第4章 创建工程

4.1 新建工程

在IDEA中新建工程，并使用SpringInitializr来创建：

点击下一步，输入项目的GAV坐标及工程构造方式后点击下一步：

点击下一步，选择主版本和模块，这里以Spring2.x版本为例，引入JDBC和对接Redis及Kafka的Starter。

之后点击下一步后确认项目存放位置，点击finish完成。

4.2 引入其他依赖

由于工程需要从多个数据源读取数据，这里引入baomidou组织的动态数据源切换依赖。

同时引入mysql，clickhouse，phoenix，spring-data-elasticsearch的驱动及相关依赖。pom.xml中引入的依赖如下：

<dependencies>

    <!-- springmvc模块 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>

</dependencies>

4.3 添加配置

添加项目中所需要的数据源连接信息及框架配置如下，其中红色部分需要替换为自己的配置。

dest:
logUrl: http://localhost:8080/app
redisDataKey: hotphone
param: logStr
topic: userLog

mybatis:
configuration:
mapUnderscoreToCamelCase: true

spring:
kafka:
bootstrap-servers: hadoop102:9092
elasticsearch:
uris: http://hadoop102:9200
redis:
host: hadoop102
port: 6379
datasource:
dynamic:
primary: mysql
strict: false
datasource:
mysql:
url: jdbc:mysql://hadoop102:3306/gmall_report?serverTimezone=Asia/Shanghai&useSSL=false&useUnicode=true&characterEncoding=UTF-8
username: root
password: “000000”
driver-class-name: com.mysql.cj.jdbc.Driver
ck:
url: jdbc:clickhouse://hadoop102:8123/default
