問題描述
- 現在使用mysql版本5.7+
- 原使用mysql版本5.5
- 原配置文件
driverClassName: com.mysql.jdbc.Driver
url：jdbc:mysql://127.0.0.1:3306/littlebusiness?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8
username：root
password：123
問題1
報第一個錯
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.
根據提示修改url
url：jdbc:mysql://127.0.0.1:3306/littlebusiness?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false
問題二
發現問題還是未解決，那是因爲mysql.connection驅動版本過低，修改pom文件
<mysql.version>5.1.38</mysql.version>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql.version}</version>
</dependency>
// 將版本控制修改爲
<mysql.version>8.0.11</mysql.version>
問題三
- 又拋出該
The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.“異常 - mysql高版本必須配置時區
// 修改url 和driverClassName
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/littlebusiness?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
於是既可成功連接
