java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed解决办法
·
今天使用spring boot创建一个简单应用,在进行数据库访问时突然抛出了一个异常:
java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:110) ~[mysql-connector-java-8.0.20.jar:8.0.20]
at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:97) ~[mysql-connector-java-8.0.20.jar:8.0.20]
解决方法比较简单在数据库连接URL上添加allowPublicKeyRetrieval=true即可。
以我本地为例,添加前:
url: jdbc:mysql://localhost:3306/xxx?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=UTF-8&useSSL=false
添加后:
url: jdbc:mysql://localhost:3306/xxx?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=UTF-8&useSSL=false&allowPublicKeyRetrieval=true
