pdf - Grails 渲染插件在 Grails3.2.4 下不起作用？

转载作者：行者123 更新时间：2023-12-01 14:56:17

我想将 View 渲染为 pdf 并尝试使用 Grails 渲染插件 2.0.3

我尝试从最简单的 gsp 文件开始:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<!--
  To change this license header, choose License Headers in Project Properties.
  To change this template file, choose Tools | Templates
  and open the template in the editor.
-->

<%@ page contentType="text/html;charset=UTF-8" %>

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Sample title</title>
    </head>
    <body>
        <h1>Sample line</h1>
    </body>
</html>

在 Controller 中:

    def report() {
        def OfferHeader oh = OfferHeader.get(15)
        println(">>> Offerheader: "+oh.sawMill)
//        render(template: "/offerHeader/Test")
        renderPdf(template: "/offerHeader/Test",  filename: "offertrapport.pdf")

    }

最后是:

2017-04-14 11:26:55.989 ERROR --- [nio-8080-exec-6] o.g.web.errors.GrailsExceptionResolver   : NullPointerException occurred when processing request: [GET] /offerHeader/report/15

我错过了什么？或者它不应该与这个版本的 grails (3.2.4) 一起工作？

也许有更好的插件可以使用？

最佳答案

首先在build.gradle中添加如下依赖:

dependencies {
    ...
    runtime "org.springframework:spring-test:4.2.1.RELEASE"
}

然后假设我们要在单击链接时呈现 pdf，所以在 gsp 中:

<g:link action="report" params='[offerId: "${offer.id}"]'>To PDF</g:link>

然后在 Controller 中:

def report() {
    def offer = Offer.get( params.offerId )
    renderPdf(template: "offerpdf", model: [offer: offer],  filename: "offer.pdf")
}

在您的报价 View 目录中，您将有一个名为 _offerpdf.gsp

的模板 gsp

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
    <title>Offer</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>Offer: ${offer.id}</h1>
</body>
</html>
