web.xml配置引入2个spring配置文件

问题：IOException parsing XML document from ServletContext resource [/WEB-INF/application.xml

我把web.xml中的全局的

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
    </context-param>
注释以后报出以上的错误了。
注释去掉以后不会报错了。我很纳闷的是springMVC的servlet上配置了contextConfigLocation，但是在web.xml的全局还要再配置一次。

	</welcome-file-list>
</web-app>

 

总结：

web.xml中2个地方需要配置spring配置。

第一个是

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
</context-param>

 ApplicationContext.xml内容为空，否则spring bean将实例化2个。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:mvc="http://www.springframework.org/schema/mvc"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context.xsd
      http://www.springframework.org/schema/mvc
  	  http://www.springframework.org/schema/mvc/spring-mvc.xsd">
</beans>

 

第二个是spring-mvc配置，这里才实例化bean对象。

<servlet>
		<servlet-name>spring-mvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring-mvc</servlet-name>
		<url-pattern>/cps/*</url-pattern>
	</servlet-mapping>
