mybatis-generator代码生成报错？

Posted 2023-04-30

springboot集成mybatis做代码生成时报错，具体错误：
[ERROR] Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.2:generate (default-cli) on project trendserver-dal: Communications link failure
[ERROR]
[ERROR] The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

我的mysql版本5.1.73；springboot版本1.5.4；mybatis版本1.3.0；generator插件版本1.3.2

数据库连接/密码反复检查无误，本地连接数据库正常。相同配置连接另一个测试环境mysql5.7.31正常。

大哥，求助。困扰一个晚上了。

仔细检查用户名、密码、连接串是否有错误？ 参考技术A 我也碰到一样的错误，找不到原因，你后来解决没？

mybatis-generator报错：org.mybatis.generator.api.dom.xml.Element

报错信息

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.4.0:generate (default-cli) on project doc-cms: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.4.0:generate failed: A required class was missing while executing org.mybatis.generator:mybatis-generator-maven-plugin:1.4.0:generate: org/mybatis/generator/api/dom/xml/Element

解决办法

mybatis-generator-core 版本(1.4.0)太高, 更换为(1.3.7) 即可
