------------------------------------------------------------------------------------------------------------------------------------

一。新建java webproject 這里取名為shirodemo

二。加入依賴的jar包。例如以下：

三。加入web對shiro的支持

如第一篇文章所述，在此基礎上添加webs.xml部署描寫敘述：

<listener><listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class></listener><filter><filter-name>shiro</filter-name><filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class></filter><filter-mapping><filter-name>shiro</filter-name><url-pattern>/*</url-pattern></filter-mapping>

四。加入jsp頁面登陸button以及標簽支持：

<%String user = request.getParameter("username");String pwd = request.getParameter("password"); if(user != null && pwd != null){Subject sub = SecurityUtils.getSubject();String context = request.getContextPath();try{sub.login(new UsernamePasswordToken(user.toUpperCase(),pwd));out.println("登錄成功");}catch(IncorrectCredentialsException e){out.println("{success:false,msg:'username和password不對！'}");}catch(UnknownAccountException e){out.println("{success:false,msg:'用戶名不存在。'}");}return; } %>

在jsp頁面中添加username與password登陸框。

五。新建realm實現

package com.susheng.shiro;import javax.annotation.PostConstruct;import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.IncorrectCredentialsException; import org.apache.shiro.authc.LockedAccountException; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authc.UnknownAccountException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.authc.credential.HashedCredentialsMatcher; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.cache.CacheManager; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import org.apache.shiro.subject.Subject; import org.slf4j.Logger; import org.slf4j.LoggerFactory;//認證數據庫存儲 public class ShiroRealm extends AuthorizingRealm {public Logger logger = LoggerFactory.getLogger(getClass());final static String AUTHCACHENAME = "AUTHCACHENAME";public static final String HASH_ALGORITHM = "MD5";public static final int HASH_INTERATIONS = 1;public ShiroDbRealm() {// 認證super.setAuthenticationCachingEnabled(false);// 授權super.setAuthorizationCacheName(AUTHCACHENAME);}// 授權@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {if (!SecurityUtils.getSubject().isAuthenticated()) {doClearCache(principalCollection);SecurityUtils.getSubject().logout();return null;}// 加入角色及權限信息SimpleAuthorizationInfo sazi = new SimpleAuthorizationInfo();return sazi;}// 認證@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {UsernamePasswordToken upToken = (UsernamePasswordToken) token;String userName = upToken.getUsername();String passWord = new String(upToken.getPassword());AuthenticationInfo authinfo = new SimpleAuthenticationInfo(userName, passWord, getName());return authinfo;}/*** 設定Password校驗的Hash算法與迭代次數.*/@PostConstructpublic void initCredentialsMatcher() {HashedCredentialsMatcher matcher = new HashedCredentialsMatcher(HASH_ALGORITHM);matcher.setHashIterations(HASH_INTERATIONS);setCredentialsMatcher(matcher);} }

六。shiro.ini文件內容添加對realm的支持。

七。tomcat添加對這個應用的部署。啟動tomcat，輸入相應的url。

查看實現效果：

登錄界面的顯示

點擊登錄之后，插入了shiro的實現。

臨時沒有進行實質認證。僅僅是大概搭建的shiro環境。

自己插入自己的realm實現就能夠了。

OK。如今。以及實現了對web的支持。
