-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-Java API code generator that generates JAX-RS (CXF) and Spring MVC code from YAML definitions. Generates Controller, Request, and Response classes with JSR-303 validation annotations.
-
-## Project Structure
-
-This repository contains **ONE** project, with a **separate IntelliJ plugin project**:
-
-| Location | Type | Build System | Java Version |
-|----------|------|--------------|--------------|
-| `D:\idea\workSpace\api-codegen\` | Main Project | Maven | Java 21 |
-| `D:\idea\workSpace\api-codegen-intellij-standalone\` | IntelliJ Plugin | Gradle | Java 17 |
-
-**Important:** The IntelliJ plugin is in a SEPARATE directory and is a separate Git repository.
-
-## Developer Workflow
-
-```
-1. Design API in YAML (api.yaml)
-2. Configure output paths (codegen-config.yaml)
-3. Run: mvn api-codegen:generate
-4. Copy Controller → add business logic
-5. Req/Rsp auto-overwrite on re-run
-```
-
-## Requirements
-
-- **JDK 21** (required for running the core module)
-- **IntelliJ IDEA SDK** (automatically available when developing the plugin)
-- **JDK 17** (for building the IntelliJ plugin)
-
-## Build Commands
-
-```bash
-# Set JDK 21 environment (required)
-export JAVA_HOME="C:/Program Files/Java/jdk-21.0.10"
-export PATH="$JAVA_HOME/bin:$PATH"
-
-# Build entire project (core + maven plugin)
-mvn clean install
-
-# Build just core module
-cd api-codegen-core && mvn clean install
-
-# Run tests
-mvn test
-
-# Run a single test
-mvn test -Dtest=TestClassName
-```
-
-## Testing Requirements
-
-**Core Principle: Maven Backend is the Source of Truth**
-
-All business logic must be implemented in the Maven backend first. Extensions (plugin, web UI) must follow the Maven logic.
-
-### Running All Tests
-
-```bash
-# Windows
-run-all-tests.bat
-
-# Linux/Mac
-bash run-all-tests.sh
-```
-
-### Test Coverage
-
-| Module | Test File | Tests |
-|--------|-----------|-------|
-| Maven Backend | api-codegen-core/src/test/ | 130 tests |
-| Web UI Analyzer | web-ui/test/analyzer-test.js | 41 tests |
-| Web UI Diff | web-ui/test/diff-test.js | 13 tests |
-| Web UI Render | web-ui/test/render-test.js | 16 tests |
-
-### Git Pre-commit Hook (Optional)
-
-To enable automatic testing before each commit:
-
-```bash
-# Install hook
-cp git-hooks/pre-commit .git/hooks/pre-commit
-chmod +x .git/hooks/pre-commit
-
-# Remove hook
-rm .git/hooks/pre-commit
-```
-
-### BDD Format Tests
-
-All unit tests must use **BDD (Behavior-Driven Development) format**:
-
-```java
-@DisplayName("ValidationAnalyzer 校验分析")
-class ValidationAnalyzerTest {
-
-    @Nested
-    @DisplayName("分析 String 类型字段")
-    class AnalyzeStringField {
-
-        @Test
-        @DisplayName("应检测到缺少长度校验")
-        void shouldDetectMissingLengthValidation() {
-            // given: String 字段无校验规则
-            FieldDefinition field = new FieldDefinition();
-            field.setName("username");
-            field.setType("String");
-
-            // when: 执行分析
-            List<ValidationError> errors = analyzer.analyze(api);
-
-            // then: 应报告缺少长度校验
-            assertThat(errors).anyMatch(e -> e.getCode().equals("DFX-004"));
-        }
-    }
-}
-```
-
-### Coverage Requirements
-
-| Requirement | Description |
-|-------------|-------------|
-| **All Scenarios** | Every validation rule (DFX-001 to DFX-014) must have test cases |
-| **All Branches** | All if/else, switch-case branches must be covered |
-| **Boundary Conditions** | min/max, minLength/maxLength boundaries must be tested |
-| **Positive+Negative** | Both valid and invalid inputs must be tested |
-
-### Test Matrix for DFX Rules
-
-Each DFX rule must cover:
-
-| DFX Code | Positive (No Error) | Negative (Has Error) | Boundary |
-|----------|---------------------|---------------------|----------|
-| **Path** |
-| DFX-001 | Path without // | Path with // | Multiple // |
-| DFX-002 | Path starts with / | Path doesn't start with / | Empty path |
-| **Parameters** |
-| DFX-003 | Required has @NotNull | Required without @NotNull | Optional + @NotNull |
-| DFX-011 | page has range | page without range | boundary 1/2147483647 |
-| DFX-012 | size has range | size without range | boundary 1/100 |
-| DFX-014 | Path param has validation | Path param without validation | Mixed types |
-| **Fields** |
-| DFX-004 | String has validation | String without validation | Only minLength |
-| DFX-005 | email has @Email | email without @Email | Wrong format |
-| DFX-006 | phone has pattern | phone without pattern | Wrong regex |
-| DFX-007 | Number has min/max | Number without range | Only min or only max |
-| DFX-008 | List has minSize | List without size | minSize > maxSize |
-
-**Important:** Do not infer types from field names. Preserve user's original type definition.
-
-## Running the Maven Plugin
-
-**First, ensure JDK 21 is set:**
-```bash
-export JAVA_HOME="C:/Program Files/Java/jdk-21.0.10"
-export PATH="$JAVA_HOME/bin:$PATH"
-```
-
-**Then run the plugin:**
-```bash
-# Use full groupId (recommended)
-mvn com.apicgen:api-codegen-maven-plugin:generate
-
-# Or use short form (after plugin is installed to local repo)
-mvn api-codegen:generate
-
-# Force overwrite existing files
-mvn com.apicgen:api-codegen-maven-plugin:generate -Dforce=true
-
-# With custom YAML path and output dir
-mvn com.apicgen:api-codegen-maven-plugin:generate -DyamlFile=src/main/resources/api.yaml
-
-# With custom base package
-mvn com.apicgen:api-codegen-maven-plugin:generate -DbasePackage=com.example.api
-
-# With custom company name
-mvn com.apicgen:api-codegen-maven-plugin:generate -Dcompany="MyCompany"
-
-# With custom config file
-mvn com.apicgen:api-codegen-maven-plugin:generate -DconfigFile=custom-config.yaml
-```
-
-## Output Strategy
-
-| File Type | Path | Overwrite | Usage |
-|-----------|------|-----------|-------|
-| Controller | `generated/api/` | NO | Copy to project, add business logic |
-| Request | `src/main/java/req/` | YES | Auto-overwrite, never edit manually |
-| Response | `src/main/java/rsp/` | YES | Auto-overwrite, never edit manually |
-
-**Why this design:**
-- Re-running `mvn api-codegen:generate` won't break your code
-- Controller is separated to avoid accidental overwrites of business logic
-- Req/Rsp are regenerated from YAML - they are derived artifacts
-
-## Example: Adding a New API
-
-### Step 1: Create API Design (api.yaml)
-
-```yaml
-apis:
-  - name: createUser
-    path: /api/users
-    method: POST
-    description: Create a new user
-    request:
-      className: CreateUserReq
-      fields:
-        - name: username
-          type: String
-          required: true
-          description: Username
-          validation:
-            minLength: 4
-            maxLength: 20
-            pattern: "^[a-zA-Z0-9_]+$"
-        - name: email
-          type: String
-          required: true
-          description: User email
-          validation:
-            email: true
-    response:
-      className: CreateUserRsp
-      fields:
-        - name: userId
-          type: Long
-          description: Created user ID
-        - name: success
-          type: Boolean
-          description: Operation result
-```
-
-### Step 2: Configure (codegen-config.yaml)
-
-```yaml
-copyright:
-  company: ""
-  startYear: 2024
-
-output:
-  controller:
-    path: src/main/java/com/example/api/controller/
-  request:
-    path: src/main/java/com/example/req/
-  response:
-    path: src/main/java/com/example/rsp/
-```
-
-### Step 3: Run and Use
-
-```bash
-mvn api-codegen:generate
-```
-
-**Output:**
-```
-generated/api/com/example/api/controller/CreateController.java
-src/main/java/com/example/req/com/example/req/CreateUserReq.java
-src/main/java/com/example/rsp/com/example/rsp/CreateUserRsp.java
-```
-
-**Next:**
-1. Copy `CreateController.java` to your project
-2. Implement the business logic
-3. When API changes, re-run `mvn api-codegen:generate -Dforce=true`
-4. Req/Rsp are auto-updated, re-copy Controller if needed
-
-## Running Standalone
-
-**Prerequisites:** JDK 21
-
-```bash
-# First build the project
-export JAVA_HOME="C:/Program Files/Java/jdk-21.0.10"
-export PATH="$JAVA_HOME/bin:$PATH"
-mvn clean install -DskipTests
-
-# Then run standalone using Maven exec plugin (includes dependencies)
-cd api-codegen-core
-mvn exec:java -Dexec.mainClass="com.apicgen.Main" -Dexec.args="api-example.yaml"
-
-# Or run directly with all dependencies (requires classpath with all JARs)
-java -cp "target/api-codegen-core-1.0.0.jar;target/dependency/*" com.apicgen.Main api-example.yaml
-```
-
-**Note:** Direct `java -cp` requires all dependencies (Jackson, JavaPoet, etc.) in the classpath. Using `mvn exec:java` is recommended as it handles dependencies automatically.
-
-## Architecture
-
-Multi-module Maven project with two modules:
-
-### `api-codegen-core` (Core Library)
-
-- **model/**: Data models (`ApiDefinition`, `Api`, `ClassDefinition`, `FieldDefinition`, `ValidationConfig`)
-- **parser/**: YAML parsing using Jackson/YAMLFactory (`YamlParser`)
-- **validator/**: Validates YAML definitions (`ApiValidator` enforces DFX rules, circular references)
-- **generator/**: Code generation framework
-  - `CodeGenerator` interface: `generateController()`, `generateRequest()`, `generateResponse()`
-  - `CodeGeneratorFactory`: Factory for code generators
-  - `spring/SpringCodeGenerator`: Spring MVC implementation (@PathVariable, @RequestParam, etc.)
-  - `cxf/CxfCodeGenerator`: JAX-RS implementation (@PathParam, @QueryParam, etc.)
-- **config/**: Configuration loaded from `codegen-config.yaml`
-- **util/**: `CodeGenUtil` with utility methods
-
-### `api-codegen-maven-plugin` (Maven Plugin)
-
-- `ApiCodegenMojo`: Executes at `GENERATE_SOURCES` phase
-- Parameters: `yamlFile`, `outputDir`, `basePackage`, `company`, `startYear`, `openapi`, `force`, `configFile`
-- Configuration file `codegen-config.yaml` can be overridden by CLI parameters
-
-## YAML Schema
-
-This tool supports **two YAML formats**:
-
-### 1. Custom API Format (Internal Use)
-
-```yaml
-apis:
-  - name: createUser          # API method name
-    path: /api/users           # Must start with /
-    method: POST               # GET/POST/PUT/DELETE/PATCH
-    description: API description
-    request:
-      className: CreateUserReq
-      fields:
-        - name: username
-          type: String         # String, Integer, Long, Double, Boolean, LocalDate, LocalDateTime, List<T>, Enum, or custom object
-          required: true
-          description: Field description
-          validation:
-            minLength: 4
-            maxLength: 20
-            pattern: "^[a-zA-Z0-9_]+$"
-            email: true        # For String types
-            min: 0             # For numeric types (DFX: default 0)
-            max: 100           # For numeric types (required)
-            minSize: 1         # For List types
-            maxSize: 10        # For List types (DFX: must be > 0)
-            elementValidation: # For List element types
-              minLength: 2
-              maxLength: 10
-            past: true         # For date types
-            future: true       # For date types
-          enumValues: [ADMIN, USER]  # Required for Enum type (generates String field)
-          fields:              # For nested object types
-            - name: nestedField
-              type: String
-              required: false
-    response:
-      className: CreateUserRsp
-      fields:
-        - name: userId
-          type: Long
-          description: User ID
-```
-
-### 2. Swagger / OpenAPI Format (Recommended)
-
-The tool automatically converts Swagger 2.0 and OpenAPI 3.0 formats to internal format:
-
-```yaml
-# Swagger 2.0
-swagger: "2.0"
-info:
-  title: User API
-  version: "1.0"
-paths:
-  /users:
-    get:
-      summary: Query users
-      operationId: queryUsers
-      parameters:
-        - name: page
-          in: query
-          description: Page number
-          schema:
-            type: integer
-      responses:
-        200:
-          description: Success
-
-# OpenAPI 3.0
-openapi: "3.0.0"
-info:
-  title: User API
-  version: "1.0"
-paths:
-  /users:
-    get:
-      operationId: queryUsers
-      parameters:
-        - name: page
-          in: query
-          schema:
-            type: integer
-      responses:
-        200:
-          description: Success
-```
-
-## Validation Auto-Fix Rules
-
-The analyzer automatically adds validation rules for Swagger/OpenAPI parameters:
-
-### Parameter Types
-| Location | Swagger `in` value | Generated Annotation |
-|----------|-------------------|---------------------|
-| Path | `path` | `@PathParam` |
-| Query | `query` | `@QueryParam` |
-| Header | `header` | `@HeaderParam` |
-| Cookie | `cookie` | `@CookieParam` |
-| Body | `body` | `@RequestBody` |
-
-### String Parameters
-| Field Pattern | Validation Added |
-|--------------|-----------------|
-| Contains `email`, `mail` | `pattern` (email regex) |
-| Contains `phone`, `mobile` | `pattern` (phone regex: `^(\\+86\|86)?1[3-9]\\d{9}$`) |
-| Contains `url`, `link` | `pattern` (URL regex) |
-| Default | `minLength=1, maxLength=255` |
-
-### Integer/Number Parameters
-| Field Pattern | Validation Added |
-|--------------|-----------------|
-| `page`, `pageNum` | `minimum=1, maximum=2147483647` |
-| Contains `size`, `limit` | `minimum=1, maximum=100` |
-| Contains `age` | `minimum=0, maximum=150` |
-| Contains `score`, `rate` | `minimum=0, maximum=100` |
-| Contains `price`, `amount`, `total` | `minimum=0` |
-| Path parameters | `minimum=1` |
-| Default (not id) | `minimum=0, maximum=2147483647` |
-
-### Required Parameters
-| Parameter Type | Annotation |
-|---------------|------------|
-| String required | `@NotBlank` |
-| Other required | `@NotNull` |
-
-### Other Auto-Fixes
-- `required=true` parameters → adds `@NotNull` / `@NotBlank` annotation
-- Path with `//` → removes duplicate slashes
-- Path with `/XXX/` prefix → removes placeholder prefix
-- Missing `description` → adds description from field name
-- Missing `operationId` → generates from summary
-
-### DFX Rule Codes
-| Code | Rule | Description |
-|------|------|-------------|
-| **Path** |
-| DFX-001 | Path规范 | Cannot contain duplicate slashes |
-| DFX-002 | Path规范 | Must start with / |
-| **Parameters** |
-| DFX-003 | 必填校验 | required=true must add notNull/notBlank |
-| DFX-011 | 分页校验 | page/pageNum needs min:1,max:2147483647 |
-| DFX-012 | 分页校验 | pageSize/limit/size needs min:1,max:100 |
-| DFX-014 | 路径校验 | Path parameter needs min:1 or minLength:1 |
-| **Fields** |
-| DFX-004 | 字符串校验 | String type needs length or format validation |
-| DFX-005 | 邮箱校验 | email format needs @Email |
-| DFX-006 | 电话校验 | phone field needs regex |
-| DFX-007 | 数值校验 | Numeric type needs min/max range |
-| DFX-008 | 集合校验 | List type needs minSize/maxSize |
-
-## Configuration File (`codegen-config.yaml`)
-
-```yaml
-copyright:
-  company: ""            # Company name (empty to omit from copyright header)
-  startYear: 2024
-
-openapi:
-  enabled: false
-  version: "3.0"
-
-output:
-  controller:
-    path: generated/api/    # Controllers (manual copy)
-  request:
-    path: src/main/java/req/ # Requests (auto-overwrite)
-  response:
-    path: src/main/java/rsp/ # Responses (auto-overwrite)
-```
-
-## Key Design Notes
-
-1. **Unified Controller (v1.1.0+)**: One YAML file → one Controller class (e.g., `ExampleApi` for `basePackage=com.example.api`). All API methods grouped in single class.
-
-2. **Output Strategy**: Controllers go to `generated/api/` (user copies manually), Request/Response classes go to `src/main/java/req/` and `src/main/java/rsp/` (auto-overwrite, no manual edits)
-
-3. **Framework Support**:
-   - Code generator supports both Spring MVC and JAX-RS (CXF) annotations by default
-   - No need to configure framework type, the output works with both frameworks
-
-4. **Custom Annotations**: Configure in `codegen-config.yaml`:
-   ```yaml
-   customAnnotations:
-     classAnnotations: ["@Secured", "@AuditLog"]
-     methodAnnotations: ["@Permission(\"default\")"]
-   ```
-
-5. **DFX Principles**: Validator enforces defensive rules:
-   - `maxSize` must be > 0 (error)
-   - `min` should be >= 0 (warning)
-   - `minLength` cannot exceed `maxLength`
-   - `minSize` cannot exceed `maxSize`
-
-6. **Circular Reference Detection**: `CodeGenUtil.hasCircularReference()` uses visited set tracking
-
-7. **Controller Naming Convention**: Based on API name prefix:
-   - `create*` → `CreateController`
-   - `update*` → `UpdateController`
-   - `delete*` → `DeleteController`
-   - `query*`, `get*` → `QueryController`
-   - otherwise → `{CapitalizedName}Controller`
-
-8. **Enum Handling**: `type: Enum` generates a `String` field with `enumValues` as documentation
-
-## Web UI (`web-ui/`)
-
-Browser-based YAML editor with real-time validation, auto-fix, and code preview.
-
-```bash
-# Start local server
-cd web-ui && npx serve -l 8080
-# Or simply open web-ui/index.html in browser
-
-# Run all tests
-cd web-ui && npm test
-```
-
-**Key files:**
-- `index.html` - Main UI
-- `js/analyzer.js` - YAML analysis logic (mirrors Java validator rules)
-- `test/analyzer-test.js` - 37 unit tests for analyzer
-- `test/render-test.js` - 16 unit tests for UI rendering
-
-**Features:**
-- CodeMirror YAML editor with syntax highlighting
-- Real-time validation analysis
-- Auto-fix for validation rules
-- Diff preview showing before/after code
-- Supports Swagger 2.0 and OpenAPI 3.0 formats
-
-## IntelliJ IDEA Plugin Development
-
-**Location:** `D:\idea\workSpace\api-codegen-intellij-standalone\` (SEPARATE Git repository)
-
-**Why separate?** IntelliJ Platform SDK requires Gradle + Java 17, not available in Maven Central.
-
-### Before Developing the Plugin
-
-1. Install core module: `mvn install -DskipTests -pl api-codegen-core`
-2. Open `D:\idea\workSpace\api-codegen-intellij-standalone\` as Gradle project
-3. Configure SDK: IntelliJ IDEA (IU/IC-241.0), Language level: 17
-4. Run: Right-click `ApiCodegenPlugin.java` > `Run Plugin`
-
-### Plugin Structure
