1.8 更新内容:
|
||||||
- 新增文件下载模块 (`file/download`)
|
- 版本号升级为 1.8-SNAPSHOT-Java21(pom / version 常量 / README 引用同步)
|
||||||
- 支持单线程下载和多线程并行下载(基于 HTTP Range 请求)
|
- 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),
|
||||||
- 多线程下载自动创建父目录,预分配文件空间
|
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)
|
||||||
- 使用 Java HttpClient 标准库,支持自动重定向
|
- 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
|
||||||
|
- 构建验证通过:mvn clean verify(53 个测试用例 + checkstyle + SpotBugs 0 问题)
|
||||||
|
与 mvn javadoc:javadoc 均成功
|
||||||
|
|
||||||
在 1.8-SNAPSHOT 的基础上进行版本升级。
|
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
|
