java - 在 Spring boot 中添加超过 65535 个条目 jar

Question

我创建了句子之间的自定义语义相似度算法。项目创建了 65535 个条目 jar，因为它包含 100,000 个单词。我使用“mvn install:install-file”将自定义 jar 添加到我的 spring boot 项目并创建了 boot jar，但每当我运行项目时，我都会收到此错误。

Answer 1

Spring boot 不支持 jar 中超过 65534 个文件。这是他们的代码。

public int getNumberOfRecords() {
        long numberOfRecords = Bytes.littleEndianValue(this.block, this.offset + 10, 2);
        if (numberOfRecords == 0xFFFF) {
            throw new IllegalStateException("Zip64 archives are not supported");
        }
        return (int) numberOfRecords;
    }

由于它的数据文件，请将其保留在 jar 之外，这也会减少构建时间。
