从GitHub Trending SQL Bug看ORM框架陷阱：Java开发者如何构建可靠的AI技术选型体系

// MyBatis Plus 3.5.x版本中的别名处理逻辑（简化版）
protected String columnToString(SFunction<T, ?> column) {
    // 获取实体类字段名
    String fieldName = getColumnCache().getColumn(column);
    // 应用表别名前缀
    if (StringUtils.isNotBlank(tableAlias)) {
        return tableAlias + "." + fieldName;
    }
    return fieldName;
}

// Spring AI的核心组件架构
@Configuration
public class SpringAIConfig {
    
    @Bean
    public ChatClient chatClient(ChatModel chatModel) {
        return new AiChatClient(chatModel);
    }
    
    @Bean
    public PromptTemplate promptTemplate() {
        return new PromptTemplate("{{question}}");
    }
    
    // 支持多种AI模型提供商的抽象层
    @Bean
    @ConditionalOnProperty(name = "spring.ai.provider", havingValue = "openai")
    public ChatModel openAiChatModel() {
        return new OpenAiChatModel(apiKey, model);
    }
}

// LangChain4j的企业级配置示例
@Configuration
public class LangChain4jConfig {
    
    @Bean
    public EmbeddingStore<TextSegment> embeddingStore() {
        // 支持多种向量数据库
        return new InMemoryEmbeddingStore<>();
    }
    
    @Bean
    public EmbeddingModel embeddingModel() {
        return new OpenAiEmbeddingModel(apiKey);
    }
    
    @Bean
    public RetrievalAugmentedGenerator rag() {

            chatLanguageModel(), 
            contentRetriever()
