Hello Everyone,
I am using enum plus long field as my composite primary key in a model. But when I use both of the fields in jpql for filter criteria (e.g. where modelId = ?1 and vendorType = ?2) it gives me a ConversionException. Appreciate if someone can clarify. Below are the details:
VendorView:
@MappedSuperclass
@IdClass(VendorPK.class)
public abstract class VendorView extends AbstractView {
private static final long serialVersionUID = 4952393420338697658L;
@Id
@Column(name="MODEL_XID")
protected Long modelId;
@Id
@Enumerated
@Column(name="VENDOR_TYPE")
protected VendorType vendorType;
@Column(name="CODE")
@ReportElement(name="Code",dataType=DataType.TEXT,filter=true,index=1,sort=true,zlist=true,width=75)
protected String code;
@Column(name="SHORT_NAME")
@ReportElement(name="Short Name",dataType=DataType.TEXT,filter=true,index=1,sort=true)
protected String shortName;
@Column(name="TITLE")
@ReportElement(name="Title",dataType=DataType.TEXT,filter=true,index=0,sort=true,zlist=true,width=200)
protected String title;
@Column(name="DESCRIPTION")
protected String description;
@Column(name="APPLY_CHARGES")
@ReportElement(name="Apply charges",dataType=DataType.BOOLEAN,filter=true,index=3,sort=true)
protected Boolean applyCharges;
@Column(name="ADDRESS1")
@ReportElement(name="Address",dataType=DataType.TEXT,filter=false,index=4,sort=false)
protected String address1;
@Column(name="ADDRESS2")
protected String address2;
@Column(name="PHONE1")
@ReportElement(name="Phone",dataType=DataType.TEXT,filter=false,index=5,sort=false)
protected String phone1;
@Column(name="PHONE2")
protected String phone2;
@Column(name="FAX")
@ReportElement(name="Fax",dataType=DataType.TEXT,filter=false,index=6,sort=false)
protected String fax;
public Long getModelId() {
return modelId;
}
public String getCode() {
return code;
}
public String getShortName() {
return shortName;
}
public String getTitle() {
return title;
}
public String getDescription() {
return description;
}
public Boolean isApplyCharges() {
return applyCharges;
}
public String getAddress1() {
return address1;
}
public String getAddress2() {
return address2;
}
public String getPhone1() {
return phone1;
}
public String getPhone2() {
return phone2;
}
public String getFax() {
return fax;
}
public VendorType getVendorType() {
return vendorType;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((modelId == null) ? 0 : modelId.hashCode());
result = prime * result
+ ((vendorType == null) ? 0 : vendorType.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (getClass() != obj.getClass())
return false;
VendorView other = (VendorView) obj;
if (modelId == null) {
if (other.modelId != null)
return false;
} else if (!modelId.equals(other.modelId))
return false;
if (vendorType == null) {
if (other.vendorType != null)
return false;
} else if (!vendorType.equals(other.vendorType))
return false;
return true;
}
}
VendorPk:
@Embeddable
public class VendorPK implements Serializable{
private static final long serialVersionUID = 2313226839954294852L;
@Column(name="MODEL_XID")
protected Long modelId;
@Column(name="VENDOR_TYPE")
@Enumerated
protected VendorType vendorType;
public VendorPK(){}
public VendorPK(Long modelId, VendorType vendorType){
this.modelId = modelId;
this.vendorType = vendorType;
}
public Long getModelId() {
return modelId;
}
public void setModelId(Long modelId) {
this.modelId = modelId;
}
public VendorType getVendorType() {
return vendorType;
}
public void setVendorType(VendorType vendorType) {
this.vendorType = vendorType;
}
public int hashCode() {
return (int)(Long.valueOf(modelId).hashCode()) + this.vendorType.hashCode();
}
public boolean equals(Object obj) {
if (obj == null) return false;
if (obj == this) return true;
if (!(obj instanceof VendorPK)) return false;
VendorPK pk = (VendorPK) obj;
return ((pk.modelId==this.modelId) && pk.vendorType.equals(this.vendorType));
}
}
AirlineView:
@Entity
@Table(name="GBOSSV_VENDOR")
@SecurityContext(value=Airline.class)
public class AirlineView extends VendorView {
private static final long serialVersionUID = 2969582818437459745L;
@Column(name="DIGIT_CODE")
@ReportElement(name="Digit Code",dataType=DataType.TEXT,width=50,filter=true,index=7,sort=true,zlist=true)
protected String digitCode;
@Column(name="CHARACTER_CODE")
@ReportElement(name="Character Code",dataType=DataType.TEXT,width=50,filter=true,index=8,sort=true,zlist=true)
protected String characterCode;
@Column(name="IS_IATA")
@ReportElement(name="Is IATA",dataType=DataType.BOOLEAN,filter=true,index=9,sort=true)
protected Boolean IATA;
public String getDigitCode() {
return digitCode;
}
public String getCharacterCode() {
return characterCode;
}
public Boolean getIATA() {
return IATA;
}
}
Jpql:
SELECT m FROM AirlineView m WHERE m.modelId =?1 and m.vendorType = ?2 ORDER BY m.vendorType,m.modelId ASC
