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:
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>
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
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);
}
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);
}
}
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。
