Question

我正在尝试实施此系统：http://en.pudn.com/downloads108/sourcecode/java/jsp/detail446536_en.html

但登录时遇到404错误。我输入url：localhost：8080 / voting /。输入用户名和密码后，我正确地提交表格并得到404错误：

http://localhost:8080/voting/login.html?method=login


HTTP Status 404 -

type Status report

message

description The requested resource () is not available.

Apache Tomcat/7.0.29

我正确配置了数据库。我不明白是什么问题？拜托，有人可以帮忙吗？

有struts-config.xml代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

来自login.jsp的代码：

<form id="loginForm" name="loginForm" method="post" action="<%=request.getContextPath()%>/login.html?method=login">
            <table width="240" height="165" border="0" cellpadding="0" cellspacing="0">

                <td align="center" valign="middle"><table width="230" border="0" align="center" cellpadding="5" cellspacing="0" class="p1">
                  <tr>
                    <td align="right">&nbsp;</td>
                    <td>&nbsp;</td>
                  </tr>
                  <tr>
                    <td width="45" align="right">ID:</td>
                    <td width="165"><input class="inputPSW"  name="account" id="account" type="text" maxlength="16"></td>
                  </tr>
                  <tr>
                    <td align="right">Password:</td>
                    <td><input class="inputPSW" id="pwd" name="pwd"  type="password"  maxlength="16"></td>
                  </tr>
                  <tr>
                    <td colspan="2" align="center">
                    <img onClick="return CheckForm();"  src="<%=request.getContextPath()%>/images/login/bn_login1.gif" id="Image1" onMouseOver="MM_swapImage('Image1','','<%=request.getContextPath()%>/images/login/bn_login2.gif',1)" onMouseOut="MM_swapImgRestore()">&nbsp; 
                    <img onClick="return resetBt();" src="<%=request.getContextPath()%>/images/login/bn_reset1.gif" id="Image2" onMouseOver="MM_swapImage('Image2','','<%=request.getContextPath()%>/images/login/bn_reset2.gif',1)" onMouseOut="MM_swapImgRestore()">
                      <input name="CheckLogin" type="hidden" id="CheckLogin" value="True">                        </td>
                  </tr>
                </table></td>
              </tr>
            </table>
          </form>

这是我的web.xml文件：

我在哪里做错了？

Answer 1

除非您实际将操作servlet映射到*.html，否则表单标记中的"action"属性几乎肯定是错误的。如果您正在使用调度操作，则操作应指向struts-config文件中配置的操作。

除此之外，为什么你不使用任何Struts 1表单标签？他们让事情变得更容易。另外，我建议将您的JSP文件放在WEB-INF下，以便客户端无法直接访问它们。

此外，这与Spring MVC，Hibernate或Struts 2无关。
