SpringBoot接入百炼大模型

LangChain4j是专为Java开发者设计的大语言模型（LLM）集成框架，支持多种AI模型和向量数据库，简化了Java应用程序与大模型的交互过程。

集成案例实现详细过程

1、开发准备工作
1.1 环境配置要求
JDK 17
SpringBoot 3.4.2
LongChain4j 1.1.0-beta7

配置SpringBoot项目的pom.xml

各种依赖对应的版本信息

<properties>
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<spring-boot.version>3.4.2</spring-boot.version>
<langchain4j-bom.version>1.1.0</langchain4j-bom.version>
<langchain4j.version>1.1.0-beta7</langchain4j.version>
</properties>

增加阿里云百炼平台接入依赖配置

<!– 接入阿里云百炼平台 –>
<dependency>
<groupId>dev.langchain4j</groupId>
<artifactId>langchain4j-community-dashscope-spring-boot-starter</artifactId>
</dependency>

完整配置pom.xml如下

<?xml version=”1.0″ encoding=”UTF-8″?>
<project xmlns=”http://maven.apache.org/POM/4.0.0″

配置application.yml

准备SpringBoot工程的配置文件

server:
port: 8080
#集成langchain4j
langchain4j:
# 阿里百炼平台
community:
dashscope:
chat-model:
api-key: {DASH_SCOPE_API_KEY} #填写开发准备工作阶段登录阿里云百炼申请的API-Key
model-name: qwen3-max
#日志配置
logging:
level:
root: INFO
org.springframework: WARN
file:
name: logs/ai-system.log
pattern:
console: “%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} – %msg%n”

执行验证（测试）

创建验证（测试）代码逻辑

@SpringBootTest(classes = Main.class)
@Slf4j
public class TestDashScopeQwen {

@Autowired
private QwenChatModel qwenChatModel;

@Test
public void testDashScopeQwen(){
String answer = qwenChatModel.chat(“你是谁”);
log.info(“Qwen回答: {}”, answer);
}

}
