Java SpringMVC页面HTTP状态400和不正确的URL
我在应用程序中遇到一些问题。我有一张登记表，从管理员那里贴到另一页 此页面显示注册表中的查询结果。在结果页面上，我选择了一条记录，它返回给我 将数据发送到注册页面。用户应该能够在记录返回后更新记录，或者再次执行查询 我遇到的问题是，当用户在注册表上执行一个查询时，他们将被发布到结果页面 将显示结果页面，但url不会更改。注册url为http://localhost:8084/crimeTrack/citizen_registration.htm 当通过单击“查询”按钮发布到结果页面时，url仍然为空http://localhost:8084/crimeTrack/citizen_registration.htm 在结果页面上单击/选择包含多条记录的记录时，用户将使用 选中的记录，并显示该记录供用户现在再次执行更新或查询，url为http://localhost:8084/crimeTrack/getCitizen/1985121244.htm 用户现在已进入注册页面 如果我再次单击查询/更新，我将收到一个HTTP 400错误，并且url正在读取http://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm/ 并且这不是控制器中的有效URL映射。我认为url应该是http://localhost:8084/crimeTrack/citizen_registration.htm 当注册页面打开时 请求。我不确定结果页面上的帖子何时会将用户带回注册页面，url应该是什么http://localhost:8084/crimeTrack/getCitizen/1985121244.htm 所附号码为公民号码。在“是我的代码”下，我不确定我是否正确地执行了这些调用，我还想对我得到的结果进行解释 解决遇到的问题 使用jquery提交页面： 这是注册页面的一个示例，所有其他页面都遵循相同的模式 JScript citizen_registration.jspJava SpringMVC页面HTTP状态400和不正确的URL,java,spring,spring-mvc,url-routing,Java,Spring,Spring Mvc,Url Routing,我在应用程序中遇到一些问题。我有一张登记表，从管理员那里贴到另一页 此页面显示注册表中的查询结果。在结果页面上，我选择了一条记录，它返回给我 将数据发送到注册页面。用户应该能够在记录返回后更新记录，或者再次执行查询 我遇到的问题是，当用户在注册表上执行一个查询时，他们将被发布到结果页面 将显示结果页面，但url不会更改。注册url为http://localhost:8084/crimeTrack/citizen_registration.htm 当通过单击“查询”按钮发布到结果页面时，url仍然
问题是当你说action=citizen\u registration.htm时，你在这里使用的是相对路径 换成
document.getElementById("citizenRegistration").action="/crimeTrack/citizen_registration.htm";
1将输入类型更改为button而不是submit，并添加一个onclick事件，该事件将调用传递要调用的操作的submitPage函数
<input class="button" id="save" type="button" name="user_request" value="Save" onclick="submitPage('citizen_registration.htm');"/>
<input class="button" id="update" type="button" name="user_request" value="Update" onclick="submitPage('citizen_registration.htm');"/>
<input class="button" id="query" type="button" name="user_request" value="Query" onclick="submitPage('citizen_list.htm');"/>

这并没有以任何方式解决问题，如果表单在没有js的情况下提交，那么问题仍然存在there@PathVariable概念可以是您需求的解决方案尝试修改您的请求映射，如下所示@RequestMappingvalue=getCitizen.htm/{socialSecurityNumber}，method=RequestMethod.Post我正在使getCitizen url映射与PathVariable一起工作问题是当我在注册页面上时，我执行一个查询，当我在该页面上单击结果时，我被带到结果列表页面。然后它会将我带回注册页面，这样我现在就可以看到一条记录。现在的问题是，如果单击“更新”或“查询”，我将收到Http 404错误，这是一个错误的url idk getCitizen如何附加到citizen_注册，并且控制器中没有任何内容与该url localhost:8084/crimeTrack/getCitizen/citizen_注册.htm映射或找到。控制器应查找citizen_注册映射，执行将用户重定向到结果列表页面的查询，或更新记录并将用户返回到同一页面。另外，重定向对jsp文件夹中的任何jsp页面都不起作用。我正在使用jscript提交页面。我认为没有任何必要在表单标签中包含该操作？我遇到的问题是，当我在注册表上单击“查询”时，我被带到citizenList.htm，很好，我不使用重定向来访问此页面，我做了一个简单的操作返回新模型并查看公民列表；页面返回结果正常，但是url没有改变，它保持不变。啊，我明白了，您正在返回新的ModelAndViewcitizenList，您希望看到url更改为类似localhost:8084/crimeTrack/citizenList.htm的内容。对吗？如果是这种情况，您需要一个单独的控制器方法来检索映射到您希望看到的URL的citizenList。现在，handleRequest方法中的所有内容都已映射到citizen_registration.htm。您需要@RequestMapping/citizenList.htm public model和view getCitizenList…是的，这是正确的，但是我正在同一表单上执行操作，即在注册表上，我有一个查询按钮，页面已经映射到citizen\u注册请求映射。其他页面功能（如保存和更新）都发生在citizen_注册请求映射中。不同之处在于查询函数会将您带到另一个视图，但
保存和更新没有。我已经用一个示例更新了答案，根据单击的按钮设置操作。基本步骤是1将submit按钮更改为常规按钮，并添加一个onclick函数，该函数将调用submitPage传递要调用的操作，2更新submitPage函数以指定发布前的操作，3更新控制器以具有2种方法，一个用于映射到citizen_registration.htm的保存/更新，另一个用于映射到citizen_list.htm的查询。
