ssm+maven实现pdf导出

小灰灰 2022-05-28 00:20 185阅读 0赞

第一步：根据需求新建一个word文档

第二步：下载Adobe Acrobat DC并安装

第三步：用Adobe Acrobat DC新建pdf文件。如图：

![70][]![70 1][]

![70 2][]

第四步：创建form域。a.当word文档以表格形式就不需要再自己额外添加域了；b.当word文档没有表格，需要自己添加域，如下图进行添加域。（这里的域指的是需要被替换的位置）

![70 3][]

![70 4][]

第五步：pom.xml中加入

<dependency>
            <groupId>com.itextpdf</groupId>
                <artifactId>itext-asian</artifactId>
                <version>5.2.0</version>
            </dependency>

会遇到的问题：走到如下图的位置可能会报“pdf not found as file or resource.”找不到文件的错误；

解决方法：https://blog.csdn.net/jla\_jobs/article/details/30074537 这里面讲的很仔细；

我的解决方法：用下面的代码替换如下图标出的那一行运行成功后，再删除下面的代码，还原代码再运行就正常了。

原因我看别人说的是内存溢出（但是表示不懂）

FileInputStream file = new FileInputStream(inputFile);//创建流文件，其中inputFile是你的PDF文档路径
         byte[] b=  new byte[file.available()];//获取字节
        if(file.read(b)>0){
         file.read(b,0,b.length);//将字节读入到文件里
        }
     
      PdfReader reader = null;// iText一个类
    
        //这前直接将文件路径放进来，结果就是读大PDF文件（我的是大于1M）时读不到内存里。
       //reader = new PdfReader(inputFile);
    
        //解决问题的关键
    
        / /更换成这种方式，就可以读到大文件了。我的1M的文件是读到了，再大的没有测试过。
        reader = new PdfReader(new PdfReader(b));
