1.9-SNAPSHOT-Java21
1.9-SNAPSHOT
此版本包含:
1. 压缩/解压 (`compress`)
@@ -29,27 +29,5 @@
- 支持单线程下载和多线程并行下载(基于 HTTP Range 请求)
- 多线程下载自动创建父目录,预分配文件空间
- 使用 Java HttpClient 标准库,支持自动重定向
- 多线程下载块失败时向调用方抛出异常(不再静默吞掉)
- 测试改为本地 HTTP 服务器驱动(不依赖外网),确保可重复执行
1.8 更新内容(历史):
- 版本号升级为 1.8-SNAPSHOT-Java21(pom / version 常量 / README 引用同步)
- 质量插件适配 Java 21:checkstyle 升级至 3.6.0(新增 checkstyle.xml 并绑定 verify 阶段),
SpotBugs 4.8.6.6 替换已停止维护的 FindBugs(新增排除规则),javadoc 升级至 3.12.0(禁用 doclint)
- 修复 SpotBugs 发现的空指针风险:压缩/解压方法 getFileName()/getParent() 空值防御,
加密模块共享 SecureRandom 实例
1.7 更新内容(历史):
- 安全:修复 Zip-Slip 路径穿越漏洞,解压时校验条目路径并拒绝符号/硬链接条目
- 安全:AES 升级为 AES-256/GCM(随机 IV + 认证标签),RSA 实现真实混合加密
(RSA-2048/OAEP 包裹随机 AES-256 会话密钥),密钥文件限制为仅属主可读写
- 健壮性:加解密改为流式处理(支持大文件),临时文件 + 原子替换,中途失败不损坏原数据
- 修复:随机数上界 Integer.MAX_VALUE 溢出;ColorPrintlnPlus 格式码叠加(颜色+加粗等)
- 修复:getHWID 命令执行增加超时并并发排空输出流,Windows 改用 PowerShell CIM(wmic 回退),
修正 Linux 磁盘序列号命令,MAC 优先物理网卡
- 修复:getJarPath 经 URI 解析(正确处理空格与 URL 编码),临时目录改用唯一命名
- 工程:测试全部迁移至 JUnit 5(53 个用例),pom 补充元数据与插件版本,
版本号统一由 pom / MANIFEST Implementation-Version 提供
- 兼容性:向下降级为 Java 21
在 1.8-SNAPSHOT-Java21 的基础上新增文件下载模块并同步 1.9 版本号。
在 1.8-SNAPSHOT 的基础上进行版本升级。
