692-696: 潜在缺陷：reply 未发送
handle(CalculateImageHashOnBackupStorageMsg)方法创建了reply并设置了错误，但未通过bus.reply(msg, reply)发送。这会导致调用方永远收不到响应，可能造成超时。🔎 建议修复
@Override protected void handle(CalculateImageHashOnBackupStorageMsg msg) { CalculateImageHashOnBackupStorageReply reply = new CalculateImageHashOnBackupStorageReply(); reply.setError(operr("sftp backup storage do not support calculate image hash")); + bus.reply(msg, reply); }

3-3: 多余的空行此处新增的空行看起来是无意义的格式变更。如果这不是代码格式化工具的要求，建议移除以保持代码整洁。
simulator/simulatorImpl/src/main/java/org/zstack/simulator/storage/backup/SimulatorBackupStorage.java (1)
141-150: 实现可行，但与部分现有处理器风格不一致新增的处理方法使用
bus.replyErrorByMessageType()返回错误，这是更安全的方式。但请注意，该类中部分现有处理器（如handle(SyncImageSizeOnBackupStorageMsg)在 Lines 100-102）使用的是throw new CloudRuntimeException("not supported yet")。建议保持一致性，或者在后续统一将抛异常的方式改为消息回复方式。
plugin/ceph/src/main/java/org/zstack/storage/ceph/backup/CephBackupStorageBase.java (1)
379-423: 新增命令类使用 public 字段，与现有类风格不一致。当前文件中其他命令类（如
GetDownloadProgressCmd、DownloadCmd等）使用 private 字段配合 getter/setter 方法，而新增的DownloadFileCmd、UploadFileCmd、GetDownloadFileProgressCmd及其响应类直接使用 public 字段。建议保持代码风格一致性。🔎 建议修改示例（以 DownloadFileCmd 为例）
public static class DownloadFileCmd extends AgentCommand implements HasThreadContext, Serializable { - public String taskUuid; - public String installPath; + private String taskUuid; + private String installPath; @NoLogging(type = NoLogging.Type.Uri) - public String url; + private String url; @NoLogging(type = NoLogging.Type.Uri) - public String urlScheme; - public long timeout; + private String urlScheme; + private long timeout; @NoLogging(type = NoLogging.Type.Uri) - public String sendCommandUrl; + private String sendCommandUrl; + + // Add getters and setters... }

🧰 Additional context used
📓 Path-based instructions (1)
**/*.java
⚙️ CodeRabbit configuration file
**/*.java: ## 1. API 设计要求
- API 命名：
- API 名称必须唯一，不能重复。
- API 消息类需要继承
APIMessage；其返回类必须继承APIReply或APIEvent，并在注释中用@RestResponse进行标注。- API 消息上必须添加注解
@RestRequest，并满足如下规范：
path:
- 针对资源使用复数形式。
- 当 path 中引用消息类变量时，使用
{variableName}格式。- HTTP 方法对应：
- 查询操作 →
HttpMethod.GET- 更新操作 →
HttpMethod.PUT- 创建操作 →
HttpMethod.POST- 删除操作 →
HttpMethod.DELETE- API 类需要实现
__example__方法以便生成 API 文档，并确保生成对应的 Groovy API Template 与 API Markdown 文件。
2. 命名与格式规范
类名：
- 使用 UpperCamelCase 风格。
- 特殊情况：
- VO/AO/EO 类型类除外。
- 抽象类采用
Abstract或Base前缀/后缀。- 异常类应以
Exception结尾。- 测试类需要以
Test或Case结尾。方法名、参数名、成员变量和局部变量：
- 使用 lowerCamelCase 风格。
常量命名：
- 全部大写，使用下划线分隔单词。
- 要求表达清楚，避免使用含糊或不准确的名称。
包名：
- 统一使用小写，使用点分隔符，每个部分应是一个具有自然语义的英文单词（参考 Spring 框架的结构）。
命名细节：
- 避免在父子类或同一代码块中出现相同名字的成员或局部变量，防止混淆。
- 命名缩写：
- 不允许使用不必要的缩写，如：
AbsSchedulerJob、condi、Fu等。应使用完整单词提升可读性。
3. 编写自解释代码
意图表达：
- 避免使用布尔型参数造成含义不明确。例如：
- 对于
stopAgent(boolean ignoreError)，建议拆分为不同函数（如stopAgentIgnoreError()），或使用枚举表达操作类型。- 命名应尽量用完整的单词组合表达意图，并在名称中体现数据类型或用途（例如在常量与变量名称中，将类型词放在末尾）。
注释：
- 代码应尽量做到自解释，对少于两行的说明可以直接写在代码中。
- 对于较长的注释，需要仔细校对并随代码更新，确保内容正确。
- 接口方法不应有多余的修饰符（例如
public），且必须配有有效的 Javadoc 注释。
4. 流程控制和结构优化
if...else 的使用：
- 应尽量减少 if...else 结构的使用，建议：
- 限制嵌套层级最多为两层，且内层不应再出现
else分支。- 尽早返回（Early Return），将条件判断中的处理逻辑提前结束或抽成独立方法。
- 使用 Java Stream 或 Lambda 表达式代替冗长的循环与条件判断。
条件判断：
- if 条件表达不宜过长或过于复杂，必要时可以将条件抽成 boolean 变量描述。
代码块长度：
- 单个 if 代码块不宜超过一屏显示，以提高可读性和后续维护性。
5. 异常处理与日志
- 捕获异常的原则：
- 对于可以通过预检查避免的 RuntimeException（如
NullPointerException、IndexOutOfBoundsException等），不建议使用 try-catch 来进行处理。- 捕获异常应仅用于处理真正的意外情况，不应将异常逻辑当作正常流程控制。
- 在必要时，应继续抛出异常，使上层业务处理者可以转换为用户友好的错误提示。
- 使用 try-with-resources 语法管理资源，确保在 finally 块中正确关闭资源，并避免在 finally 中返回值。

49-51:isDownloadComplete()方法逻辑可能存在语义问题。当前实现
actualSize > 0 && actualSize == downloadSize，但字段命名可能引起混淆：
actualSize通常表示文件的实际大小downloadSize通常表示已下载的大小如果语义如此，判断下载完成的条件应该是
downloadSize == size或downloadSize >= actualSize。请确认字段语义是否正确，或考虑添加注释说明字段含义。
17-91: LGTM!Getter/setter 方法遵循 Java Bean 规范，实现正确。

缺少 md5sum 字段。

provide its public getter and setter (getMd5sum and setMd5sum) so the
reply.setMd5sum(...) call compiles correctly and follows existing Java bean
style used in this class.

编译错误：GetFileDownloadProgressReply 缺少 md5sum 字段。
第 2171 行调用 reply.setMd5sum(rsp.md5sum)，但 GetFileDownloadProgressReply 类中未定义 md5sum 字段和对应的 setter 方法，这将导致编译失败。
需要在 GetFileDownloadProgressReply 类中添加 md5sum 字段。

around lines 2148 to 2176, the code calls reply.setMd5sum(rsp.md5sum) but
GetFileDownloadProgressReply lacks an md5sum field and setter; modify the
GetFileDownloadProgressReply class to add a private String md5sum field plus
public void setMd5sum(String md5sum) and public String getMd5sum() (or matching
types used by rsp.md5sum), then recompile to ensure the reference is resolved.

缺少消息路由处理
新增了抽象方法 handle(UploadFileToBackupStorageHostMsg msg) 和 handle(GetFileDownloadProgressMsg msg)，但在 handleLocalMessage 方法（Lines 247-289）中未添加对应的消息路由分支。
这将导致这两种消息无法被正确分发到 handle 方法，而是进入 bus.dealWithUnknownMessage(msg) 分支。
🔎 建议在 handleLocalMessage 中添加路由
} else if (msg instanceof GetBackupStorageManagerHostnameMsg) {
handle((GetBackupStorageManagerHostnameMsg) msg);
+ } else if (msg instanceof UploadFileToBackupStorageHostMsg) {
+ handle((UploadFileToBackupStorageHostMsg) msg);

bus.dealWithUnknownMessage(msg);

In storage/src/main/java/org/zstack/storage/backup/BackupStorageBase.java around
lines 125-127 (new abstract methods) and handleLocalMessage around lines
247-289, the two new abstract handlers UploadFileToBackupStorageHostMsg and
GetFileDownloadProgressMsg are not routed and will hit
bus.dealWithUnknownMessage(msg). Add branches in handleLocalMessage that check
for those message types (instanceof UploadFileToBackupStorageHostMsg and
instanceof GetFileDownloadProgressMsg), invoke the corresponding abstract
handle(...) methods, and return after handling so they do not fall through to
the unknown-message branch; also ensure the message classes are imported and any
reply or exception handling follows the existing pattern used for other message
branches.
