一、創建項目導入相關依賴
1.1
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
<version>5.1.27</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
二、創建User實體類,UserService,UserController
2.1
在application.properties文件中設置多數據源
spring.datasource.one.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.one.url=jdbc:mysql://127.0.0.1:3306/jdbctemplates?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=GMT
spring.datasource.one.username=root
spring.datasource.one.password=123
spring.datasource.two.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.two.url=jdbc:mysql://127.0.0.1:3306/jdbctemplates2?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=GMT
spring.datasource.two.username=root
spring.datasource.two.password=123
2.2
由於我們配置了多數據源，springboot提供的自動化配置也就失效，需要我們手動配置。
創建DataSourceConfig和jdbctemplateConfig配置類
@Qualifier |
作用告訴他使用哪個DataSource |
@ConfigurationProperties |
加載application.perteries的哪個數據源 |
2.2
創建UserService
3.3
創建Controller
