我的处理方式如下
我把SAIFSpringPlugin反编译，将saif-sping.jar中的那个class删除了
然后自己在src下面建个相同的包，下面建个同名的java类。
这样，在struts1.3.10 + spring3.1.0环境下也没问题了。package net.sf.struts.saif;import javax.servlet.ServletException;import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.config.ControllerConfig;
import org.apache.struts.config.ModuleConfig;/**
