Question

我有一个Entity类，其中包含许多属性。

Hibernate在Spring引导初始化期间通过Hibernate AnnotationBinder正确发现属性，并且值从我们的数据库中正确获取，并通过Hibernate BasicExtractor正确映射到对象。

然而，在访问属性时，它们的值似乎来自过时的缓存版本。例如，它的值始终为null，而不是提取器日志中显示的值，我似乎无法弄清楚原因。值得注意的是：我可以保存到这个属性并让它保持正确，我只是不能从中读取

WHTFMain班

@Entity
@Table(name = "whtf_main")
public class WHTFMain {
     ...
     @Column(nullable = true)
     private String netsuiteId;
     ....
     // getter/setter not shown
 }

注释活页夹日志：

基本提取器日志（503是正确的值）

[ThreadPoolTaskScheduler-3] TRACE org.hibernate.type.descriptor.sql.BasicExtractor - extracted value ([netsuite8_1_1_] : [VARCHAR]) - [503]

查询：

public List<WHTFMain> findByMongoId(String mongoId) {
    return entityManager.createQuery("select w from WHTFMain w where mongoId = :mongoId", WHTFMain.class)
            .setParameter("mongoId",mongoId)
            .getResultList();
}

被叫：

List<WHTFMain> whtfMainList = whtfDAO.findByMongoId(whtfMain.getMongoId());

检查：

netsuiteId = null

属性在具有值的hibernate跟踪日志中显示，但值未映射到对象属性
