Java 无法使用Spring数据JPA创建自定义用户类型

java spring spring-boot hibernate jpa

Java 无法使用Spring数据JPA创建自定义用户类型,java,spring,spring-boot,hibernate,jpa,Java,Spring,Spring Boot,Hibernate,Jpa,我正在尝试为我的数据库创建一个名为CompanyType的自定义用户类型。我将使用它只存储一个唯一的字符串作为最终对象的标识符（在代码中它是合法的和单独的）公司类型的完整类别： public class CompanyType implements UserType { private String typeId; private String typeName; public static final CompanyType LEGAL = new Company

我正在尝试为我的数据库创建一个名为CompanyType的自定义用户类型。我将使用它只存储一个唯一的字符串作为最终对象的标识符（在代码中它是合法的和单独的）

公司类型的完整类别：

public class CompanyType implements UserType {

    private String typeId;
    private String typeName;

    public static final CompanyType LEGAL = new CompanyType("LEGAL", "Some legal type");
    public static final CompanyType INDIVIDUAL = new CompanyType("INDIVIDUAL", "Some individual type");

    public CompanyType(String typeId, String typeName) {
        this.typeId = typeId;
        this.typeName = typeName;
    }

    public String getTypeId() {
        return typeId;
    }

    public String getTypeName() {
        return typeName;
    }

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

    @Override
    public Class returnedClass() {
        return String.class;
    }

    @Override
    public boolean equals(Object o, Object o1) throws HibernateException {
        return o.equals(o1);
    }

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

    @Override
    public Object nullSafeGet(ResultSet resultSet, String[] strings, SharedSessionContractImplementor sharedSessionContractImplementor, Object o) throws HibernateException, SQLException {
        if(resultSet.getString(strings[0]).equals("LEGAL")) return LEGAL;
        else return INDIVIDUAL;
    }

    @Override
    public void nullSafeSet(PreparedStatement preparedStatement, Object o, int i, SharedSessionContractImplementor sharedSessionContractImplementor) throws HibernateException, SQLException {
        preparedStatement.setString(i, this.getTypeId());
    }

    @Override
    public Object deepCopy(Object o) throws HibernateException {
        CompanyType toCopy = (CompanyType) o;
        return new CompanyType(toCopy.getTypeId(), toCopy.getTypeName());
    }

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

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

    @Override
    public Object assemble(Serializable serializable, Object o) throws HibernateException {
        return serializable;
    }

    @Override
    public Object replace(Object o, Object o1, Object o2) throws HibernateException {
        return deepCopy(o);
    }
}

然后我尝试在我的实体-contracent.java中使用它

@Entity
public class Contragent {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private String name;
    private String INN;
    private String OGRN;

    @Type(type = "com.test.test1.CompanyType")
    private CompanyType companyType;

... other code

当我运行项目时，它会打印一个异常：
