根据xsl模板及xml数据文件生成pdf（文字内容复制不乱码）

使用FOP技术，配合xsl模板及XML数据生成PDF报表和线上打印业务。
主要依赖包：fop.jar

第一部分对数据处理

package com.cisetech.put.utils.fop;

import java.io.Serializable;

/**

 */
public class ReportData implements Serializable {
    private static final long serialVersionUID = -2722248902864797698L;

    private byte[] mbData = null;
    private String msContentType = null;

    public byte[] getData() {
        return mbData;
    }
    public void setData(byte[] pData) {
        mbData = pData;
    }
    public String getContentType() {
        return msContentType;
    }
    public void setContentType(String pContentType) {
        msContentType = pContentType;
    }
}

应用xsl模板进行PDF版面排版，使用XML方式组装需打印数据。

            TransformerFactory factory = TransformerFactory.newInstance();
            Transformer transformer = factory.newTransformer(new StreamSource(new File(xsltFile)));
