Java call wkhtmltopdf generate PDF file, beautiful, convenient

Recent projects need to export Enterprise Risk report, file format for pdf, so searched a large number of articles are what Jasper report,IText ,flying Sauser , have tried again, Feeling is not the effect I want,

Need to adjust their own a lot of things, style, font and so on, good trouble, after all, Bo master so lazy people, haha. -------Jstarseven

Anyway

Java generated PDF file, a lot of ways, the above mentioned in which ways specific can refer to this article < explain very detailed >:http://blog.csdn.net/ouyhong123/article/details/26401967

This article says the blogger thinks it is better to use a tool: Wkhtmltopdf

Wkhtmltopdf is a tool developed using the WebKit Web rendering engine to convert HTML into PDF, which can be integrated with a variety of scripting languages to transform documents, easy to use, at least my PDF is not super complex, haha

First Test:

Enter CMD,CD E:\software\wkhtmltopdf\bin

Execute Wkhtmltopdf.exe http://www.jstarseven.com/e:\data\pdf\jstarseven.pdf

Open E:\data\pdf\jstarseven.pdf look at the effect can also, at least not very troublesome.

Then it is to write a small program, encapsulate it, tune the DOS command.

The blogger's idea is to prepare an HTML template to generate the PDF, the data is all placeholder placeholder, when the need to generate a PDF, the first to write data to the file, and then call Wkhtmltopdf to generate a PDF file.

The part of the document does not say, look directly at the PDF part of it, the code is very simple.

Code: Htmltopdf.java

Effect Test Chart:

Finally reached the effect, in fact, and the use of PHANTOMJS cut the figure almost, personal feeling is good, do not know if there will be other problems, yet to be found ...
