+## Project Overview
+
+- Project: `kkFileView`
+- Stack: Spring Boot + Freemarker + Redis/Redisson (optional) + JODConverter + front-end preview pages
+- Main module: `server`
+- Default local URL: `http://127.0.0.1:8012/`
+- Production demo: `https://file.kkview.cn/`
+
+This repository is a document preview service. Most user-facing work falls into one of these areas:
+
+1. preview routing and file-type dispatch
+2. conversion pipelines for Office / PDF / CAD / archives / images
+3. Freemarker preview templates under `server/src/main/resources/web`
+4. CI, E2E fixtures, and production deployment automation

+  - `server/src/main/java/cn/keking/service/impl/PdfFilePreviewImpl.java`
+- Archive extraction:
+  - `server/src/main/java/cn/keking/service/CompressFileReader.java`
+
+## Important Templates
+
+- `server/src/main/resources/web/compress.ftl`
+  Archive directory/tree preview page
+- `server/src/main/resources/web/pdf.ftl`
+  PDF preview container page
+- `server/src/main/resources/web/picture.ftl`
+  Single image preview page
+- `server/src/main/resources/web/officePicture.ftl`
+  Office/PDF image-mode preview page
+- `server/src/main/resources/web/officeweb.ftl`
+  Front-end xlsx/html preview page
+
+When debugging UX issues, inspect the exact template selected by the preview flow first. Do not assume two similar preview pages share the same CSS or behavior.
+
+## Local Development
+
+### Recommended dev mode
+
+Use:
+
+```bash
+./server/src/main/bin/dev.sh
+```
+
+This runs Spring Boot with resource hot reload using:
+
+- `spring-boot:run`
+- `-Dspring-boot.run.addResources=true`
+- `server/src/main/config/application.properties`
+
+For front-end template or CSS/JS edits, prefer `dev.sh` over rebuilding jars repeatedly.
+
+### Jar build
+
+```bash
+mvn -q -pl server -DskipTests package
+```
+
+### Main test command used in CI
+
+```bash
+mvn -B package -Dmaven.test.skip=true --file pom.xml
+```
+
+## Configuration Notes
+
+Primary runtime config used by the scripts and defaults committed in this repository:
+
+- `server/src/main/config/application.properties`
+
+Optional environment-specific config:
+
+- `server/src/main/config/test.properties`
+
+Be careful: the repository defaults point at `application.properties`. If a deployment environment explicitly starts the app with `test.properties`, treat that as an environment-specific override rather than the repository default. Always verify the actual startup command before assuming which config file is active.
+
+Examples of config that commonly affects behavior:
+
+- `office.preview.type`
+- `office.preview.switch.disabled`
+- `trust.host`
+- `not.trust.host`
+- `file.upload.disable`
+
+## Preview Behavior Notes
+
+- Office files can render in `pdf` mode or `image` mode.
+- PDF preview uses `pdf.ftl`.
+- Single images use `picture.ftl`.
+- Office image-mode previews use `officePicture.ftl`.
+- Archive previews are not simple file lists; they can load nested previews via the archive UI in `compress.ftl`.
+
+When changing preview defaults, verify both:
+
+1. server-side default config
+2. front-end mode-switch links/buttons
+
+## Archive Preview Notes
+
+Archive preview is a sensitive area because it combines:
+
+- directory tree generation
+- extraction to disk
+- nested preview URL construction
+- inline iframe loading
+
+If an archive-contained Office file gets stuck on loading:
+
+1. verify the extracted file on disk is not corrupted
+2. verify conversion output exists
+3. verify the preview template points to the correct generated artifact
+4. verify the running Office manager / LibreOffice process is healthy
+
+Do not assume “loading forever” is a front-end issue.
+
+## Testing
+
+### Targeted Java tests
+
+Example targeted test:
+
+```bash
+mvn -q -pl server -Dtest=PdfViewerCompatibilityTests test
+```
+
+### E2E tests
+
+See:
+
+- `tests/e2e/README.md`
+
+PR E2E currently covers:
+
+- common preview smoke tests
+- Office smoke tests
+- archive smoke tests
+- basic security and performance checks
+
+## CI / Deployment
+
+### CI
+
+- `maven.yml`
+  - builds on `push` to `master`
+  - builds on PRs targeting `master`
+- `pr-e2e-mvp.yml`
+  - runs E2E on PRs to `master`
+
+### Production deployment
+
+- `master-auto-deploy.yml`
+  - triggers on push to `master`
+  - deploys to Windows over WinRM
+
+Deployment script:
+
+- `.github/scripts/remote_windows_deploy.ps1`
+
+Important operational detail:
+
+- the committed `bin/startup.bat` in this repo points at `..\config\application.properties`
+- if production uses a different config file, treat that as an out-of-repo server override rather than a repository default
+
+If a production config change “does not take effect”, inspect the actual startup command or deployed `startup.bat` on the server first and verify which config file path it is using.
+
+## Working Conventions For Agents
+
+- Prefer minimal, targeted changes over wide refactors.
+- Inspect the active preview template before editing CSS.
+- Verify whether behavior is controlled by config, back-end routing, or front-end template logic before changing code.
+- For production/debug tasks, distinguish clearly between:
+  - repository source defaults
+  - deployed server config
+  - runtime process arguments
+- When changing defaults, mention whether the change affects:
+  - local dev only
+  - repository default config
+  - deployed server config
+  - existing query-param overrides
+
+## Suggested Validation Checklist
+
+For preview-related changes, validate as many of these as apply:
+
+1. target URL returns `200`
+2. selected template is the expected one
+3. generated intermediate artifacts exist when required
+4. target UI element or style change is actually present in rendered HTML
+5. targeted Java test passes
+6. relevant E2E path is still compatible
+
+## Non-Goals
+
+This file is not a replacement for user-facing product documentation. Keep it focused on helping coding agents navigate the codebase and make correct changes faster.

+
+当前线上 Windows 服务器的实际部署信息如下：
+
+- 部署根目录：`C:\kkFileView-5.0`
+- 运行 jar：`C:\kkFileView-5.0\bin\kkFileView-<当前项目版本>.jar`
+- 启动脚本：`C:\kkFileView-5.0\bin\startup.bat`
+- 运行配置：`C:\kkFileView-5.0\config\test.properties`
+- 健康检查地址：`http://127.0.0.1:8012/`
+
+当前自动部署链路采用服务器拉最新源码并本机编译的方式：
+
+1. 通过 WinRM 连接 Windows 服务器
+2. 在服务器上的源码目录执行 `git fetch/reset/clean`，同步到 `origin/$KK_DEPLOY_BRANCH`（默认 `master`）
+3. 使用服务器上的 JDK 21 和 Maven 执行 `mvn clean package -Dmaven.test.skip=true`
+4. 备份线上 jar，替换为新构建产物
+5. 使用现有 `startup.bat` 重启，并做健康检查
+6. 如果健康检查失败，则自动回滚旧 jar 并重新拉起
+
+## 需要配置的 GitHub Secrets
+
+- `KK_DEPLOY_HOST`
+- `KK_DEPLOY_USERNAME`
+- `KK_DEPLOY_PASSWORD`
+
+以下部署参数当前由 workflow 从 GitHub Secrets 读取；如果未单独配置，则使用脚本默认值：

+- `KK_DEPLOY_ROOT=C:\kkFileView-5.0`
+- `KK_DEPLOY_HEALTH_URL=http://127.0.0.1:8012/`
+
+下面这些非敏感参数可以通过 workflow env 或 GitHub Variables 覆盖；未配置时会使用默认值：

+- `KK_DEPLOY_BRANCH=master`
+- `KK_DEPLOY_SOURCE_ROOT=C:\kkFileView-source`
+- `KK_DEPLOY_JAVA_HOME=C:\Program Files\jdk-21.0.2`
+- `KK_DEPLOY_GIT_EXE=C:\kkFileView-tools\git\cmd\git.exe`
+- `KK_DEPLOY_MVN_CMD=C:\kkFileView-tools\maven\bin\mvn.cmd`
+- `KK_DEPLOY_MAVEN_SETTINGS=`
+
+如果服务器到 GitHub 的拉取速度不稳定，也可以把 `KK_DEPLOY_REPO_URL` 改成你自己的 Git 镜像地址。
+如果服务器访问 Maven Central 不稳定，也可以通过 `KK_DEPLOY_MAVEN_SETTINGS` 指向自定义 `settings.xml`，切换到就近镜像仓库。
+
+## 服务器前置环境
+
+服务器需要具备以下工具：
+
+- Git for Windows（推荐安装在 `C:\kkFileView-tools\git`）
+- Apache Maven 3.9.x（推荐安装在 `C:\kkFileView-tools\maven`）
+- JDK 21（当前线上已存在：`C:\Program Files\jdk-21.0.2`）
+
+## Workflow
+
+新增 workflow：`.github/workflows/master-auto-deploy.yml`
+
+- 触发条件：`push` 到 `master`，或手动 `workflow_dispatch`
+- 部署方式：WinRM + 服务器源码同步 + 服务器本机 Maven 编译 + jar 替换/回滚

-            【http/https 流资源文件预览】很多系统内不是直接暴露文件下载地址，而是请求通过id、code等参数到通过统一的接口，后端通过id或code等参数定位文件，再通过OutputStream输出下载，此时下载url是不带文件后缀名的，预览时需要拿到文件名，传一个参数fullfilename=xxx.xxx来指定文件名，示例如下
