【问题描述】：
我在引用此查询时遇到问题。在 Postgres 上，这个查询执行没有错误。在 JAVA 上，它会抛出以下异常：
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not extract ResultSet
cause
org.postgresql.util.PSQLException: ERROR: operator does not exist: uuid = bytea
Note: No operator matches the given name and argument type(s). You might need to add explicit type casts.
Position: 404
我要做什么？
我的方法：
public List<CivilRecord> dashboardSearch(CivilRecordSearch civilRecordSearch)
throws MessageException {
SearchValidation.validateDashboardSearch(civilRecordSearch);
List<CivilRecord> l = new ArrayList<>();
try {
StringBuilder query = new StringBuilder();
// query.append("select
// c.id_civil_record\\:\\:text,c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority
// ");
query.append("select c.id_civil_record,c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority ");
query.append("from sc_civil.tb_civil_record c ");
query.append("inner join sc_civil.tb_workflow_record w ");
query.append("on w.id_civil_record = c.id_civil_record ");
query.append("left join sc_civil.tb_lock l ");
query.append("on l.id_record = c.id_civil_record ");
query.append("where c.id_site = :idSite ");
if (civilRecordSearch.getPriority() == null || civilRecordSearch.getPriority().equals(false))
query.append("and c.bl_priority = :priority ");
query.append("and c.bl_canceled = :canceled ");
query.append("and w.id_type_workflow = :idTypeWorkflow ");
query.append("and w.id_type_status_workflow = :idTypeStatusWorkflow ");
query.append("and (l is null or l.id_user = :idUser) ");
if (!StringUtils.isEmpty(civilRecordSearch.getName()))
query.append("and c.tx_name ilike :name ");
if (!StringUtils.isEmpty(civilRecordSearch.getRg()))
query.append("and c.nm_rg like :rg ");
if (civilRecordSearch.getRequestNumber() != null)
query.append("and c.nm_request = :request ");
query.append("order by c.bl_priority desc, c.dt_register ");
Query q = em.createNativeQuery(query.toString());
q.setParameter("idSite", civilRecordSearch.getSite().getId());
if (civilRecordSearch.getPriority() == null || civilRecordSearch.getPriority().equals(false))
q.setParameter("priority", false);
q.setParameter("idTypeWorkflow", civilRecordSearch.getTypeworkflow().getId());
q.setParameter("idTypeStatusWorkflow", civilRecordSearch.getTypestatusworkflow().getId());
q.setParameter("idUser", civilRecordSearch.getIdUser());
q.setParameter("canceled", false);
if (!StringUtils.isEmpty(civilRecordSearch.getName()))
q.setParameter("name", "%" + civilRecordSearch.getName() + "%");
if (civilRecordSearch.getRequestNumber() != null)
q.setParameter("request", civilRecordSearch.getRequestNumber());
if (!StringUtils.isEmpty(civilRecordSearch.getRg()))
q.setParameter("rg", civilRecordSearch.getRg());
q.setMaxResults(maxResult);
List<Object []> lo = q.getResultList();
em.clear();
for (Object [] o : lo) {
CivilRecord c = new CivilRecord();
c.setIdCivilRecord(UUID.fromString((String) o[0]));
c.setRequest((Long) o[1]);
c.setRg((String) o[2]);
c.setName((String) o[3]);
c.setWorkflowRecords(findStatus(c.getIdCivilRecord()));
l.add(c);
}
return l;
}
catch (Exception e) {
log.severe(e.getMessage());
throw e;
}
}
我的班级 CivilRecordSearch：
import java.io.Serializable;
import java.util.UUID;
public class CivilRecordSearch implements Serializable {
private static final long serialVersionUID = 1701325902333490974L;

private Long requestNumber;
public Site getSite() {
return site;
}
public void setSite(Site site) {
this.site = site;
}
public Boolean getPriority() {
return priority;
}
public void setPriority(Boolean priority) {
this.priority = priority;
}
public TypeWorkflow getTypeworkflow() {
return typeworkflow;
}
public void setTypeworkflow(TypeWorkflow typeworkflow) {
this.typeworkflow = typeworkflow;
}
public TypeStatusWorkflow getTypestatusworkflow() {
return typestatusworkflow;
}
public void setTypeStatusWorkflow(TypeStatusWorkflow typestatusworkflow) {
this.typestatusworkflow = typestatusworkflow;
}
public static long getSerialversionuid() {
return serialVersionUID;
}
public Integer getAmount() {
return amount;
}
public void setAmount(Integer amount) {
this.amount = amount;
}
public UUID getIdUser() {
return idUser;
}
public void setIdUser(UUID idUser) {
this.idUser = idUser;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRg() {
return rg;
}
public void setRg(String rg) {
this.rg = rg;
}
public Long getRequestNumber() {
return requestNumber;
}
public void setRequestNumber(Long requestNumber) {
this.requestNumber = requestNumber;
}
}
【问题讨论】：
-
数据库中
tb_lock.idUser是什么类型？你可以试试q.setParameter("idUser", civilRecordSearch.getIdUser().toString())吗？ -
tb_lock.iduser 是 UUID 在数据库中。
-
你在使用休眠吗？注释？
-
是的。我正在使用休眠
