druid console can not monitor sql problem

springboot + mybatisplus + druid after following the tutorial configured, druid console to monitor sql page no data, filter class name is blank, seemingly not registered to go in, as follows:

@Configuration
public class DruidConfiguration {

    
    @Bean
    public ServletRegistrationBean druidServlet() {
        ServletRegistrationBean<Servlet> bean = new ServletRegistrationBean<>(new StatViewServlet(),"/druid/*");
        Map<String,String> map = new HashMap<>();
        map.put("loginUsername","admin");
        map.put("loginPassword","123456");
        map.put("deny","192.168.47.156");
        bean.setInitParameters(map);
        return bean;

    }

    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean<Filter> bean = new FilterRegistrationBean<>();
        bean.setFilter(new WebStatFilter());
        Map<String,String> map = new HashMap<>();
        map.put("exclusions","*.js,*.css,/druid/*");
        //拦截所有请求
        bean.setUrlPatterns(Arrays.asList("/*"));
        bean.setInitParameters(map);
        return bean;

    }


    @Bean
    public WallFilter wallFilter(){
        WallFilter wallFilter = new WallFilter();
        wallFilter.setConfig(wallConfig());
        return wallFilter;
    }

    @Bean
    public WallConfig wallConfig(){
        WallConfig wallConfig = new WallConfig();
        wallConfig.setMultiStatementAllow(true);
        //允许一次执行多条语句
        wallConfig.setNoneBaseStatementAllow(true);
        // Allow more substantially non statement other statements 
        wallConfig.setStrictSyntaxCheck (to false); 
        // detect whether the strict syntax 
        return wallConfig; 
    } 

    @Bean (name = "the dataSource") 
    public the dataSource the DataSource () { 
        return new new DruidDataSource () ; 
    } 

    // configuration Manager things 
    @Bean (name = "transactionManager") 
    public DataSourceTransactionManager transactionManager () { 
        return new new DataSourceTransactionManager (dataSource ()); 
    } 

} 
this is only a wallfilter can console display, statfilter ineffective 

solution: 
plus jvm startup parameters: 
-Ddruid.filters = = mergeStat -Ddruid.useGlobalDataSourceStat to true, 
my this is the case.
