使用Java Files.copy复制后，出现空白页面的PDF文件 [英] PDF file with empty pages appearing after Copying using Java Files.copy

问题描述

我正在尝试将我的班级路径中的文件复制到另一个临时位置.

I am trying to copy a file in my Class path to another temp location.

这是它的代码:

    InputStream inputStream = this.getClass().getClassLoader()
            .getResourceAsStream(readmeFile);

    Path path = Paths.get(tempFilesOutputPath + File.separator + readmeFile);
    try {
        Files.copy(inputStream, path, StandardCopyOption.REPLACE_EXISTING);
        inputStream.close();

    } catch (IOException e) {
        throw e;
    }

readMeFile有2页，在tempFilesOutputPath文件夹中复制的文件也有2页，但没有任何内容.

readMeFile has 2 pages, the copied file in the tempFilesOutputPath folder also has two pages but without any content.

请让我知道我是在犯错误还是必须以其他方式来完成.

Please let me know if I am making some mistake or it has to be done in a different way.

干杯， Madhu

问题完全无关.我正在使用Maven复制资源将资源复制到src/main/resources/

Issue was totally unrelated. I was using maven copy resource to copy the resources under my src/main/resources/

这是我的Maven资源:

this was my maven resource:

        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>**/*.txt</include>
                <include>**/*.html</include>
                <include>**/*.pdf</include>
            </includes>
        </resource>

由于过滤是在PDF文件上进行的，因此作为空doco复制到了目标文件夹.

Since the filtering was on PDF file was copied as an empty doco to the target folder.

我只是将其分为两个资源，并过滤掉了PDF文件.

I just seperated it into two resources with filtering off for PDF file.

        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>**/*.txt</include>
                <include>**/*.html</include>
            </includes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>false</filtering>
            <includes>
                <include>**/*.pdf</include>
            </includes>
        </resource>

多亏了Drew Buckley，我在尝试对该文件进行二进制比较时遇到了问题.项目上的实际文件是不同的，而从maven复制的目标文件夹上的文件是不同的.

Thanks to Drew Buckley, I got the issue when trying to do a binary comparison of the file. Actual file on the project was different and the one on the target folder which gets copied from the maven was different.

现在工作正常.
