AI 剖析：LangChain4j 与 Spring AI
智能体（agentic）应用带来了独特的剖析挑战。除了标准的 CPU 使用率之外，性能和成本还取决于提示词、RAG 检索器和工具调用所构成的复杂结构，而这些结构往往隐藏在框架抽象之下。
为了避免厂商锁定，大多数开发者都会使用 LangChain4j 或 Spring AI 这样的框架。JProfiler 的 AI 探针可让您深入了解这些框架。
这段录屏视频逐步演示了如何剖析一个 LangChain4j 客户支持智能体，展示了 AI 探针如何将提示词的构成可视化、隔离出 token 消耗高的异常调用，并将资源成本直接投射到所记录的调用树上。
