spring-security-3.0.3. 与Spring3.0.3 集成配置配置说明<二>

3. 实现类

3.1 加载数据库中的权限，也要实现FilterInvocationSecurityMetadataSource类

package com.bestsoft.ssh.service.impl.security;

 

/**

 * 加载所有的权限配置

 * @author zhangchaobing

 *

 */

public class InvocationSecurityMetadataSourceService implements FilterInvocationSecurityMetadataSource {  

   

      //注入自己的DAO

    @Resource(name="basicAuthoritiesHibernateDAO")

    private IBasicAuthoritiesDAO basicAuthoritiesHibernateDAO;

   

    private static Map<String, Collection<ConfigAttribute>> resourceMap = null;

    private UrlMatcher urlMatcher = new AntUrlPathMatcher();  

   

   

    /**此法方法会在启动时 被调用**/

    public  void loadResourceDefine()throws Exception  {  

        this.resourceMap = new HashMap<String, Collection<ConfigAttribute>>();  

          

        //查询数据库权限配置表

        List<BasicAuthorities> authoritiesList = basicAuthoritiesHibernateDAO.findAllByDeleteFlag();

        for(int i=0;i<authoritiesList.size();i++){  

        BasicAuthorities url = (BasicAuthorities)authoritiesList.get(i);

        String antPath = url.getUrl();//需要验证的URL

        String token = url.getToken();//拥有此处权限才能访问URl

         

            Collection<ConfigAttribute> atts = new ArrayList<ConfigAttribute>();  

            ConfigAttribute ca = new SecurityConfig(token);  

            atts.add(ca);

 

            this.resourceMap.put(antPath, atts);     

        }  

        System.out.println("---加载所有的权限配置---"); 

        /*//通过硬编码设置，resouce和role 

        resourceMap = new HashMap<String, Collection<ConfigAttribute>>(); 

        Collection<ConfigAttribute> atts = new ArrayList<ConfigAttribute>(); 

        ConfigAttribute ca = new SecurityConfig("/ROLE_ADD");  

        atts.add(ca);  

        resourceMap.put("/jsp/admin.jsp", atts);  

        */   

          

    }  

   

    // According to a URL, Find out permission configuration of this URL.  

    public Collection<ConfigAttribute> getAttributes(Object object) throws IllegalArgumentException {  

        if (logger.isDebugEnabled()) {  

            logger.debug("getAttributes(Object) - start"); //$NON-NLS-1$  

        }  

        // guess object is a URL.  

        String url = ((FilterInvocation) object).getRequestUrl();  

        Iterator<String> ite = resourceMap.keySet().iterator();  

        while (ite.hasNext()) {  

            String resURL = ite.next();  

            if (urlMatcher.pathMatchesUrl(url, resURL)) {  

                Collection<ConfigAttribute> returnCollection = resourceMap.get(resURL);  

                if (logger.isDebugEnabled()) {  

                    logger.debug("getAttributes(Object) - end"); //$NON-NLS-1$  

                }  

                return returnCollection;  

            }  

        }  

        if (logger.isDebugEnabled()) {  

            logger.debug("getAttributes(Object) - end"); //$NON-NLS-1$  

        }

       

        return null;  

    }  

   

    public boolean supports(Class<?> clazz) {  

        return true;  

    }  

    public Collection<ConfigAttribute> getAllConfigAttributes() {  

      

       Set<ConfigAttribute> allAttributes = new HashSet<ConfigAttribute>();

        for (Map.Entry<String,  Collection<ConfigAttribute>> entry : resourceMap.entrySet()) {

            for (ConfigAttribute attrs : entry.getValue()) {

                allAttributes.add(attrs);

            }

        }

        return allAttributes;

    }

   

    public IBasicAuthoritiesDAO getBasicAuthoritiesHibernateDAO() {

       return basicAuthoritiesHibernateDAO;

    }

    public void setBasicAuthoritiesHibernateDAO(

           IBasicAuthoritiesDAO basicAuthoritiesHibernateDAO) {

       this.basicAuthoritiesHibernateDAO = basicAuthoritiesHibernateDAO;

    }  

   

   

}

3.2认证用户实现UserDetailsService类类

package com.bestsoft.ssh.service.impl.security;

/**

 * 查询用户和用户对应的权限

 * @author zhangchaobing

 *

 */

public class UserDetailServiceImpl implements UserDetailsService {

    @Resource(name="basicUserHibernateDAO")

    private IBasicUsersDAO basicUserHibernateDAO;

   

    public UserDetails loadUserByUsername(String username){

       try{

           //查询用户

           BasicUsers user = basicUserHibernateDAO.getBasicUser(username);

           BasicUsers returnUser = null;

           if(user !=null || !user.equals("")){

             

              returnUser = new BasicUsers(user.getUserId(),user.getUsername(),user.getPassword(),getAuthorities(user.getUserId()),DateTime.getStringDate());

           }

           return returnUser;

       }catch (DataAccessException repositoryProblem) {

           repositoryProblem.printStackTrace();

           throw new AuthenticationServiceException("数据连接失败,服务器忙,请稍后再试");

       }

    }

//加载用户对应的权限

    public List<GrantedAuthority> getAuthorities(int userId) {

        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();  

authorities.add(new GrantedAuthorityImpl("ROLE_ANONYMOUS")); //赋予一个临时权限

        return authorities;

    }

}

 

3.3为了实现对验证码的验证，这里重写登陆验证Filter 继承

       UsernamePasswordAuthenticationFilter类

 

package com.bestsoft.ssh.service.impl.security;

 

/**

 * 验证用户信息

 * @author zhangchaobing

 *

 */

public class ValidateCodeUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter{

   

    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {

      

       //zcb  添加对验证码验证

       checkValidateCode(request);

       return super.attemptAuthentication( request,  response);

    }

   

    /**

     * 验证 验证码

     * @param request

     */

    protected void checkValidateCode(HttpServletRequest request) {  

        String sessionValidateCode = (String) request.getSession().getAttribute("rand"); 

        String validateCodeParameter = request.getParameter("randNum");

       

       if (StringUtils.isEmpty(validateCodeParameter)|| StringUtils.isEmpty(sessionValidateCode) || !sessionValidateCode.equalsIgnoreCase(validateCodeParameter)) {  

            throw new AuthenticationServiceException("验证码不正确!");  

        }  

       

    } 

   

    /**

     * 重写父类的方法，在验证用户完成调用的方法

     */

    protected void successfulAuthentication(

           HttpServletRequest arg0, HttpServletResponse arg1,

           Authentication arg2) throws IOException, ServletException  {

      

          String username = obtainUsername(arg0);

                 arg0.getSession().setAttribute("userName",arg0.getParameter("j_username"));

          super.successfulAuthentication(arg0, arg1, arg2);

       }

 

}

 

 

4. 总结

  对于spring securiyt3.0的默认配置很简单，但是为了满足系统的需求是需要重写很多配置的，一般需要好好研究一下源码，才能明白

注：关于<一>的配置没有通过网易审核，不知道网易怎么搞的
