Druid监控页面404?报错

springboot集成Druid数据源，没有报错，但是访问不了监控登录页面

application.properties文件如下

##validate  加载hibernate时，验证创建数据库表结构
##create   每次加载hibernate，重新创建数据库表结构，这就是导致数据库表数据丢失的原因。
##create-drop        加载hibernate时创建，退出是删除表结构
##update                 加载hibernate自动更新数据库结构
##validate 启动时验证表的结构，不会创建表
##none  启动时不做任何操作
spring.jpa.hibernate.ddl-auto=validate

##控制台打印sql
spring.jpa.show-sql=true

##数据库配置
##数据库地址
spring.datasource.url=jdbc:mysql://localhost:3306/test
##数据库用户名
spring.datasource.username=xxx
##数据库密码
spring.datasource.password=xxx
##数据库驱动
spring.datasource.driver-class-name=com.mysql.jdbc.Driver


#这里是不同的
#使用druid的话 需要多配置一个属性spring.datasource.type
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource  


# 连接池的配置信息
# 初始化大小，最小，最大
spring.datasource.initialSize=5  
spring.datasource.minIdle=5  
spring.datasource.maxActive=20  
# 配置获取连接等待超时的时间
spring.datasource.maxWait=60000  
# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000  
# 配置一个连接在池中最小生存的时间，单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000  
spring.datasource.validationQuery=SELECT 1 FROM DUAL  
spring.datasource.testWhileIdle=true  
spring.datasource.testOnBorrow=false  
spring.datasource.testOnReturn=false  
# 打开PSCache，并且指定每个连接上PSCache的大小
spring.datasource.poolPreparedStatements=true  
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20  
# 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
spring.datasource.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能；慢SQL记录

继承Druid的servlet和过滤器

package com.store.viewDruid;

import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

import com.alibaba.druid.support.http.WebStatFilter;

@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
initParams={
        @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")//忽略资源
}
)
public class DruidFilter extends WebStatFilter{
	
}

package com.store.viewDruid;

import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;

import com.alibaba.druid.support.http.StatViewServlet;

@WebServlet(urlPatterns="/druid/*",
        initParams={
                @WebInitParam(name="allow",value="localhost"),// IP白名单(没有配置或者为空，则允许所有访问)
                @WebInitParam(name="deny",value=""),// IP黑名单 (deny优先于allow)
                @WebInitParam(name="loginUsername",value="admin"),// 登录druid管理页面用户名
                @WebInitParam(name="loginPassword",value="admin")// 登录druid管理页面密码
        })
public class DruidServlet extends StatViewServlet {
	
}

启动类也加上了servlet的扫描注解

package com.store.viewSource;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

@SpringBootApplication
@ServletComponentScan
public class ViewSourceApplication {

	public static void main(String[] args) {
		SpringApplication.run(ViewSourceApplication.class, args);
	}
}

最后的启动后也是正常的，没有任何关于的异常

For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

这个总是报404

求各位大佬解答一下这是为什么，找了一晚上都没找到哪里错了
