springboot +mybatis-plus(让人无语的错)

Access denied for user ‘‘@‘localhost‘ (using password: NO)

 

 

 

找了好多资料才发现坑（坑死我了！）
我的数据库配置

spring.datasource.data-username=root
spring.datasource.data-password=root

spring.datasource.url=jdbc:mysql://localhost:3306/mybatis-plus?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=CST
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

 

 

username与password的前面都加了 data-，这是根据自动补全写的，这样写会就报错：Access denied for user ''@'localhost' (using password: NO)

正确配置如下、

#数据库链接
spring.datasource.username=root
spring.datasource.password=root

spring.datasource.url=jdbc:mysql://localhost:3306/mybatis-plus?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=CST
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

 

 

 

 

完美解决！！
