springboot Hive數據連接池

pom.xml依賴文件,項目負載的可能需要解決依賴衝突,idea可以安裝dependency analyzer

        <!-- 數據連接池-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.12</version>
        </dependency>
        <!-- hive jdbc連接-->
        <dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-jdbc</artifactId>
            <version>1.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-service</artifactId>
            <version>1.1.0</version>
        </dependency>

配置文件設置參數

hive:
  url: jdbc:hive2://10.1.24.38:10000/ods #hiveserver2的url
  #url: jdbc:hive2://192.168.1.10:10000/ods #hiveserver2的url
  driver-class-name: org.apache.hive.jdbc.HiveDriver
  type: com.alibaba.druid.pool.DruidDataSource
  user: root #用戶名
  password: root #密碼
  #password: 123456 #密碼
  initialSize: 1
  minIdle: 3
  maxActive: 20
  maxWait: 6000
  timeBetweenEvictionRunsMillis: 60000
  minEvictableIdleTimeMillis: 30000
  validationQuery: select 1
  testWhileIdle: true
  testOnBorrow: false
  testOnReturn: false
  poolPreparedStatements: true
  maxPoolPreparedStatementPerConnectionSize: 20
  connectionErrorRetryAttempts: 0
  breakAfterAcquireFailure: true

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;

import javax.sql.DataSource;

@Configuration
@ConfigurationProperties(prefix = "hive")
@Data
public class HiveDruidConfig {

    private String url;

    private String password;

        return datasource;
    }

}

然後

    @Autowired
    HiveDruidConfig hiveDruidConfig;

    //方法中
    Connection conn=hiveDruidConfig.dataSource().getConnection();

靜態方法中使用

    private static DataSource hiveDataSource;

    @PostConstruct
    public void init() {
        hiveDataSource = hiveDruidConfig.dataSource();
    }

    @Autowired
    HiveDruidConfig hiveDruidConfig;

    //方法中
    Connection conn=hiveDataSource .getConnection();
