public class DruidConfiguration {

    @Bean

 //配置Druid的监控
 //1、配置一个管理后台的Servlet
 @Bean
 public ServletRegistrationBean statViewServlet(){
 ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
 Map<String,String> initParams = new HashMap<>();
 initParams.put("loginUsername","admin");
 initParams.put("loginPassword","123456");
 initParams.put("allow","");//默认就是允许所有访问
 initParams.put("deny","192.168.15.21");
 bean.setInitParameters(initParams);
 return bean;
 }

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