3.配置spring.xml
<?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:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans                     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                     http://www.springframework.org/schema/context                     http://www.springframework.org/schema/context/spring-context-3.0.xsd                     http://www.springframework.org/schema/aop                     http://www.springframework.org/schema/aop/spring-aop-3.0.xsd                     http://www.springframework.org/schema/tx                     http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"><bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>WEB-INF/config/jdbc.properties</value><!--数据库配置存放--></list></property></bean><!-- 以下配置数据源， 使用连接池 --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName" value="${jdbc.driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource"><ref bean="dataSource" /></property><property name="hibernateProperties"><props><prop key="hibernate.dialect"> org.hibernate.dialect.OracleDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop></props></property><property name="mappingLocations"><list><value>classpath:/com/common/dm/*.hbm.xml</value></list></property></bean><bean id="usersDao" class="com.common.dao.UsersDaoImpl"><property name="sessionFactory" ref="sessionFactory"></property></bean></beans>

3.spring- security.xml配置
<?xml version="1.0" encoding="UTF-8"?><beans:beans xmlns="http://www.springframework.org/schema/security"xmlns:beans="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-3.0.xsd                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd"><global-method-security pre-post-annotations="enabled" /><http auto-config="true" access-denied-page="/403.jsp"><!--  自定义无权限页面 --><!-- 自定义登录页面，若不定义则spring自动生成 --><form-login login-page="/login.jsp" /><intercept-url pattern="/login.jsp*" access="IS_AUTHENTICATED_ANONYMOUSLY" /><!--不进行拦截  --><intercept-url pattern="/index.jsp*" access="ROLE_ADMIN,ROLE_VISIT" /><intercept-url pattern="/admin.jsp*" access="ROLE_ADMIN" /></http><authentication-manager><authentication-provider user-service-ref="myAuthenticationProvider"></authentication-provider><!-- <authentication-provider> <user-service> <user name="WJL" password="WJL" authorities="ROLE_ADMIN"/> </user-service> </authentication-provider> --></authentication-manager><beans:bean id="myAuthenticationProvider"class="com.common.security.MyhAuthenticationProvider"><beans:property name="usersDao" ref="usersDao"></beans:property></beans:bean></beans:beans>

在MyhauthenticationProvider中进行与数据库的交互;

代码如下

package com.common.security;import java.util.ArrayList;import java.util.Collection;import org.springframework.security.core.GrantedAuthority;import org.springframework.security.core.authority.GrantedAuthorityImpl;import org.springframework.security.core.userdetails.User;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.core.userdetails.UsernameNotFoundException;import com.common.dao.UsersDao;import com.common.dm.Users;/** * <p> * mailto: reven_wjl@163.com * </p> *  * @author reven * @date 2012-9-23 * @version 1.0.1 */public class MyhAuthenticationProvider implements UserDetailsService {private UsersDao usersDao;public UsersDao getUsersDao() {return usersDao;}public void setUsersDao(UsersDao usersDao) {this.usersDao = usersDao;}public UserDetails loadUserByUsername(String userName)throws UsernameNotFoundException {// TODO Auto-generated method stubCollection<GrantedAuthority> auths = new ArrayList<GrantedAuthority>();Users user = usersDao.getUserByUserName(userName);if(user != null){String password = user.getPassword();String limit = user.getLimits();if (limit.equals("1")) {GrantedAuthorityImpl auth = new GrantedAuthorityImpl("ROLE_ADMIN");auths.add(auth);}if (limit.equals("0")) {GrantedAuthorityImpl auth = new GrantedAuthorityImpl("ROLE_VISIT");auths.add(auth);}User userspring = new User(userName, password, true, true, true, true,auths);return userspring;}else{return null;}}}


与数据库交互的方法就不列举了，很简单


login.jsp格式

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><% %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>用户登录</title><script></script></head><body><h3>用户登录</h3><form action='/spring-security/j_spring_security_check' method='POST'>用户名:<input type="text" name="j_username"/>密码:<input type="password" name="j_password"/><input type="submit"><label style="color: red">${sessionScope.SPRING_SECURITY_LAST_EXCEPTION.message}</label>//错误信息</form></body></html>
