="index.action"/> --%>
</body>
</html>

导入ssh需要的jar包,配置好环境:

web.xml:

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">

<struts>

<constant name="struts.i18n.encoding" value="utf-8"></constant>
<constant name="struts.action.extension" value="html"></constant>

<package name="auth" extends="struts-default" namespace="/auth">
<action name="index" class="indexAction">
<result>/jsp/login.jsp</result>
</action>
</package>
</struts>

以上,环境就已经配置好,struts中的index.action用来访问登录页面使用.

编写struts的IndexAction类:

import org.springframework.stereotype.Component;

import com.opensymphony.xwork2.ActionSupport;

@Component
public class IndexAction extends ActionSupport{
public String execute() {
return SUCCESS;
}
}

然后,启动服务就可以在浏览器访问了:
