第一阶段：单测先行 (Fix Unit Tests) 🧪

目标：优先重构单测代码中的配置初始化逻辑。解决测试环境下的配置注入问题，为后续改动提供验证基准。

• 路由与集群单测
  • cluster/router/condition/router_test.go
• 配置中心单测
  • config_center/apollo/impl_test.go
• 协议与过滤器单测
  • filter/graceful_shutdown/consumer_filter_test.go
  • filter/graceful_shutdown/provider_filter_test.go
  • protocol/dubbo3/common_test.go
  • protocol/grpc/grpc_protocol_test.go
  • protocol/jsonrpc/jsonrpc_protocol_test.go
  • protocol/rest/rest_invoker_test.go
  • protocol/rest/rest_protocol_test.go
• 核心组件单测
  • remoting/nacos/builder_test.go
  • server/action_test.go
  • server/compat_test.go
  • remoting/getty/getty_client_test.go
  • remoting/getty/getty_server_test.go

---

第二阶段：核心底层逻辑迁移 (Core Logic - Config Only Files) 🏗️

目标：在修改 CLI 工具前，必须先将标记为 config only 的非单测核心逻辑迁移至 global。这是确保生成代码能够正常运行的前提。

• 路由配置逻辑重构
  • cluster/router/condition/dynamic_router.go
  • cluster/router/condition/route.go
  • cluster/router/script/router.go
• 配置中心实现重构
  • config_center/zookeeper/impl.go
• 流量治理插件重构
  • filter/hystrix/filter.go
  • filter/polaris/limit/limiter.go
• 协议内部实现迁移
  • protocol/dubbo3/internal/client.go
  • protocol/dubbo3/internal/server.go
  • protocol/grpc/internal/helloworld/client.go
  • protocol/grpc/internal/routeguide/client.go
  • protocol/triple/health/healthServer.go
  • protocol/triple/reflection/serverreflection.go

---

第三阶段：CLI 工具与项目模板迁移 (CLI & Templates) 🛠️

目标：当底层逻辑就绪后，同步更新 dubbogo-cli 及其内置模板，确保新生成的项目天然符合 global 规范。

• 生成器逻辑更新
  • tools/dubbogo-cli/generator/application/cmd.go
  • tools/dubbogo-cli/generator/application/pkg.go
  • tools/dubbogo-cli/generator/sample/gen_client.go
  • tools/dubbogo-cli/generator/sample/gen_server.go
• 项目骨架模板更新
  • tools/dubbogo-cli/cmd/testGenCode/template/newApp/cmd/app.go
  • tools/dubbogo-cli/cmd/testGenCode/template/newApp/pkg/service/service.go
  • tools/dubbogo-cli/cmd/testGenCode/template/newDemo/go-client/cmd/client.go
  • tools/dubbogo-cli/cmd/testGenCode/template/newDemo/go-server/cmd/server.go

---

第四阶段：全面切流与清理 (Full Migration & Cleanup) 🚀

目标：修改剩余的 config+global 混合引用文件，彻底移除对旧 config 包的依赖，最后清理 compat.go。

• 入口与选项文件迁移
  • client/action.go / server/action.go
  • options.go / client/options.go / server/options.go
• 核心协议层最终迁移
  • protocol/dubbo3/dubbo3_invoker.go / dubbo3_protocol.go
  • protocol/triple/server.go / dubbo3_invoker.go
  • protocol/grpc/client.go / server.go
• 注册中心与通信层迁移
  • registry/directory/directory.go / protocol.go
  • remoting/getty/getty_client.go / getty_server.go
• 清理兼容层
  • compat.go / client/compat.go / server/compat.go
