2、重写Breaker.java文件，用于中文换行
新建org.xhtmlrenderer.layout文件夹，新建一个java文件，将以下内容粘贴进去
package org.xhtmlrenderer.layout;

3、html转换pdf代码

public static void html2pdf(String content, String pdfFile) throws Exception {
OutputStream os = new FileOutputStream(pdfFile);
ITextRenderer renderer = new ITextRenderer();
StringBuffer html = new StringBuffer();
content = content.replace("宋体", "SimSun");
content = content.replace("黑体", "SimHei");
content = content.replace("微软雅黑", "Microsoft YaHei");
content = content.replace("微软正黑体", "Microsoft JhengHei");
content = content.replace("新宋体", "NSimSun");

content = content.replace("font-family:"", "font-family:SimSun;");
content = content.replace("font-family:""", "font-family:SimSun;");
// DOCTYPE 必需写否则类似于 这样的字符解析会出现错误
html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">");

try {
FileTypeConvertUtil.html2pdf(content, pdfFile);

e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
备注：html里面需要添加上一下代码
html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">");
html.append("<html xmlns=\"http://www.w3.org/1999/xhtml\">").append("<head>")
.append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />")
table的样式需要添加table-layout: fixed;word-break:break-strict;是为了中文代码换行。
1、core-renderer.jar该jar包修改过中文不换行问题
public static String getConversionHtmlCode(String linkcss,String htmlCode,String title){
String css = "";
css +="<style>";
css +="table{";
css +=" border-collapse: collapse;";
css +=" font-size: 15px;";
css +=" width: 98%;";
css +="}";
css +="";
css +="td{";
css +=" border: 1px solid #ddd;";
css +=" text-align: left;";
css +=" white-space: nowrap";
css +="}";
css +="th{";
css +=" border: 1px solid #ddd;";
css +=" text-align: left;";
css +="}";
css +="</style>";
String html = "<html><head>"+css+"</head><body margin:0;margin-top: 15px;margin-bottom: 15px; text-align: center; font-family:SimSun;\" >"+ title+""+ htmlCode + "</body></html>";
System.out.println("html:"+html);
return html;
本项目中就使用了iText库进行写的PDF文件到服务器，所以就没有写Flying Saucer库下的实例方法了。的HTIM字符串、也是直接上代码，简单易懂、相信大家都能看的懂得、对应的包一定要导入正确，否则会报错呦！不过需要注意的是，你在应用第三方库是，导包一定要导入正确，否则会有一些方法是无法使用的。Flying Saucer库下的可以看：2.1和2.2代码实例。iText库下的可以看：1.1和1.2代码实例。iText库下的可以看：1.3代码实例。的HTML的字符串时、我们直接上代码，简单易懂、
修改导出的ftl模板
在table中加入样式, 设置固定宽度,设置换行
CSS：width="800px" style="table-layout:fixed; word-wrap:break-word; word-break:break-all"
th加入样式style="text-align: center;width:10%;"
解决itext生成pdf文件时中文换行的问题，由于使用低版本的flying saucer，不支持中文换行，本文给出了在不更改jar包的前提下的，可实施的解决方案。问题描述之前的文章提到了笔者使用itext+f lying saucer+freemarker生成pdf的实现方案，项目中所有的报表功能早期都使用了这种方案，由于flying saucer的版本的jar包不支持中文字符的自动换行，之前的功...
在利用itext将html文件转化为pdf文件的过程中，需要适当的调整字体，下面介绍字体的使用样式：字体支持的样式 itext核心库中主要支持一下几个各种的字体文件：.AFM/.PFB/.TTF/.otf/.ttc/.wof 2. 利用DefaultFontProvider 只是支持 14 Standard Type 1 fonts and 12 fonts 主要字体...
首先，当然是找到能够解析PDF的完美组件，百度和谷歌不约而同的告诉我们。IText是王道。而目前开源的组件中，Itext的确是一个First Choice，如果各位单纯是做把图片转成PDF或者自己写了Velocity或者FreeMarker模板生成了HTML是非常推荐直接用Itext来进行的。
下面就是用Flying Saucer（xhtmlrendere）来实现的代码：

一：遇到的问题;
1、 中文不支持
2、 中文不换行
3、 如何显示
4、 不显示签章
二：生成（根据html字符串来生成pdf，方便我们的替换）
下边是应用itext进行编写的生成pdf代码（这里要支持中文需要导入相应的iTextAsia
