Springboot里集成Mybatis-plus、ClickHouse
Spring Boot 整合 MyBatis-Plus 和 ClickHouse 的方式主要是配置数据源和定义相应的 Mapper。以下是一个简单的示例:
- 在
pom.xml
中添加依赖:
<!-- MyBatis-Plus -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>最新版本</version>
</dependency>
<!-- ClickHouse -->
<dependency>
<groupId>com.clickhouse</groupId>
<artifactId>clickhouse-jdbc</artifactId>
<version>最新版本</version>
</dependency>
- 配置
application.properties
或application.yml
文件:
# MyBatis-Plus 配置
spring.datasource.url=jdbc:mysql://localhost:3306/yourdb
spring.datasource.username=yourusername
spring.datasource.password=yourpassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
# ClickHouse 配置
clickhouse.db.url=jdbc:clickhouse://localhost:8123
clickhouse.db.user=default
clickhouse.db.password=
- 创建 ClickHouse 的配置类:
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.clickhouse.jdbc.ClickHouseDataSource;
@Configuration
public class ClickHouseConfig {
@Value("${clickhouse.db.url}")
private String clickHouseUrl;
@Value("${clickhouse.db.user}")
private String clickHouseUser;
@Value("${clickhouse.db.password}")
private String clickHousePassword;
@Bean(name = "clickHouseDataSource")
public ClickHouseDataSource clickHouseDataSource() {
ClickHouseDataSource dataSource = new ClickHouseDataSource();
dataSource.setUrl(clickHouseUrl);
dataSource.setUser(clickHouseUser);
dataSource.setPassword(clickHousePassword);
return dataSource;
}
}
- 创建 MyBatis-Plus 的 Mapper 接口和对应的 XML 文件:
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
@Mapper
@Repository
public interface YourEntityMapper extends BaseMapper<YourEntity> {
// 自定义查询方法
}
- 创建实体类和对应的服务层:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class YourService {
@Autowired
private YourEntityMapper yourEntityMapper;
// 使用 MyBatis-Plus 提供的方法或自定义方法
}
- 在
application.java
中启用 MyBatis-Plus 和 ClickHouse 配置:
