2、配置文件
如果选择druid链接池要去除druid配置；还要配置一个默认数据源（spring.datasource.dynamic.primary）

#Service Config
server.port=8912
server.tomcat.uri-encoding=UTF-8

#DRUID POOL Congif
spring.datasource.dynamic.druid.initial-size=5
spring.datasource.dynamic.druid.min-idle=5
spring.datasource.dynamic.druid.max-active=20
spring.datasource.dynamic.druid.max-wait=60000
spring.datasource.dynamic.druid.time-between-eviction-runs-millis=60000
spring.datasource.dynamic.druid.min-evictable-idle-time-millis=300000
spring.datasource.dynamic.druid.validation-query=SELECT 1 FROM DUAL 
spring.datasource.dynamic.druid.test-while-idle=true
spring.datasource.dynamic.druid.test-on-borrow=false
spring.datasource.dynamic.druid.test-on-return=false
spring.datasource.dynamic.druid.pool-prepared-statements=true
spring.datasource.dynamic.druid.max-pool-prepared-statement-per-connection-size=20


#去除druid配置
spring.autoconfigure.exclude=com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure



#默认数据源
spring.datasource.dynamic.primary=mysql
#mysql数据源配置

spring.datasource.dynamic.datasource.mysql.username=xxxx
spring.datasource.dynamic.datasource.mysql.password=xxxx

#oracle数据源配置
spring.datasource.dynamic.datasource.oracle.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.dynamic.datasource.oracle.url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST= (ADDRESS=(PROTOCOL=TCP)(HOST=10.48.36.150)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=racdb)))
spring.datasource.dynamic.datasource.oracle.username=xxxx
spring.datasource.dynamic.datasource.oracle.password=xxxx

#mybatis-plus
mybatis-plus.mapper-locations=classpath\:sqlMapperXml/*Mapper.xml

# ELASTICSEARCH (ElasticsearchProperties)

spring.data.elasticsearch.cluster-name=elasticsearch
# Comma-separated list of cluster node addresses.

# Whether to enable Elasticsearch repositories.
spring.data.elasticsearch.repositories.enabled=true

logging.path=logs/

3、数据源切换

@Service
@DS("oracle")
public class QxdmsSurfGuojiaDataHourServiceImpl extends ServiceImpl implements IQxdmsSurfGuojiaDataHourService {

}
