springboot系列(8) --整合添加druid連接池監控

1.功能描述

別的不多說，直接上home圖

官方文檔上面已經有很多的說明了

2.上代碼

DruidConfig 配置類

/**
 * @Classname DruidConfig
 * @Description DruidConfig 配置類
 * @Date 2020/6/12 10:33
 * @Created by corey
 */
@Configuration
public class DruidConfig {

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

    //配置Druid的監控
    //1、配置一個管理後臺的Servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","123456");
        initParams.put("allow","");//默認就是允許所有訪問
        initParams.put("corey","192.168.15.21");
        bean.setInitParameters(initParams);
        return bean;
    }

    //配置Druid的監控
    //1、配置一個管理後臺的Servlet
    @Bean
    public ServletRegistrationBean statViewServlets(){
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","123456");
        initParams.put("allow","");//默認就是允許所有訪問
        initParams.put("deny","192.168.15.21");
        bean.setInitParameters(initParams);
        return bean;
    }

}

數據源配置

#配置數據源
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/tb?useUnicode=true&characterEncoding=utf8&usessl=true&useSSL=false
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    #   配置監控統計攔截的filters，去掉後監控界面sql無法統計，'wall'用於防火牆
    filters: stat,wall
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
