Java Camel JMS更新JPA实体

当使用类似于下面的代码时，只要我从来没有一条记录使用与前一条记录相同的主键进入，一切都正常，但如果我收到一条具有相同主键的消息，我会得到一个无法插入异常。如果我得到一个具有相同主键的记录，是否有必要设置Jpa将插入转换为更新

from("jms:queue:myqueue")
    .unmarshal(myGsonDataFormat)
    .convertBodyTo(MyDBEntity.class)
    .to("jpa:" + MyDBEntity.class.getName());

@Entity
@Table(name = "MyTableName")
public class MyDBEntity {
    @Id
    @Column(name = "column1", length =2)
    private String column1;

    @Column(name = "column2", length =2)
    private String column2;

}

您可以尝试使用参数

usePersist=false

usePersist：Camel 2.5:JPA producer only:指示使用 entityManager.persist（实体）而不是entityManager.merge（实体）。 注意：entityManager.persist（实体
