首先创建一个springboot应用

在pom 文件中添加阿里巴巴数据源依赖

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.1.19</version>
            </dependency>

然后，配置druid

创建一个配置类

package com.linyongbin.springboot_druid.config;
    
    import com.alibaba.druid.pool.DruidDataSource;
    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    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 javax.sql.DataSource;
    import java.util.Arrays;
    import java.util.HashMap;
    import java.util.Map;
    
    @Configuration
    public class druidConfig {
        @ConfigurationProperties(prefix = "spring.datasource")
        @Bean
        public DataSource getdruidDataSource(){
            return new DruidDataSource();
        }
        @Bean
        public ServletRegistrationBean statViewServlet(){
            //新建一个Servlet的注册类，加入druid的Servlet，地址是/druid,当我们访问 
            localhost:8080/druid时，就会出现后台管理页面
            ServletRegistrationBean bean=new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
            Map<String,String> initParmer=new HashMap<>();
            //下面是登录druid的管理后台用户名和密码
            initParmer.put("loginUsername","linyongbin");
            initParmer.put("loginPassword","admin");
            initParmer.put("allow","192.168.56.1");//允许范围druid监控的ip,比如我写的是我自己的 
            ip
            bean.setInitParameters(initParmer);
            return bean;
        }
        @Bean
        public FilterRegistrationBean webFilterRegirster(){
            //新建一个过滤器,放行静态资源,还有/druid下的请求
            FilterRegistrationBean bean=new FilterRegistrationBean();
            bean.setFilter(new WebStatFilter());
            Map<String,String> map=new HashMap<>();
            map.put("exclusions","*.js,*.css,/druid/*");
            bean.setInitParameters(map);
            bean.setUrlPatterns(Arrays.asList("/*"));
            return bean;
    
        }
    }

访问localhost:8080/druid
