问题描述

在进行AI应用开发时，引入了langchain4j-community-dashscope包：

<dependency>
	<groupId>dev.langchain4j</groupId>
    <artifactId>langchain4j-community-dashscope</artifactId>
    <version>1.3.0-beta9</version>
</dependency>

此时，langchain4j-community-dashscope包中dashscope-sdk-java的版本是2.21.1.

当我们将AI应用作为微服务，引入Spring-Cloud-Alibaba:2023.0.1.0：

<dependency>
	<groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
    <version>2023.0.1.0</version>
</dependency>

系统在执行到大模型调用时报错：

Caused by: java.lang.NoSuchMethodError: 'com.alibaba.dashscope.aigc.generation.GenerationParam$GenerationParamBuilder com.alibaba.dashscope.aigc.generation.GenerationParam$GenerationParamBuilder.searchOptions(com.alibaba.dashscope.aigc.generation.SearchOptions)'

问题定位

引入的Spring-Cloud-Alibaba：2023.0.1.0后，发现langchain4j-community-dashscope中dashscope-sdk-java版本变成了2.12.0。

因此，可以确定是因为引入spring-cloud-alibaba-dependencies：2023.0.1.0导致的，原因是该版本开始引入了spring-ai的相关依赖：

同时，我们可以发现在spring-cloud-alibaba:2023.0.1.x版本中均存在特定版本的dashscope-sdk-java：

解决方法

在最新的2023.0.3.x版本中已经没有了spring-ai相关的依赖了，因此我们升级一下spring-cloud-alibaba-dependencies的版本：

<dependency>
	<groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
    <version>2023.0.3.3</version>
</dependency>

升级后，langchain4j-community-dashscope中dashscope-sdk-java版本就变正常了。
