需要用XML来排列吗？
我对声明元素中的排列感到困惑。 写有什么区别吗？
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/web-application-context.xml
</param-value>
</context-param>
如果我这样写：或者这样
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/web-application-context.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
I am confused with arrangement in the declaration Elements. Is there any difference if I write like this:
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/web-application-context.xml
</param-value>
</context-param>
Or like this?
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/web-application-context.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

是和否：
yes - 某些元素（如
web.xml的架构还定义了各种元素的顺序。否 - 其他元素的顺序无关，例如声明
Yes and no:
yes - the order of some elements like
<filter-mapping/>is relevant, as it will change the order of actual filters being applied. Also the schema forweb.xmldefines the order of various elements.no - the order of other elements is irrelevant, e.g. the order in which you declare
<servlet/>s. Also in your example it doesn't make any difference.不会有任何区别，您可以按任何顺序编写，只要您始终使用正确的标签打开和关闭即可。
There won't be any difference, you can write in any order, provided you always open and close with proper tags.
