一、快速开始

1、添加依赖

xml 复制代码

<dependency>
    <groupId>ru.yandex.clickhouse</groupId>
    <artifactId>clickhouse-jdbc</artifactId>
    <version>0.3.1-patch</version>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.6</version>
</dependency>

2、添加配置类

yaml 复制代码

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    click:
      driverClassName: ru.yandex.clickhouse.ClickHouseDriver
      url: jdbc:clickhouse://127.0.0.1:8123/dbname
      username: username
      password: 123456
      initialSize: 10
      maxActive: 100
      minIdle: 10
      maxWait: 6000

3、添加配置类

java 复制代码

@Data
@Component
@ConfigurationProperties(prefix = "spring.datasource.click")
public class JdbcParamConfig {
    private String driverClassName ;
    private String url ;
    private Integer initialSize ;
    private Integer maxActive ;
    private Integer minIdle ;
    private Integer maxWait ;
    private String username;
    private String password;
}

@Configuration
public class DruidConfig {
 
    @Resource
    private JdbcParamConfig jdbcParamConfig ;
 
    @Bean
    public DataSource dataSource() {
        DruidDataSource datasource = new DruidDataSource();
        datasource.setUrl(jdbcParamConfig.getUrl());
        datasource.setDriverClassName(jdbcParamConfig.getDriverClassName());
        datasource.setInitialSize(jdbcParamConfig.getInitialSize());
        datasource.setMinIdle(jdbcParamConfig.getMinIdle());
        datasource.setMaxActive(jdbcParamConfig.getMaxActive());
        datasource.setMaxWait(jdbcParamConfig.getMaxWait());
        datasource.setUsername(jdbcParamConfig.getUsername());
        datasource.setPassword(jdbcParamConfig.getPassword());
        return datasource;
    }
}

实体类和业务实现

java 复制代码

@Data
public class UserInfo implements Serializable {
    private static final long serialVersionUID = 1L;
    private int id;
    private String userName;
    private String passWord;
    private String phone;
    private String email;
    private String createDay;
}

@Repository
public interface UserInfoMapper extends BaseMapper<UserInfo> {
    // 写入数据
    void saveData (UserInfo userInfo) ;
    // ID 查询
    UserInfo selectById (@Param("id") Integer id) ;
    // 查询全部
    List<UserInfo> selectList () ;
}
