向量数据库Milvus-sdk-java整合Spring-Boot, 并整合apache-commons-pool2实现连接池管理

为了在Spring Boot项目中整合Milvus SDK for Java和Apache Commons Pool2来管理Milvus连接，你需要进行以下步骤：

1. 在pom.xml中添加依赖：

<!-- Milvus SDK for Java -->
<dependency>
    <groupId>io.milvus</groupId>
    <artifactId>milvus-sdk-java</artifactId>
    <version>您的Milvus SDK版本</version>
</dependency>
<!-- Apache Commons Pool2 for Resource Pool Management -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>您的Apache Commons Pool2版本</version>
</dependency>

2. 创建Milvus连接工厂类，实现PoolableObjectFactory接口：

import io.milvus.client.MilvusClient;
import org.apache.commons.pool2.PooledObject;
import org.apache.commons.pool2.impl.DefaultPooledObject;
import org.apache.commons.pool2.PooledObjectFactory;
 
public class MilvusClientFactory implements PooledObjectFactory<MilvusClient> {
    @Override
    public MilvusClient create() throws Exception {
        // 创建MilvusClient实例
        String host = "localhost";
        int port = 19530;
        return new MilvusClient(host, port);
    }
 
    @Override
    public PooledObject<MilvusClient> wrap(MilvusClient milvusClient) {
        return new DefaultPooledObject<>(milvusClient);
    }
 
    // 其他方法实现...
}

3. 配置Apache Commons Pool2的GenericObjectPool：

import org.apache.commons.pool2.impl.GenericObjectPool;
import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
 
@Configuration
public class MilvusClientConfig {
    @Bean
    public GenericObjectPool<MilvusClient> milvusClientPool() {
        GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
        poolConfig.setMaxTotal(10); // 设置最大连接数
        poolConfig.setMaxIdle(5); // 设置最大空闲连接数
        poolConfig.setMinIdle(2); // 设置最小空闲连接数
 
        MilvusClientFactory factory = new MilvusClientFactory();
        GenericObjectPool<MilvusClient> pool = new GenericObjectPool<>(factory, poolConfig);
        return pool;
    }
}

4. 使用连接池：

@Service
public class MilvusService {
 
    private final GenericObjectPool<MilvusClient> milvusClientPool;
 
    @Autowired
    public MilvusService(GenericObjectPool<MilvusClient> milvusClientPool) {
        this.milvusClientPool = milvusClientPool;
    }
 
    public void performMilvusOperation() {
        MilvusClient milvusClient = null;
        try {
            // 从连接池中获取MilvusClient实例
            milvusClient = milvusClientPool.borrowObject();
