Java 无法使用复合键持久化实体
我正在尝试持久化具有合成主键的实体。。 这是我的员工实体 这是EvaluationEvaluatorsId类：Java 无法使用复合键持久化实体,java,hibernate,jpa,ejb,conversation-scope,Java,Hibernate,Jpa,Ejb,Conversation Scope,我正在尝试持久化具有合成主键的实体。。 这是我的员工实体 这是EvaluationEvaluatorsId类： public class EvaluationEvaluatorsId implements Serializable { private Long employeeID; private Long evaluationID; 这是我保存的方法 public String save() { Iterator<Employee> iterator =
public class EvaluationEvaluatorsId implements Serializable {
private Long employeeID;
private Long evaluationID;
public String save() {
Iterator<Employee> iterator = evaluators.getTarget().iterator();
while(iterator.hasNext()){
EvaluationEvaluator ev = new EvaluationEvaluator();
ev.setEmployee(iterator.next());
ev.setEvaluation(evaluation);
ev.setStatus("COMPLETED");
evaluation.getEvaluationEvaluators().add(ev);
}
if (evaluation.getId() == null) {
em.persist(evaluation);
} else {
em.merge(evaluation);
}
if (!conversation.isTransient()) {
conversation.end();
}
return "/evaluation/evaluationsAsig.xhtml";
Iterator Iterator=evaluators.getTarget（）.Iterator（）中的求值器是如何工作的检索？请共享实际的stacktrace。我通过DualList检索，因为在我的网页中我使用pick list，它需要这个组件来处理它。我已从数据库中检索到员工列表，但我想保存EvaluationEvator列表。我会发布完整的stacktrace。我调试了应用程序，显然一切正常。谢谢。我编辑了我的问题并添加了stacktrace，提前谢谢。我在这里遇到了同样的问题，你解决了吗？
