Web.XML加载Spring配置文件的两种方式

1.xml文件放在WEB-INF下

如加载下面的dispatcher-servlet.xml文件，在web.xml中添加以下配置：

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

确保servlet-name与加在文件名称为*-servlet.xml即可。

2.指明加载路径

在web.xml中加入以下配置：

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:META-INF/common-frame/common-frame*.xml</param-value>
</context-param>
<listener>
		<!-- listener-class>org.springframework.web.context.ContextLoaderListener</listener-class -->
		<listener-class>cots.web.common.listener.SpringContextLoaderListener</listener-class>
</listener>

也可放在：

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>路径</param-value>
		</init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
