Java中使用urlrewrite实现URL的重写

1.下载urlrewrite,官方下载地址：http://tuckey.org/urlrewrite/dist/urlrewritefilter-2.6.zip

2.解压缩文件，压缩包内文件copy到项目中(压缩包位置 -> 项目位置)：

urlrewrite-2.6.0-src/webapp/WEB-INF/lib/urlrewrite-2.6.0.jar -> WebRoot/WEB-INF/lib/urlrewrite-2.6.0.jar

urlrewrite-2.6.0-src/webapp/WEB-INF/urlrewrite.xml -> WebRoot/WEB-INF/urlrewrite.xml

3.修改urlrewrite.xml

Xml代码

1. <?xmlversion="1.0"encoding="utf-8"?>  

2. <!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"  

3. "http://tuckey.org/res/dtds/urlrewrite2.6.dtd">  

4.  

5. <!--  

6.  

7. Configuration file for UrlRewriteFilter  

8. http://tuckey.org/urlrewrite/  

9.  

10. -->  

11. <urlrewrite>  

12.    <rule>  

13.        <from>^/([a-z]+)$</from>  

14.        <totype= "forward">/world.jsp?id=$1</to>  

15.    </rule>  

16.    <rule>  

17.        <from>^/world/(.*)$</from>  

18.        <to>/world.jsp?tid=$1</to>  

19.    </rule>  

20.    <rule>  

21.        <from>^/(.*).html$</from>  

22.        <to>/test1/$1.jsp</to>  

23.    </rule>  

24.      

25.    <outbound-rule>  

26.        <note>  

27.         The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)  

28.         the url /rewrite-status will be rewritten to /test/status/.  

29.          

30.         The above rule and this outbound-rule means that end users should never see the  

31.         url /rewrite-status only /test/status/ both in thier location bar and in hyperlinks  

32.         in your pages.  

33.        </note>  

34.        <from>/rewrite-status</from>  

35.        <to>/test/status/</to>  

36.    </outbound-rule>  

37. </urlrewrite>  

4.将以下代码添加到web.xml里

Xml代码

1. <filter>  

2.        <filter-name>UrlRewriteFilter</filter-name>  

3.        <filter-class>  

4.             org.tuckey.web.filters.urlrewrite.UrlRewriteFilter  

5.        </filter-class>  

6.    </filter>  

7.    <filter-mapping>  

8.        <filter-name>UrlRewriteFilter</filter-name>  

9.        <url-pattern>/*</url-pattern>  

10.    </filter-mapping>  

<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>
    </filter-mapping>

<?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>

 </rule>

     <from>^/world/(.*)$</from>
     <to>/world.jsp?tid=$1</to>
 </rule>
 <rule>
  <from>^/(.*).html$</from>
  <to>/test1/$1.jsp</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

  </note> 
  <from>/rewrite-status</from> 
  <to>/test/status/</to> 
 </outbound-rule>
</urlrewrite>

rule是url重写规则,from是显示出来的地址,to是映射的实际地址,$1是重写参数,可以为多个,()里是匹配的正则表达式.
好了,在项目中新建world.jsp,启动tomcat,输入
http://localhost:8080/mysite/world/1

mysite是你的项目名

实际上访问的是http://localhost:8080/mysite/world.jsp?tid=1
这样就简单的实现了伪静态的效果
