Question

如果我正在打印会话对象，则所需的输出不正确，即-

SessionImpl(PersistenceContext[entityKeys=[],collectionKeys=[]];ActionQueue[insertions=org.hibernate.engine.spi.ExecutableList@7164ee40 updates=org.hibernate.engine.spi.ExecutableList@2d80b7f deletions=org.hibernate.engine.spi.ExecutableList@560d3d76 orphanRemovals=org.hibernate.engine.spi.ExecutableList@10fbc8b2 collectionCreations=org.hibernate.engine.spi.ExecutableList@463b2203 collectionRemovals=org.hibernate.engine.spi.ExecutableList@47a5a48 collectionUpdates=org.hibernate.engine.spi.ExecutableList@3b23213c collectionQueuedOps=org.hibernate.engine.spi.ExecutableList@75d3c0b2 unresolvedInsertDependencies=UnresolvedEntityInsertActions[]])

如果这样打印，我认为很有价值-

SessionImpl(PersistenceContext[entityKeys=[EntityKey[com.mode
l.Entity#1]],collectionKeys=[]];ActionQueue[insertions=[] updates=[] deletions=[
] collectionCreations=[] collectionRemovals=[] collectionUpdates=[]])

我的Shop课程是-

@Entity
@Table(name = "shops")
public class Shop {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    @Column(name = "shop_domain")
    private String shopDomain;
    @JsonFormat(pattern="dd-MM-yyyy")
    private Timestamp orderSyncDate;
    @OneToOne(mappedBy = "shop", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JsonManagedReference
    private NetsuiteConfig netsuiteConfig;

我只是将一些数据设置为shop类对象，尝试保存到DB中，对象保留ID，即DB中已经存在，查询为- 会话factory.getCurrentSession（）。update（shop）; 这实际上不会更新db中的值，我不知道原因，为什么？

您必须提交更新，以使更改传播到数据库：
