Spring 3 Spring Secrity 3 配置安全数据库

1、配置

<?xml version="1.0" encoding="UTF-8"?>

<b:beans xmlns="http://www.springframework.org/schema/security"

xmlns:b="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.4.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

<global-method-security pre-post-annotations="enabled">

</global-method-security>

<intercept-url pattern="/**/*" access="permitAll" />

<form-login login-page="/user/login.page" default-target-url="/index.page" authentication-failure-url="/user/login.page?login_error=1"/>

<http-basic/>

<remember-me />

</http>

<b:bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.Md5PasswordEncoder"></b:bean>

<authentication-manager>

<authentication-provider>

<password-encoder ref="passwordEncoder" >

<salt-source user-property="username" />

</password-encoder>

<jdbc-user-service data-source-ref="oracleDataSource"/>

</authentication-provider>

</authentication-manager>

</b:beans>

2、数据库Schema

create table users(      username varchar_ignorecase(50) not null primary key,      password varchar_ignorecase(50) not null,      enabled boolean not null);  create table authorities (      username varchar_ignorecase(50) not null,      authority varchar_ignorecase(50) not null,      constraint fk_authorities_users foreign key(username) references users(username));      create unique index ix_auth_username on authorities (username,authority);

3、使用

3.1用户注册

//密码进行编码保存

password = passwordEncoder.encodePassword(password, username);

Vector<GrantedAuthority> authList = new Vector<GrantedAuthority>();

//一定要加Authority，不然登陆不了

authList.add(new GrantedAuthorityImpl("ROLE_USERS"));

User user = new User(username, password, true, true, true, true, authList);

userDetailsManager.createUser(user);

return "redirect:" + referer;

3.2登陆页面

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<%@ taglib prefix='c' uri='http://java.sun.com/jstl/core_rt' %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Insert title here</title>

</head>

<body>

<c:if test="${not empty param.login_error}">

Your login attempt was not successful, try again.<br/><br/>

Reason: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}"/>.

</font>

</c:if>

<form name="f" action="<c:url value='/j_spring_security_check'/>" method="POST">

<table>

<tr><td>Password:</td><td><input type='password' name='j_password'></td></tr>

<tr><td><input type="checkbox" name="_spring_security_remember_me"></td><td>Don't ask for my password for two weeks</td></tr>

</table>

</form>

</body>

</html>

3.3应用

<sec:authorize access="hasRole('ROLE_USERS')"><a href="#fast_pub">发表文章</a> <a href="./content/editcatalog.page">管理分类</a> <a href="<c:url value="/j_spring_security_logout"/>">注销</a> </sec:authorize>

上面代码写在jsp页面里面，意思是拥有ROLE_USERS角色的用户才能访问
