spring boot 开启Druid监控功能

1.配置yml

spring:
  datasource:
#   数据源基本配置
    username: song
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://39.106.222.34:3306/mybatis
    type: com.alibaba.druid.pool.DruidDataSource
#   数据源其他配置
    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,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

2.java 代码 

@Configuration
public class DruidConfiguration {

    @Bean
    public ServletRegistrationBean statViewServle(){
        ServletRegistrationBean servletRegistrationBean=new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //IP白名单
        //servletRegistrationBean.addInitParameter("allow","192.168.1.12,127.0.0.1");
        //IP黑名单
        //servletRegistrationBean.addInitParameter("deny","192.168.4.23");
        //控制台用户
        servletRegistrationBean.addInitParameter("loginUsername","admin");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否能够重置数据
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }
    @Bean
    public FilterRegistrationBean statFilter(){
        FilterRegistrationBean filterRegistrationBean=new FilterRegistrationBean(new WebStatFilter());
        //添加过滤规则
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }
}
