我在Play Framework 2.4.10（Java）中开发了一个应用程序，可以在apache-tomcat服务器上运行。
使用PlayFramework的插件创建.war文件。
我创建了一个本地服务器apache-tomcat，并且在部署之后完成演进在所有情况下都按预期发生，没有出现错误日志，只有正常的日志进程。应用程序的所有功能都可以正常运行，没有任何错误，崩溃或滞后。
当我将应用程序部署到Google Cloud Platform（GAE）服务器和其他公司的服务器时，会出现问题。
部署正常进行，但是当用户在某些情况下尝试保存新信息时，服务器不响应POST请求，并且浏览器正在等待来自服务器的响应。当用户多次点击保存按钮时，POST过程会保存数据，通常不会出现错误。
其他功能，如过滤信息，注销，访问注册页面，查询，更改，正常删除工作。只有当我在系统中更新，注册或验证时才会出现错误。
记录屏幕使用HTML PlayFramework本身的模板以及一些Scala语言提示。
这个奇怪的问题偶尔会发生。
我的表格Scala：
@(siteForm: play.data.Form[validators.SiteFormData], paises:Map[String,Boolean])
@import helper._
@import templates.bootstrap._
@views.html.admin.main("Cadastro de Sites") {
<div class="col-md-12">
<div class="page-header header-biogas">
<div class="btn-group btn-breadcrumb pull-right">
<a href="@routes.AdminController.painel()" class="btn btn-default"><i class="fa fa-home"></i></a>
<a href="@routes.SiteController.telaLista()" class="btn btn-default">Sites</a>
<a disabled class="btn btn-default">Cadastro</a>
</div>
<h1 class="font-style"><i class="fa fa-globe" aria-hidden="true"></i> Cadastro de Site</h1>
</div>
</div>
<div class="col-sm-5">
<div class="panel panel-default">
<div class="panel-heading">Cadastro de Sites</div>
<div class="panel-body">
@form(routes.SiteController.inserir(), 'class -> "form-horizontal", 'id -> "siteForm") {
@if(siteForm.hasGlobalErrors) {
<div class="form-group">
<label class="col-sm-3 control-label"></label>
<div class="col-sm-8">
<p class="alert alert-danger text-center">@siteForm.globalError.message</p>
</div>
</div>
}
<!-- titulo -->
@texto(siteForm("titulo"),
label = "Título:",
placeholder = "Insira o título")
@selecao(siteForm("pais"),
label = "País:",
optionMap = paises,
isMultiple = false)
<!-- url -->
@texto(siteForm("url"),
label = "Url:",
placeholder = "Insira o endereço eletrônico")
<div class="form-group">
<div class="col-sm-offset-3 col-sm-12">
<button id="btnSalvar" type="submit" class="btn btn-success">Salvar</button>
<a class="btn btn-default" type="button" href="@routes.SiteController.telaLista()">Cancelar</a>
</div>
</div>
}
</div>
</div>
</div>
}
我的控制器：
@Security.Authenticated(SecuredAdmin.class)
public Result inserir(Long id) {
SiteFormData siteData = (id == 0) ? new SiteFormData() : models.Site.makeSiteFormData(id);
//Resgata os dados do formulario atraves de uma requisicao e realiza a validacao dos campos
Form<SiteFormData> formData = Form.form(SiteFormData.class).bindFromRequest();
//se existir erros nos campos do formulario retorne o SiteFormData com os erros
if (formData.hasErrors()) {
formData.reject("Existem erros no formulário");
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
} else {
try {
//Converte os dados do formularios para uma instancia do Site
Site site = Site.makeInstance(formData.get());
//faz uma busca na base de dados do site
Site siteBusca = Ebean.find(Site.class).where().eq("titulo", formData.data().get("titulo")).findUnique();
if (siteBusca != null) {
formData.reject("O Site com o título'" + siteBusca.getTitulo() + "' já esta Cadastrado!");
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
}
site.setDataCadastro(new Date());
site.save();
tipoMensagem = "success";
mensagem = "Site '" + site.getTitulo() + "' cadastrado com sucesso.";
return created(views.html.mensagens.site.mensagens.render(mensagem,tipoMensagem));
} catch (Exception e) {
Logger.error(e.getMessage());
formData.reject("Erro interno de Sistema. Descrição: " + e);
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
}
}
}
我的路线：
POST /admin/site controllers.SiteController.inserir(id: Long ?= 0)

是否需要配置？
