spring security实现方式大致可以分为这几种：
1.配置文件实现，只需要在配置文件中指定拦截的url所需要权限、配置userDetailsService指定用户名、密码、对应权限，就可以实现。
2.实现UserDetailsService，loadUserByUsername(String userName)方法，根据userName来实现自己的业务逻辑返回UserDetails的实现类，需要自定义User类实现UserDetails，比较重要的方法是getAuthorities()，用来返回该用户所拥有的权限。
3.通过自定义filter重写spring security拦截器，实现动态过滤用户权限。
4.通过自定义filter重写spring security拦截器，实现自定义参数来检验用户，并且过滤权限。
1.最简单配置spring-security.xml，实现1

2.实现UserDetailsService
先整理下spring secruity验证流程：
springSecurity的登录验证是由org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter这个过滤器来完成的,在该类的父类AbstractAuthenticationProcessingFilter中有一个AuthenticationManager接口属性,验证工作主要是通过这个AuthenticationManager接口的实例来完成的。在默认情况下，springSecurity框架会把org.springframework.security.authentication.ProviderManager类的实例注入到该属性
UsernamePasswordAuthenticationFilter的验证过程如下：
1. 首先过滤器会调用自身的attemptAuthentication方法，从request中取出authentication, authentication是在org.springframework.security.web.context.SecurityContextPersistenceFilter过滤器中通过捕获用户提交的登录表单中的内容生成的一个org.springframework.security.core.Authentication接口实例.
2. 拿到authentication对象后，过滤器会调用ProviderManager类的authenticate方法，并传入该对象
3.ProviderManager类的authenticate方法中会调用类中的List<AuthenticationProvider> providers集合中的各个AuthenticationProvider接口实现类中的authenticate(Authentication authentication)方法进行验证，由此可见，真正的验证逻辑是由各个AuthenticationProvider接口实现类来完成的。DaoAuthenticationProvider类是默认情况下注入的一个AuthenticationProvider接口实现类
4.provider的实现类在验证用户时，会调用userDetailsService的实现类的loadUserByUsername方法来获取用户信息，
首先spring-security配置文件

3.实现动态过滤用户权限
在spring-security配置文件的http标签中添加如下配置
<custom-filter before="FILTER_SECURITY_INTERCEPTOR" ref="securityInterceptor"/>
在spring-security配置文件中添加如下配置
<!-- 自定义拦截器 --> <beans:bean id="securityInterceptor" class="com.ultrapower.me.util.security.interceptor.SecurityInterceptor"> <beans:property name="authenticationManager" ref="authenticationManager"/> <beans:property name="accessDecisionManager" ref="mesecurityAccessDecisionManager"/> <beans:property name="securityMetadataSource" ref="secureResourceFilterInvocationDefinitionSource" /> </beans:bean> <!-- 获取访问url对应的所有权限 --> <beans:bean id="secureResourceFilterInvocationDefinitionSource" class="com.ultrapower.me.util.security.interceptor.SecureResourceFilterInvocationDefinitionSource" /> <!-- 校验用户的权限是否足够 --> <beans:bean id="mesecurityAccessDecisionManager" class="com.ultrapower.me.util.security.interceptor.SecurityAccessDecisionManager" />
securityInterceptor继承AbstractSecurityInterceptor过滤器，实现Filter过滤器
package com.ultrapower.me.util.security.interceptor;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import org.springframework.security.access.SecurityMetadataSource;
import org.springframework.security.access.intercept.AbstractSecurityInterceptor;
import org.springframework.security.access.intercept.InterceptorStatusToken;
import org.springframework.security.web.FilterInvocation;
import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;
public class SecurityInterceptor extends AbstractSecurityInterceptor implements Filter{
//配置文件注入
private FilterInvocationSecurityMetadataSource securityMetadataSource;
public FilterInvocationSecurityMetadataSource getSecurityMetadataSource() {
return securityMetadataSource;
}
public void setSecurityMetadataSource(
FilterInvocationSecurityMetadataSource securityMetadataSource) {
this.securityMetadataSource = securityMetadataSource;
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub\
FilterInvocation fi = new FilterInvocation(request, response, chain);
//fi里面有一个被拦截的url
//里面调用MyInvocationSecurityMetadataSource的getAttributes(Object object)这个方法获取fi对应的所有权限
//再调用MyAccessDecisionManager的decide方法来校验用户的权限是否足够
InterceptorStatusToken token = super.beforeInvocation(fi);
try {
//执行下一个拦截器
fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
} finally {
super.afterInvocation(token, null);
}
}
@Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
@Override
public Class<?> getSecureObjectClass() {
// TODO Auto-generated method stub
return FilterInvocation.class;
}
@Override
public SecurityMetadataSource obtainSecurityMetadataSource() {
// TODO Auto-generated method stub
return this.securityMetadataSource;
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
}
登陆后，每次访问资源都会被这个拦截器拦截，会执行doFilter这个方法，这个方法调用了invoke方法，其中fi断点显示是一个url（可能重写了toString方法吧，但是里面还有一些方法的），最重要的是beforeInvocation这个方法，它首先会调用MyInvocationSecurityMetadataSource类的getAttributes方法获取被拦截url所需的权限，在调用MyAccessDecisionManager类decide方法判断用户是否够权限。弄完这一切就会执行下一个拦截器。

mesecurityAccessDecisionManager实现

*/
@Override
public void decide(Authentication authentication, Object object,

throws AccessDeniedException, InsufficientAuthenticationException {
// 对应url没有权限时，直接跳出方法
if(configAttributes == null){
return;
}
Iterator<ConfigAttribute> ite=configAttributes.iterator();
//判断用户所拥有的权限，是否符合对应的Url权限，如果实现了UserDetailsService，则用户权限是loadUserByUsername返回用户所对应的权限
while(ite.hasNext()){
ConfigAttribute ca=ite.next();
String needRole=((SecurityConfig)ca).getAttribute();
for(GrantedAuthority ga : authentication.getAuthorities()){
System.out.println(":::::::::::::"+ga.getAuthority());
if(needRole.equals(ga.getAuthority())){
return;
}
}
}
//注意：执行这里，后台是会抛异常的，但是界面会跳转到所配的access-denied-page页面
throw new AccessDeniedException("no right");
}
@Override
public boolean supports(ConfigAttribute attribute) {
return true;
}
@Override
public boolean supports(Class<?> clazz) {
return true;
}
}
4.实现AuthenticationProvider，自定义参数验证
这种验证以前项目用过，现在没有写示例代码，先写下大概流程和需要用到的类
这种验证的好处：可以在自定义登录界面添加登录时需要的参数，如多个验证码等、可以修改默认登录名称和密码的参数名
整体流程：
1.用户登录时，先经过自定义的passcard_filter过滤器，该过滤器继承了AbstractAuthenticationProcessingFilter，并且绑定了登录失败和成功时需要的处理器(跳转页面使用)
2.执行attemptAuthentication方法，可以通过request获取登录页面传递的参数，实现自己的逻辑，并且把对应参数set到AbstractAuthenticationToken的实现类中
3.验证逻辑走完后，调用 this.getAuthenticationManager().authenticate(token);方法，执行AuthenticationProvider的实现类的supports方法
4.如果返回true则继续执行authenticate方法
5.在authenticate方法中，首先可以根据用户名获取到用户信息，再者可以拿自定义参数和用户信息做逻辑验证，如密码的验证
6.自定义验证通过以后，获取用户权限set到User中，用于springSecurity做权限验证
7.this.getAuthenticationManager().authenticate(token)方法执行完后，会返回Authentication，如果不为空，则说明验证通过
8.验证通过后，可实现自定义逻辑操作，如记录cookie信息
9.attemptAuthentication方法执行完成后，由springSecuriy来进行对应权限验证，成功于否会跳转到相对应处理器设置的界面。
1.自定义PassCardAuthenticationToken类，继承AbstractAuthenticationToken类，用于定义参数，需要实现的方法
/**
* 凭证，用户密码
*/
@Override
public Object getCredentials() {
return password;
}
/**
* 当事人，登录名 用户Id
*/
@Override
public Object getPrincipal() {
return userID;
}
2.User类要实现Authentication，需要实现的方法
/**
* 返回用户所属权限
*/
@Override
public Collection<GrantedAuthority> getAuthorities() {
return this.accesses;
}
@Override
public Object getCredentials() {
return null;
}
@Override
public Object getDetails() {
return null;
}
/**
* 登录名称
*/
@Override
public Object getPrincipal() {
return loginName;
}
/**
* 是否认证
*/
@Override
public boolean isAuthenticated() {
return this.authenticated;
}
/**
* 设置是否认证字段
*/
@Override
public void setAuthenticated(boolean isAuthenticated)
throws IllegalArgumentException {
this.authenticated=isAuthenticated;
}
3.需要userService实现AuthenticationProvider的 authenticate(Authentication authentication)方法
@SuppressWarnings("unchecked")
@Override
public Authentication authenticate(Authentication authentication)
throws AuthenticationException {
PassCardAuthenticationToken token=(PassCardAuthenticationToken)authentication;
/*
* 这里进行逻辑认证操作，可以获取token中的属性来自定义验证逻辑，代码验证逻辑可以不用管
* 如果使用UserDetailsService的实现类来验证，就只能获取userName，不够灵活
*/
if(token.getUserID()!=null&&token.getPassword()!=null){
User user=(User)this.getDao().executeQueryUnique("User.loadByLoginName", QueryCmdType.QUERY_NAME, token.getUserID());
String password=token.getPassword();
if(this.passwordEncoder!=null){
password=this.passwordEncoder.encodePassword(password, null);
}
if(!password.equalsIgnoreCase(user.getPassword())){
token.setErrCode("2");
return null;
}
if( token.isEnablePasscard() && usePassCard ){//token中激活密码卡且系统使用密码卡
int position1=((token.getRow1()-1)*7)+token.getColumn1();
int position2=((token.getRow2()-1)*7)+token.getColumn2();
//System.out.println( "---pos:"+position1+"---"+position2 );
if(user.getPassCardId()==null){
token.setErrCode("10");
return null;
}
PassCard passcard=this.passCardDao.findById(user.getPassCardId(), false);
if(passcard==null||passcard.getStatus()==PassCardHelper.STATUS_CANCEL ){
token.setErrCode("10");
return null;
}
if(passcard.getConfusedContent()==null || passcard.getConfusedContent().length()<7*7*32 ){
token.setErrCode("10");
return null;
}
String content=passcard.getConfusedContent();
int perLen=content.length()/49;
String str1=content.substring((position1-1)*perLen, position1*perLen);
String str2=content.substring((position2-1)*perLen, position2*perLen);
String inputStr1=token.getCard1();
String inputStr2=token.getCard2();
if(this.passwordEncoder!=null){
inputStr1 = md5.getMD5ofStr(md5.getMD5ofStr(inputStr1));
inputStr2 = md5.getMD5ofStr(md5.getMD5ofStr(inputStr2));
}
if((!str1.equalsIgnoreCase(inputStr1))||(!str2.equalsIgnoreCase(inputStr2))){
token.setErrCode("10");
return null;
}
}
user.setLastIp(token.getIp());
user.setLastLogin(new Date());
this.getDao().saveOrUpdate(user);
user.setAuthenticated(true);
/*
* 导入一次角色权限，并且把权限set到User中，用于spring验证用户权限(getAuthorities方法)
*/
List<UserRole> userRoles=(List<UserRole>)this.getDao().executeQueryList("UserRole.listRoleByUserID", QueryCmdType.QUERY_NAME, -1, -1, user.getId());
Set<GrantedAuthority> accesses=new HashSet<GrantedAuthority>();
for(UserRole ur:userRoles){
accesses.add(ur.getRole());
}
user.getOrg().getOrgName();
if(user.getOrg().getCertTypes()!=null) user.getOrg().getCertTypes().size();//延迟载入一下
user.setAccesses(accesses);
return user;
}
return null;
}
重写supports(Class<? extends Object> authentication)方法，authentication要
/**
* 如果此处验证不通过，是不会执行authentication方法的
*/
@Override
public boolean supports(Class<? extends Object> authentication) {
return authentication.equals(PassCardAuthenticationToken.class);
}
4.定义filter，实现AbstractAuthenticationProcessingFilter的attemptAuthentication方法，用于获取在登录页面传递过来的参数，spring默认只获取userName(j_username)，password(j_username)，而且实现UserDetailsService时只传递username

s.setAttribute("__login_error", token.getErrCode());
} else {
s.removeAttribute("__login_error");
s.removeAttribute("__login_username");
s.removeAttribute("__cert_userid");
if( token.isEnablePasscard()) {
s.removeAttribute("__passcard_row1");
s.removeAttribute("__passcard_row2");
s.removeAttribute("__passcard_column1");
s.removeAttribute("__passcard_column2");
}
}
} catch (AuthenticationException e) {
s.setAttribute("__login_error", token.getErrCode());
throw e;
}
return auth;
}
public void setSuccessPage(String successPage) {
this.successPage = successPage;
}
public void setFailurePage(String failurePage) {
this.failurePage = failurePage;
}
public void setForward(boolean forward) {
this.forward = forward;
}
public void setCertLoginUrl(String certLoginUrl) {
this.certLoginUrl = certLoginUrl;
}
@Override
public void afterPropertiesSet() {
super.afterPropertiesSet();
/*
*该处理器实现了AuthenticationSuccessHandler, AuthenticationFailureHandler
*用于处理登录成功或者失败后，跳转的界面
*/
AuthenticationResultHandler handler = new AuthenticationResultHandler();
handler.setForward(forward);
handler.setLoginFailurePage(failurePage);
handler.setLoginSuccessPage(successPage);
handler.setCertLoginUrl(certLoginUrl);
//设置父类中的处理器
this.setAuthenticationSuccessHandler(handler);
this.setAuthenticationFailureHandler(handler);
}
}
最后为spring-security配置文件中的配置，需要添加authentication-provider的引用，和filter的配置
<security:authentication-manager alias="authenticationManager">
<!-- 注意，这里仅仅是系统默认的认证机制，请在正式系统中明确知道其功能再使用 -->
<security:authentication-provider ref="acocunt_defaultAnthentiactionProvider"/>
<security:authentication-provider ref="registrationService"/>
<security:authentication-provider ref="enrollmentService"/>
<security:authentication-provider ref="userService"/>
</security:authentication-manager>
<bean id="passcard_filter" class="cn.edu.jszg.cert.security.PasscardAuthenticationProcessingFilter">
<property name="authenticationManager" ref="authenticationManager"/>
<property name="useVerifyCode" value="true"/>
<property name="failurePage" value="/portal/home/auth/"></property>
<property name="config" ref="webAppConfig"/>
<property name="userLogService" ref="userLogService" />
<property name="certLoginUrl" value="${cert.login.url}"/>
</bean>
还要在http中添加<security:custom-filter ref="passcard_filter" after="SECURITY_CONTEXT_FILTER"/>
