Question

我正在使用注释使用hibernate 4.3，但没有任何映射问题。我迁移到了hibernate 5.1，并且遇到了映射问题。

我检查我的DAO，并且查询使用的名称与我的实体类的名称相同，这是每个人都建议的解决方案。

这是我的实体类

 @Entity
@Table(name = "__maintenance", uniqueConstraints = @UniqueConstraint(columnNames = "name"))
public class __Maintenance implements java.io.Serializable {

    private static final long serialVersionUID = 7217691607923908432L;

    private int idMaintenance;
    private int version;
    private String storyNumber;
    private String name;
    private Date startDate;
    private Date endDate;
    private String comments;

    public __Maintenance() {
    this.version = 1;
    }

    @Deprecated
    public __Maintenance(String storyNumber, String name) {
        this.storyNumber = storyNumber;
        this.name = name;
    }

    @Deprecated
    public __Maintenance(String storyNumber, String name, Date startDate, Date endDate, String comments) {
        this.storyNumber = storyNumber;
        this.name = name;
        this.startDate = startDate;
        this.endDate = endDate;
        this.comments = comments;
    }

    @Id
    @GeneratedValue(strategy = IDENTITY)

    @Column(name = "idMaintenance", unique = true, nullable = false)
    public int getIdMaintenance() {
        return this.idMaintenance;
    }

    public void setIdMaintenance(int idMaintenance) {
        this.idMaintenance = idMaintenance;
    }

    @Column(name = "version", nullable = false)
    public int getVersion() {
        return this.version;
    }

    public void setVersion(int version) {
        this.version = version;
    }

    @Column(name = "story_number", nullable = false, length = 50)
    public String getStoryNumber() {
        return this.storyNumber;
    }

    public void setStoryNumber(String storyNumber) {
        this.storyNumber = storyNumber;
    }

    @Column(name = "name", unique = true, nullable = false, length = 50)
    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "start_datetime", length = 19)
    public Date getStartDate() {
        return this.startDate;
    }

    public void setStartDate(Date startDate) {
        this.startDate = startDate;
    }

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "end_datetime", length = 19)
    public Date getEndDate() {
        return this.endDate;
    }

    public void setEndDate(Date endDate) {
        this.endDate = endDate;
    }

    @Column(name = "comments", length = 65535)
    public String getComments() {
        return this.comments;
    }

    public void setComments(String comments) {
        this.comments = comments;
    }

这是我的查询

        String query = "";
        query += "select m from __Maintenance m";
        query += "  where m.name = :name ";
        query += " order by ";
        query += "   m.startDate desc, m.idMaintenance desc";
        return super.list(query, "name", name);
    }

以下是我的例外

由以下原因引起：org.hibernate.hql.internal.ast.QuerySyntaxException：__Maintenance未映射[从__Maintenance m中选择m，其中m.name =：name由m.startDate desc，m.idMaintenance desc顺序排列] 在org.hibernate.hql.internal.ast.QuerySyntaxException.generateQueryException（QuerySyntaxException.java:79）在org.hibernate.QueryException.wrapWithQueryString（QueryException.java:103）在org.hibernate.hql.internal.ast.QueryTranslatorImpl.doCompile（QueryTranslatorImpl.java:218）在org.hibernate.hql.internal.ast.QueryTranslatorImpl.compile（QueryTranslatorImpl.java:142）在org.hibernate.engine.query.spi.HQLQueryPlan。（HQLQueryPlan.java:115）在org.hibernate.engine.query.spi.HQLQueryPlan。（HQLQueryPlan.java:76）

该表似乎在配置中丢失。该表是在persistence.xml还是javaconfig文件中声明的？

升级到休眠5.1时出现QuerySyntaxException
