1.druid依赖

<!-- https://mvnrepository.com/artifact/com.alibaba/druid-spring-boot-starter -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.16</version>
</dependency>

监控页面访问路径：http://localhost:21018/context-path/druid/index.html

2.Druid监控页面设置用户密码

@Bean
	public ServletRegistrationBean statViewServlet() {
		final ServletRegistrationBean<StatViewServlet> servletRegistrationBean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
		// 配置druid参数
		Map<String, String> initParams = new HashMap<>(16);
		// 默认访问用户密码 admin:admin
		initParams.put("loginUsername", "admin");
		initParams.put("loginPassword", "qwer1234!@#$");
		// 允许访问的ip
		initParams.put("allow", "127.0.0.1");
		// 黑名单ip，优先级比allow配置高
		initParams.put("deny", "");
		servletRegistrationBean.setInitParameters(initParams);
		return servletRegistrationBean;
	}

3.Druid去除底部Ad(广告)

@Bean
	public FilterRegistrationBean removeDruidAdFilterRegistrationBean(DruidStatProperties properties) {
		// 获取web监控页面的参数
		DruidStatProperties.StatViewServlet config = properties.getStatViewServlet();
		// 提取common.js的配置路径
		String pattern = config.getUrlPattern() != null ? config.getUrlPattern() : "/druid/*";
		String commonJsPattern = pattern.replaceAll("\\*", "js/common.js");

		final String filePath = "support/http/resources/js/common.js";
		// 创建filter进行过滤
		Filter filter = new Filter() {
			@Override
			public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
				filterChain.doFilter(servletRequest, servletResponse);
				// 重置缓冲区，响应头不会被重置
				servletResponse.resetBuffer();
				// 获取common.js 
				// import com.alibaba.druid.util.Utils;
				String text = Utils.readFromResource(filePath);

				// 正则替换banner, 除去底部的广告信息
				text = text.replaceAll("<a.*?banner\"></a><br/>", "");
				text = text.replaceAll("powered.*?shrek.wang</a>", "");
				servletResponse.getWriter().write(text);
			}

		};

		FilterRegistrationBean registrationBean = new FilterRegistrationBean();
		registrationBean.setFilter(filter);
		registrationBean.addUrlPatterns(commonJsPattern);

		return registrationBean;
	}
