## 1.druid依赖 ##

<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][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;
    	}
