Struts的安裝與基本配置
我們主要針對Struts1.1版本進(jìn)行講解，這里假定讀者已經(jīng)配置好java運(yùn)行環(huán)境和相應(yīng)的Web容器，本文例子所使用的是j2sdk和Tomcat4.1.27.下面，將采用類似于step by step的方式介紹其基礎(chǔ)部分。
安裝Struts
到http://jakarta.apache.org/ 下載Struts的安裝文件，本文例子使用的是1.1版。
接下來您要進(jìn)行如下幾個步驟來完成安裝：
1、解壓下載的安裝文件到您的本地硬盤
2、生成一個新的Web應(yīng)用，假設(shè)我們生成的應(yīng)用程序的根目錄在tomcat下的/Webapps/mystruts目錄。在server.xml文件中為該應(yīng)用新建一個別名如/mystruts
3、從第1步解壓的文件中拷貝下列jar文件到/Webapps/mystruts/WEB-INF/lib目錄，主要文件有如下一些。
quote:
struts.jar
commons－beanutils.jar
commons－collections.jar
commons－dbcp.jar
commons－digester.jar
commons－logging.jar
commons－pool.jar
commons－services.jar
commons－validator.jar

4、創(chuàng)建一個web.xml文件，這是一個基于servlet的Web應(yīng)用程序都需要的部署描述文件，一個Struts Web應(yīng)用，在本質(zhì)上也是一個基于servlet的Web應(yīng)用，它也不能例外。
Struts有兩個組件要在該文件中進(jìn)行配置，它們是：ActionServlet和標(biāo)簽庫。下面是一個配置清單：

上面我們在web.xml中完成了對servlet和標(biāo)簽庫的基本配置，而更多的框架組件要在struts-config.xml中進(jìn)行配置：
5、創(chuàng)建一個基本的struts-config.xml文件，并把它放在/Webapps/mystruts/WEB-INF/目錄中，該文件是基于Struts應(yīng)用程序的配置描述文件，它將MVC結(jié)構(gòu)中的各組件結(jié)合在一起，開發(fā)的過程中會不斷對它進(jìn)行充實(shí)和更改。在Struts1.0時，一個應(yīng)用只能有一個這樣的文件，給分工開發(fā)帶來了一些不便，在Struts1.1時，可以有多個這樣的文件，將上述缺點(diǎn)克服了。需在該文件中配置的組件有：data-sources
quote:
global-execptions
form-beans
global-forwards
action-mappings
controller
message-resources
plug-in
配置清單如下：
quote:
//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
|
到此為止，我們已經(jīng)具備了完成一個最簡單Struts應(yīng)用的所需的各種組件。前面已經(jīng)提到，在開發(fā)過程中我們會不斷充實(shí)和修改上面兩個配置描述文件。
