url rewrite和struts2整合

在qieqie这里http://www.iteye.com/topic/53834

发现了一个好东西，但按照他这里在项目里配置发现不成功

今天在把之前在网上收集的资料找了下，找到答案

在struts的filter-mapping中加入以下就可以了

Xml代码  

1. <filter-mapping>   
2.         <filter-name>struts2 </filter-name>   
3.         <url-pattern>*.do </url-pattern>   
4.         <dispatcher>REQUEST </dispatcher>    
5.         <dispatcher>FORWARD </dispatcher>    
6.        <dispatcher>INCLUDE </dispatcher>    
7. </filter-mapping>  

 

如下：

Xml代码  

1. <!-- Character Encoding filter -->  
2.     <filter>  
3.         <filter-name>encodingFilter</filter-name>  
4.         <filter-class>  
5.             org.springframework.web.filter.CharacterEncodingFilter  
6.         </filter-class>  
7.         <init-param>  
8.             <param-name>encoding</param-name>  
9.             <param-value>UTF-8</param-value>  
10.         </init-param>  
11.     </filter>  
12.     <!-- Hibernate Open Session In View filter-->  
13.     <filter>  
14.         <filter-name>osivFilter</filter-name>  
15.         <filter-class>  
16.             org.springframework.orm.hibernate3.support.OpenSessionInViewFilter  
17.         </filter-class>  
18.     </filter>  
19.     <!-- UrlRewriteFilter filter -->  
20.     <filter>  
21.         <filter-name>UrlRewriteFilter</filter-name>  
22.         <filter-class>  
23.             org.tuckey.web.filters.urlrewrite.UrlRewriteFilter  
24.         </filter-class>  
25.         <init-param>  
26.             <param-name>logLevel</param-name>  
27.             <param-value>WARN</param-value>  
28.         </init-param>  
29.     </filter>  
30.         <!-- Struts2 filter -->  
31.     <filter>  
32.         <filter-name>struts2-cleanup</filter-name>  
33.         <filter-class>  
34.             org.apache.struts2.dispatcher.ActionContextCleanUp  
35.         </filter-class>  
36.     </filter>  
37.         <filter>  
38.         <filter-name>struts2</filter-name>  
39.         <filter-class>  
40.             org.apache.struts2.dispatcher.FilterDispatcher  
41.         </filter-class>  
42.     </filter>  
43.     <filter-mapping>  
44.         <filter-name>encodingFilter</filter-name>  
45.         <url-pattern>/*</url-pattern>  
46.     </filter-mapping>  
47.   
48.       
49.     <filter-mapping>  
50.         <filter-name>osivFilter</filter-name>  
51.         <url-pattern>/*</url-pattern>  
52.     </filter-mapping>  
53.   
54.     <filter-mapping>  
55.         <filter-name>UrlRewriteFilter</filter-name>  
56.         <url-pattern>/*</url-pattern>  
57.         <dispatcher>REQUEST</dispatcher>  
58.         <dispatcher>FORWARD</dispatcher>  
59.     </filter-mapping>  
60.   
61.   
62.     <filter-mapping>  
63.         <filter-name>struts2-cleanup</filter-name>  
64.         <url-pattern>/*</url-pattern>  
65.         <dispatcher>REQUEST</dispatcher>    
66.         <dispatcher>FORWARD</dispatcher>   
67.     </filter-mapping>  
68.   
69.     <filter-mapping>  
70.         <filter-name>struts2 </filter-name>   
71.         <url-pattern>/*</url-pattern>   
72.         <dispatcher>REQUEST</dispatcher>    
73.         <dispatcher>FORWARD</dispatcher>   
74.     </filter-mapping>

1、在web.xml中EncodingFilter的位置应该在Struts2的FilterDispatcher之前，道理很简单，要先调整字符集，再进入Action。 

2、如果使用Urlrewrite，要指定filter-mapping的dispatcher方式，如下 
<filter-mapping> 
    <filter-name>Struts2</filter-name> 
    <url-pattern>/*</url-pattern> 
    <dispatcher>REQUEST</dispatcher> 
    <dispatcher>FORWARD</dispatcher> 
</filter-mapping> 

3、在做上传文件的时候，要在web.xml中增加ActionContextCleanUp这个filter，如果不增加，会发生第一次上传取不到文件的情况 
<filter> 
  <filter-name>struts-cleanup</filter-name> 
  <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class> 
  </filter> 
  <filter-mapping> 
    <filter-name>struts-cleanup</filter-name> 
    <url-pattern>/*</url-pattern> 
  </filter-mapping> 
按照Struts2的API，filter的顺序是 
struts-cleanup filter 
SiteMesh filter 
FilterDispatcher

第一个常用个规则就是站内的简单重写。 
<rule> 
  <from></from> 
  <to type="forward></to> 
</rule> 
  <from></from>写上你自己定义的访问地址，<to type="forward></to>就是实际的访问地址。比如我们实际的访问地址是：http://yousite.com/entity.htm ?category=user&page=2.而我们想把它重写为http://yousite.com/entity/uesr/page_2.html。这样看起来比我们实际的要好看的多。我们就应该这样的写：  
<rule> 
  <from>^/(\w+)/(\w+)/page_(\d+)\.html$</from> 
  <to type="forward">/$1.htm?category=$2&amp;page=$3</to> 
</rule> 
   简单的介绍一下常用的正规表示式： 
代码 说明 
. 匹配除换行符以外的任意字符 
\w 匹配字母或数字或下划线或汉字 
\s 匹配任意的空白符 
\d 匹配数字 
\b 匹配单词的开始或结束 
^ 匹配字符串的开始 
$ 匹配字符串的结束 

常用的&要用  &amp;来表示。$1,$2代表与你配置正规表达式>/(\w+)/(\w+)/相对应的参数。<to type="forward">默认的是 type="forward". 
  另一个常用的规则就是连接外部的网站。就要用到。<to type="redirect"> 
<rule> 
     <from>^/rss/yahoo\.html$</from> 
       <to type="redirect">    http://add.my.yahoo.com/rss? url=http://feed.feedsky.com/MySiteFeed 
      </to> 
</rule>
