URLRewriter实现伪静态

URLREwriter组件

下载地址:http://www.chx99.cn/file/URLRewriter.rar

 

实现url重写的步骤：

首先，通过上述的网址将URLREwriter组件下载到本地，放到项目下的/WEB-INF/lib目录下

再从网上找到如下的配置文件urlrewrite.xml，如下：（放在/WEB-INF目录下）

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"
        "http://tuckey.org/res/dtds/urlrewrite2.6.dtd">

<!--

    Configuration file for UrlRewriteFilter
    http://tuckey.org/urlrewrite/

-->
<urlrewrite>

    <rule>
        <note>
            The rule means that requests to /test/status/ will be redirected to /rewrite-status
            the url will be rewritten.
        </note>
        <from>/test/status/</from>
        <to type="redirect">%{context-path}/rewrite-status</to>
    </rule>

    <outbound-rule>
        <note>
            The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)
            the url /rewrite-status will be rewritten to /test/status/.

            The above rule and this outbound-rule means that end users should never see the
            url /rewrite-status only /test/status/ both in thier location bar and in hyperlinks
            in your pages.
        </note>
        <from>/rewrite-status</from>
        <to>/test/status/</to>
    </outbound-rule>

    <!--

    INSTALLATION

        in your web.xml add...

        <filter>
            <filter-name>UrlRewriteFilter</filter-name>
            <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
            <init-param>
                <param-name>logLevel</param-name>
                <param-value>WARN</param-value>
            </init-param>
        </filter>
        <filter-mapping>
            <filter-name>UrlRewriteFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

     EXAMPLES

     Redirect one url
        <rule>
            <from>/some/old/page.html</from>
            <to type="redirect">/very/new/page.html</to>
        </rule>

    Redirect a directory
        <rule>
            <from>/some/olddir/(.*)</from>
            <to type="redirect">/very/newdir/$1</to>
        </rule>

    Clean a url
        <rule>
            <from>/products/([0-9]+)</from>
            <to>/products/index.jsp?product_id=$1</to>
        </rule>
    eg, /products/1234 will be passed on to /products/index.jsp?product_id=1234 without the user noticing.

    Browser detection
        <rule>
            <condition name="user-agent">Mozilla/[1-4]</condition>
            <from>/some/page.html</from>
            <to>/some/page-for-old-browsers.html</to>
        </rule>
    eg, will pass the request for /some/page.html on to /some/page-for-old-browsers.html only for older
    browsers whose user agent srtings match Mozilla/1, Mozilla/2, Mozilla/3 or Mozilla/4.

    -->

</urlrewrite>

接下类就可以进行伪静态的实现了：

在上述的配置文件中加入下面代码：（缩减版）

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"
        "http://tuckey.org/res/dtds/urlrewrite2.6.dtd">

<!--

    Configuration file for UrlRewriteFilter
    http://tuckey.org/urlrewrite/

-->
<urlrewrite>

    <rule>
        <note>
            The rule means that requests to /test/status/ will be redirected to /rewrite-status
            the url will be rewritten.
        </note>
        <from>/test/status/</from>
        <to type="redirect">%{context-path}/rewrite-status</to>
    </rule>
   
        <rule>
            <from>/student.html/([a-z]+)</from>
            <to>/student.do?cmd=$1</to>
        </rule>
        <rule>
            <from>/student2.html/([a-z]+)_([0-9]+)</from>
            <to>/student.do?cmd=$1&amp;id=$2</to>
        </rule>

        
    <outbound-rule>
        <note>
            The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)
            the url /rewrite-status will be rewritten to /test/status/.

            The above rule and this outbound-rule means that end users should never see the
            url /rewrite-status only /test/status/ both in thier location bar and in hyperlinks
            in your pages.
        </note>
        <from>/rewrite-status</from>
        <to>/test/status/</to>
    </outbound-rule>

</urlrewrite>

 

最后在你的项目中就可以将路径写成伪静态的样子，如：

<a href="student.html/list">查看学生列表</a>

通过urlrewrite.xml的解析

<rule>
            <from>/student.html/([a-z]+)</from>
            <to>/student.do?cmd=$1</to>

  </rule>

就将该路径转化为：

student.do?cmd=list      (这是真实的请求路径)

 

 

又如：

<a href="student2.html/loadedit_2">查看学生列表</a>

通过urlrewrite.xml的解析

<rule>
            <from>/student2.html/([a-z]+)_([0-9]+)</from>
            <to>/student.do?cmd=$1&amp;id=$2</to>
 </rule>

就将该路径转化为：

student.do?cmd=loadedit&id=2      (这是真实的请求路径)

 

 

由于伪路径经常带有“/”，会将页面路径嵌套，所以建议使用绝对路径

在jsp页面上写上：

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

则上面的路径可以写成：

<a href="<%=basePath%>student2.html/loadedit_2">查看学生列表</a>
