springBoot整合druid数据源
一，添加依赖pom
二。添加配置文件，由于配置项多，为方便阅读，配置为properties文件
server.port=8090
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
#基本配置
spring.datasource.url=jdbc:mysql://192.168.25.130:3306/chong?useUnicode=true&characterEncoding=utf8&useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driverClassName=com.mysql.jdbc.Driver
#初始化时建立的连接数
spring.datasource.initialSize=50
#最小连接数
spring.datasource.minIdle=5
#最大连接数
spring.datasource.maxActive=500
#获取连接最大等待时间，单位：毫秒
spring.datasource.maxWait=60000
#间隔多久进行一次检测，检测需要关闭的空闲连接
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=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
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.filters=stat,wall,slf4j
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=2000
spring.datasource.useGlobalDataSourceStat=true
spring.datasource.druid.filter.stat.logSlowSql=true
spring.datasource.druid.filter.stat.mergeSql=true
spring.datasource.druid.filter.stat.slowSqlMillis=2000
#mybati配置
#mybatis.config-location=classpath:/mybatis-config.xml
mybatis.mapperLocations: classpath:mapper/**/*.xml
logging.config: classpath:log4j2/log4j2.xml
yml文件：
server:
context-path: /web
spring:
datasource:
druid:
# 数据库访问配置, 使用druid数据源
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: oracle.jdbc.driver.OracleDriver
url: jdbc:oracle:thin:@localhost:1521:ORCL
username: test
password: 123456
# 连接池配置
initial-size: 5
min-idle: 5
max-active: 20
# 连接等待超时时间
max-wait: 30000
# 配置检测可以关闭的空闲连接间隔时间
time-between-eviction-runs-millis: 60000
# 配置连接在池中的最小生存时间
min-evictable-idle-time-millis: 300000
validation-query: select '1' from dual
test-while-idle: true
test-on-borrow: false
test-on-return: false
# 打开PSCache，并且指定每个连接上PSCache的大小
pool-prepared-statements: true
max-open-prepared-statements: 20
max-pool-prepared-statement-per-connection-size: 20
# 配置监控统计拦截的filters, 去掉后监控界面sql无法统计, 'wall'用于防火墙
filters: stat,wall
# Spring监控AOP切入点，如x.y.z.service.*,配置多个英文逗号分隔
aop-patterns: com.springboot.servie.*
# WebStatFilter配置
web-stat-filter:
enabled: true
# 添加过滤规则
url-pattern: /*
# 忽略过滤的格式
exclusions: '*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*'
# StatViewServlet配置
stat-view-servlet:
enabled: true
# 访问路径为/druid时，跳转到StatViewServlet
url-pattern: /druid/*
# 是否能够重置数据
reset-enable: false
# 需要账号密码才能访问控制台
login-username: druid
login-password: druid123
# IP白名单
# allow: 127.0.0.1
# IP黑名单（共同存在时，deny优先于allow）
# deny: 192.168.1.218
# 配置StatFilter
filter:
stat:
log-slow-sql: true
三添加，数据源配置，配置监控台，用户密码项等

四，测试数据源
package com.liu.datasource;
import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootSqlApplicationTests {
@Autowired
DataSource dataSource;
@Test
public void contextLoads() throws SQLException {
System.out.println(dataSource.getClass());
Connection connection = dataSource.getConnection();
System.out.println(connection);
connection.close();
}
}
五，执行sql之后，此处不再举例执行sql
访问所配置监控地址 路径 /druid/
