推荐答案

FlyingSaucer / XHTMLRenderer（ https://github.com/flyingsaucerproject/flyingsaucer ）做一个很好的HTML> PDF转换，但它不工作的魔法：涉及到几个步骤。

FlyingSaucer/XHTMLRenderer (https://github.com/flyingsaucerproject/flyingsaucer) does a good job of HTML > PDF conversion however it does not work by magic: there are a few steps involved.

假设您想通过一些链接或按钮导出现有的JSP：

Assuming you wanted to export an existing JSP via some Link or Button:

• 一些控制器或Servlet通过重新生成JSP所需的所有
  params（即原来是
  呈现）。

• PDF export Button calls a some Controller or Servlet passing all params necessary to regenerate the JSP (i.e. as it was originally rendered).

或Servlet必须调用JSP（确保设置任何所需的

模型属性），并将响应写入字符串（而不是写入标准响应的
）。

This Action or Servlet has to invoke the JSP (ensuring any required
model attributes are set) and write the Response to a String (rather than writing to the standard response).

将此String传递给XHTMLRenderer以生成PDF。

Pass this String to XHTMLRenderer to generate the PDF.

将HTMLRenderer返回的btye [

Stream the btye [] returned by HTMLRenderer to the client.

我在这里使用一个简单的Servlet添加了一个完整的端到端示例。但是，任何框架的原则都是一样的，所以你应该能够根据需要进行调整。

I have added a complete end-to-end example here using a simple Servlet. However the principles will be the same with any framework so you should be able to adapt as required.
