SpringBoot整合druid连接池

1、pom.xml依赖

 <!-- 阿里数据库连接池 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.8</version>
        </dependency>

  

2、application.yml配置文件

# Spring配置
#spring:
#  datasource:
#    driver-class-name: com.mysql.cj.jdbc.Driver
#    url: jdbc:mysql://localhost:3306/feng?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
#    username: root
#    password: 123456



# 数据源配置
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/feng?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
    username: root
    password: 123456
    driverClassName: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      # 初始连接数
      initialSize: 5
      # 最小连接池数量
      minIdle: 10
      # 最大连接池数量
      maxActive: 20
      # 配置获取连接等待超时的时间
      maxWait: 60000
      # 配置连接超时时间
      connectTimeout: 30000
      # 配置网络超时时间
      socketTimeout: 60000
      # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
      timeBetweenEvictionRunsMillis: 60000
      # 配置一个连接在池中最小生存的时间,单位是毫秒
      minEvictableIdleTimeMillis: 300000
      # 配置一个连接在池中最大生存的时间,单位是毫秒
      maxEvictableIdleTimeMillis: 900000
      # 配置检测连接是否有效
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      webStatFilter:
        enabled: true
      statViewServlet:
        enabled: true
        # 设置白名单,不填则允许所有访问
        allow:
        url-pattern: /druid/*
        # 控制台管理用户名和密码
        login-username: feng
        login-password: 123456
      filter:
        stat:
          enabled: true
          # 慢SQL记录
          log-slow-sql: true
          slow-sql-millis: 1000
          merge-sql: true
        wall:
          config:
            multi-statement-allow: true

  

3、DruidDatasrouceConfig配置类

package com.feng.core.config;

import com.alibaba.druid.pool.DruidDataSource;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 *  访问地址:http://localhost:8089/druid/login.html
 */
@Configuration
@Slf4j
public class DruidDatasrouceConfig {

    /**
     * DruidDatasrouceConfig
     * @return DataSource
     */
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DruidDataSource druidDataSource() {
        //
        DruidDataSource druidDataSource = new DruidDataSource();

        log.info("Datasource创建完成 ...");
        log.info(druidDataSource.toString());

        return druidDataSource;
    }
}

  

4、测试:http://localhost:8089/druid/login.html
