记录解决一个小错误:Establishing SSL connection without server's identity verification is not recommended

异常问题

今天使用springboot连接spring原生的jdbc时出现了问题:
Fri Jan 27 21:23:40 CST 2023 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

翻译过来就是:

WARN:不建议在没有服务器身份验证的情况下建立 SSL 连接。根据 MySQL 5.5.45+、5.6.26+ 和 5.7.6+ 要求,如果未设置显式选项,则必须默认建立 SSL 连接。为了符合不使用 SSL 的现有应用程序,验证服务器证书属性设置为“false”。您需要通过设置 useSSL=false 来显式禁用 SSL,或者设置 useSSL=true 并为服务器证书验证提供信任库。

问题解决

检查了我的springboot中的配置文件

这是我原本的配置文件,时区和字符编码的啥也没配:

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/phpdemo
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver

修改如下:

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/phpdemo?characterEncoding=utf8&serverTimezone=Asia/Shanghai&useSSL=false
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver

再次运行,问题成功解决。

jdbc:url格式:jdbc:mysql://localhost:3306/数据库名称?characterEncoding=utf8&serverTimezone=Asia/Shanghai&useSSL=false
