Question

我成功将csv文件上传到grails并列出了上传的文件。但是，如何在用户界面中通过分页，搜索/过滤和列排序查看上传的文件？

我的上传功能

def upload() { 
    def file = request.getFile('file')
        if(file.empty) {
        flash.message = "File cannot be empty"
        render(view: 'create')
} else {
def documentInstance = new Document()
documentInstance.filename = file.originalFilename
documentInstance.type = file.contentType

documentInstance.fullPath = grailsApplication.config.uploadFolder +file.originalFilename
file.transferTo(new File(documentInstance.fullPath))
documentInstance.save()

我的upload.gsp

<html>
<head>
    <meta name="layout" content="main">
    <title>Upload New Document</title>
</head>
<body>
    <div class="nav" role="navigation">
        <ul><li><g:link class="list" action="list">Document List</g:link></li></ul>
    </div>
    <div class="content scaffold-create" role="main">
        <h1>Upload New Document</h1>
        <g:if test="${flash.message}"><div class="message" role="status">${flash.message}</div></g:if>
        <g:uploadForm action="upload">
            <fieldset class="form">
                <input type="file" name="file" />
            </fieldset>
            <fieldset class="buttons">
                <g:submitButton name="upload" class="save" value="Upload" />
            </fieldset>
        </g:uploadForm>
    </div>
</body>

现在，如何查看具有上述规范的CSV文件的内容？
