servlet3.0 @webfilter 过滤顺序

    Servlet3.0之前Filter过滤的顺序是由用户在web.xml中配置的顺序决定的，如下会先执行encodingFilter,再执行filter1.

  <filter>  <display-name>encodingFilter</display-name>  <filter-name>EncodingFilter</filter-name>  <filter-class>com.saber.domain.EncodingFilter</filter-class>  </filter>    <filter-mapping>    <filter-name>encodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>  <filter>  <display-name>filter1</display-name>  <filter-name>filter1</filter-name>  <filter-class>com.saber.domain.Filter1</filter-class>  </filter>    <filter-mapping>    <filter-name><span style="font-family: Arial, Helvetica, sans-serif;">filter1</span><span style="font-family: Arial, Helvetica, sans-serif;"></filter-name></span>    <url-pattern>/*</url-pattern>  </filter-mapping>

在3.0之后新增@WebFilter注解，当使用注解配置多个Filter时，用户无法控制其执行顺序，此时Filter过滤的顺序是按照Filter的类名来控制的，按自然排序的规则。
