首先确定以后hive的版本
例如：我目前的版本就是
hive-common-1.1.0-cdh5.16.2.jar
SpringBoot工程通过jdbc连贯Hive
留神：引入的Hive-jdbc依赖需与Hive版本保持一致。
顺次对应hive-common-1.1.0引入的Hive-jdbc版本为1.1.0(其中排除log4j依赖是为了解决原工程引入Hive依赖后导致日志不输入问题)
<dependency> <groupId>org.apache.hive</groupId> <artifactId>hive-jdbc</artifactId><version>1.1.0</version>
<exclusions> <exclusion> <groupId>org.eclipse.jetty.aggregate</groupId> <artifactId>*</artifactId> </exclusion> <exclusion> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> </exclusion> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </exclusion> <exclusion> <groupId>org.apache.log4j</groupId> <artifactId>org.apache.hive.org.apache.log4j</artifactId> </exclusion> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> </exclusions> </dependency>关引入Hive-jdbc1.1.0再去尝试连贯同样会产生报错
报错信息如下

<dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-common</artifactId> <version>2.6.5</version> <exclusions> <exclusion> <artifactId>servlet-api</artifactId> <groupId>javax.servlet</groupId> </exclusion> <exclusion> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> </exclusion> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </exclusion> <exclusion> <groupId>org.apache.log4j</groupId> <artifactId>org.apache.hive.org.apache.log4j</artifactId> </exclusion> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> </exclusions> </dependency>再去测试咱们的Demo，胜利了！
Demo代码如下：
public void test2() throws Exception{
// 注册数据库驱动，用的hive的jdbc，驱动名固定写死 Class.forName("org.apache.hive.jdbc.HiveDriver"); // 如果用的是hive2服务，则写jdbc:hive2，前面跟上hive服务器的ip以及端口号，端口号默认是10000 Connection conn = DriverManager.getConnection("jdbc:hive2://1服务器IP:10000/库名", "用户名", "明码"); Statement stat = conn.createStatement(); ResultSet rs = stat.executeQuery("select api_id from idc.ods_duas_data_services_mng where thedate = '20220424' and api_id regexp 'companyInfo'"); while (rs.next()) { String api_id = rs.getString("api_id"); System.out.println(api_id); } stat.close(); conn.close();}完满解决SpringBoot通过jdbc连贯Hive问题！
