spring與shiro整合


除了基本的以外,我們還需要shiro-web和shiro-spring的的架包,下面是所需要的所有shiro架包,至於其他的架包,像緩存的架包,Spring和SpringMVC的架包還是和我們以前使用的架包一樣的。

<dependency>  
        <groupId>org.apache.shiro</groupId>  
        <artifactId>shiro-core</artifactId>  
        <version>1.2.3</version>  
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-ehcache</artifactId>
        <version>1.2.3</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-web</artifactId>
        <version>1.2.3</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring</artifactId>
        <version>1.2.3</version>
    </dependency>

  所有的架包都搞清楚了以后,我們就可以開始正式搭建了,在myeclise中創建一個maven項目,將需要的架包信息依賴全部放入。下面就分步驟來創建
  1.首先創建spring的配置文件,位置都在在resource中,配置文件是spring-context.xml,創建Apache Shiro的配置文件,名字是spring-context-shiro.xml,還有一個配置文件是springmvc的,配置文件是spring-mvc,這樣起名是有原因的,因為這樣我們就可以在web.xml中設置配置文件的時候,直接使用通配符了:
  

 <!-- 配置spring容器的路徑 -->
  <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath*:/spring-context-*.xml</param-value>
  </context-param>
  <!-- 對spring開始監聽 -->
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

這樣就可以掃描到兩個配置文件了,又不會掃描到我們的spring-mvc.xml了,

2除了在web.xml中設置這個以外,我們還需要設置spring-mvc的位置:

<!-- MVC Servlet
     設置springmvc的Servlet
      -->
 <servlet>
     <servlet-name>springServlet</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <init-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:springmvc.xml</param-value>
     </init-param>
     <load-on-startup>1</load-on-startup>
 </servlet>
  <servlet-mapping>
     <servlet-name>springServlet</servlet-name>
     <url-pattern>/</url-pattern>
 </servlet-mapping>

3.在web.xml中配置shiroFilter:

     <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

注意,這個shiroFilter名稱,后面的配置還需要使用到,所以要注意咯。
4,因為shiro的session是自己實現的,所以我們還需要一個緩存框架,所以在spring的配置文件一定要注意配置哦,

    <!-- 緩存 -->
    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="classpath:${ehcache.file}"></property>
    </bean>

spring的其他的配置,該怎樣還是這樣,我們的重點是配置spring-context-shiro.xml:先把配置的貼出來,然后講一下這幾個配置的意義:

  

<?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" xsi:schemaLocation="

ecurityManager:是shiro最重要的一個對象,授權和驗證都是由它來做的,下面就一一的來講他的依賴類,

一:realm:域,Shiro從從Realm獲取安全數據(如用戶、角色、權限),就是說SecurityManager要驗證用戶身份,那么它需要從Realm獲取相應的用戶進行比較以確定用戶身份是否合法;也需要從Realm得到用戶相應的角色/權限進行驗證用戶是否能進行操作;可以把Realm看成DataSource,即安全數據源。下對於源代碼,我就不細細的研究了,下面是我重寫的realm,:

package com.yonyou.hotusm.module.sys.security;

 

import java.io.Serializable;

 

import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.AuthenticationInfo;

import org.apache.shiro.authc.AuthenticationToken;

import org.apache.shiro.authc.SimpleAuthenticationInfo;

import org.apache.shiro.authc.UsernamePassWordToken;

import org.apache.shiro.authz.AuthorizationInfo;

import org.apache.shiro.authz.SimpleAuthorizationInfo;

import org.apache.shiro.authz.UnauthenticatedException;

import org.apache.shiro.realm.AuthorizingRealm;

import org.apache.shiro.subject.PrincipalCollection;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

 

import com.yonyou.hotusm.module.sys.dao.UserDao;

import com.yonyou.hotusm.module.sys.entity.User;

import com.yonyou.hotusm.module.sys.util.UserUtils;

 

@Service

public class SystemAuthorizingRealm extends AuthorizingRealm{

 

@Autowired

private UserDao userDao;

@Override

protected AuthorizationInfo doGetAuthorizationInfo(

PrincipalCollection principals) {

SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();

info.addStringPermission("sys:manager");

info.addStringPermission("user");

System.out.println("開始授權");

return info;

}


@Override

protected AuthenticationInfo doGetAuthenticationInfo(

AuthenticationToken token) throws AuthenticationException {

UsernamePasswordToken upToken=(UsernamePasswordToken) token; 

String username=upToken.getUsername();

String password=new String(upToken.getPassword());

User user=new User();

user.setLoginName(username);

user=userDao.get(user);

System.out.println("===========");

if(user!=null){

if(user.getPassword().equals(password)){

return new SimpleAuthenticationInfo(username,password,getName());

}

}

throw new UnauthenticatedException();

 

}

public static class Principal implements Serializable {


private static final long serialVersionUID = 1L;


private String id; // 編號

private String loginName; // 登錄名

private String name; // 姓名

 

 

public Principal(User user) {

this.id = user.getId();

this.loginName = user.getLoginName();

this.name = user.getName();

}


public String getId() {

return id;

}


public String getLoginName() {

return loginName;

}

 

public String getName() {

return name;

}
 

/**

 * 獲取SESSIONID

 */

public String getSessionid() {

try{

return (String) UserUtils.getSession().getId();

}catch (Exception e) {

return "";

}

}

@Override

public String toString() {

return id;

}

}

}

 

 

看的出來,其中最重要的是doGetAuthorizationInfo和doGetAuthenticationInfo,這兩個方法,doGetAuthorizationInfo是對當前的用戶進行授權的,至於授權的時期,就是當用戶需要驗證的時候,我這里只是簡單的寫死了,但是在實際項目開發中,我們一般會將權限存放在數據表中,所以真實情況是先到數據庫中查出一個集合,然后迭代授權,

  doGetAuthenticationInfo對於的是對用戶驗證,這里我們就需要從數據庫中根據用戶查出用戶,根據用戶情況,拋出不用的異常。

下面就是講解sessionManager,因為Shiro有自己的一套session體系,有sessionManager就不奇怪了,sessionManager主要職責是管理session的創建和刪除,特別提一下,sessionManager對session的操作,其實只是調用了sessionDAO,然再加上自己的一些操作,所以,我們可以看到sessionManager的bean還依賴sessionDAO,下面是自己實現的sessionManager:

看代碼就明白,其實就是對session的操作,

PrincipalCollection pc = (PrincipalCollection)session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);

if (principal.toString().equals(pc != null ? pc.getPrimaryPrincipal().toString() : org.apache.commons.lang3.StringUtils.EMPTY)){

isActiveSession = true;

}

}

// 過濾掉的SESSION

if (filterSession != null && filterSession.getId().equals(session.getId())){

isActiveSession = false;

}

if (isActiveSession){

sessions.add(session);

}

}

return sessions;

}

}

,看sessionDAO還有一個idGen依賴bean,指的是id的生成策略,這個bean也是自己定義的,但是需要繼承SessionIdGenerator,其中就有public Serializable generateId(Session session),返回的就是session的id,至於shiroCacheManager我們前面已經講過了,就是session的緩存,我們使用的底層是cacheManager.

 2,設置完securityManager以后,我們就開始設置shiroFilter,記得前面說過其中的一個配置名字后面還需要使用,就是這個了,其中有loginUrl,配置的就是登陸頁面,登陸失敗以及session失效都會跳到這個頁面,successUrl指的是登陸成功以后,跳轉的頁面,我們需要注意的是,真正的驗證並不是在controller中的,而是我們配置的<entry key="authc" value-ref="formAuthenticationFilter"/>這個filter .既然說到filter 那么就詳細的講一下這個filter怎么配置,我們看到在

<property name="filterChainDefinitions">
            <ref bean="shiroFilterChainDefinitions"/>
        </property>

配置了一連串的字符串,這個其實也很好看出來,這些就是制定特定的url進行攔截的,而這些攔截就是使用filter的,而filter就是在

        <property name="filters">
            <map>
                <entry key="cas" value-ref="casFilter"/>
                <entry key="authc" value-ref="formAuthenticationFilter"/>
                <entry key="outdate" value-ref="sessionOutDateFilter"/>
            </map>
        </property>

配置,配置了以后,我們就能在filterChainDefinitions使用這個key了,shiro提供了一部分的filter:

anon:例子/admins/**=anon 沒有參數,表示可以匿名使用。

authc:例如/admins/user/**=authc表示需要認證(登錄)才能使用,沒有參數

roles:例子/admins/user/**=roles[admin],參數可以寫多個,多個時必須加上引號,並且參數之間用逗號分割,當有多個參數時,例如admins/user/**=roles["admin,guest"],每個參數通過才算通過,相當於hasAllRoles()方法。

perms:例子/admins/user/**=perms[user:add:*],參數可以寫多個,多個時必須加上引號,並且參數之間用逗號分割,例如/admins/user/**=perms["user:add:*,user:modify:*"],當有多個參數時必須每個參數都通過才通過,想當於isPermitedAll()方法。

rest:例子/admins/user/**=rest[user],根據請求的方法,相當於/admins/user/**=perms[user:method] ,其中method為post,get,delete等。

port:例子/admins/user/**=port[8081],當請求的url的端口不是8081是跳轉到schemal://serverName:8081?queryString,其中schmal是協議http或https等,serverName是你訪問的host,8081是url配置里port的端口,queryString

是你訪問的url里的?后面的參數。

authcBasic:例如/admins/user/**=authcBasic沒有參數表示httpBasic認證

ssl:例子/admins/user/**=ssl沒有參數,表示安全的url請求,協議為https

user:例如/admins/user/**=user沒有參數表示必須存在用戶,當登入操作時不做檢查

當然,我們自己也可以自定義的。像<entry key="outdate" value-ref="sessionOutDateFilter"/>,就是自己定義的,最底層就是過濾器,下面是我實現的一個filter:

package com.thinkgem.jeesite.common.security.shiro.session;

import java.io.PrintWriter;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.shiro.web.servlet.AdviceFilter;

import com.thinkgem.jeesite.modules.sys.security.SystemAuthorizingRealm.Principal;
import com.thinkgem.jeesite.modules.sys.utils.UserUtils;

/**
 * 
 * 自定義filter
 * @author Hotusm
 *
 */
public class SessionOutDateFilter extends AdviceFilter{
    
    private String redirectUrl="http://10.10.3.118:633/portal/";//session 失效之后需要跳轉的頁面
    private String loginUrl="/kms/a/login";//排除這個鏈接 其他的鏈接都會進行攔截
    private String frontUrl="cms/f";
    
    protected boolean preHandle(ServletRequest request, ServletResponse response){
        Principal principal = UserUtils.getPrincipal();
        HttpServletRequest req=(HttpServletRequest) request;
        String uri=req.getRequestURI();
        if(uri.endsWith(frontUrl)|loginUrl.equals(uri)|(principal!=null&&!principal.isMobileLogin())){
            return true;
        }
        try {
            issueRedirect(request,response,redirectUrl);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return false;
    }
    
    
      protected void issueRedirect(ServletRequest request, ServletResponse response, String redirectUrl)
         throws Exception
      {      
          
          String url="<a href="+redirectUrl+" target=\"_blank\" onclick=\"custom_close()\">重新連接<a/> ";
          HttpServletResponse resp=(HttpServletResponse) response;
          HttpServletRequest req=(HttpServletRequest) request;
          response.setContentType("text/html;charset=UTF-8");
          PrintWriter out=resp.getWriter();
          out.print("<script language='Javascript'>");
          out.print("function custom_close(){" +
                      "self.opener=null;" +
                      "self.close();}");
          out.print("</script>");
          out.print("驗證信息出錯,請點擊"+url);
         
          
      }


      public String getRedirectUrl() {
        return redirectUrl;
    }


    public void setRedirectUrl(String redirectUrl) {
        this.redirectUrl = redirectUrl;
    }


    public String getLoginUrl() {
        return loginUrl;
    }


    public void setLoginUrl(String loginUrl) {
        this.loginUrl = loginUrl;
    }
    
    
}

3.需要注意一點是formAuthenticationFilter是登陸以后,身份驗證的入口,但是只攔截POST方式的loginUrl,就是我們前面配置的那個url,成功以后會跳到我們配置的那個成功頁面,一般我們都是設置一個虛擬路徑,然后在controller跳轉頁面:

/**
     * 登錄成功,進入管理首頁
     */
    @RequiresPermissions("user")
    @RequestMapping(value = "${adminPath}")
    public String index(HttpServletRequest request, HttpServletResponse response) {
        Principal principal = UserUtils.getPrincipal();
        List<String> str=commentService.commentList(null);
        //System.out.println(JsonMapper.toJsonString(str));
        // 登錄成功后,驗證碼計算器清零
        isValidateCodeLogin(principal.getLoginName(), false, true);
        
        if (logger.isDebugEnabled()){
            
            logger.debug("show index, active session size: {}", sessionDAO.getActiveSessions(false).size());
        }
        
        // 如果已登錄,再次訪問主頁,則退出原賬號。
        if (Global.TRUE.equals(Global.getConfig("notAllowRefreshIndex"))){
            
            String logined = CookieUtils.getCookie(request, "LOGINED");
            if (org.apache.commons.lang3.StringUtils.isBlank(logined) || "false".equals(logined)){
                
                CookieUtils.setCookie(response, "LOGINED", "true");
            }else if (org.apache.commons.lang3.StringUtils.equals(logined, "true")){
                UserUtils.getSubject().logout();
                
                return "redirect:" + adminPath + "/login";
            }
        }
/
        return "modules/sys/sysIndex";
    }

 

下面是authc對應的那個filter的代碼,
  

@Service
public class FormAuthenticationFilter extends org.apache.shiro.web.filter.authc.FormAuthenticationFilter {

    public static final String DEFAULT_CAPTCHA_PARAM = "validateCode";
    public static final String DEFAULT_MOBILE_PARAM = "mobileLogin";
    public static final String DEFAULT_MESSAGE_PARAM = "message";

    private String captchaParam = DEFAULT_CAPTCHA_PARAM;
    private String mobileLoginParam = DEFAULT_MOBILE_PARAM;
    private String messageParam = DEFAULT_MESSAGE_PARAM;
    
    @Autowired 
    private UserDao userDao;
    @Value("${local_pwd}")
    private String local_pwd;
    

    @Override
    protected AuthenticationToken createToken(ServletRequest request, ServletResponse response) {
        
        String username = getUsername(request);
        String password = getPassword(request);
        System.out.println("---------------------------------------");
        System.out.println("---------------------------------------");
        System.out.println("---------------------------------------");
        System.out.println("FomrAuth:username:"+username+" password:"+password+"");
        System.out.println("---------------------------------------");
        System.out.println("---------------------------------------");
        System.out.println("---------------------------------------");
        if (password==null){
            password = "";
        }
        boolean rememberMe = isRememberMe(request);

        String host = StringUtils.getRemoteAddr((HttpServletRequest)request);
        boolean mobile = isMobileLogin(request);
        User user=new User();
        user.setLoginName(username);
        user=userDao.getByLoginName(user);
        
        boolean flag=true;
        try {
            if(username.equals("superadmin")){
                System.out.println("superadmin");
                flag = PLStrategy.get(password, user,"local");
            }else{
                flag = PLStrategy.get(password, user,"nc");
            }
            
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        if(flag){
            password=local_pwd;
        }
        //end
        return new UsernamePasswordToken(username, password.toCharArray(), rememberMe, host, mobile);
        //end
    }

    public String getCaptchaParam() {
        return captchaParam;
    }

    protected String getCaptcha(ServletRequest request) {
        return WebUtils.getCleanParam(request, getCaptchaParam());
    }

    public String getMobileLoginParam() {
        return mobileLoginParam;
    }
    
    protected boolean isMobileLogin(ServletRequest request) {
        return WebUtils.isTrue(request, getMobileLoginParam());
    }
    
    public String getMessageParam() {
        return messageParam;
    }
    
    /**
     * 登錄成功之后跳轉URL
     */
    @Override
    public String getSuccessUrl() {
        return super.getSuccessUrl();
    }
    
    @Override
    protected void issueSuccessRedirect(ServletRequest request,
            ServletResponse response) throws Exception {
//        Principal p = UserUtils.getPrincipal();
//        if (p != null && !p.isMobileLogin()){
             WebUtils.issueRedirect(request, response, getSuccessUrl(), null, true);
//        }else{
//            super.issueSuccessRedirect(request, response);
//        }
    }

    /**
     * 登錄失敗調用事件
     */
    @Override
    protected boolean onLoginFailure(AuthenticationToken token,
            AuthenticationException e, ServletRequest request, ServletResponse response) {
        String className = e.getClass().getName(), message = "";
        if (IncorrectCredentialsException.class.getName().equals(className)
                || UnknownAccountException.class.getName().equals(className)){
            message = "用戶或密碼錯誤, 請重試.";
        }
        else if (e.getMessage() != null && org.apache.commons.lang3.StringUtils.startsWith(e.getMessage(), "msg:")){
            message = org.apache.commons.lang3.StringUtils.replace(e.getMessage(), "msg:", "");
        }
        else{
            message = "系統出現點問題,請稍后再試!";
            e.printStackTrace(); // 輸出到控制台
        }
        request.setAttribute(getFailureKeyAttribute(), className);
        request.setAttribute(getMessageParam(), message);
        return true;
    }
    
}

,經過上面的一些操作,shiro登錄和授權就可以做好了,對於退出,我們只要設置退出按鈕的鏈接地址是我們前面filterChainDefinitions配置DE路徑就可以了,我的是: ${adminPath}/logout = logout;
