java – 如何实现我的Web应用程序的Affiliate链接？

是的,我同意@krassib和@TomR – 使用queryString参数,然后你可以编写一个servlet过滤器来检查特定的参数,并增加该联盟的计数.使用servlet过滤器还可以为您提供额外的好处,即跟踪每个联盟会员的单个链接的数量.

您执行以下操作：

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class AffiliateTrackingFilter implements Filter {
    private AffiliateTrackingService affiliateTrackingService = null;

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(ServletRequest rq,ServletResponse rs,FilterChain chain) throws IOException,ServletException {
        String affililateId = rq.getParameter("affiliateId");
        affiliateTrackingService.incrementAffiliateHit(affililateId);
        chain.doFilter();
    }

    @Override
    public void init(FilterConfig fc) throws ServletException {
        affiliateTrackingService = new AffiliateTrackingService();
    }
}

然后在web.xml中添加这样的内容：

<filter>
    <filter-name>AffiliateTrackingFilter</filter-name>
    <filter-class>com.example.AffiliateTrackingFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>AffiliateTrackingFilter</filter-name>
    <servlet-name>MyMainServlet</servlet-name>
</filter-mapping>

并为所有servlet提供过滤器映射.
