springboot配置druid监控

场景:使用druid自带监控功能,监控sql等
1.使用springboot的Spring Initializr创建web项目,确保springboot配置Druid数据源能正常启动并访问数据库
具体可以参考:springboot集成jdbc集成数据源
2.在spring web项目中只要在web.xml中配置一个filter和servlet如下:

   <filter>
       <filter-name>DruidWebStatFilter</filter-name>
       <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
       <init-param>
           <param-name>exclusions</param-name>
           <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value>
       </init-param>
   </filter>
   <filter-mapping>
       <filter-name>DruidWebStatFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>
   <servlet>
       <servlet-name>DruidStatView</servlet-name>
       <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
   </servlet>
   <servlet-mapping>
       <servlet-name>DruidStatView</servlet-name>
       <url-pattern>/druid/*</url-pattern>
   </servlet-mapping>
   
3.在springboot模式下,配置如上配置文件中实现的在配置类中实现即可。
<1>.配置过滤器,即把WebStatFilter注册到FilterRegistrationBean注册器

/**2、配置一个web监控的filter**/
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean beanFilter = new FilterRegistrationBean();
        beanFilter.setFilter(new WebStatFilter());
        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusions","*.js,*.css,/druid/*");
        beanFilter.setInitParameters(initParams);
        beanFilter.setUrlPatterns(Arrays.asList("/*"));
        return  beanFilter;
    }

<2>.配置servlet,即把StatViewServlet注册到ServletRegistrationBean注册器

  /**1、配置一个管理后台的Servlet*/
    @Bean
    public ServletRegistrationBean setStatViewServlet(){
        ServletRegistrationBean beanServlet = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername","test");
        initParams.put("loginPassword","654321");
        initParams.put("allow","");    /**默认就是允许所有访问*/
        beanServlet.setInitParameters(initParams);
        return  beanServlet;
    }

4.访问测试 http:127.0.0.1:8082/druid/index.html 登入页面输入用户名test 口令654321

springboot配置druid监控

5.监控页面显示,发一个请求,查了一条sql,如图监控到

springboot配置druid监控

以上,TKS.
