当我尝试使用提交按钮在 jsp 页面中调用我的表单发布时，页面似乎正在重新加载，但我的 @Requestmapping 方法中没有发生任何事情被调用。
这是 Spring 注释的 java 方法：
@RequestMapping(value = "/TimeTracking.jsp", method = RequestMethod.POST)
public String changeTheWeek(HttpServletRequest request) {
if ("Previous Week".equals(request.getParameter("changeWeek"))) {
this.subtractOneWeek();
} if ("Next Week".equals(request.getParameter("changeWeek")))
{
this.addOneWeek();
}
return "redirect:TimeTracking.jsp";
}
这是jsp页面的表单：
<form name="ChangeWeek" method="POST" action="TimeTracking.jsp">
<span> <input name="changeWeek" type="submit" value="Previous Week"/> Hours for the week of
<%=currentWeek.firstDayOfThisWeek()%> until <%=currentWeek.lastDayOfThisWeek()%>
<input name="changeWeek" type="submit" value="Next Week"/>
</span>
</form>
这是我的 spring-servlet.xml 文件：
