错误
Hibernate: select this_.UID as y0_, this_.PATH as y1_, this_.NAME as y2_ from AWARD this_ where this_.DELETED=?
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Boolean
Hibernate代码
criteria.add(Restrictions.eq("deleted", 0));
criteria.setProjection(Projections.projectionList().add(Projections.property("uid"))
.add(Projections.property("path")).add(Projections.property("name"))).
setResultTransformer(Transformers.aliasToBean(AwardsInSession.class));
List<AwardsInSession> la = criteria.list();
Custorm POJO
public class AwardsInSession extends BaseModel{
private String uid;
private String path;
private String name;
在JPA实体中,这3个是字符串类型

修正了它,以下代码有效。当我们使用Transformers.aliasToBean时,条件构建中的每个列都应该有一个别名
criteria
.add(Restrictions.eq("deleted", Boolean.FALSE))
.add(Restrictions.eq("orgId.id", orgId))
.setProjection(Projections.projectionList()
.add(Projections.alias(Projections.property("path"), "path"))
.add(Projections.alias(Projections.property("uid"), "uid"))
.add(Projections.alias(Projections.property("name"), "name")))
.setResultTransformer(Transformers.aliasToBean(AwardsInSession.class));

在您的Award实体中,您将deleted
属性字段定义为布尔值。
因此,你的限制应该是:
criteria.add(Restrictions.eq("deleted", Boolean.FALSE));
