Java 通过Spring使用@Requestmapping的.jsp页面发布表单不起作用

java spring jsp spring-mvc

Java 通过Spring使用@Requestmapping的.jsp页面发布表单不起作用,java,spring,jsp,spring-mvc,Java,Spring,Jsp,Spring Mvc,当我尝试在jsp页面中使用submit按钮调用表单post时，页面似乎正在重新加载，但@Requestmapping方法中发生的任何事情都不会被调用 这是Spring注释的java方法： @RequestMapping(value = "/TimeTracking.jsp", method = RequestMethod.POST) public String changeTheWeek(HttpServletRequest request) { if ("Previou

当我尝试在jsp页面中使用submit按钮调用表单post时，页面似乎正在重新加载，但@Requestmapping方法中发生的任何事情都不会被调用

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";
    }
以下是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>
最后，这里是表单所在的full-TimeTracking.jsp页面：

在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

@RequestMappingvalue=TimeTracking

并将html表单的操作修复为action=TimeTracking.html

另外，如果您是Spring MVC新手，并且希望使用其功能，请在您的web.xml中检查Spring MVC Showcase demo，您有*.html扩展名的映射，同时尝试访问映射为.jsp的页面

将SpringServlet的web.xml url模式更改为*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，按钮上也有一个事件，尝试更改要提交的输入类型，操作名称和requestmapping的值属性更改为TimeTracking.html。

所以我做了这些更改，但仍然不起作用。当我单击submit按钮时，它会给我一个404错误RequestURI=/SpaceTime/jsp pages/TimeTracking.html，但即使我更改了请求映射方法，使其根本不返回时间跟踪页面，它仍然会说它无法解析时间跟踪页面！它进入你的控制器方法了吗？你可以在调试模式下设置断点。我试过了，但它似乎根本没有进入我的控制器方法。所以一定是我的jsp表单写得不正确？最简单的方法是用get替换posr方法，并尝试从浏览器打开页面以查看其映射是否正确-您还可以将org.springframework命名空间的记录器配置为调试级别，最硬的方法是在spring DispatcherServlet Classic中设置断点。您表单中的地址似乎应该以..作为前缀。\n换句话说，您根本不应该通过jsp pages子路径访问spring控制的页面！所以我做了这些改变，但仍然不起作用。当我单击submit按钮时，它会给我一个404错误RequestURI=/SpaceTime/jsp pages/TimeTracking.html，但即使我更改了请求映射方法，使其根本不返回时间跟踪页面，它仍然会说它无法解析时间跟踪页面！它进入你的控制器方法了吗？你可以在调试模式下设置断点。我试过了，但它似乎根本没有进入我的控制器方法。所以一定是我的jsp表单写得不正确？最简单的方法是用get替换posr方法，并尝试从浏览器打开页面以查看其映射是否正确-您还可以将org.springframework命名空间的记录器配置为调试级别，最硬的方法是在spring DispatcherServlet Classic中设置断点。您表单中的地址似乎应该以..作为前缀。\n换句话说，您根本不应该通过jsp pages子路径访问spring控制的页面！
