### 使用必看：[https://github.com/alibaba/druid/wiki/%E5%B8%B8%E8%A7%81%E9%97%AE%E9%A2%98][https_github.com_alibaba_druid_wiki_E5_B8_B8_E8_A7_81_E9_97_AE_E9_A2_98] ###

### 1、pom文件中一定要配置druid ###

<dependency>
         <groupId>com.alibaba</groupId>
         <artifactId>druid-spring-boot-starter</artifactId>
         <version>1.1.9</version>
    </dependency>

### 2、编写druid filter配置类 ###

package com.mysql.monitor;
    
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    
    @Configuration
    public class DruidMonitorConfig {
        /**
         * 注册ServletRegistrationBean
         * @return
         */
        @Bean
        public ServletRegistrationBean registrationBean() {
            ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
            //白名单
            servletRegistrationBean.addInitParameter("allow", "");//多个ip逗号隔开
            //IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.
            //servletRegistrationBean.addInitParameter("deny", "");
            //登录查看信息的账号密码.
            servletRegistrationBean.addInitParameter("loginUsername", "admin");
            servletRegistrationBean.addInitParameter("loginPassword", "admin");
            //是否能够重置数据.
            servletRegistrationBean.addInitParameter("resetEnable", "true");
            return servletRegistrationBean;
        }
     
     
        /**
         * 注册FilterRegistrationBean
         * @return
         */
        @Bean
        public FilterRegistrationBean druidStatFilter() {
            FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
            //添加过滤规则.
            filterRegistrationBean.addUrlPatterns("/*");
            //添加不需要忽略的格式信息.
            filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
            return filterRegistrationBean;
        }
    }

### 3、修改.properties配置文件 ###

########druid监控###################### 
    # 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,log4j2:日志
    spring.datasource.filters=stat,wall,log4j2
    # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
    spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
    ##日志配置
    # 配置日志输出
    spring.datasource.druid.filter.slf4j.enabled=true
    spring.datasource.druid.filter.slf4j.statement-create-after-log-enabled=false
    spring.datasource.druid.filter.slf4j.statement-close-after-log-enabled=false
    spring.datasource.druid.filter.slf4j.result-set-open-after-log-enabled=false
    spring.datasource.druid.filter.slf4j.result-set-close-after-log-enabled=false

### 4、启动项目，访问  [http://localhost:8080/druid/sql.html][http_localhost_8080_druid_sql.html] ###
