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;
    }
}
