file - grails 3.3.9从输入获取文件

Question

我目前在grails 3.3.9上有问题。
这是我的代码:

<g:uploadForm resource="${objetInstance}"role="form" method="POST" class="form-horizontal">

  <g:actionSubmit action="update" class="btn green-meadow"
    value="${message(code: 'enregistrer', 'default': 'Enregistrer')}"/>

               <input type="file" name="myFile" id="myFile"
                               class="form-control"
                               value=""/>

 </g:uploadForm>

在我的Controlle中，我尝试了:

def file = params.myFile

但我的文件为空。

与:

def file = request.getFile('myFile')

Caused by: groovy.lang.MissingMethodException: No signature of method: net.bull.javamelody.JspWrapper$HttpRequestWrapper3.getFile() is applicable for argument types: (java.lang.String) values: [myFile] Possible solutions: getXML(), getPart(java.lang.String), getAt(java.lang.String), getAt(java.lang.String), getLocale(), getJSON() at

向上:
要提供更多信息，这是我的构建gradle。我想我必须添加一个特定的插件来处理文件上传。

我试过了:编译'commons-fileupload:commons-fileupload:1.4'。但仍然存在相同的错误。我真的迷路了。任何的想法？

Answer 1

我能够找到为什么无法上传任何文件的原因:在我的Resources.groovy文件中，我有:

import org.springframework.web.filter.RequestContextFilter

beans{
    ...
    requestContextFilter(RequestContextFilter)
}

此行阻止我上传所有文件。
