Spring MVC 乱码问题

在web.xml文件中配置SpringMvc编码过滤器的编码方式，设置初始编码方式

<!-- SpringMVC 提供的过滤器 
注意 url-pattern 为 /*，过滤所有请求（包括 jsp ）；如果设置为 /，访问 jsp 就不会经过过滤器了！
-->
<filter>
        <filter-name>EnCodingFiliter</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>
    </filter>
    <filter-mapping>
        <filter-name>EnCodingFiliter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 

 <filter>
        <filter-name>EnCodingFiliter</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>
        <!--设置强制编码格式，防止还出现乱码-->
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>EnCodingFiliter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
