求解：关于struts1+spring+ibatis整合的问题

Question

struts1+spring+ibatis整合，都配置好了，可是老报错说找不到方法

struts1的配置
[code="java"]
type="org.springframework.web.struts.DelegatingActionProxy" scope="request"
parameter="cmd">





[/code]

是spring的配置

[code="java"]

<bean name="/TimePlan"
    class="com.talkweb.analyseInfo.web.struts.action.TimePlanAction">
        <property name="timePlan">
        <ref bean="proxytimePlanService"/>
    </property>
</bean>

[/code]

action的代码
[code="java"]

public class TimePlanAction extends DispatchAction {

private ITimePlan timePlan;

private TimePlanBean timePlanBean;

protected ActionForward showTimePlan(ActionMapping mapping,
        ActionForm form, HttpServletRequest request,
        HttpServletResponse response) throws Exception {
    System.out.println("---------- show -------------");
    List list = timePlan.getAllTimePlansYear();
    if (list != null) {
        HttpSession session = request.getSession();
        session.setAttribute("timePlanList", list);
        return mapping.findForward("show");
    } else
        return mapping.findForward("error");
}

}
[/code]

web.xml里面配置的是.do结尾的访问action
使用这个访问地址：
http://localhost:8080/analyseInfo/TimePlan.do?cmd=showTimePlan

错误代码：

Answer 1

[code="java"]
java.lang.NoSuchMethodException: com.talkweb.analyseInfo.web.struts.action.TimePlanAction.showTimePlan(org.apache.struts.action.ActionMapping, org.apache.struts.action.ActionForm, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

[/code]
可能是你的Action里的方法签名和它要求的不一致。好好检查一下，或者把struts的Action类里面的execute的方法拷贝过来，再改名字。
