本文将介绍如何使用Spire.Doc for Java创建Word邮件合并模板文档，以及合并文本值到模板。

import com.spire.doc.*;
import com.spire.doc.documents.Paragraph;
import java.text.SimpleDateFormat;
import java.util.Date;


public class MailMerge {
    public static void main(String[] args) throws Exception {

        String output = "output/mailMerge.docx";

        //创建Document实例
        Document document = new Document();

        //添加节
        Section section = document.addSection();

        //添加三个段落
        Paragraph para = section.addParagraph();
        Paragraph para2 = section.addParagraph();
        Paragraph para3 = section.addParagraph();

        //添加三个合并域
        para.setText("联系人 : ");
        para.appendField("Contact Name", FieldType.Field_Merge_Field);
        para2.setText("电话 : ");
        para2.appendField("Phone", FieldType.Field_Merge_Field);
        para3.setText("日期 : ");
        para3.appendField("Date", FieldType.Field_Merge_Field);

        //按合并域名称，设置合并域的文本值
        Date currentTime = new Date();
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String dateString = formatter.format(currentTime);
        String[] filedNames = new String[]{"Contact Name", "Phone", "Date"};
        String[] filedValues = new String[]{"李 生", "+ (86) 18812345678", dateString};

        //合并文本到模板
        document.getMailMerge().execute(filedNames, filedValues);

        //保存文档
        document.saveToFile(output, FileFormat.Docx);
    }
}
