springboot配置完druid，spring监控没有数据？

Question

配置完之后，sql监控有数据，spring监控没有有数据，啥情况？

@Configuration
public class DruidConfig {
    /**
     * 配置Druid监控
     * 后台管理Servlet
     * @return
     */
    @Bean
    public ServletRegistrationBean statViewServlet(){
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","admin");
        //默认就是允许所有访问
        initParams.put("allow","");
        //黑名单的IP
        initParams.put("deny","192.168.15.21");
        bean.setInitParameters(initParams);
        return bean;
    }
    /**
     * 配置web监控的filter
     * @return
     */
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());
        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusions","/static/*,*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return  bean;
    }
}

可以了，原来还需要配置一个切面

@Configuration
public class SpringDaoMethodAspect {

    @Bean
    public DruidStatInterceptor druidStatInterceptor() {
        DruidStatInterceptor dsInterceptor = new DruidStatInterceptor();
        return dsInterceptor;
    }

    @Bean
    @Scope("prototype")
    public JdkRegexpMethodPointcut druidStatPointcut() {
        JdkRegexpMethodPointcut pointcut = new JdkRegexpMethodPointcut();
        pointcut.setPattern("com.yadu.example.demo.mapper.*");
        return pointcut;
    }

    @Bean
    public DefaultPointcutAdvisor druidStatAdvisor(DruidStatInterceptor druidStatInterceptor, JdkRegexpMethodPointcut druidStatPointcut) {
        DefaultPointcutAdvisor defaultPointAdvisor = new DefaultPointcutAdvisor();
        defaultPointAdvisor.setPointcut(druidStatPointcut);
        defaultPointAdvisor.setAdvice(druidStatInterceptor);
        return defaultPointAdvisor;
    }
}
