Struts2中利用filter、session實現(xiàn)安全訪問和身份認(rèn)證

1、Struts2 中利用中利用 filter、session 實現(xiàn)安全訪問和身份認(rèn)證實現(xiàn)安全訪問和身份認(rèn)證來自原博客鏈接： http:/ 軟件JDK 1.7Apach Tomcat 72、通過 eclipse 創(chuàng)建 Dynamic Web Project 后,導(dǎo)入相應(yīng)的 Struts2 的 jar 文件：3、導(dǎo)入 jar 包后，創(chuàng)建如下圖所示項目相應(yīng)目錄：權(quán)限說明（1） 根目錄（WebContent）下的資源,如：index.jsp 和 login.jsp，允許匿名訪問。（2）Admin目錄下的admin.jsp只允許角色為”admin”的用戶訪問。User目錄下的user.jsp只允許角色為”

2、user”的用戶訪問4、相應(yīng)的 jsp 代碼如下：index.jsp:html view plain copy.6.7.Insert title here1.12.13.welcome to you !0.21.login.jsp:html view plain copy3.base href=14.15.Insert title here9.20.21.用戶名5.密碼8.user.
