JAXB 解组 2.7gb xml 文件答案

【问题标题】：JAXB unmarshalling a 2.7gb xml fileJAXB 解组 2.7gb xml 文件
【发布时间】：2020-07-04 20:15:54
【问题描述】：

我有一个已解压缩的 Adobe Premiere Pro 项目文件，因此它现在是一个详细说明我的电影编辑项目的 xml 文件。

文件现在是 2.7gb...

为此，我使用 Intellij 的函数从 xml 文件创建了一个 XSD 模式，然后再次使用 Intellij 的 JAXB 工具，从 .xsd 生成了一个包含表示 xml 层次结构的类的包。

我的解组代码如下：


import mypackage.PremiereDataType;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBElement;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import java.io.File;

public class Main {

    public static void main(String[] args) throws JAXBException {
    // write your code here

        JAXBContext jaxbContext;
        jaxbContext = JAXBContext.newInstance("mypackage");
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        JAXBElement<PremiereDataType> premiereDataJAXB
                = (JAXBElement<PremiereDataType>) unmarshaller.unmarshal(
                new File("20200108_WLM_MW_v706_JGal_review_R2_markers_CONSOLIDATE.xml"));
        System.out.println(premiereDataJAXB);

    }
}

我的机器有 32GB 的内存。我不了解如何在 Intellij 中微调内存使用情况，但我怀疑内存不足？

大约十五分钟后，程序崩溃并出现 EXCEPTION_ACCESS_VIOLATION。

# A fatal error has been detected by the Java Runtime Environment:

Process finished with exit code 1

崩溃的日志文件如下（被截断，所以这个问题不违反字符限制）。指示“对象空间”的行是否已达到“已使用 99%”是否表明存在问题？我可以在某处增加限制以增加对象空间吗？

任何帮助解决这个问题将不胜感激！谢谢！

【问题讨论】：

标签： java memory jaxb

【解决方案1】：

这是一个大文件。将 VM 启动设置 -Xms 和 -Xmx 设置得尽可能大。

这是一个崩溃而不是 OutOfMemoryException，因此可能值得尝试 JDK9+。然后字符串表也更小（如果你有拉丁字符），这也可能给解组 XML 提供更好的机会。如果您遇到困难，使用 XML SAX 处理程序可能允许您在子部分中提取它，但需要更多的编码工作。

【解决方案2】：

我切换到 Java 13 并跳过障碍让 JAXB 与该版本一起工作。不再有 EXCEPTION_ACCESS_VIOLATION！
