从ResourceStream提取压缩文件会引发错误“无效的存储块长度". [英] Extracting zipped file from ResourceStream throws error "Invalid stored block lengths"

问题描述

我正在尝试使用以下方法从当前的JAR中提取ZIP文件:

I am trying to extract a ZIP file from my current JAR using:

InputStream resource = getClass().getClassLoader().getResourceAsStream(name);

这将获得正确的InputStream，但是当我尝试使用以下代码将其解压缩时，它给出了一个错误(我将每个文件存储到Hashmap<file, filename>中):

This get the correct InputStream, but it gives an error when I try to unzip it using the following code (I'm storing each file into a Hashmap<file, filename>):

public static HashMap<String, String> readZip(InputStream inputStream) throws IOException {
    byte[] buffer = new byte[1024];
    HashMap<String, String> list = new HashMap<>();
    ZipInputStream zipInputStream = new ZipInputStream(inputStream);
    ZipEntry entry = zipInputStream.getNextEntry();
    while (entry != null) {
        if (!entry.isDirectory()) {
            StringBuilder stringBuilder = new StringBuilder();
            while (IOUtils.read(zipInputStream, buffer) > 0) {
                stringBuilder.append(new String(buffer, "UTF-8"));
            }
            list.put(stringBuilder.toString(), entry.getName());
        }
        zipInputStream.closeEntry();
        entry = zipInputStream.getNextEntry();
    }
    zipInputStream.closeEntry();
    zipInputStream.close();
    return list;
}

但是，当我尝试执行此操作时，会出现此异常(在IOUtils.read上)

However when I try to do this, I get this exception (on IOUtils.read)

java.util.zip.ZipException: invalid stored block lengths
   at java.util.zip.InflaterInputStream.read(Unknown Source)
   at java.util.zip.ZipInputStream.read(Unknown Source)

我做错了吗?我已经对错误进行了大量的搜索，但没有发现与我的问题有关的任何信息.

Am I doing this wrong? I've done plenty of googling of the error, and I didn't see anything related to my issue.

推荐答案

感谢@PaulBGD的上述回答.它节省了我几个小时来弄清楚我的系统发生了什么，我在我的pom.xml文件中添加了以下新代码片段(在阅读Paul的答案之前，我没有意识到这是根本原因):

Thanks to @PaulBGD's answer above. It saved me hours to figure out what happened to my system I add the following new snippets into my pom.xml file (which I didn't realize is the root cause before reading Paul's answer):

<resources>
  <resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
    <includes>
      <include>**/*.version</include>
      <include>**/*.properties</include>
      <include>**/*.xml</include>
      <include>**/*.csv</include>
      <include>**/*.txt</include>
      <include>**/*.gif</include>
      <include>**/*.json</include>
      <include>**/*.xlsx</include>
      <include>rythm/**</include>
    </includes>
  </resource>
</resources>

但是我没有直接接受Paul的回答，相反，我认为这些xlsx文件不应该通过资源插件的过滤管道，因此我在pom中添加了另一个resource:

However I didn't take Paul's answer directly, instead I don't think those xlsx files should go through the resource plugin's filtering pipeline, thus I added another resource into pom:

  <resource>
    <directory>src/main/resources</directory>
    <filtering>false</filtering>
    <includes>
      <include>**/*.xlsx</include>
    </includes>
  </resource>

它解决了我的问题，而没有将源编码设置从UTF-8更改为ISO-8859-1

And it fixed my problem without changing the source encoding setting from UTF-8 to ISO-8859-1
