springboot+mybatis配置clickhouse实现插入查询功能

以下是关于Spring Boot + MyBatis配置ClickHouse实现插入查询功能的完整攻略,包含两个示例说明:

1. 添加ClickHouse依赖

在项目的pom.xml文件中添加ClickHouse的依赖:

<dependency>
    <groupId>ru.yandex.clickhouse</groupId>
    <artifactId>clickhouse-jdbc</artifactId>
    <version>0.3.1</version>
</dependency>

2. 配置ClickHouse数据源

在application.properties(或application.yml)文件中配置ClickHouse的数据源信息:

spring.datasource.url=jdbc:clickhouse://localhost:8123/mydatabase
spring.datasource.username=myusername
spring.datasource.password=mypassword
spring.datasource.driver-class-name=ru.yandex.clickhouse.ClickHouseDriver

3. 创建ClickHouseMapper接口

创建一个继承自MyBatis的Mapper接口,用于定义ClickHouse的SQL操作:

@Mapper
public interface ClickHouseMapper {
    @Insert(\"INSERT INTO mytable (column1, column2) VALUES (#{value1}, #{value2})\")
    void insertData(@Param(\"value1\") String value1, @Param(\"value2\") int value2);

    @Select(\"SELECT * FROM mytable WHERE column1 = #{value}\")
    List<MyData> getData(@Param(\"value\") String value);
}

4. 编写Service层代码

创建一个Service类,注入ClickHouseMapper,并在其中编写业务逻辑代码:

@Service
public class ClickHouseService {
    private final ClickHouseMapper clickHouseMapper;

    public ClickHouseService(ClickHouseMapper clickHouseMapper) {
        this.clickHouseMapper = clickHouseMapper;
    }

    public void insertData(String value1, int value2) {
        clickHouseMapper.insertData(value1, value2);
    }

    public List<MyData> getData(String value) {
        return clickHouseMapper.getData(value);
    }
}

示例说明

以上是关于Spring Boot + MyBatis配置ClickHouse实现插入查询功能的完整攻略。示例中展示了如何配置ClickHouse数据源、创建ClickHouseMapper接口以及编写Service层代码。您可以根据实际需求和情况,适当调整和扩展这些示例。
