IText利用freemarker生成pdf

公司需要动态生成PDF，搞了很久，终于搞好，现在拿出主要代码分享一下
唯一的不足是不支持中文换行，如果有人知道可以交流下

//step1 加载template模板文件
Configuration cfg = new Configuration();
cfg.setDirectoryForTemplateLoading(new File(templateBasePath));
cfg.setObjectWrapper(new DefaultObjectWrapper());
//编码防止乱码
cfg.setDefaultEncoding("UTF-8");
Template t = cfg.getTemplate("cover.ftl");
//编码防止乱码
t.setEncoding("UTF-8");
String html = "demo.html";
File file = new File(html);
if (!file.exists()) {
     file.createNewFile();
}
Map map = new HashMap();
Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file), "UTF-8"));
t.process(map, out);
String url = new File(html).toURI().toURL().toString();
String outputFile = "cover.pdf";
// step 2
OutputStream os = new FileOutputStream(outputFile);
org.xhtmlrenderer.pdf.ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(url);
renderer.getSharedContext().setBaseURL("file:///" + imageBasePath);
// step 3 解决中文支持
org.xhtmlrenderer.pdf.ITextFontResolver fontResolver = renderer.getFontResolver();
fontResolver.addFont("C:/Windows/Fonts/simsun.ttc", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
renderer.layout();
renderer.createPDF(os);
os.close();
//maven 所需要的jar
