Grails:从GSP生成PDF [英] Grails : Generating PDF from GSP
问题描述
我的GSP网页有多个表格,还有其他一些HTML元素,例如输入文字栏位和标题< h1> < h2>
文本。
我想要在生成的文本中捕获所有这些信息。
到目前为止,我所看到的例子只能用于生成一个表格。
有没有一种快速的方法可以从已经在GSP中填充的所有数据生成PDF?
I使用Export插件。
compile':export:1.6'
pre>
下面是我到目前为止试过的示例代码。
它绘制了一个带有标题的表格,并且没有数据在行中。
def myPDFexport(){
String userNumber = params.UserInfoInstance;
UserInfo userObj = UserInfo.findByNumber(userNumber);
params.format =pdf;
params.extension =pdf
列表字段= [用户名,用户名,用户密码]
地图标签= [用户ID:用户ID,用户名:用户名,userPW:用户密码]
if(params?.format& amp; amp; params.format!=html){
response.contentType = grailsApplication .config.grails.mime.types [params.format]
response.setHeader(Content-disposition,attachment; filename = $ {woNumber}。$ {params.extension})
exportService .export(params.format,response.outputStream,userObj.list(params),fields,labels,[:],[:])
}
}
由于我是Grails的新手,并且也没有以前的PDF生成经验,所以我几乎失去了这一点。
如果可能,请为我提供一些示例代码。
解决方案有很多解决方案来创建PDF。
作为第一个简单的方法,您应该查看 Grails渲染插件。您可以使用任何视图或模板生成pdf(或图像) 。
将插件添加到您的项目后,您可以将如下操作添加到您的控制器中:
def createPdfReport = {
renderPdf(template:'/ templates / pdf / yourtemplate',model:yourmodel,filename:yourTitle)
}
它将使用指定的模板生成pdf并将其作为响应发送给客户端。
有关更多信息,请参阅插件文档。
My GSP page has multiple tables and also some other HTML elements like input text fields and header
<h1> <h2>
texts.I want all this info to be captured in the generated text.
So far the examples i have seen is only good for generating one table.
Is there a quick way of generating the PDF from all the data that's already populated in GSP?
I am using the Export plugin.
compile ':export:1.6'
And below is the sample code i tried so far.
It draws one table with headers and no data in the rows.
def myPDFexport () { String userNumber = params.UserInfoInstance; UserInfo userObj = UserInfo.findByNumber(userNumber); params.format = "pdf"; params.extension = "pdf" List fields = ["User ID", "User Name", "User Password"] Map labels = [userID: "User ID", userName: "User Name", userPW: "User Password"] if(params?.format && params.format != "html"){ response.contentType = grailsApplication.config.grails.mime.types[params.format] response.setHeader("Content-disposition", "attachment; filename=${woNumber}.${params.extension}") exportService.export(params.format, response.outputStream, userObj.list(params), fields, labels, [:], [:]) } }
I am almost lost on this as i am new to Grails and also have no previous experience with PDF generation.
If possible, please provide me with some sample code.
解决方案There are a lot of solutions to create PDFs.
As a first and easy approach you should have a look at the Grails rendering plugin.
You could use any view or template to generate a pdf (or image).
After adding the plugin to your project you could add an action like this to your controller:
def createPdfReport = { renderPdf(template: '/templates/pdf/yourtemplate', model: yourmodel, filename: "yourTitle") }
It will use the specified template to generate a pdf and send it as response to the client.
For further information have a look at the plugin documentation.
