＆＃34;为HTTP路径映射的模糊处理程序方法＆＃34;第三次提交表单时，Spring MVC中的异常

我有一个带有复选框的表格＆＃34; genererCle＆＃34;和清单＆＃34;干部＆＃34;。当用户在列表中选择另一个值时，或者如果他选中/取消选中该复选框，则会有服务器调用。它在2个文件之间定义：topologie.html和topologie.js：

<form action="#" th:action="@{/bus/topologie}"
            th:object="${topologie}" method="post" class="form-horizontal">
...
    <div class="checkbox">
        <input type="checkbox" th:field="*{genererCle}"
            th:value="${genererCle}" class="genererCle" />
    </div>
    <select th:field="*{versionCadre}" class="form-control">
        <option th:each="versionCadre : ${allVersionCadre}"
            th:value="${versionCadre}" th:text="${versionCadre}">...</option>
    </select>
    <button type="submit" hidden="hidden" id="updateNatures"
        name="updateNatures"></button> 
    <button type="submit" hidden="hidden" id="genererCle"
        name="genererCle"></button>

.js：

$(document).ready(function() {
...
    $("#versionCadre").change(function() {
        $("#updateNatures").click();
    });
    $(".genererCle").change(function() {
        $("#genererCle").click();
    });
...
}

在服务器端，它使用了一个控制器TopologieController，我在其中定义了两个方法：

@Controller
@SessionAttributes(value = "topologie", types = { Topologie.class })
@RequestMapping("/bus/topologie")
public class TopologieController {
    private static final String VIEW_TOPOLOGIE = "topologie";

    @RequestMapping(method = RequestMethod.POST, params = { "genererCle" })
    public String genererCle(final Topologie topologie, final Model model)
        throws IOException {
        cadreService.genererCle(topologie);
        return VIEW_TOPOLOGIE;
    }

    @RequestMapping(method = RequestMethod.POST, params = { "updateNatures" })
    public String updateNatures(final Topologie topologie, final Model model)
        throws IOException {
        cadreService.updateConfig(topologie);
        return VIEW_TOPOLOGIE;
    }

    @RequestMapping(method = RequestMethod.POST)
    public String validForm(final Topologie topologie,
        final BindingResult result, RedirectAttributes attr,
        HttpSession session) {

        if (result.hasErrors()) {
            logger.info("Form has errors ! : {}", result);
            return VIEW_TOPOLOGIE;
        }

        attr.addFlashAttribute("topologie", topologie);
        return "redirect:/bus/topologie/recap";
    }

每次提交都可以独立完成，但是当我连续3次提交时，我有一个例外。提交序列：用户更改列表中的值＆＃34; versionCadre＆＃34;然后他检查＆＃34; genererCle＆＃34;复选框，最后他在列表中进行了另一项更改＆＃34; versionCadre＆＃34;。

我认为param命名（java方面）很清楚。但是当我在这里阅读类似问题时，我明白这还不够。

我尝试使用PR（G）模式更改此内容：

@RequestMapping(method = RequestMethod.POST, params = { "genererCle" })
public String genererCle(final Topologie topologie, final Model model)
    throws IOException {
    cadreService.genererCle(topologie);
    return VIEW_TOPOLOGIE;
}

在此：

@RequestMapping(method = RequestMethod.POST, params = { "genererCle" })
public String genererClePost(final Topologie topologie, final Model model)
        throws IOException {
    cadreService.genererCle(topologie);
    return "redirect:/bus/topologie";
}

但它没有更好的效果。

1 个答案:

答案 0 :(得分：1)

I had the similar error.

In the controller I had 2 methods like these.

  1. @RequestMapping(value = { "/{name}" }, method = RequestMethod.GET) void foo1(@PathVariable("name") final String name)

  2. @RequestMapping(value = { "/{email}" }, method = RequestMethod.GET) void getTemplateVersionsBySenderForClient(@PathVariable("email") final String email, @RequestParam(value = "timestamp", required = true) final long timestamp)

then I changed the request mapping part for the second method: @RequestMapping(value = { "/trigger/{email}" }, method = RequestMethod.GET)

And the error was resolved.

Concept was, from the front end side Spring mvc was not able to decide for which method needs to be called. As both {name} and {email} in the requestMapping were variables. http://localhost:8000/Project/{email} and http://localhost:8000/Project/{name} both email and name can take similar values(not validating)

Hope it helps
