一般的登入流程會有：使用者名稱不存在，密碼錯誤，驗證碼錯誤等..

在整合shiro後，應用程式的外部訪問許可權以及訪問控制交給了shiro來管理。

shiro提供了兩個主要功能：認證(Authentication)和授權(Authorization);認證的作用是證明自身可以訪問，一般是使用者名稱加密碼，授權的作用是誰可以訪問哪些資源，通過開發者自己的使用者角色許可權系統來控制。

shiro的會話管理和快取管理不在本文範圍內。

下面通過登入失敗的處理流程來介紹springmvc與shiro的整合。

依賴專案

在web.xml裡配置shiro

  <filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
      <param-name>targetFilterLifecycle</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

新建一個spring-context-shiro.xml配置shiro相關資訊，使用spring載入

新建一個登入認證過濾器FormAuthenticationFilter.java

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.web.util.WebUtils;
import org.springframework.stereotype.Service;

/**
 * 表單驗證（包含驗證碼）過濾類*/
@Service
public class FormAuthenticationFilter extends org.apache.shiro.web.filter.authc.FormAuthenticationFilter {
  public static final String DEFAULT_CAPTCHA_PARAM = "validateCode";

  private String captchaParam = DEFAULT_CAPTCHA_PARAM;

  public String getCaptchaParam() {
    return captchaParam;
  }

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

  protected AuthenticationToken createToken(ServletRequest request,ServletResponse response) {
    String username = getUsername(request);
    String password = getPassword(request);
    String locale = request.getParameter("locale");
    
    if (password == null) {
      password = "";
    }
    boolean rememberMe = isRememberMe(request);
    String host = getHost(request);
    String captcha = getCaptcha(request);
    return new UsernamePasswordToken(username,password.toCharArray(),locale,rememberMe,host,captcha);
  }
}

新建令牌類UsernamePasswordToken.java

package com.chunhui.webservice.modules.sys.security;

/**
 * 使用者和密碼（包含驗證碼）令牌類*/
public class UsernamePasswordToken extends org.apache.shiro.authc.UsernamePasswordToken {
  private static final long serialVersionUID = 1L;
  private String captcha;
  private String locale;
  
  public String getCaptcha() {
    return captcha;
  }

  public void setCaptcha(String captcha) {
    this.captcha = captcha;
  }

  public String getLocale() {
    return locale;
  }

  public void setLocale(String locale) {
    this.locale = locale;
  }

  public UsernamePasswordToken() {
    super();
  }

  public UsernamePasswordToken(String username,char[] password,boolean rememberMe,String host,String captcha) {
    super(username,password,host);
    this.captcha = captcha;
  }
  public UsernamePasswordToken(String username,String locale,host);
    this.captcha = captcha;
    this.locale = locale;
  }
}

最後一個是認證實現類SystemAuthorizationRealm:

package com.chunhui.webservice.modules.sys.security;
import java.io.Serializable;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.annotation.PostConstruct;

import com.chunhui.webservice.common.utils.EmployeeType;
import com.chunhui.webservice.common.utils.VertifyStatus;
import org.apache.commons.lang3.StringUtils;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.cache.Cache;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;

import com.chunhui.webservice.modules.sys.service.SystemService;
import com.chunhui.webservice.modules.sys.utils.SystemUtils;
import com.chunhui.webservice.modules.sys.web.LoginController;

/**
 * 系統安全認證實現類*/
@Service
@DependsOn({ "employeeDao","roleDao","menuDao" })
public class SystemAuthorizingRealm extends AuthorizingRealm {
  private SystemService systemService;

  /**
   * 認證回撥函式,登入時呼叫
   */
  @Override
  protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
    UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
// 判斷驗證碼
    Session session = SecurityUtils.getSubject().getSession();
    // 設定獨立的session會話超時時間 session.setTimeout(60000);
    String code = (String) session.getAttribute(ValidateCodeServlet.VALIDATE_CODE);
    if (token.getCaptcha() == null || !token.getCaptcha().toUpperCase().equals(code)) {
      throw new CaptchaException("驗證碼錯誤！");
    }　　　　　　　　　//如果帳號不存在，輸出
    //throw new UnknownAccountException();
    
    //如果帳號被禁用，輸出      
    //throw new DisabledAccountException();
      
    //儲存登入時選擇的語言
    SecurityUtils.getSubject().getSession().setAttribute("locale",token.getLocale());
    try{
      SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(new Principal(employee),employee.getPassword(),getName());
      return info;
    }catch (Throwable t){
      t.printStackTrace();
      throw new AuthenticationException();
    }
  }/**
   * 授權查詢回撥函式,進行鑑權但快取中無使用者的授權資訊時呼叫
   */
  @Override
  protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
    Principal principal = (Principal) getAvailablePrincipal(principals);
    Employee employee = getSystemService().getEmployeeByName(principal.getUsername());
    if (employee != null) {
      SystemUtils.putCache("employee",employee);
      SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
      List<Menu> list = SystemUtils.getMenuList();
      for (Menu menu : list) {
        if (StringUtils.isNotBlank(menu.getPermission())) {
          // 新增基於Permission的許可權資訊
          for (String permission : StringUtils.split(menu.getPermission(),",")) {
            info.addStringPermission(permission);
          }
        }
      }
      // 更新登入IP和時間
      getSystemService().updateEmployeeLoginInfo(employee.getId());
      return info;
    } else {
      return null;
    }
  }

  /**
   * 清空使用者關聯許可權認證，待下次使用時重新載入
   */
  public void clearCachedAuthorizationInfo(String principal) {
    SimplePrincipalCollection principals = new SimplePrincipalCollection(principal,getName());
    clearCachedAuthorizationInfo(principals);
  }

  /**
   * 清空所有關聯認證
   */
  public void clearAllCachedAuthorizationInfo() {
    Cache<Object,AuthorizationInfo> cache = getAuthorizationCache();
    if (cache != null) {
      for (Object key : cache.keys()) {
        cache.remove(key);
      }
    }
  }

  /**
   * 獲取系統業務物件
   */
  public SystemService getSystemService() {
    if (systemService == null) {
      systemService = SpringContextHolder.getBean(SystemService.class);
    }
    return systemService;
  }

  /**
   * 授權使用者資訊
   */
  public static class Principal implements Serializable {
    private static final long serialVersionUID = 1L;

    private String id;
    private String username;
    private String realname;
    private Map<String,Object> cacheMap;

    public Principal(Employee employee) {
      this.id = employee.getId();
      this.username = employee.getUsername();
      this.realname = employee.getRealname();
    }

    public String getId() {
      return id;
    }

    public String getUsername() {
      return username;
    }

    public String getRealname() {
      return realname;
    }

    public Map<String,Object> getCacheMap() {
      if (cacheMap == null) {
        cacheMap = new HashMap<String,Object>();
      }
      return cacheMap;
    }
  }
}

那麼在JSP頁面，可以通過獲取登入異常具體的異常型別來在頁面顯示錯誤原因

<%String error = (String) request.getAttribute(FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME);%>
　　　　　　　<c:set var="exp_type" value="<%=error %>"/>
      <c:set var="tips" value=""></c:set>
      <c:if test="${fn:contains(exp_type,'CaptchaException')}">
        <c:set var="tips" value="驗證碼錯誤"></c:set>
      </c:if>
      <c:if test="${fn:contains(exp_type,'FailVertifyException')}">
        <c:set var="tips" value="該賬號稽核未通過，不允許登陸!"></c:set>
      </c:if>
      <c:if test="${fn:contains(exp_type,'NotVertifyException')}">
        <c:set var="tips" value="該賬號正在稽核中... 不允許登陸!"></c:set>
      </c:if>
      <c:if test="${fn:contains(exp_type,'UnknownAccountException')}">
        <c:set var="tips" value="賬號不存在!"></c:set>
      </c:if>
      <c:if test="${fn:contains(exp_type,'DisabledAccountException')}">
        <c:set var="tips" value="賬號不允許登陸!"></c:set>
      </c:if>
      <c:if test="${fn:contains(exp_type,'IncorrectCredentialsException')}">
        <c:set var="tips" value="密碼錯誤!"></c:set>
      </c:if>
