+
+## 逐项修复详情
+
+### ✅ #1 RSA.java:262 — switch 表达式 → if-else-if（jre8 兼容）
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/encrypt/RSA.java` |
+| **方法** | `ecKeySizeToCurveName(int keySize)` |
+| **问题** | 使用了 Java 12+ 的 switch 箭头语法 (`case 256 -> ...`)，jre8/jre11 分支无法编译 |
+| **修复** | 改为 `if (keySize == 256) { ... } else if (...)` 链式写法 |
+| **影响分支** | jre8, jre11 恢复兼容 |
+
+```diff
+- return switch (keySize) {
+-     case 256 -> "secp256r1";
+-     case 384 -> "secp384r1";
+-     case 521 -> "secp521r1";
+-     default -> throw new IllegalArgumentException(...);
+- };
++ if (keySize == 256) {
++     return "secp256r1";
++ } else if (keySize == 384) {
++     return "secp384r1";
++ } else if (keySize == 521) {
++     return "secp521r1";
++ } else {
++     throw new IllegalArgumentException(...);
++ }
+```
+
+---
+
+### ✅ #2 JwtUtil.java:52 — `instace()` → `instance()`（API 拼写错误）
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/util/JwtUtil.java` |
+| **方法** | 公开静态方法 + 内部类名 |
+| **问题** | 单例获取方法名拼写错误 `instace()`，影响所有外部调用者 |
+| **修复** | 方法名 `instace()` → `instance()`；内部类 `Instace` → `Instance`；同步更新全部 3 处引用 |
+| **影响范围** | 全分支（公开 API 变更，⚠️ 调用方需同步修改） |
+
+**变更点清单：**
+1. L52: `public static JwtUtil instace()` → `instance()`
+2. L67: `Instace.jwtUtil` → `Instance.jwtUtil`
+3. L94: `Instace.jwtUtil` → `Instance.jwtUtil`
+4. L95: `return instace()` → `return instance()`
+5. L98: `private static class Instace` → `class Instance`
+
+> ⚠️ **破坏性变更**: 外部代码中所有 `JwtUtil.instace()` 调用需改为 `JwtUtil.instance()`
+
+---
+
+### ✅ #3 JwtUtil.java:173 — `var` → 显式类型（jre8 兼容）
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/util/JwtUtil.java` |
+| **位置** | `compact()` 方法内 L173 |
+| **问题** | 使用 Java 10+ 的 `var` 局部变量类型推断关键字 |
+| **修复** | 改为显式类型声明 `io.jsonwebtoken.JwtBuilder builder` |
+| **影响分支** | jre8, jre10, jre11 恢复兼容 |
+
+```diff
+- var builder = Jwts.builder()
++ io.jsonwebtoken.JwtBuilder builder = Jwts.builder()
+```
+
+---
+
+### ✅ #4 RequestHeader.java:121 — `geRespTime()` → `getRespTime()`
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/http/RequestHeader.java` |
+| **方法** | L121 |
+| **问题** | getter 方法名缺少字母 `t`，与 `RESPONSE_TIME` 常量命名不一致 |
+| **修复** | `geRespTime()` → `getRespTime()` |
+| **联动修复** | `RSA.java:681` 调用处 `.geRespTime()` → `.getRespTime()` 同步修正 |
+
+> ⚠️ **破坏性变更**: 外部代码中所有 `.geRespTime()` 调用需改为 `.getRespTime()`
+
+---
+
+### ✅ #5 ImgUtil.java:266 — `connectBytes()` 数组拷贝 Bug
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/util/ImgUtil.java` |
+| **方法** | `connectBytes(byte[] front, byte[] after)` L264-269 |
+| **问题** | 第一个 `System.arraycopy` 的 length 参数错误使用了 `after.length` 而非 `front.length`。当 front.length > after.length 时会截断数据；当 front.length < after.length 时会越界读取 |
+| **修复** | `System.arraycopy(front, 0, result, 0, after.length)` → `... result, 0, front.length)` |
+
+```diff
+  public static byte[] connectBytes(byte[] front, byte[] after) {
+      byte[] result = new byte[front.length + after.length];
+-     System.arraycopy(front, 0, result, 0, after.length);
++     System.arraycopy(front, 0, result, 0, front.length);
+      System.arraycopy(after, 0, result, front.length, after.length);
+      return result;
+  }
+```
+
+---
+
+### ✅ #6 ObjUtil.java:393 — `System.out.println` → 日志框架
+
+| 项目 | 内容 |
+|------|------|
+| **文件** | `src/main/java/com/yexuejc/base/util/ObjUtil.java` |
+| **位置** | `getUnderlineMap()` 方法 catch 块 L393 |
+| **问题** | 使用 `System.out.println(e.getMessage())` 输出异常信息，生产环境可能丢失关键错误日志 |
+| **修复** | 替换为已有的 `java.util.logging.Logger` 实例，使用 `Level.WARNING` 级别记录完整异常堆栈 |
+
+```diff
+- System.out.println(e.getMessage());
++ log.log(Level.WARNING, "获取对象字段映射失败: ", e);
+```
+
+---
+
+### ⏭ #7 FileUtil.java:295 — connectBytes（无需处理）
+
+| 项目 | 内容 |
+|------|------|
+| **状态** | **无需处理** |
+| **原因** | 当前代码中 `FileUtil.java` 不存在 `connectBytes()` 方法。审计报告中该条目基于历史版本代码，该方法可能在之前重构中已被移除或从未存在于此文件中。实际仅 `ImgUtil.java` 存在此方法并已修复（见 #5）。 |
+
+---
+
+## 破坏性变更汇总（⚠️ 调用方需关注）
+
+| # | 原 API | 新 API | 影响文件 |
+|---|--------|--------|----------|
+| 1 | `JwtUtil.instace()` | `JwtUtil.instance()` | 所有调用方 |
+| 2 | `header.geRespTime()` | `header.getRespTime()` | 所有调用方 |
+
+---
+
+## 修复后兼容性矩阵
+
+| JDK 版本 | switch 表达式 | var 关键字 | 状态 |
+|----------|---------------|------------|------|
+| jre8 | ✅ 已改 if-else | ✅ 已改显式类型 | **可编译** |
+| jre11 | ✅ 已改 if-else | ✅ 已改显式类型 | **可编译** |
+| jre17 | ✅ 兼容 | ✅ 兼容 | **可编译** |
+| jre21 (主) | ✅ 兼容 | ✅ 兼容 | **可编译** |
