SpringBoot 配置Druid监控页面

首先创建druid配置类：用户名、密码需要自行修改。

package org.demo;  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 java.util.Arrays; import java.util.HashMap; import java.util.Map;  /****  * 配置好sruid之后，数据源是从默认的tomcat.pool切换到了druid，  * 可是druid的属性比如initialSize、minIdle还未生效，  * 因为在DataSourceProperties.class下没有对应的匹配项，  * 还需要我们手动配置同时配置监控界面:  *  */ public class DruidConfig {     // 将所有前缀为spring.datasource下的配置项都加载到DataSource中      @ConfigurationProperties(prefix ="spring.datasource")     @Bean     public DruidDataSource druidDataSource() {          return new DruidDataSource();      }      @Bean     public ServletRegistrationBean druidStatViewServlet() {          ServletRegistrationBean<StatViewServlet> registrationBean = new ServletRegistrationBean<>(new StatViewServlet(),  "/druid/*");         registrationBean.addInitParameter("allow", "127.0.0.1");// IP白名单 (没有配置或者为空，则允许所有访问)         registrationBean.addInitParameter("deny", "");// IP黑名单 (存在共同时，deny优先于allow)         registrationBean.addInitParameter("loginUsername", "admin");         registrationBean.addInitParameter("loginPassword", "admin");         registrationBean.addInitParameter("resetEnable", "false");         return registrationBean;      }      @Bean     public FilterRegistrationBean druidWebStatFilter() {         FilterRegistrationBean filterRegistrationBean =new FilterRegistrationBean(new WebStatFilter());         Map initParams =new HashMap<>();         initParams.put("exclusions", "*.js,*.css,/druid/*");         filterRegistrationBean.setInitParameters(initParams);         filterRegistrationBean.setUrlPatterns(Arrays.asList("/*"));         return filterRegistrationBean;     } } 

由于需要验证账户密码，所以需要在application.properties配置原始账户密码：

spring.datasource.druid.stat-view-servlet.login-username=admin spring.datasource.druid.stat-view-servlet.login-password=admin

起动项目：浏览器输入：http://localhost:6000/druid/login.html  
登录账户密码，可以看到后台界面，操作项目业务之后，查看各项日志记录：
