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

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

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"/><!-- 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。
secureResourceFilterInvocationDefinitionSource实现

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
