@WebFilter的annotation如何设置可以对应web.xml中filter的先后顺序问题?

Question

对于同一个servlet的多个filter,在web.xml里面注册先后就会实现先后的过滤作用，那么如果使用annotation，对应的属性是什么呢？

精确控制还是需要web.xml，不过只需要配置<filter-mapping>
举个例子:

@WebFilter(filterName="filter1", urlPatterns="/url1/*")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2", urlPatterns="/url2/*")
public class Filter2 implements Filter {}

web.xml里:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern />
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern />
</filter-mapping>
