java-如何使用apache POI在docx中插入当前日期字段
作者:互联网
我不知道如何将日期和时间字段插入docx.
我想我必须使用类似
run.getCTR().addNewFldChar().setFldCharType(STFldCharType.???)
但我不知道如何
波纹管是一种SSCCE,其中insertCurrentXxxxField()函数的行为不符合需要.
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
public class InsertCurrentDateAndTimeInDocxUsingApachePOI {
public static void main(String[] args) throws IOException {
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run = paragraph.createRun();
run.setText("Current date:");
insertCurrentDateField(run);
run.setText(" current time:");
insertCurrentTimeField(run);
FileOutputStream out = new FileOutputStream(new File("CurrentDateAndTime.docx"));
document.write(out);
}
private static void insertCurrentDateField(XWPFRun run){
run.setText("${here should be the current date field DD.MM.YY}");
}
private static void insertCurrentTimeField(XWPFRun run){
run.setText("${here should be the current time field HH:MM:SS}");
}
}
解决方法:
在Word中,字段在段落中,而不在运行中.但是必须在字段之前关闭运行,并在字段之后打开新的运行.
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
public class InsertCurrentDateAndTimeInDocxUsingApachePOI {
public static void main(String[] args) throws IOException {
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run = paragraph.createRun();
run.setText("Current date:");
insertCurrentDateField(paragraph);
run = paragraph.createRun();
run.setText(" current time:");
insertCurrentTimeField(paragraph);
FileOutputStream out = new FileOutputStream(new File("CurrentDateAndTime.docx"));
document.write(out);
}
private static void insertCurrentDateField(XWPFParagraph paragraph){
XWPFRun run = paragraph.createRun();
paragraph.getCTP().addNewFldSimple().setInstr("DATE \\@ \"yyyy-MM-dd\" \\* MERGEFORMAT");
}
private static void insertCurrentTimeField(XWPFParagraph paragraph){
XWPFRun run = paragraph.createRun();
paragraph.getCTP().addNewFldSimple().setInstr("TIME \\@ \"HH:mm:ss\" \\* MERGEFORMAT");
}
}
