配置数据源监控
@Configuration
public class DruidConfig {

@ConfigurationProperties(prefix = "spring.datasource")
@Bean
public DataSource druid(){
return new DruidDataSource(http://www.my516.com);
}

//配置监控
//1.配置一个管理后台的servlet
@Bean
public ServletRegistrationBean staViewServlet(){
ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
Map<String,Object> initParams = new HashMap<>();
initParams.put("loginUsername", "admin");//自己编写
initParams.put("loginPassword", "123456");//自己编写
initParams.put("allow", "");
// initParams.put("deny", "");
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,Object> initParams = new HashMap<>();
initParams.put("exclusions", "*.js,*.css,/druid/*");

bean.setInitParameters(initParams);
bean.setUrlPatterns(Arrays.asList("/*"));

return bean;
}
