springMvc配置文件

虽然一直用springMvc,但还是有些基本知识点有误区。

springmvc为什么有多个配置文件，为什么这些配置文件不能写到同一个文件里面，如果你懂了肯定就知道，所有文件写一个一个配置文件里面不好维护，模块化的配置导致不同的配置文件是趋势。

我们来看web.xml 里面

我们都知道listener是spring的入口，

springServlet是用来获取springmvc controller里面的信息 。

<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 本地用的spring配置项 -->
<param-value>classpath:/youdao/spring-context*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>springMvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 本地用的spring配置项-->
<param-value>classpath:/youdao/youdaospring-dispatcherservlet.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>/yd/*</url-pattern>
</servlet-mapping>

如果在web.xml中不写任何参数配置信息，默认的路径是”/WEB-INF/applicationContext.xml，在WEB-INF目录下创建的xml文件的名称必须是applicationContext.xml。如果是要自定义文件名可以在web.xml里加入contextConfigLocation这个context参数：在 里指定相应的xml文件名，如果有多个xml文件，可以写在一起并一“,”号分隔。

如果我们没有在web.xml里面配置springServlet的具体文件地址那么

默认为WEB-INF目录下，名称为[]-servlet.xml，如spring-servlet.xml

我们来看一个完整的

<!-- Spring MVC配置 -->
<!-- ====================================== -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>  默认
</init-param>
-->
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

<!-- Spring配置 -->
<!-- ====================================== -->
<listener>
<listenerclass>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/applicationContext.xml</param-value>
</context-param>

spring.servlet.xml里面主要扫描的是controller的信息，然后回设定一个返回格式、视图文件解析、视图文件解析

<context:component-scan base-package="com.thinkgem.jeesite" use-default-filters="false"><!-- base-package 如果多个，用“,”分隔 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

而application.xml里面配置有 数据库信息、事务、开启注解啊 等等。加载的这些都是spring上下文用来的信息

所以我们千万不要把application.xml 和spring-servlet.xml里面内容弄混淆 ，也不要把他们加载顺序弄混淆。

application.xml是上下文，配置在listener的参数

spring-servlet.xml 是servlet的参数

最后来个完整的jeesite的配置文件。

spring-context.xml(等于application.xml)
