DispatcherServlet
1。初始化默認配置
?private static final String DEFAULT_STRATEGIES_PATH = "DispatcherServlet.properties";

static {
??// Load default strategy implementations from properties file.
??// This is currently strictly internal and not meant to be customized
??// by application developers.
??try {
???ClassPathResource resource = new ClassPathResource(DEFAULT_STRATEGIES_PATH, DispatcherServlet.class);
???InputStream is = resource.getInputStream();
???try {
????defaultStrategies.load(is);
???}
???finally {
????is.close();
???}
??}
??catch (IOException ex) {
???throw new IllegalStateException("Could not load 'DispatcherServlet.properties': " + ex.getMessage());
??}
?}

DispatcherServlet.properties 里面內(nèi)容為：
org.springframework.web.servlet.LocaleResolver=org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver

org.springframework.web.servlet.ThemeResolver=org.springframework.web.servlet.theme.FixedThemeResolver

org.springframework.web.servlet.HandlerMapping=org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

org.springframework.web.servlet.HandlerAdapter=org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter,\
?org.springframework.web.servlet.mvc.throwaway.ThrowawayControllerHandlerAdapter

org.springframework.web.servlet.ViewResolver=org.springframework.web.servlet.view.InternalResourceViewResolver

可以看出如果沒有相應(yīng)的配置，DispatcherServlet就會調(diào)用默認設(shè)置

<form?name="form1"?action=""?method="post">
<select?name="s1">
????<option?value="aa">aaaaa</option>
????<option?value="bb">bbbb</option>
????<option?value="cc">ccccc</option>
????<option?value="dd">dddd</option>
????<option?value="ee">eeee</option>
</select>
</form>
假設(shè)在修改頁面時，s1的值是dd,那么默認應(yīng)該選中的是dddd這個option，那我們可以用如下的JS代碼來實現(xiàn)：
<script?language="JavaScript">
<!--
for?(i=0;i<document.form1.s1.options.length;i++)
{?
?????if(document.form1.s1.options[i].value=="<%=Rs("xxxxx")%>")
?????{
?????????document.form1.s1.options[i].selected=true;break;
?????}?
}
//-->
</script>

<%=Rs("xxxxx")%>的值為dd 最近在研究Spring MVC框架～發(fā)現(xiàn)一個問題.
根據(jù)源碼的實例：
It is named based on the servlet-name from web.xml with '-servlet' appended. This is a standard naming convention used in the Spring Framework
那么配置文件不就是只能有一個了嗎？那么要是在大型的系統(tǒng)里面，Control很多的情況下。這個文件不回冗余嗎？調(diào)試不好調(diào)試，找bean 也不好找。那要怎么樣才能配置多個配置文件了？？？？
