本文在上1篇博文的基础上，将使用数据库中的用户进行身份认证。从本文中你将会看到Spring Security使用数据库中的用户进行身份认证仍然是非常简单的事情。
1. 在pom.xml中添加mysql数据库驱动与c3p0数据源的相干的依赖。
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
<dependency>
<groupId>c3p0</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.1.2</version>
</dependency>
2. 准备MySQL数据库及相干数据。
本例子使用到user（用户表）、role（角色表）和user_role（用户角色表）3个表，表之间的关系以下：
为了方便大家进行测试，建表的语句以下：
/*
Navicat MySQL Data Transfer
Source Server : 10.0.0.12
Source Server Version : 50619
Source Host : 10.0.0.12:3305
Source Database : favsecurity
Target Server Type : MYSQL
Target Server Version : 50619
File Encoding : 65001
Date: 2015-01⑵3 10:28:39
*/
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for role
-- ----------------------------
DROP TABLE IF EXISTS `role`;
CREATE TABLE `role` (
`id` int(11) NOT NULL DEFAULT '0' COMMENT 'id',
`name` varchar(50) DEFAULT NULL COMMENT 'name',
`descn` varchar(50) DEFAULT NULL COMMENT 'descn',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='角色表';
-- ----------------------------
-- Records of role
-- ----------------------------
INSERT INTO `role` VALUES ('1', 'ROLE_ADMIN', '管理员角色');
INSERT INTO `role` VALUES ('2', 'ROLE_USER', '用户角色');
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL DEFAULT '0' COMMENT 'id',
`username` varchar(50) DEFAULT NULL COMMENT 'username',
`password` varchar(50) DEFAULT NULL COMMENT 'password',
`status` varchar(1024) DEFAULT NULL COMMENT 'status',
`descn` varchar(1024) DEFAULT NULL COMMENT 'descd',
PRIMARY KEY (`id`),
KEY `AK_Key_1` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户表';
-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', 'admin', 'admin', '1', '管理
员');
INSERT INTO `user` VALUES ('2', 'user', 'user', '1', '用户
');
INSERT INTO `user` VALUES ('3', 'favccxx', 'favboy', '1', '帅锅');
-- ----------------------------
-- Table structure for user_role
-- ----------------------------
DROP TABLE IF EXISTS `user_role`;
CREATE TABLE `user_role` (
`user_id` int(11) DEFAULT NULL COMMENT '用户表_id',
`role_id` int(11) DEFAULT NULL COMMENT '角色表_id',
KEY `FK_FK_USER_ROLE_ROLE` (`role_id`),
KEY `FK_FK_USER_ROLE_USER` (`user_id`),
CONSTRAINT `FK_FK_USER_ROLE_USER` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`),
CONSTRAINT `FK_FK_USER_ROLE_ROLE` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户角色表';
-- ----------------------------
-- Records of user_role
-- ----------------------------
INSERT INTO `user_role` VALUES ('1', '1');
INSERT INTO `user_role` VALUES ('1', '2');
INSERT INTO `user_role` VALUES ('2', '2');
INSERT INTO `user_role` VALUES ('3', '1');
INSERT INTO `user_role` VALUES ('3', '2');
3. 修改springSecurity.xml，更改security:authentication-provider提供的用户访问机制。
|
<security:authentication-manager>
<security:authentication-provider>
<security:user-service>
<security:user name="favccxx" password="favccxx" authorities="ROLE_USER,ROLE_ADMIN"/>
<security:user name="super" password="super" authorities="ROLE_SUPERADMIN"/>
</security:user-service>
</security:authentication-provider>
</security:authentication-manager>
|
将上面的灰色划掉的部份更改成下面绿色的部份。
|
<security:authentication-manager>
<security:authentication-provider>
<security:jdbc-user-service data-source-ref="dataSource" users-by-username-query="select username,password,1 as enabled from user WHERE username=?"
authorities-by-username-query="select u.username, r.name as role from user u,user_role ur, role r where u.id=ur.user_Id and r.id = ur.role_Id and u.username=?"/>
</security:authentication-provider>
</security:authentication-manager>
|
备注：dataSource在springdb.xml中定义，在springSecurity.xml中援用springdb.xml便可。springdb.xml相干的文件以下：
<?xml version="1.0" encoding="UTF⑻"?>
