java - Hibernate 无效的列名

Question

我正在尝试做一个简单的选择，但出现了这个错误:

这是我的实体。如您所见，它只有一列(这是一个简单的 View )。

@javax.persistence.Table(name = "WIN_ARVORE_EFD_COMPETENCIA", schema = "dbo", catalog = "SPED_WIN")
@Entity
public class VisaoArvoreEfdCompetencia {
    @Id
    private String mesAno;

    @javax.persistence.Column(name = "MES_ANO", nullable = true, insertable = true, updatable = true, length = 7, precision = 0)
    public String getMesAno() {
        return mesAno;
    }

    public void setMesAno(String mesAno) {
        this.mesAno = mesAno;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        VisaoArvoreEfdCompetencia that = (VisaoArvoreEfdCompetencia) o;
        if (mesAno != null ? !mesAno.equals(that.mesAno) : that.mesAno != null) return false;
        return true;
    }

    @Override
    public int hashCode() {
        return mesAno != null ? mesAno.hashCode() : 0;
    }
}

这是这个实体的观点:

SELECT CAST(MONTH(DATAFISCAL) AS VARCHAR(2)) + '_' + CAST(YEAR(DATAFISCAL) AS VARCHAR(4)) AS MES_ANO
FROM dbo.MESFISCAL
WHERE (Status = N'AB')

我的实体映射或 View 有问题吗？

来自 http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html_single/ :

Mixing annotations in both fields and methods should be avoided. Hibernate will guess the access type from the position of @Id or @EmbeddedId.

如果将 @Id 注释放在字段上，则需要将其他 JPA 注释(@Column 等)放在字段上(而不是 getter)。您不能在 getter/字段上混合注释。

所以在这里你可以写:

@Id
@Column(name="MES_ANO", length = 7)
private String mesAno;

请注意，由于该列已经是一个@Id，您的可空/可插入/可更新声明可能没有意义。
