2.generatorConfig.xml檔案中的資料庫驅動路徑寫錯
<classPathEntry location="/Users/xxx/.m2/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar"/>

3.generatorConfig.xml檔案中的連線資料賬號密碼寫錯
<!--mysql資料庫連線--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="password"/>

4.pom.xml檔案中的沒有新增mybatis外掛
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<!--mybatis用於生成程式碼的配置檔案-->
<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>

5. mysql8 ：客戶端連線caching-sha2-password問題
參考：https://blog.csdn.net/u010026255/article/details/80062153 注意mysql新版本密碼需要複雜些，要包含大寫小寫數字或者特殊符號
ALTER USER 'root'@'localhost' IDENTIFIED BY '這裡寫密碼' PASSWORD EXPIRE NEVER; #修改加密規則 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '這裡寫密碼'; #更新一下使用者的密碼 FLUSH PRIVILEGES; #重新整理許可權
6.Mysql 8授權語句
create user '[email protected]' identified by 'Password'; grant all privileges on *.* to '[email protected]';
