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
六。shiro.ini文件內容添加對realm的支持。

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。
