在搭建springmvc框架时，需要配置web.xml中的字符表编码过滤器  
配置如下

<filter>
    	<filter-name>CharacterEncodingFilter</filter-name>
    	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    	<init-param>
    		<param-name>encoding</param-name>
    		<param-value>utf-8</param-value>
    	</init-param>
    	<init-param>
    		<param-name>forceRequestEncoding</param-name>
    		<param-value>true</param-value>
    	</init-param>
    	<init-param>
    		<param-name>forceResponseEncoding</param-name>
    		<param-value>true</param-value>
    	</init-param>
    	<filter-mapping>
    		<filter-name>CharacterEncodingFilter</filter-name>
    		<filter-pattern>/*</filter-pattern>
    	</filter-mapping>
    </filter>

结果报错其中的

CharacterEncodingFilter /\* 报错‘cvc-complex-type.2.4.a: Invalid content was found starting with element 'filter-mapping'. One of '\{"http://java.sun.com/xml/ns/javaee":init-param\}' is expected’

后研究得知，错误原因为  
根元素中的模式文件不对，  
javaee只支持单个的config不支持filter-mapping，要换成 j2ee

即将模式文件

“http://java.sun.com/xml/ns/javaee”  
改成  
“http://java.sun.com/xml/ns/j2ee”

测试发现不报错。
