spring boot 中配置clcikhouse，mybatis-plus方式

一、和mysql配置在一起的情况下（使用mybatis-plus）

1、安装依赖

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>dynamic-datasource-spring-boot3-starter</artifactId>
            <version>4.3.1</version>
        </dependency>
<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.23</version>
        </dependency>

        <dependency>
            <groupId>com.clickhouse</groupId>
            <artifactId>clickhouse-jdbc</artifactId>
            <version>0.6.5</version>
        </dependency>

        <dependency>
            <groupId>org.apache.httpcomponents.client5</groupId>
            <artifactId>httpclient5</artifactId>
            <version>5.3.1</version>
        </dependency>

        <dependency>
            <groupId>org.lz4</groupId>
            <artifactId>lz4-java</artifactId>
            <version>1.8.0</version>
        </dependency>

2、配置文件

spring:

  datasource:
    dynamic:
      #默认数据源
      primary: master
      datasource:
        master:
          username: xxxxx
          password: xxxxx
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://localhost:3306/xxxxxx?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true&allowPublicKeyRetrieval=true&allowMultiQueries=true
          hikari:
            max-lifetime: 70000
        clickhouse:
          driverClassName: com.clickhouse.jdbc.ClickHouseDriver
          url: jdbc:clickhouse://localhost:8123/xxxxxxx?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC&allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8
          hikari:
            connection-timeout: 10000
            connection-test-query: select 1
          druid:
            validation-query: SELECT 1

其中matster是mysql的，clickhouse是clickhouse库
3、其余用法和mybatis一样，注在查询的时候，方法上需要加上@DS(“clickhouse”)，则转到clickhouse查询mapper了
