一、hive表：

启动hiveserver2
二、添加mybatis starter和hive依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>hivejdbc</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target></properties><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.6</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.1</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.apache.hive</groupId><artifactId>hive-jdbc</artifactId><version>2.1.1</version><exclusions><exclusion><groupId>org.eclipse.jetty</groupId><artifactId>jetty-runner</artifactId></exclusion></exclusions></dependency><!-- https://mvnrepository.com/artifact/org.apache.hive/hive-exec --><dependency><groupId>org.apache.hive</groupId><artifactId>hive-exec</artifactId><version>3.0.0</version></dependency></dependencies></project>

三、配置文件application.properties中配置数据源：

server.port=9202
spring.datasource.driverClassName=org.apache.hive.jdbc.HiveDriver
spring.datasource.url=jdbc:hive2://xx.xx.xx.xx:10000/default
spring.datasource.username=
spring.datasource.password=

四、定义mapper

package cn.edu.tju.mapper;import cn.edu.tju.domain.UserInfo;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;import java.util.List;
import java.util.Map;@Mapper
public interface UserInfoMapper {@Select("select * from userinfo")List<Map<String,Object>> getUserList();}

五、定义controller,注入mapper并使用

package cn.edu.tju.controller;import cn.edu.tju.domain.UserInfo;
import cn.edu.tju.mapper.UserInfoMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;
import java.util.Map;@RestController
public class UserInfoController {@Autowiredprivate UserInfoMapper userInfoMapper;@RequestMapping("/getUserInfo")public String getUserInfo() {List<Map<String, Object>> userList = userInfoMapper.getUserList();int size = userList.size();//System.out.println(size);for (int i = 0; i < size; i ++ ){Map userInfo = (Map)userList.get(i).get("userinfo");System.out.println(userInfo.get("x"));System.out.println(userInfo.get("y"));}return "ok";}}
