url重写_urlrewritefilter的例子

java实现URL重写的的方法很很多种,下面举一个使用urlrewritefilter的例子

1.在web.xml中声明一个Filter<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>

 2.WEB-INF目录下新建urlrewrite.xml(在其中进行重写规则的定义，它使用正则表达式来进行规则的定义)

<?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">

<urlrewrite>

        <rule>
            <from>/test.html</from>
            <to type="redirect">%{context-path}/page.html</to>
        </rule>

        <rule>
            <from>/param/(.*)</from>
            <to>/param.jsp?param=$1</to>
        </rule>

</urlrewrite>

 下面是一个简单的测试

        <rule>
            <from>/test.html</from>
            <to type="redirect">%{context-path}/page.html</to>
        </rule>
是将test.html的访问请求转发给page.html

        <rule>
            <from>/param/(.*)</from>
            <to>/test.jsp?param=$1</to>
        </rule>
将test.jsp?param=111这种请求重写为/param/111
