URLRewrite地址重定向的实现
URLRewrite就是我们通常说的地址重写,用户得到的全部都是经过处理后的URL地址。其优点有:
(1)提高安全性,可以有效的避免一些参数名、ID等完全暴露在用户面前,如果用户随便乱输的话,不符合规则的话直接会返回个404或错误页面,这比直接返回500或一大堆服务器错误信息要好的多。
(2)美化URL,去除了那些比如*.do之类的后缀名、长长的参数串等,可以自己组织精简更能反映访问模块内容的URL。
(3)更有利于搜索引擎的收入,通过对URL的一些优化,可以使搜索引擎更好的识别与收录网站的信息。
实现过程:
1 参考http://blog.csdn.net/haishu_zheng/article/details/51490299,用第二种方法创建一个名为urlrewrite_demo的Maven工程。
2 文件目录结构如下图所示
3 在pom.xml中添加四个jar包:
spring-webmvc
spring-context-support
urlrewritefilter
freemarker

注意:这里的<from>和<to>决定了
http://localhost:8080/urlrewrite_demo 映射为
http://localhos:8080/urlrewrite_demo/service/login/toLoginIndex
假如<from>/$</from>改为<from>/abc</from>,则
http://localhost:8080/urlrewrite_demo/abc 映射为
http://localhos:8080/urlrewrite_demo/service/login/toLoginIndex
10 将urlrewrite_demo添加进Tomcat7中并运行
在浏览器中输入http://localhost:8080/urlrewrite_demo
显示结果为
