java - FOP – 多页序列的 OutofMemoryError
问题描述
我使用 Apache FOP 2.2 生成 PDF 报告。每当有超过 20K 的记录时，我都会收到“OutofMemoryError: Java heap space”错误。我尝试增加页面序列的数量以提高性能，但在将 XML 转换为 PDF 以获取超过 20K 的记录时仍然会出现内存不足错误。在没有多页序列的情况下，只有 2K 条记录被成功转换。下面是使用的 XML 结构和 XSL 模板。
要求是生成至少有 75K 记录的 PDF（取决于 DB 数据）。请建议如何修改 XSL-FO 模板或 XML 格式以解决此问题。
