springboot多数据源配置示例

好的，以下是一个简单的Spring Boot多数据源配置示例：

1.首先需要在pom.xml文件中添加以下依赖：

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
   <groupId>com.zaxxer</groupId>
   <artifactId>HikariCP</artifactId>
   <version>3.3.1</version>
</dependency>

2.在application.properties文件中配置数据源及相关属性：

# 主数据源
spring.datasource.primary.url=jdbc:mysql://localhost:3306/db1?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
spring.datasource.primary.username=root
spring.datasource.primary.password=password
spring.datasource.primary.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.primary.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.primary.hikari.connectionTimeout=20000
spring.datasource.primary.hikari.maximumPoolSize=30
spring.datasource.primary.hikari.minimumIdle=10

# 第二个数据源
spring.datasource.secondary.url=jdbc:mysql://localhost:3306/db2?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
spring.datasource.secondary.username=root
spring.datasource.secondary.password=password
spring.datasource.secondary.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.secondary.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.secondary.hikari.connectionTimeout=20000
spring.datasource.secondary.hikari.maximumPoolSize=30
spring.datasource.secondary.hikari.minimumIdle=10

3.在代码中配置多数据源：

@Configuration
@EnableTransactionManagement
public class DataSourceConfig {
   @Bean(name = "primaryDataSource")
   @Qualifier("primaryDataSource")
   @ConfigurationProperties(prefix="spring.datasource.primary")
   public DataSource primaryDataSource() {
       return DataSourceBuilder.create().build();
   }

   @Bean(name = "secondaryDataSource")
   @Qualifier("secondaryDataSource")
   @ConfigurationProperties(prefix="spring.datasource.secondary")
   public DataSource secondaryDataSource() {
       return DataSourceBuilder.create().build();
   }
}

4.在需要使用多数据源的Service类上添加@Qualifier注解，指定具体使用哪个数据源：

@Service
public class UserServiceImpl implements UserService {
   @Autowired
   @Qualifier("primaryDataSource")
   private DataSource primaryDataSource;
   
   @Autowired
   @Qualifier("secondaryDataSource")
   private DataSource secondaryDataSource;   
}

以上就是一个简单的Spring Boot多数据源配置示例，希望能够帮助您。
