application.properties配置

#数据库连接
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/t1?serverTimezone=Asia/Shanghai
spring.datasource.username=sec
spring.datasource.password=sec123

##启用StatFilter
spring.datasource.druid.web-stat-filter.enabled=true

#启用内置的监控页面
spring.datasource.druid.stat-view-servlet.enabled=true

修复方法

禁用durid

application.properties配置

spring.datasource.druid.stat-view-servlet.enabled=false
spring.datasource.druid.web-stat-filter.enabled=false

设置鉴权

#设置登录用户名
spring.datasource.druid.stat-view-servlet.login-username=admin
#设置登录密码
spring.datasource.druid.stat-view-servlet.login-password=123

修改路径

##内置监控页面的地址
spring.datasource.druid.stat-view-servlet.url-pattern=/druid11111111111111111111111111111/*
