druid-spring-boot-starter：數據庫連接池，集成到springboot

        </dependency>

1.如上pom.xml插入配置

2.在application.properties里配置，也可以在application.yml里配置，只不過寫法不一樣，但也差不多

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.driver-class-name=oracle.jdbc.driver.OracleDriver
#spring.datasource.druid.url=jdbc:oracle:thin:@localhost:1521:orcl
spring.datasource.druid.url=jdbc:oracle:thin:@192.168.1.11:1521:orcl
spring.datasource.druid.username=platform
spring.datasource.druid.password=platform
spring.datasource.druid.initial-size=5
spring.datasource.druid.minIdle=5
spring.datasource.druid.maxActive=20
spring.datasource.druid.maxWait=60000
spring.datasource.druid.timeBetweenEvictionRunsMillis=60000
spring.datasource.druid.minEvictableIdleTimeMillis=300000
spring.datasource.druid.validationQuery=SELECT 1 FROM DUAL
spring.datasource.druid.testWhileIdle=true
spring.datasource.druid.testOnBorrow=false
spring.datasource.druid.testOnReturn=false
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.druid.filters=stat,wall
spring.datasource.druid.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

3.開始還不了解這些屬性的意思后來去挨個查了下，下面是網上資料

上面都是些常用的屬性。

總結：

Druid是Java語言中最好的數據庫連接池。Druid能夠提供強大的監控和擴展功能。DruidDataSource支持的數據庫：
理論上說，支持所有有jdbc驅動的數據庫。最近發現Druid在springboot框架下有更加好用的Druid Spring Boot Starter，可以省去原本寫Druid的一些配置文件或者@Configuration來配置，直接將配置寫在application.yml或者application.properties里，看起來更簡單一些。
