Druid是Java語言中最好的數據庫連接池。Druid能夠提供強大的監控和擴展功能。關於詳細介紹可查看http://www.iteye.com/magazines/90

SpringBoot中集成Druid非常簡單

一：yml中添加配置鏈接

spring:
  #MySQL數據庫
  datasource:
    url: jdbc:mysql://182.254.221.58:3306/test?useSSL=false&&characterEncoding=utf8
    username: root
    password: Zoulu19900206@
    driver-class
 
-name: com.mysql.jdbc.Driver
    #配置監控統計攔截的filters，去掉後監控界面sql將無法統計，wall用於防火墻
    filters: stat,wall,log4j
    #最大活躍數
    maxActive: 20
    #初始化數量
    initialSize: 1
    #最大連接等待超時時間
    maxWait: 60000
    #打開PSCache，並且指定每個連接PSCache的大小
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 
 
20
    #通過connectionProperties屬性打開mergeSql功能；慢sql記錄
    connectionProperties: druid.stat.mergeSql=true;druif.stat.slowSqlMillis=5000
    minldle: 1
    timeBetweenEvictionRunsMillis: 60000
    minEvictableTimeMillis: 300000
    validationQuery: select 1 from dual
    testWhileldle: true
    testOnBorrow: false
    testOnReturn: 
 
false

  #JPA
  jpa:
    properties:
      hibernate:
        hbm2ddl.auto: true
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
    show-sql: true

二：添加DruidConfiguration配置類

@Configuration
public class DruidConfiguration {
    @Bean
    public ServletRegistrationBean statViewServlet(){
        //創建servlet註冊實體
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //設置ip白名單
        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //設置ip黑名單，如果allow與deny共同存在時,deny優先於allow
        servletRegistrationBean.addInitParameter("deny","192.168.0.19");
        //設置控制臺管理用戶
        servletRegistrationBean.addInitParameter("loginUsername","xiaopotian");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否可以重置數據
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean statFilter(){
        //創建過濾器
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //設置過濾器過濾路徑
        filterRegistrationBean.addUrlPatterns("/*");
        //忽略過濾的形式
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }

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

三：運行http://localhost:8080/druid進入登陸界面，用上面配置的用戶名密碼登錄即可

非常的簡單
