[Feature][Linkis] Replace Tomcat & Jetty with BES (BaoLanDe) middleware solution

Start by reviewing Linkis's current Tomcat/Jetty deployment packaging and container-specific code in linkis-dist. Assess Servlet 3.0+/4.0, WebSocket, classloader, and Spring Boot external-container compatibility on BES. Done means BES-compatible deployment packages, all services validated on BES, existing deployments retained, and migration documentation published.

Linkis Component

linkis-dist

What happened

English:

Linkis currently uses Tomcat and Jetty as servlet containers. For domestic localization requirements, there is a need to support BES (BaoLanDe/宝兰德) middleware as an alternative container solution.

Background:
BES (BaoLanDe) is a domestic middleware solution commonly required in Chinese government and enterprise environments for localization (信创) compliance. Supporting BES would enable Linkis deployment in these environments.

中文:

Linkis当前使用Tomcat和Jetty作为servlet容器。为满足国产化需求，需要支持宝兰德(BES)中间件作为替代容器解决方案。

背景:
宝兰德(BES)是中国政府和企业环境中国产化(信创)合规常见要求的国产中间件解决方案。支持宝兰德将使Linkis能够在这些环境中部署。

What you expected to happen

English:

Linkis should support BES middleware as a servlet container option:

1. Provide BES-compatible deployment packages
2. Ensure all Linkis services can run on BES container
3. Maintain compatibility with existing Tomcat/Jetty deployments
4. Provide migration guide from Tomcat/Jetty to BES

中文:

Linkis应该支持宝兰德中间件作为servlet容器选项：

1. 提供与宝兰德兼容的部署包
2. 确保所有Linkis服务都能在宝兰德容器上运行
3. 保持与现有Tomcat/Jetty部署的兼容性
4. 提供从Tomcat/Jetty迁移到宝兰德的指南

How to reproduce

English:
Current situation:

1. Linkis services are packaged for Tomcat/Jetty deployment
2. BES middleware deployment is not officially supported
3. Manual adaptation is required for BES deployment

中文:
当前情况：

1. Linkis服务打包用于Tomcat/Jetty部署
2. 不正式支持宝兰德中间件部署
3. 需要手动适配才能部署到宝兰德

Anything else

English:

Implementation Approach:

1. Container Abstraction: Abstract servlet container dependencies to support multiple implementations
2. BES Compatibility Testing: Test Linkis services on BES Application Server
3. Build System Updates: Add BES-specific build profiles in Maven/Gradle
4. Dependency Management: Handle BES-specific dependencies and APIs
5. Documentation: Create BES deployment guide

Technical Considerations:

• Servlet API compatibility (ensure using standard Servlet 3.0+/4.0 APIs)
• WebSocket support verification on BES
• Spring Boot embedded container vs external container deployment
• ClassLoader isolation issues
• BES-specific configuration requirements

BES Middleware Information:

• Official Website: http://www.bessystem.com/
• Supports JEE standards (Servlet, JSP, EJB, etc.)
• Compatible with mainstream application servers

Migration Steps:

1. Review current Tomcat/Jetty specific code
2. Replace with standard Servlet APIs
3. Test on BES Application Server
4. Create BES deployment WAR/EAR packages
5. Update deployment documentation

实现方法:

1. 容器抽象：抽象servlet容器依赖以支持多种实现
2. 宝兰德兼容性测试：在宝兰德应用服务器上测试Linkis服务
3. 构建系统更新：在Maven/Gradle中添加宝兰德特定的构建配置文件
4. 依赖管理：处理宝兰德特定的依赖和API
5. 文档：创建宝兰德部署指南

技术考虑:

• Servlet API兼容性（确保使用标准Servlet 3.0+/4.0 API）
• 在宝兰德上验证WebSocket支持
• Spring Boot嵌入式容器vs外部容器部署
• ClassLoader隔离问题
• 宝兰德特定的配置要求

宝兰德中间件信息:

• 官方网站：http://www.bessystem.com/
• 支持JEE标准（Servlet、JSP、EJB等）
• 兼容主流应用服务器

迁移步骤:

1. 审查当前Tomcat/Jetty特定代码
2. 替换为标准Servlet API
3. 在宝兰德应用服务器上测试
4. 创建宝兰德部署WAR/EAR包
5. 更新部署文档
