springboot 利用druid配置mysql

1、maven

	<properties>
		<mysql.version>5.1.47</mysql.version>
		<druid.version>1.1.9</druid.version>
		<snakeyaml.version>1.23</snakeyaml.version>
	</properties>

	<!-- MySQL -->
	<dependency>
		<groupId>mysql</groupId>
		<artifactId>mysql-connector-java</artifactId>
		<version>${mysql.version}</version>
	</dependency>
	<!-- druid数据库连接池 -->
	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>druid-spring-boot-starter</artifactId>
		<version>${druid.version}</version>
	</dependency>
	<dependency>
		<groupId>org.yaml</groupId>
		<artifactId>snakeyaml</artifactId>
		<version>${snakeyaml.version}</version>
	</dependency>

2、*.yml所处的项目结构

3、配置内容

server:
  port: 8080
spring:
  application:
    name: TEST(TestApplication启动类)
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      filters: stat
      driver-class-name: com.mysql.jdbc.Driver
      #基本属性
      url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
      username: root
      password: root
      #配置初始化大小/最小/最大
      initial-size: 1
      min-idle: 1
      max-active: 20
      #获取连接等待超时时间
      max-wait: 60000
      #间隔多久进行一次检测，检测需要关闭的空闲连接
      time-between-eviction-runs-millis: 60000
      #一个连接在池中最小生存的时间
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 'x'
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      #打开PSCache，并指定每个连接上PSCache的大小。oracle设为true，mysql设为false。分库分表较多推荐设置为false
      pool-prepared-statements: false
      max-pool-prepared-statement-per-connection-size: 20
