【JavaWeb】使用URLRewriteFilter访问地址省略后缀名.jsp

现在的访问地址必须访问一长串的地址/文件名.jsp，想省略中间一长串的地址和后缀名，使用UrlReWirteFilter就可以做到。

#-> UrlRewriteFilter 官网：http://tuckey.org/urlrewrite/

使用方法，官网已经写的很清楚了，如上图所示。

 （1）添加urlrewritefil-4.0.3.jar到WEB-INF/lib，使用Maven的话，直接在pom.xml文件里添加如下依赖

<dependency>
    <groupId>org.tuckey</groupId>
    <artifactId>urlrewritefilter</artifactId>
    <version>4.0.3</version>
</dependency>

（2）WEB-INF/web.xml 添加如下代码

<filter>
    <filter-name>UrlRewriteFilter</filter-name>
    <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>UrlRewriteFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

（3）添加urlrewrite.xml到WEB-INF文件夹下（Maven用户：src/main/webapp/WEB-INF/）

urlrewrite.xml官网提供下载，直接copy到工程WEB-INF文件夹下，原始内容如下：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN"
        "http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">

<!--

    Configuration file for UrlRewriteFilter
    http://www.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 strings match Mozilla/1, Mozilla/2, Mozilla/3 or Mozilla/4.

    Centralised browser detection
        <rule>
            <condition name="user-agent">Mozilla/[1-4]</condition>
            <set type="request" name="browser">moz</set>
        </rule>
    eg, all requests will be checked against the condition and if matched
    request.setAttribute("browser", "moz") will be called.

    -->

</urlrewrite>

新增修改自定义的内容，将原来的访问地址/pages/registration.jsp映射成registration

<rule>
    <from>^/registration$</from>
    <to type="forward">/pages/registration.jsp</to>
</rule>

重新运行项目，现在可以使用新的映射地址访问啦

before：http://localhost:8080/BusinessTrip/pages/registration.jsp

after：http://localhost:8080/BusinessTrip/registration
