springboot 自身提供了幾款數(shù)據(jù)庫連接池.但是對(duì)于阿里數(shù)據(jù)源并沒有提供,下面直接切入正題

配置 application.propertis

# DataSource settings
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.url = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF8
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver
#連接池的配置信息
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置獲取連接等待超時(shí)的時(shí)間
spring.datasource.maxWait=60000
# 配置間隔多久才進(jìn)行一次檢測(cè)，檢測(cè)需要關(guān)閉的空閑連接，單位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一個(gè)連接在池中最小生存的時(shí)間，單位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打開PSCache，并且指定每個(gè)連接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置監(jiān)控統(tǒng)計(jì)攔截的filters，去掉后監(jiān)控界面sql無法統(tǒng)計(jì)，'wall'用于防火墻
spring.datasource.filters=stat,wall,log4j
# 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 

以上就是配置文件的配置..下面請(qǐng)看 java 代碼 DruidDBConfig.java

以上就是整合代碼.下面通過http://127.0.0.1:8088/druid/login.html查看首頁,如圖


這樣就整合完畢了..是不是 很簡(jiǎn)單.
