我正在尝试使用renderpdf grails插件渲染PDF, 但他们的文件很短。
我在我的gsp视图/文件中创建了一个按钮
<button type="button">PDF Me!</button>
和
ByteArrayOutputStream bytes = pdfRenderingService.render(template: "/pdfs/report", model: [data: data])
在视图中绑定图像
<rendering:inlinePng bytes="${imageBytes}" class="some-class" />
模型数据是domainInstance,如何将该按钮与此renderpdf连接?
可能是我应该更多地指定我的代码
def invoice ={
def vermittlungInstance = Vermittlung.get(params.id)
def aa = vermittlungInstance.lieferungen.id
def lieferungInstance = Lieferung.get(aa)
def bb = lieferungInstance.packete.id // .id
def packetInstance = Packet.findAllByIdInList(bb)
if (!vermittlungInstance & !lieferungInstance) {
flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'vermittlung.label', default: 'Vermittlung'), params.id])}"
redirect(action: "list")
}
else {
if(vermittlungInstance.rechnungen.id!=null || vermittlungInstance.lieferungen.id!=null || lieferungInstance.packete.id!=null ){
def a = vermittlungInstance.rechnungen.id
def rechnungList = Rechnung.findById(a)
def b = vermittlungInstance.lieferungen.id
def lieferungList = Lieferung.findById(b)
def c = lieferungInstance.packete.id
//println c
def packetList = Packet.findAllByIdInList(c)//findById(c)
def d = packetInstance.artikel.id//id
def artikelList = Artikel.findAllByIdInList(d)//findById(d)
def e = lieferungInstance.adressen.id
def adresseList = Adresse.findById(e)
[vermittlungInstance: vermittlungInstance,
rechnungInstanceList:rechnungList,
lieferungInstanceList:lieferungList,
packetInstanceList: packetList,
artikelInstanceList: artikelList,
adresseInstanceList: adresseList
]
//System.out.println(c)
}
else{
def rechnungList = Rechnung.all
def lieferungList = Lieferung.all
def packetList = Packet.all
def artikelList = Artikel.all
def adresseList = Adresse.all
[vermittlungInstance: vermittlungInstance,
rechnungInstanceList:rechnungList,
lieferungInstanceList:lieferungList,
packetInstanceList: packetList,
artikelInstanceList: artikelList,
adresseInstanceList: adresseList
]
}
}
}
这是我在控制器中的def,我试图把这个renderpdf放在很多地方,但是它不会渲染页面,实际上我在html(浏览器)中改变了一些值,所以它应该用html渲染。 / p>
控制器似乎是renderpdf的错误位置,但.gsp没有渲染函数
感谢

添加新操作,生成发票的pdf版本并从您的视图中链接它们。
这是您的链接:
<g:link action="downloadInvoice" id="${yourInvoiceID}">Download invoice</g:link>
在你的控制中添加以下内容:
def downloadInvoice = {
def invoice = Invoice.get(params.id) //replace with your logic
renderPdf(template: '/templates/pdf/invoice', model: [invoice: invoice], filename: "yourTitle")
}
您的发票模板是一个简单的gsp视图,您可以在其中放置所有HTML(包括图像)和CSS:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Invoice</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" href="${resource(dir:'css',file:'your.css')}" />
</head>
<body>
<img src="${resource(dir:'images',file:'invoiceLogo.png')}" />
<h1>Invoice: ${invoice.id}</h1>
.
.
.
</body>
</html>
希望这个例子有帮助!

如何将unicode字体添加到此插件? unicode字符不会在呈现的pdf中显示。生成的pdf包含空格代替unicode字符,尽管它们显示在其他gsp页面中。后来我尝试了下面的CSS。但没有奏效。
@font-face {
font-family: 'Ubuntu';
font-style: normal;
font-weight: 400;
src:url(http://themes.googleusercontent.com/static/fonts/ubuntu/v4/_xyN3apAT_yRRDeqB3sPRg.woff) format('woff');
-fs-pdf-font-embed: embed;
-fs-pdf-font-encoding: UTF-8;
}
body pre{
font-size: 14px;
font-family: 'Ubuntu', Helvetica, Arial, sans-serif;
}
谢谢,
