【问题描述】：
在我的应用程序中使用 derby 嵌入式数据库时遇到以下问题：
我更改了一个与 Mysql 数据库一起使用的程序以使用 Derby 嵌入式数据库，因为由于 Internet 问题，客户想要这样，一切正常，但是当我想使用一系列日期进行搜索时控制台显示下一个错误：
2018-12-10 17:26:18.920 INFO 107044 --- [nio-7009-exec-3]

org.apache.derby.iapi.error.StandardException: The syntax of the string representation of a date/time value is incorrect.
就像我在使用 MySql 时所说的那样，它可以完美运行。
我使用的查询是这样的：
@SuppressWarnings("unchecked")
@RequestMapping(value = "/transferencias/consultatodos", method = RequestMethod.POST, produces = "application/json; charset=utf-8")
@CrossOrigin
@RequestScope
Collection<Transferencias> transferenciasConsultastodos(@RequestBody Consulta conf) throws JsonProcessingException {
List<Transferencias> transl = new ArrayList<>();
log.info("/transferencias/consultar");
String Query = "Select trans from Transferencias trans";
if (conf.getFecha1() != null && conf.getFecha2() != null) {
Query = Query + " WHERE trans.fecha >= '" + conf.getFecha1() + "' AND trans.fecha<= '"+conf.getFecha2()+"'";
if (conf.getBanco() != null) {
Query = Query + " AND trans.banco = '" + conf.getBanco() +"'";
}
if (conf.getBeneficiario() != null) {
Query = Query + " AND trans.beneficiario = '" + conf.getBeneficiario() +"'";
}
if (conf.getTipo() != null) {
Query = Query + " AND trans.tipo = '" + conf.getTipo() +"'";
}
}
else {
if (conf.getBanco() != null) {
Query = Query + " WHERE trans.banco = '" + conf.getBanco() +"'";
if (conf.getBeneficiario() != null) {
Query = Query + " AND trans.beneficiario = '" + conf.getBeneficiario() +"'";
}
if (conf.getTipo() != null) {
Query = Query + " AND trans.tipo = '" + conf.getTipo() +"'";
}
}
else {
if (conf.getBeneficiario() != null) {
Query = Query + " WHERE trans.beneficiario = '" + conf.getBeneficiario() +"'";
if (conf.getTipo() != null) {
Query = Query + " AND trans.tipo = '" + conf.getTipo() +"'";
}
}
else {
if (conf.getTipo() != null) {
Query = Query + " WHERE trans.tipo = '" + conf.getTipo() +"'";
}
}
}
}
transl = em.createQuery(Query).getResultList();
return transl;
}
当我使用其他参数进行搜索时，它工作得很好，问题出在日期上。
实体：
package ControlTransferencias.wDatos;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
/**

* @author juan.finol
*/
@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Transferencias {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
private Long referencia;
private String beneficiario;
private String banco;
private Date fecha;
private String notaAdicional;
private String descripcion;
private Long monto;
private String tipo;
public String getTipo() {
return tipo;
}
public void setTipo(String tipo) {
this.tipo = tipo;
}
public Long getReferencia() {
return referencia;
}
public void setReferencia(Long referencia) {
this.referencia = referencia;
}
public String getBeneficiario() {
return beneficiario;
}
public void setBeneficiario(String beneficiario) {
this.beneficiario = beneficiario;
}
public String getBanco() {
return banco;
}
public void setBanco(String banco) {
this.banco = banco;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getDescripcion() {
return descripcion;
}
public void setDescripcion(String descripcion) {
this.descripcion = descripcion;
}
public Date getFecha() {
return fecha;
}
public void setFecha(Date fecha) {
this.fecha = fecha;
}
public Long getMonto() {
return monto;
}
public void setMonto(Long monto) {
this.monto = monto;
}
public String getNotaAdicional() {
return notaAdicional;
}
public void setNotaAdicional(String notaAdicional) {
this.notaAdicional = notaAdicional;
}
}
我注意到的另一件事是在前端，当我进行搜索时，它会显示如下日期：1544414400000，而当我使用 MySql 时，它会显示 dd-mm-yyyy 格式。
注意：后端是用spring boot制作的。
