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:

在您的 web.xml 中,您有 *.html 扩展名的映射,同时尝试访问映射为 .jsp 的页面。

您需要将映射更改为

@RequestMapping(value = "TimeTracking")

并将html表单的动作修复为action ="TimeTracking.html"

另外,如果您是 Spring MVC 新手并想使用它的功能,请查看 Spring MVC Showcase demo http://blog.springsource.org/2010/07/22/spring-mvc-3-showcase/

将 spring servlet 的 web.xml url-pattern 更改为 * 或将操作名称更改为 TimeTracking.html 并将 requestmapping 的 value 属性更改为 /TimeTracking.html。从jsp页面我了解到我们使用输入类型作为按钮而不是提交并且按钮上也有一个事件,尝试更改输入类型以提交操作名称和requestmapping的值属性更改为TimeTracking.html .

您的网址格式是 *.html。因此,将您的操作更改为TimeTracking.html。并将您的请求映射更改为/TimeTracking.html
