1、pom依赖

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><langchain4j.version>0.35.0</langchain4j.version>
</properties><dependencies><dependency><groupId>dev.langchain4j</groupId><artifactId>langchain4j</artifactId><version>${langchain4j.version}</version></dependency><dependency><groupId>dev.langchain4j</groupId><artifactId>langchain4j-open-ai</artifactId><version>${langchain4j.version}</version></dependency><dependency><groupId>org.tinylog</groupId><artifactId>tinylog-impl</artifactId><version>2.6.2</version></dependency><dependency><groupId>org.tinylog</groupId><artifactId>slf4j-tinylog</artifactId><version>2.6.2</version></dependency><dependency><groupId>dev.langchain4j</groupId><artifactId>langchain4j-dashscope</artifactId><version>${langchain4j.version}</version><exclusions><exclusion><artifactId>slf4j-simple</artifactId><groupId>org.slf4j</groupId></exclusion></exclusions></dependency>
</dependencies>

2、代码

import dev.langchain4j.data.message.AiMessage;
import dev.langchain4j.data.message.UserMessage;
import dev.langchain4j.model.chat.ChatLanguageModel;
import dev.langchain4j.model.dashscope.QwenChatModel;
import dev.langchain4j.model.output.Response;public class Qwen {public static void main(String [] args) {ChatLanguageModel model = QwenChatModel.builder().apiKey("sk-3bfe0dfa79b94aa9b2d2da0a9286b9b1").modelName("qwen-plus").build();UserMessage userMessage1 = UserMessage.userMessage("你好，你是谁？");Response<AiMessage> response1 = model.generate(userMessage1);AiMessage aiMessage1 = response1.content();System.out.println(aiMessage1.text());System.out.println("===============================================");UserMessage userMessage2 = UserMessage.userMessage("请再重复⼀次");Response<AiMessage> response2 = model.generate(userMessage1, aiMessage1, userMessage2);System.out.println(response2.content().text());}
}
