### 配置优先级

1. 命令行参数 (`--spring.datasource.url=...`)
2. 环境变量 (`SPRING_DATASOURCE_URL`)
3. 外部配置文件 (`/opt/mosquito/application-prod.yml`)
4. 内部配置文件 (`classpath:application-prod.yml`)
5. 默认配置 (`application.properties`)

### 日志级别

```yaml
logging:
  level:
    # 根日志级别
    root: INFO

    # 应用日志
    com.mosquito.project: INFO

    # Spring框架
    org.springframework: INFO
    org.springframework.web: INFO
    org.springframework.security: INFO

    # Hibernate
    org.hibernate: INFO
    org.hibernate.SQL: DEBUG
    org.hibernate.type.descriptor.sql.BasicBinder: TRACE

    # Redis
    org.springframework.data.redis: INFO

    # Flyway
    org.flywaydb: INFO
```

## 🌐 环境变量

### 必需环境变量

```bash
# 数据库配置
export DB_URL="jdbc:postgresql://localhost:5432/mosquito_prod"
export DB_USERNAME="mosquito_prod"
export DB_PASSWORD="your_secure_password"

# Redis配置
export REDIS_HOST="localhost"
export REDIS_PORT="6379"
export REDIS_PASSWORD="your_redis_password"

# 安全配置
export API_KEY_ENCRYPTION_KEY="your_32_char_encryption_key_12"
```

### 可选环境变量

```bash
# 速率限制
export RATE_LIMIT_PER_MINUTE="100"

# 日志配置
export LOG_LEVEL="INFO"
export LOG_FILE="/var/log/mosquito/application.log"

# JVM配置
export JAVA_OPTS="-Xms2g -Xmx4g -XX:+UseG1GC"

# Spring配置
export SPRING_PROFILES_ACTIVE="prod"
export SERVER_PORT="8080"
```

### 环境变量文件

创建 `.env` 文件（不要提交到Git）：

```bash
# .env
DB_PASSWORD=your_secure_password
REDIS_PASSWORD=your_redis_password
API_KEY_ENCRYPTION_KEY=your_32_char_encryption_key_12
RATE_LIMIT_PER_MINUTE=100
```

加载环境变量：

```bash
# 使用source加载
source .env

# 或使用export
export $(cat .env | xargs)
```

## 🔧 配置验证

### 启动时验证

```java
@Configuration
public class ConfigValidation {

    @Value("${app.api-key.encryption-key}")
    private String encryptionKey;

    @PostConstruct
    public void validate() {
        if (encryptionKey.length() != 32) {
            throw new IllegalStateException(
                "API key encryption key must be exactly 32 characters"
            );
        }
    }
}
```

### 配置检查命令

```bash
# 检查配置文件语法
java -jar mosquito-1.0.0.jar --spring.config.location=application-prod.yml --spring.profiles.active=prod --debug

# 查看实际配置
java -jar mosquito-1.0.0.jar --spring.profiles.active=prod \
  --spring.boot.admin.client.enabled=false \
  org.springframework.boot.autoconfigure.logging.ConditionEvaluationReportLoggingListener
```
