java动态导出PDF（利用itext）
项目基于ssm框架，使用itext动态导出pdf文件：
1.引入两个jar包：itextpdf-5.5.5.jar、itext-asian-5.2.0.jar
说明：
1.itextpdf-5.5.5.jar 操作导出pdf
2.itext-asian-5.2.0.jar 导出pdf中的中文处理
3.动态导出pdf文件，在java代码中设置pdf的内容、样式。
2.页面点击导出pdf并弹出保存提示框。代码如下：
jsp代码：
<!DOCTYPE html> <%@ page language="java" contentType="text/html; charset=UTF-8"%> <% String ctxPath = request.getContextPath(); request.setAttribute("ctxpath", ctxPath);//项目根路径 %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>首页</title> <script type="text/javascript"> </script> </head> <body> <form action="${ctxpath}/test/testpdf.html" method="post"> <input id="test" name="test" type="submit" value="导出pdf"/> </form> </body> </html>
页面效果：
controller代码：
