Grails使用kindeditor，支持附件
1、将附件 grails-kindeditor.rar 带目录解压到web-app目录
2、gsp文件代码：
<head>
<script charset="utf-8" src="${resource(dir: 'kindeditor', file: 'kindeditor.js')}"></script>
<script>
KE.show({
id : 'repost_content',
resizeMode : 1,
allowPreviewEmoticons : false,
allowUpload : true,
imageUploadJson : '${createLink(action:'uploadimagejson')}',
attachUploadJson : '${createLink(action:'uploadattachjson')}',
items : [
'fontname', 'fontsize', '|', 'textcolor', 'bgcolor', 'bold', 'italic', 'underline',
'removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist',
'insertunorderedlist', '|', 'emoticons', 'image', 'attach', 'flash', 'link']
});
</script>
</head>
<body>
<g:textArea id="repost_content" name="content" rows="500" cols="400"/>
</body>
3、action代码：
本来是使用对象封装了文件部分属性，这里假定Attach对象有originalName属性，再使用最简单的saveFile,getFile闭包实现
import grails.converters.JSON
def uploadattachjson = {
def text = [error: 1, message: '请选择文件。'] as JSON
if (params.attachFile) {
def attach = savePic(params.attachFile)
text = [error: 0, url: createLink(action: 'downattach', id: attach.id)] as JSON
}
render(contentType: 'text/html; charset=UTF-8', text: text)
}
def downattach = {
def attach = getFile(params.id)
if (attach.exists()) {
response.setContentType("application/octet-stream")
response.setHeader("Content-disposition", "attachment;filename=${getFileName(attach.originalFilename)}" )
response.setContentLength(attach.length() as int)
response.outputStream.write(attach.bytes)
} else {
response.sendError(404)
}
}
def getFileName = {
String agent = request.getHeader('USER-AGENT')
if (null != agent && -1 != agent.indexOf('MSIE')) {
URLEncoder.encode(it, 'UTF8')
} else {
MimeUtility.encodeText(it, 'UTF8', 'B')
}
}
def saveFile = {
def attach = new Attach()
attach.originalName = it.originalFilename
it.transferTo(
new File('c:\attach\'+it.originalFilename)
)
attach.save()
}
def getFile = {
def attach = Attach.get(it)
new File('c:\attach\'+attach.originalName)
}
