博主报的是:
org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
解决:连接不上mysql,一般就是mysql或连接信息有问题,排除mysql,那就是连接信息 有问题了,修改 db.url.0 ,怎么改?
application.properties :
参与上面给的:
比如博主:
spring.datasource.platform=mysql db.num=1 db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC db.user=root db.password=3333
成功!
