一、無連接池
1、單一配置
server.port=7654
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mybatisproject?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
2、或者多環境配置spring.profiles.active=test 其中test代表的就是application-test.properties文件配置，同理將test換成dev或者prod改變配置啓動環境，文件目錄圖
application-test.properties
server.port=7654
#默認激活的profiles
spring.profiles.active=test
application-test.properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mybatisproject?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
二、有鏈接池
添加包
pom.xml中添加
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
1、單一環境配置
server.port=7654

spring.datasource.druid.url=jdbc:mysql://localhost:3306/mybatisproject?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
spring.datasource.druid.username=root
spring.datasource.druid.password=123456
# 初始化大小，最小，最大
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-active=20

spring.datasource.druid.max-wait=60000
# 配置間隔多久才進行一次檢測，檢測需要關閉的空閒連接，單位是毫秒
spring.datasource.druid.time-between-eviction-runs-millis=60000

spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false

# 配置監控統計攔截的filters，去掉後監控界面sql無法統計，'wall'用於防火牆，#別名方式，擴展插件，監控統計用的filter:stat，日誌用的filter:log4j，防禦sql注入的filter:wall
spring.datasource.druid.filters=stat,slf4j
2、或者多環境配置spring.profiles.active=dev 其中dev代表的就是application-dev.properties文件配置，同理將dev換成test或者prod改變配置啓動環境，文件目錄圖
application.properties

spring.profiles.active=dev
application-dev.properties
