**修改pom**

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.1.0</version>
            </dependency>

**修改配置文件**

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql://localhost:3306/test
    spring.datasource.username=root
    spring.datasource.password=123456

## 方式一 ##

**新建filter**

package com.example.demo.servlet;
    
    import com.alibaba.druid.support.http.WebStatFilter;
    
    import javax.servlet.annotation.WebFilter;
    import javax.servlet.annotation.WebInitParam;
    
    /** * druid过滤器. * * @author :小虎 * @date :2017/12/26 */
    
    @WebFilter(filterName = "druidWebStatFilter", urlPatterns = "/*",
            initParams = {
                    @WebInitParam(name = "exclusions", value = "*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
            }
    )
    public class DruidStatFilter extends WebStatFilter { 
    
    }

**新建servlet**

package com.example.demo.servlet;
    
    import com.alibaba.druid.support.http.StatViewServlet;
    
    import javax.servlet.annotation.WebInitParam;
    import javax.servlet.annotation.WebServlet;
    
    /** * druid数据源状态监控. * * @author :小虎 * @date :2017/12/26 */
    
    
    @WebServlet(urlPatterns = "/druid/*",
            initParams = {
                    @WebInitParam(name = "allow", value = "192.168.1.72,127.0.0.1"),// IP白名单 (没有配置或者为空，则允许所有访问)
                    @WebInitParam(name = "deny", value = "192.168.1.73"),// IP黑名单 (存在共同时，deny优先于allow)
                    @WebInitParam(name = "loginUsername", value = "admin"),// 用户名
                    @WebInitParam(name = "loginPassword", value = "123456"),// 密码
                    @WebInitParam(name = "resetEnable", value = "false")// 禁用HTML页面上的“Reset All”功能
            }
    )
    public class DruidStatViewServlet extends StatViewServlet { 
        private static final long serialVersionUID = 1L;
    
    }

**最后在App.java类上加上注解：@ServletComponentScan是的spring能够扫描到我们自己编写的servlet和filter。**

## 方式二 ##

**新建config**

package com.example.demo.config;
    
    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    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;
    
    /** * druid 配置. * 这样的方式不需要添加注解：@ServletComponentScan * @author :小虎 * @date :2017/12/26 */
    
    
    @Configuration
    public class DruidConfiguration { 
    
        /** * 注册一个StatViewServlet * @return */
        @Bean
        public ServletRegistrationBean DruidStatViewServle2(){
            //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.
            ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid2/*");
    
            //添加初始化参数：initParams
            //白名单：
            servletRegistrationBean.addInitParameter("allow","127.0.0.1");
            //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","192.168.1.73");
            //登录查看信息的账号密码.
            servletRegistrationBean.addInitParameter("loginUsername","admin2");
            servletRegistrationBean.addInitParameter("loginPassword","123456");
            //是否能够重置数据.
            servletRegistrationBean.addInitParameter("resetEnable","false");
            return servletRegistrationBean;
        }
    
        /** * 注册一个：filterRegistrationBean * @return */
        @Bean
        public FilterRegistrationBean druidStatFilter2(){
    
            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,/druid2/*");
            return filterRegistrationBean;
        }
    
    }
