我正在尝试访问一个本地mysql数据库,该数据库有一个名为default的表,其中包含name、id和help列。我正在使用jpa和ebean的play框架。
这是我收到的错误信息。

这是列出所有条目的调用:

private Stream<Language> list(EntityManager em) {
    List<Language> persons = em.createQuery("select p from Language p").getResultList();
    return persons.stream();
}

这就是我正在使用的模型:包模型;

import javax.persistence.*;

@Entity
@Table(name="default")
public class Language {

@Id
@Column(name="`id`")
@GeneratedValue(strategy=GenerationType.AUTO)
public Long id;

@Column(name="`text`")
public String text;

@Column(name="`help`")
public String help;
}

您可以删除@table和@column注解中的所有名称值。
无论如何,hibernate都会选择默认值。
例如,表名肯定不是“default”
