随后进入判定
return this.invokeSaveLifecycle(entity, persister, source) ? id : this.performSaveOrReplicate(entity, key, persister, useIdentityColumn, anything, source, requiresImmediateIdAccess);
未通过persister.implementsLifecycle() 判定 返回了false
protected boolean invokeSaveLifecycle(Object entity, EntityPersister persister, EventSource source) {
if (persister.implementsLifecycle()) {
LOG.debug("Calling onSave()");
if (((Lifecycle)entity).onSave(source)) {
LOG.debug("Insertion vetoed by onSave()");
return true;
return false;
public boolean implementsLifecycle() {
return this.getEntityTuplizer().isLifecycleImplementor();
自定义策略
* 当新数据指定了自定义id时 使用自定义id
