到目前为止，我的代码工作良好，我正在临时目录中创建文件并处理它。

但是现在我正在尝试提供我实际想要创建xml文件的特定目录。 因此，在方法CreateTMPXMLFile中，我将逻辑从return files.createTempFile（prefix，XML_SUFFIX，“/tmp/in”）；更改为逻辑return file.CreateTempFile（prefix，XML_SUFFIX，“/tmp/in”）；，然后我得到错误，因为Java:不兼容类型:Java.lang.String不能转换为Java.io.file。

如果我试图更改这里的逻辑，那么它会影响我使用CreateTMPXMLFile方法的另一个方法。

我真不明白如何解决这个问题。 下面是我的代码:

 @Slf4j

    public static final String XML_SUFFIX = ".xml";

    private void processleifZipFile() {
        final AtomicBoolean isInsideLeiRecord = new AtomicBoolean();
        isInsideLeiRecord.set(false);
        final StringBuilder currentLeiRecordXml = new StringBuilder();

        try (FileSystem zipFs = FileSystems.newFileSystem(jobRunner.getInputZipPath(), null)) {
            Path tmpXMLPath = xmlFileFromLeiZipFile(zipFs);

            try (Stream<String> lines = Files.lines(tmpXMLPath)) {
                AtomicInteger processedLinesCounter = new AtomicInteger();
                AtomicInteger currentLineNumber = new AtomicInteger();
                lines.sequential().forEach(handleLineAndIncrementLineNumber(isInsideLeiRecord, currentLeiRecordXml, processedLinesCounter, currentLineNumber));
                log.info("{} lines of XML file inside LEIF input ZIP file {} processed.", processedLinesCounter.get(), jobRunner.getInputZipPath());

                log.info("Path to LEIF XML file inside ZIP file: {}.", xmlFileInsideZip);
                return copyReplacing(xmlFileInsideZip, tmpXmlPath);
            }
        }
        throw new IllegalStateException("No file found in LEI ZIP file " + jobRunner.getInputZipPath() + ".");
    }
