然后我使用命令 yo jhipster:import-jdl jhipster-jdl.jh 生成实体，它运行成功，没有错误.但是当我使用命令 ./mvnw 运行我的项目时，我的项目无法运行，这是日志:
And then I use command yo jhipster:import-jdl jhipster-jdl.jh to generator the entities and it run success, nothing error. But when I run my project with command ./mvnw then my project can't run, this is log:

推荐答案
如果你运行 Maven 测试你可以看到:
If you run Maven test you can see this :
Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: member near line 1, column 17 [select distinct member from com.mycompany.myapp.domain.Member member left join fetch member.userStars]
这是因为 Member 是 JPQL 中的保留字(MEMBER OF 表达式).
This is because Member is a reserved word in JPQL (the MEMBER OF expression).
只需更改成员实体的名称即可.
Just change the name of the Member entity and it should work.
