Answer 1

可能会迟到但我遇到了同样的问题并通过检查类DatabaseConfiguration中声明的包扫描更改日志来解决它

// package to scan for migrations 
mongobee.setChangeLogsScanPackage("com.jhipster.web.config.dbmigrations");

这里的示例包是"com.jhipster.web.config.dbmigrations".转到该包并创建一个这样的类:

package com.jhipster.web.config.dbmigrations;
import com.github.mongobee.changeset.ChangeLog;

@ChangeLog
public class DatabaseChangelog {
}

然后警告/错误将消失.
