Springboot啟動(dòng)項(xiàng)目

Springboot新手，第一次搭建環(huán)境，啟動(dòng)項(xiàng)目，報(bào)錯(cuò)如下。

看起來是某一個(gè)Class沒有找到。

百度的答案只有一條，在啟動(dòng)類上添加@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})事實(shí)證明無果。

后期懷疑是不是mysql驅(qū)動(dòng)的版本問題，https://mvnrepository.com/ 上搜索替換了N個(gè)版本，報(bào)錯(cuò)相同。

走投無路之際懷疑是不是配置文件寫錯(cuò)了，盯著看了幾分鐘，
driver-class-name: com.mysql.jdbc.driver怎么看怎么奇怪。

試著改成
driver-class-name: com.mysql.jdbc.Driver運(yùn)行，成功！

如果遇到類似問題，在添加注解信息之外，可以考慮是不是配置文件寫錯(cuò)等問題。畢竟這種問題很難百度，網(wǎng)上搜索到的類似報(bào)錯(cuò)也不會(huì)提供正確的寫法。遂記錄。

正確版本如下

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      driver-class-name: com.mysql.jdbc.Driver
      url: jdbc:mysql://localhost:3306/emos?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
      username: root
      password: root
      initial-size: 2
      max-active: 4
      min-idle: 2
      max-wait: 60000
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
