MyBatis-Plus 已更新到最新版本 3.2.0 使用Wrappers.query().lambda()构建查询语句 报ClassNotFoundException

当前使用版本(必填,否则不予处理)

implementation 'com.baomidou:mybatis-plus-boot-starter:3.3.2'

该问题是如何引起的？(确定最新版也有问题再提!!!)

LambdaQueryWrapper<Template> lambdaQueryWrapper = new LambdaQueryWrapper<>();
lambdaQueryWrapper.eq(Template::getSystemId, "xxx");
lambdaQueryWrapper.eq(Template::getBussinessUnit, "xxx");
lambdaQueryWrapper.eq(Template::getMessageType, "xxx");

重现步骤(如果有就写完整)

解决方案： 去除spring-boot-maven-plugin插件进行打包或升级至3.3.2

此时需要注意 jre 的版本，生产环境刚好用到 openjdk16-openj9 这个版本会提示上面的错误。

建议使用 openjdk
