CharacterEncodingFilter编码过滤器

SpringMVC通过配置CharacterEncodingFilter编码过滤器来解决项目中的乱码问题，只需要在web.xml中配置CharacterEncodingFilter即可。

<!-- 配置编码过滤器 -->
  <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>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
