方案：我有调用Soap Web服务的代码，得到的附件是zip文件。然后将其解压缩，浏览所有文件，获取我想要的一个文件，即csv文件，并获取csv文件的内容：
public static void unzipTry2(AttachmentPart att) throws IOException, SOAPException {
try (ZipInputStream zis = new ZipInputStream(att.getRawContent())) {
byte[] buffer = new byte[1024];
for (ZipEntry zipEntry = zis.getNextEntry(); zipEntry != null; zipEntry = zis.getNextEntry()) {
if (zipEntry.isDirectory()) {
continue;
}
if (!zipEntry.getName().equals("FileIwant.csv")) {
continue; //if it's not the file I want, skip this file
}
System.out.println(zipEntry.getName());
for (int len = zis.read(buffer); len > 0; len = zis.read(buffer)) {
//System.out.write(buffer, 0, len);
String testString = new String(buffer,0,len);
processCSVString(testString);
}
}
}
}
效果很好。但是，我得到的CSV文件仅包含一行，现在应该可以，但是将来可能包含多行。由于它是CSV文件，因此我需要逐行解析。此代码还必须适用于CSV文件包含多行的情况，这就是我不确定它是否有效的地方，因为没有办法测试（我不控制此方法的输入，来自网络服务）。
您能告诉我内部for循环是否逐行读取LINE文件吗？ ：
for (int len = zis.read(buffer); len > 0; len = zis.read(buffer)) {
//System.out.write(buffer, 0, len);
String testString = new String(buffer,0,len);
processCSVString(testString);
}
答案 0 :(得分：0)
BufferedReader是Java的“事物”，可以逐行读取Reader。而您需要的粘合剂是InputStreamReader。然后，您可以将/*
