Spring Security3简单应用(权限设备在数据库中)
添加时间:2013-5-14 点击量:
1、权限设备在数据库中,典范的五张表。
1)t_user 用户表
2)t_role 角色表
3)t_user_role 用户-角色接洽关系表
4)t_resource 资料表
5)t_role_resource 角色-资料接洽关系表
2、建表语句
DROP TABLE IF EXISTS `t_resource`;
CREATE TABLE `t_resource` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`name` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
`url` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
PRIMARY KEY (`id`)
)
DROP TABLE IF EXISTS `t_role`;
CREATE TABLE `t_role` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`name` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
PRIMARY KEY (`id`)
)
DROP TABLE IF EXISTS `t_role_resource`;
CREATE TABLE `t_role_resource` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`role_id` int(11) NULL DEFAULT NULL ,
`resource_id` int(11) NULL DEFAULT NULL ,
PRIMARY KEY (`id`)
)
CREATE TABLE `t_user` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`account` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
`password` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
PRIMARY KEY (`id`)
)
DROP TABLE IF EXISTS `t_user_role`;
CREATE TABLE `t_user_role` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`user_id` int(11) NULL DEFAULT NULL ,
`role_id` int(11) NULL DEFAULT NULL ,
PRIMARY KEY (`id`)
)
3、对应的范畴实体
1)用户
package cn.luxh.app.domain;
/
用户
@author Luxh
/
public class User {
private Integer id;
/帐号/
private String account;
/暗码/
private String password;
@Override
public int hashCode() {
return account.hashCode();
}
@Override
public boolean equals(Object obj) {
User user = (User) obj;
return this.account.equals(user.getAccount());
}
//getter setter
//... }
2)角色
package cn.luxh.app.domain;
/
角色
@author Luxh
/
public class Role {
private Integer id;
/角色名称/
private String name;
//getter setter
//...
}
3)用户-角色
package cn.luxh.app.domain;
/
用户角色
@author Luxh
/
public class UserRole {
private Integer id;
/用户id/
private Integer userId;
/角色id/
private Integer roleId;
//getter setter
//...
}
4)资料
package cn.luxh.app.domain;
/
资料
@author Luxh
/
public class Resource {
private Integer id;
/资料名称/
private String name;
/接见地址/
private String url;
//getter setter
}
5)角色-资料
package cn.luxh.app.domain;
/
角色资料
@author Luxh
/
public class RoleResource {
private Integer id;
/角色id/
private Integer roleId;
/资料id/
private Integer resourceId;
//getter setter
}
4、设备文件
在web.xml文件中加上如下内容:
<!-- SpringSecurity权限框架 -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>
org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
<!-- 获取Spring Security session的生命周期-->
<listener>
<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>
</listener>
当然设备spring器的时辰得把springsecurity的权限设备文件给加载进去:
<!-- 设备Spring器 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml,classpath:application-security.xml</param-value>
</context-param>
权限设备文件内容如下:

6、此中资料表内容如下
7、源码,含数据库文件和初始化值
http://files.cnblogs.com/luxh/app4.rar
8、在页面上的把握权限
1)引入标签: <%@ taglib prefix=sec uri=http://www.springframework.org/security/tags %>
2)应用标签:如下,审核操纵时具有ROLE_ADM权限才可以看到。
<sec:authorize ifAnyGranted=ROLE_ADM>
<li><a href=javascript:auditPage(¥{ctx}/task/auditPage?taskId=¥{task.taskId})>审核</a></li>
</sec:authorize>
1、权限设备在数据库中,典范的五张表。
1)t_user 用户表
2)t_role 角色表
3)t_user_role 用户-角色接洽关系表
4)t_resource 资料表
5)t_role_resource 角色-资料接洽关系表
2、建表语句
DROP TABLE IF EXISTS `t_resource`;
CREATE TABLE `t_resource` (
`id` int(11) NOT NULL AUTO_INCREMENT ,
`name` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,

7、源码,含数据库文件和初始化值
http://files.cnblogs.com/luxh/app4.rar
8、在页面上的把握权限
1)引入标签: <%@ taglib prefix=sec uri=http://www.springframework.org/security/tags %>
2)应用标签:如下,审核操纵时具有ROLE_ADM权限才可以看到。
<sec:authorize ifAnyGranted=ROLE_ADM>
<li><a href=javascript:auditPage(¥{ctx}/task/auditPage?taskId=¥{task.taskId})>审核</a></li>
</sec:authorize>
