使用GORM 6.1.2查询mongo集合时出现java.lang.reflect.InvocationTargetException

查询域对象列表时，我得到java.lang.reflect.InvocationTargetException:。下面是重现该错误的示例。

UserPaper.groovy： 

class UserPaper {

    ObjectId id
    long userId
    Paper paper

    static embedded = ['paper']
    static constraints = {}
}

UserPaperService.groovy 

List<UserPaper> getAllPapers(User user){

    FindIterable iterable = UserPaper.find(eq('userId', user.id))

    List<UserPaper> papers = iterable.limit(10).collect { UserPaper paper ->
        paper
    }

    return  papers
}

UserPaperController.groovy 

def list(){
    User currentUser = (User) authenticatedUser
    List<UserPaper> papers = userPaperService.getAllPapers(currentUser)
    render papers as JSON
}

使用任何基本的GORM方法，例如find，list，findByUserId引发以下错误：

2018-08-15 23:00:19.013 ERROR --- [nio-8080-exec-7] o.g.web.errors.GrailsExceptionResolver   : InstantiationException occurred when processing request: [GET] /user/paper/list

使用：

  • Grails版本3.3.6
  • Gorm版本6.1.10.BUILD-SNAPSHOT
  • mongodb版本3.6.6

由于我仅将mongodb用作持久性数据存储，因此我从build.gradle中删除了所有休眠依赖关系。
