JAVA实现Word(doc)文件读写
1、pom.xml依赖
<dependencies>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
</dependencies>
2、读取文件类ReadDoc.java
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.*;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
public class ReadDoc {
public void testReadByDoc(String path) throws Exception {
InputStream is = new FileInputStream(path);
HWPFDocument doc = new HWPFDocument(is);
//输出书签信息
this.printInfo(doc.getBookmarks());
//输出文本
System.out.println(doc.getDocumentText());
Range range = doc.getRange();
this.printInfo(range);
//读表格
this.readTable(range);
//读列表
this.readList(range);
//把当前HWPFDocument写到输出流中
doc.write(new FileOutputStream("D:\\test.doc"));
is.close();
}
/**
* 输出书签信息
* @param bookmarks
*/
private void printInfo(Bookmarks bookmarks) {
int count = bookmarks.getBookmarksCount();
System.out.println("书签数量:" + count);
Bookmark bookmark;
for (int i=0; i<count; i++) {
bookmark = bookmarks.getBookmark(i);
System.out.println("书签" + (i+1) + "的名称是:" + bookmark.getName());
System.out.println("开始位置:" + bookmark.getStart());
System.out.println("结束位置:" + bookmark.getEnd());
}
}
/**
* 读表格
* 每一个回车符代表一个段落,所以对于表格而言,每一个单元格至少包含一个段落,每行结束都是一个段落。
* @param range
*/
private void readTable(Range range) {
//遍历range范围内的table。
TableIterator tableIter = new TableIterator(range);
Table table;
TableRow row;
TableCell cell;
while (tableIter.hasNext()) {
table = tableIter.next();
int rowNum = table.numRows();
for (int j=0; j<rowNum; j++) {
row = table.getRow(j);
int cellNum = row.numCells();
for (int k=0; k<cellNum; k++) {
cell = row.getCell(k);
//输出单元格的文本
System.out.println(cell.text().trim());
}
}
}
}
/**
* 读列表
* @param range
*/
private void readList(Range range) {
int num = range.numParagraphs();
Paragraph para;
for (int i=0; i<num; i++) {
para = range.getParagraph(i);
if (para.isInList()) {
System.out.println("list: " + para.text());
}
}
}
/**
* 输出Range
* @param range
*/
private void printInfo(Range range) {
//获取段落数
int paraNum = range.numParagraphs();
System.out.println(paraNum);
for (int i=0; i<paraNum; i++) {
System.out.println("段落" + (i+1) + ":" + range.getParagraph(i).text());
}
int secNum = range.numSections();
System.out.println(secNum);
Section section;
for (int i=0; i<secNum; i++) {
section = range.getSection(i);
System.out.println(section.getMarginLeft());
System.out.println(section.getMarginRight());
System.out.println(section.getMarginTop());
System.out.println(section.getMarginBottom());
System.out.println(section.getPageHeight());
System.out.println(section.text());
}
}
}
3、功能测试
public class ReadDocTest {
public static void main(String[] args) throws Exception {
ReadDoc rd = new ReadDoc();
rd.testReadByDoc("D:\\MaintainCase.doc");
}
}
4、写入文件类WriteDoc.java
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Range;
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.List;
public class WriteDoc {
public void testWrite() throws Exception {
List<Users> list = new ArrayList<Users>();
list.add(new Users("a","男",10,new SimpleDateFormat("yyyy-MM-dd").parse("2018-08-08")));
list.add(new Users("b","女",20,new SimpleDateFormat("yyyy-MM-dd").parse("2017-07-07")));
String templatePath = "D:\\template.doc";
InputStream is = new FileInputStream(templatePath);
OutputStream os = null;
HWPFDocument doc = new HWPFDocument(is);
Range range = doc.getRange();
for(int i=0;i<list.size();i++){
Users user = list.get(i);
//把range范围内的${reportDate}替换为当前的日期
range.replaceText("${name}", user.getName());
range.replaceText("${sex}", user.getSex());
range.replaceText("${age}", String.valueOf(user.getAge()));
range.replaceText("${date}", user.getBirthday().toString());
os = new FileOutputStream(new File("D:\\"+user.getName()+".doc"));
//把doc输出到输出流中
doc.write(os);
}
os.close();
is.close();
}
}
5、功能测试
Users类
import java.util.Date;
public class Users {
String name;
String sex;
int age;
Date birthday;
public Users() {}
public Users(String name, String sex ,int age, Date birthday) {
this.name = name;
this.sex = sex;
this.age = age;
this.birthday = birthday;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
6、测试类
public class WriteDocTest {
public static void main(String[] args) throws Exception {
WriteDoc wd = new WriteDoc();
wd.testWrite();
}
}
