OpenOffice安装略

1.引入依赖

        </dependency>

        <!--springboot支持包，里面包括了自动配置类 -->

2.编写配置文件

server.port=8765
jodconverter.local.enabled=true
#home:安装地址
#jodconverter.local.office-home=C:/Program Files (x86)/OpenOffice 4
jodconverter.local.max-tasks-per-process=10
jodconverter.local.port-numbers=8100
#热部署生效
spring.devtools.restart.enabled=true

3.在控制器中使用

package com.example.openofficedemo.controller;

import org.apache.commons.io.IOUtils;
import org.jodconverter.DocumentConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;

@Controller
public class MyController {
    // 第一步：转换器直接注入
    @Autowired
    private DocumentConverter converter;

    @Autowired
    private HttpServletResponse response;

    @RequestMapping("toPdfFile")
    public String toPdfFile() {
        File file = new File("D:\\test.doc");//需要转换的文件
        try {
            File newFile = new File("D:/obj-pdf");//转换之后文件生成的地址
            if (!newFile.exists()) {
                newFile.mkdirs();
            }
            //文件转化
            converter.convert(file).to(new File("D:/obj-pdf/hello.pdf")).execute();
            //使用response,将pdf文件以流的方式发送的前段
            ServletOutputStream outputStream = response.getOutputStream();
            InputStream in = new FileInputStream(new File("D:/obj-pdf/hello.pdf"));// 读取文件
            // copy文件
            int i = IOUtils.copy(in, outputStream);
            System.out.println(i);
            in.close();
            outputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "This is to pdf";
    }
}
