Spring Security 使用数据库用户进行认证

本文参考或摘录自：http://haohaoxuexi.iteye.com/blog/2157769

本文使用Spring Security自带的方式连接数据库对用户进行认证。

1、Spring Security 默认的表脚本：

/*
Navicat MySQL Data Transfer

Source Server         : localhost
Source Server Version : 50621
Source Host           : localhost:3306
Source Database       : security

Target Server Type    : MYSQL
Target Server Version : 50621
File Encoding         : 65001

Date: 2014-12-10 15:49:04
*/

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for authorities
-- ----------------------------
DROP TABLE IF EXISTS `authorities`;
CREATE TABLE `authorities` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(20) DEFAULT NULL,
  `authority` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Table structure for groups
-- ----------------------------
DROP TABLE IF EXISTS `groups`;
CREATE TABLE `groups` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `groupName` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Table structure for group_authorities
-- ----------------------------
DROP TABLE IF EXISTS `group_authorities`;
CREATE TABLE `group_authorities` (
  `group_Id` int(11) NOT NULL AUTO_INCREMENT,
  `authority` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`group_Id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Table structure for group_members
-- ----------------------------
DROP TABLE IF EXISTS `group_members`;
CREATE TABLE `group_members` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `userName` varchar(20) DEFAULT NULL,
  `group_Id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Table structure for users
-- ----------------------------
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `id` int(8) NOT NULL AUTO_INCREMENT,
  `userName` varchar(20) DEFAULT NULL,
  `password` varchar(50) DEFAULT NULL,
  `enabled` tinyint(4) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

2、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <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>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml,/WEB-INF/dispatcher-servlet.xml,/WEB-INF/spring-security.xml</param-value>
    </context-param>
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>/WEB-INF/log4j.properties</param-value>
    </context-param>
    <context-param>
        <param-name>log4jRefreshInterval</param-name>
        <param-value>60000</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

2、spring-security配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:security="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security.xsd">
    <security:http auto-config="true">
        <security:intercept-url pattern="/**" access="ROLE_USER"></security:intercept-url>
    </security:http>
    <security:authentication-manager>
        <security:authentication-provider user-service-ref="userDetailsService">
            <security:password-encoder hash="md5"></security:password-encoder>
        </security:authentication-provider>
    </security:authentication-manager>

    <bean id="userDetailsService" class="org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl">
        <property name="dataSource" ref="dataSource"/>   --指定数据源
        <property name="enableGroups" value="true"/>
    </bean>
</beans>

说明：<security:authentication-provider ref="myAuthenticationProvider"/>是指使用实现了自己的AuthenticationProvider

<security:authentication-provider user-service-ref="userDetailsService">是指定使用的UserDetailsService

3、数据源配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/security"></property>
        <property name="user" value="root"></property>
        <property name="password" value="root"></property>
        <property name="acquireIncrement" value="5"></property>  <!-- 当连接池中的连接用完时，C3P0一次性创建新连接的数目2 -->
        <property name="initialPoolSize" value="10"></property>  <!-- 初始化时创建的连接数，必须在minPoolSize和maxPoolSize之间 -->
        <property name="minPoolSize" value="5"></property>
        <property name="maxPoolSize" value="20"></property>
        <!-- 最大空闲时间，超过空闲时间的连接将被丢弃
        [需要注意：mysql默认的连接时长为8小时(28800）【可在my.ini中添加 wait_timeout=30(单位秒)设置连接超时】,这里设置c3p0的超时必须<28800]
        -->
        <property name="maxIdleTime" value="300"></property>
        <property name="idleConnectionTestPeriod" value="60"></property> <!-- 每60秒检查连接池中的空闲连接 -->
        <property name="maxStatements" value="20"></property>  <!-- jdbc的标准参数  用以控制数据源内加载的PreparedStatement数量，但由于预缓存的Statement属 于单个Connection而不是整个连接 -->
    </bean>
</beans>
