错误的列类型遇到用户定义的数据类型

Question

我正在使用hibernate从SQL Server 2014数据库中获取一些数据。

有具有用户定义的数据类型的列的表：

dbo.Nodos 
    Id (PK, int, not null) 
    Tipo (PK, FK, TipoNodo(tinyint), not null) 
    Nombre (varchar(40), null) 
    PosX (Coordenada(real), not null) 
    PosY (Coordenada(real), not null) 
    Label (varchar(8), not null) 

这些数据类型是Coordenada和TipoNodo：

User-Defined Data Types 
    dbo.Coordenada (real, not null) 
    dbo.TipoNodo (tinyint, not null) 

我映射Nodos表作为StopDTO类Java：

@Entity 
@Table(name = "Nodos") 
public class StopDTO { 

    /* 
    * Atributos 
    */ 
    @Id 
    @Column(name = "Id", insertable = false, updatable = false) 
    private Integer id; 
    @Column(name = "Tipo", insertable = false, updatable = false) 
    private Integer tipo; 
    @Column(name = "Nombre", insertable = false, updatable = false) 
    private String nombre; 
    @Column(name = "PosX", insertable = false, updatable = false) 
    private Float posx; 
    @Column(name = "PosY", insertable = false, updatable = false) 
    private Float posy; 
    @Column(name = "Label", insertable = false, updatable = false) 
    private String label; 
    ... 

问题出现在我查询StopDTOs（使用NamedNativeQuery）时，我刚刚克以下消息：

所致：org.hibernate.tool.schema.spi.SchemaManagementException： 架构验证：在柱[POSX]遇到 表[Nodos]错列类型;发现[coordenada（类型＃REAL）]，但期待在 org.hibernate.tool.schema.internal.SchemaValidatorImpl.validateColumnType（SchemaValidatorImpl.java:165） [漂浮 （类型＃FLOAT）]在 org.hibernate作为。 tool.schema.internal.SchemaValidatorImpl.validateTable（SchemaValidatorImpl.java:150） 在 org.hibernate.tool.schema.internal.SchemaValidatorImpl.performValidation（SchemaValidatorImpl.java:95） 在 org.hibernate.tool.schema。 internal.SchemaValidatorImpl.doValidation（SchemaValidatorImpl.java:62） ...

这方面的问题通过实施解决Coordenada和TipoNodo的UserType几个？如果不是，我该怎么办？

谢谢！

解决！

事实上，这是预期的：开发一对UserType。万一有人需要我会后的代码：

TipoNodoUserType

package com.mycompany.usertype; 
import java.io.Serializable; 
import java.sql.PreparedStatement; 
import java.sql.ResultSet; 
import java.sql.SQLException; 
import java.sql.Types; 
import java.util.Objects; 

import org.hibernate.HibernateException; 
import org.hibernate.engine.spi.SessionImplementor; 
import org.hibernate.type.descriptor.java.ShortTypeDescriptor; 
import org.hibernate.usertype.UserType; 

public class TipoNodoUserType implements UserType { 

    public static final TipoNodoUserType INSTANCE = new TipoNodoUserType(); 

    @Override 
    public int[] sqlTypes() { 
     return new int[] {Types.TINYINT}; 
    } 

    @SuppressWarnings("rawtypes") 
    @Override 
    public Class returnedClass() { 
     return Short.class; 
    } 

    @Override 
    public boolean equals(Object x, Object y) throws HibernateException { 
     return Objects.equals(x, y); 
    } 

    @Override 
    public int hashCode(Object x) throws HibernateException { 
     return Objects.hashCode(x); 
    } 

    @Override 
    public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) 
      throws HibernateException, SQLException { 
     String columnName = names[0]; 
     Short columnValue = (Short) rs.getObject(columnName); 
     return columnValue == null ? null : columnValue; 
    } 

    @Override 
    public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) 
      throws HibernateException, SQLException { 
     if(value == null){ 
      st.setNull(index, Types.TINYINT); 
     }else{ 
      String stringValue = ShortTypeDescriptor.INSTANCE.toString((Short)value); 
      st.setString(index, stringValue); 
     } 
    } 

    @Override 
    public Object deepCopy(Object value) throws HibernateException { 
     return value; 
    } 

    @Override 
    public boolean isMutable() { 
     return true; 
    } 

    @Override 
    public Serializable disassemble(Object value) throws HibernateException { 
     return (Serializable) value; 
    } 

    @Override 
    public Object assemble(Serializable cached, Object owner) throws HibernateException { 
     return cached; 
    } 

    @Override 
    public Object replace(Object original, Object target, Object owner) throws HibernateException { 
     return original; 
    } 

} 

CoordenadaUserType

package com.mycompany.usertype; 
import java.io.Serializable; 
import java.sql.PreparedStatement; 
import java.sql.ResultSet; 
import java.sql.SQLException; 
import java.sql.Types; 
import java.util.Objects; 

import org.hibernate.HibernateException; 
import org.hibernate.engine.spi.SessionImplementor; 
import org.hibernate.type.descriptor.java.FloatTypeDescriptor; 
import org.hibernate.usertype.UserType; 

public class CoordenadaUserType implements UserType { 

    public static final CoordenadaUserType INSTANCE = new CoordenadaUserType(); 

    @Override 
    public int[] sqlTypes() { 
     return new int[] {Types.REAL}; 
    } 

    @SuppressWarnings("rawtypes") 
    @Override 
    public Class returnedClass() { 
     return Float.class; 
    } 

    @Override 
    public boolean equals(Object x, Object y) throws HibernateException { 
     return Objects.equals(x, y); 
    } 

    @Override 
    public int hashCode(Object x) throws HibernateException { 
     return Objects.hashCode(x); 
    } 

    @Override 
    public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) 
      throws HibernateException, SQLException { 
     String columnName = names[0]; 
     Float columnValue = (Float) rs.getObject(columnName); 
     return columnValue == null ? null : columnValue; 
    } 

    @Override 
    public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) 
      throws HibernateException, SQLException { 
     if(value == null){ 
      st.setNull(index, Types.REAL); 
     }else{ 
      String stringValue = FloatTypeDescriptor.INSTANCE.toString((Float)value); 
      st.setString(index, stringValue); 
     } 
    } 

    @Override 
    public Object deepCopy(Object value) throws HibernateException { 
     return value; 
    } 

    @Override 
    public boolean isMutable() { 
     return true; 
    } 

    @Override 
    public Serializable disassemble(Object value) throws HibernateException { 
     return (Serializable) value; 
    } 

    @Override 
    public Object assemble(Serializable cached, Object owner) throws HibernateException { 
     return cached; 
    } 

    @Override 
    public Object replace(Object original, Object target, Object owner) throws HibernateException { 
     return original; 
    } 

} 

StopDTO

@Entity 
@Table(name = "Nodos") 
public class StopDTO implements java.io.Serializable{ 

    /* 
    * Atributos 
    */ 
    private static final long serialVersionUID = 8171715812406080593L; 

    @Id 
    @Column(name = "Id", insertable = false, updatable = false) 
    private Integer id; 
    @Id 
    @Column(name = "Tipo", insertable = false, updatable = false) 
    @Type(type = "com.mycompany.usertype.TipoNodoUserType") 
    private Short tipo; 
    @Column(name = "Nombre", insertable = false, updatable = false) 
    private String nombre; 
    @Column(name = "PosX", insertable = false, updatable = false) 
    @Type(type = "com.mycompany.usertype.CoordenadaUserType") 
    private Float posx; 
    @Column(name = "PosY", insertable = false, updatable = false) 
    @Type(type = "com.mycompany.usertype.CoordenadaUserType") 
    private Float posy; 
    @Column(name = "Label", insertable = false, updatable = false) 
    private String label; 
    ... 
    // Don't forget to code an empty constructor, setters/getters for every attribute and implementing hashCode and equals methods (as we're implementing Serializable interface). 

Answer 2

请检查在Hibernate中配置的方言，它应该是SQLServer2008Dialect。
