用POI操作对Word模板内容的替换实例

1.在pom.xml中导入相关依赖包

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>4.0.1</version>
</dependency>

3.工具如下：

package net.longjin.comm.utils;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import javax.servlet.http.HttpServletResponse;

import net.longjin.CaseModuleLocalJdbcApplication;
import net.longjin.comm.init.InitUserRoleResources;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.model.FieldsDocumentPart;
import org.apache.poi.hwpf.usermodel.Field;
import org.apache.poi.hwpf.usermodel.Fields;
import org.apache.poi.hwpf.usermodel.Range;
import org.springframework.boot.SpringApplication;

        }

    }

    public static void main(String[] args) {

}
4.操作结果如下：
