在 application.yml 中配置 StatFilter 相关

spring:
  aop:
    proxy-target-class: true
  datasource:
    url: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=bkimDB)))
    username: test

    druid:
      initial-size: 1
      min-idle: 1
      max-active: 3
      max-wait: 60000
      keep-alive: true
      time-between-eviction-runs-millis: 60000
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 'x' FROM DUAL
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      pool-prepared-statements: true
      max-pool-prepared-statement-per-connection-size: 20
      filter:
        wall:
          enabled: true
        stat:
          enabled: true
        config:
          enabled: true
      stat-view-servlet:
        enabled: true
      connection-properties: config.decrypt=true;config.decrypt.key=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAJqw3NwlMJmXvcUbhlOn7VttbKPegs99ToSlKhlvDf4YD04OaD86/csdIVHgKcaCkYWfY3XIh/vJtUOf/QEwG+0CAwEAAQ==
      stat-view-servlet:
        enabled: true
        url-pattern: /druid/*
        # 1.1.13版本及以上，还需要配置allow、deny
        allow:
        deny:
  jpa:
    database: oracle
    properties:
      hibernate:
        dialect: org.hibernate.dialect.Oracle10gDialect

关键配置是

spring:
  datasource:
    druid:
      filter:
        stat:
          enabled: true
      stat-view-servlet:
        enabled: true
        url-pattern: /druid/*
        # 1.1.13版本及以上，还需要配置allow、deny
        allow:
        deny:
