# Multi-Module Architecture Refactor Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 将 novalon-manage-api 从单体模块重构为网关 + 单体多模块架构，实现模块化、统一认证授权、独立部署和性能优化。

**Architecture:** 采用网关（manage-gateway）+ 应用层（manage-app）+ 业务模块（manage-sys、manage-audit、manage-notify、manage-file）+ 公共模块（manage-common、manage-db）的分层架构。网关统一处理JWT认证、RBAC权限和限流熔断，应用层聚合所有业务模块，通过Caffeine缓存优化性能，使用Docker容器化部署。

**Tech Stack:** Java 21, Spring Boot 3.4.1, Spring WebFlux, Spring Security, R2DBC, PostgreSQL, JWT, Caffeine, Docker, Maven

## Phase 1: Preparation (1-2 days)

### Task 1: Create manage-gateway module structure

**Files:**
- Create: `novalon-manage-api/manage-gateway/pom.xml`
- Create: `novalon-manage-api/manage-gateway/src/main/java/cn/novalon/manage/gateway/GatewayApplication.java`
- Create: `novalon-manage-api/manage-gateway/src/main/resources/application.yml`
- Create: `novalon-manage-api/manage-gateway/src/main/resources/application-dev.yml`
- Create: `novalon-manage-api/manage-gateway/src/main/resources/application-prod.yml`
- Create: `novalon-manage-api/manage-gateway/Dockerfile`

**Step 1: Create manage-gateway pom.xml**

```

**Step 2: Create GatewayApplication.java**

```java
package cn.novalon.manage.gateway;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class GatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(GatewayApplication.class, args);
    }

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route("manage-app", r -> r
                        .path("/api/**")

                .build();
    }
}
```

**Step 4: Compile and verify**

Run: `cd novalon-manage-api && mvn clean compile -pl manage-gateway -am`

# JWT Configuration
JWT_SECRET=your_jwt_secret_key_minimum_256_bits
JWT_EXPIRATION=7200

# Spring Profile

**Step 3: Commit**

```bash
git add novalon-manage-system/docker-compose.yml novalon-manage-system/.env.example
git commit -m "feat: add Docker Compose configuration"

## Phase 4: Testing and Optimization (2-3 days)

### Task 19: Write unit tests for manage-common

**Files:**
- Create: `novalon-manage-api/manage-common/src/test/java/cn/novalon/manage/common/util/JwtTokenProviderTest.java`
- Create: `novalon-manage-api/manage-common/src/test/java/cn/novalon/manage/common/service/TokenBlacklistServiceTest.java`

**Step 1: Write JwtTokenProviderTest**

Create: `novalon-manage-api/manage-common/src/test/java/cn/novalon/manage/common/util/JwtTokenProviderTest.java`

```java
package cn.novalon.manage.common.util;

import cn.novalon.manage.common.config.JwtProperties;
import cn.novalon.manage.common.dto.JwtUser;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import java.util.Arrays;
import java.util.List;

import static org.junit.jupiter.api.Assertions.*;

class JwtTokenProviderTest {

    private JwtTokenProvider jwtTokenProvider;
    private JwtProperties jwtProperties;

    @BeforeEach
    void setUp() {
        jwtProperties = new JwtProperties();
        jwtProperties.setSecret("test-secret-key-for-testing-purposes-only");
        jwtProperties.setExpiration(7200);
        jwtTokenProvider = new JwtTokenProvider(jwtProperties);
    }

    @Test
    void testGenerateToken() {
        JwtUser user = new JwtUser();
        user.setUserId("user123");
        user.setUsername("testuser");
        user.setRoles(Arrays.asList("ADMIN"));
        user.setPermissions(Arrays.asList("user:read", "user:write"));

        String token = jwtTokenProvider.generateToken(user);

        assertNotNull(token);
        assertFalse(token.isEmpty());
    }

    @Test
    void testParseToken() {
        JwtUser originalUser = new JwtUser();
        originalUser.setUserId("user123");
        originalUser.setUsername("testuser");
        originalUser.setRoles(Arrays.asList("ADMIN"));
        originalUser.setPermissions(Arrays.asList("user:read", "user:write"));

        String token = jwtTokenProvider.generateToken(originalUser);
        JwtUser parsedUser = jwtTokenProvider.parseToken(token);

        assertEquals(originalUser.getUserId(), parsedUser.getUserId());
        assertEquals(originalUser.getUsername(), parsedUser.getUsername());
        assertEquals(originalUser.getRoles(), parsedUser.getRoles());
        assertEquals(originalUser.getPermissions(), parsedUser.getPermissions());
    }

    @Test
    void testValidateToken() {
        JwtUser user = new JwtUser();
        user.setUserId("user123");
        user.setUsername("testuser");
        user.setRoles(Arrays.asList("ADMIN"));
        user.setPermissions(Arrays.asList("user:read"));

        String validToken = jwtTokenProvider.generateToken(user);
        assertTrue(jwtTokenProvider.validateToken(validToken));

        String invalidToken = "invalid.token.here";
        assertFalse(jwtTokenProvider.validateToken(invalidToken));
    }
}
```

**Step 2: Write TokenBlacklistServiceTest**

Create: `novalon-manage-api/manage-common/src/test/java/cn/novalon/manage/common/service/TokenBlacklistServiceTest.java`

```java
package cn.novalon.manage.common.service;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.*;

class TokenBlacklistServiceTest {

    private TokenBlacklistService tokenBlacklistService;

    @BeforeEach
    void setUp() {
        tokenBlacklistService = new TokenBlacklistService();
    }

    @Test
    void testAddToBlacklist() {
        String tokenId = "token123";
        tokenBlacklistService.addToBlacklist(tokenId);

        assertTrue(tokenBlacklistService.isBlacklisted(tokenId));
    }

    @Test
    void testIsBlacklisted() {
        String tokenId = "token456";
        assertFalse(tokenBlacklistService.isBlacklisted(tokenId));

        tokenBlacklistService.addToBlacklist(tokenId);
        assertTrue(tokenBlacklistService.isBlacklisted(tokenId));
    }

    @Test
    void testMultipleTokens() {
        String token1 = "token1";
        String token2 = "token2";
        String token3 = "token3";

        tokenBlacklistService.addToBlacklist(token1);
        tokenBlacklistService.addToBlacklist(token2);
        tokenBlacklistService.addToBlacklist(token3);

        assertTrue(tokenBlacklistService.isBlacklisted(token1));
        assertTrue(tokenBlacklistService.isBlacklisted(token2));
        assertTrue(tokenBlacklistService.isBlacklisted(token3));
    }
}
```

**Step 3: Run tests**

Run: `cd novalon-manage-api && mvn test -pl manage-common`

Expected: All tests pass

**Step 4: Commit**

```bash
