下午增加數(shù)據(jù)庫(kù)字段的時(shí)候出現(xiàn)了這個(gè)問(wèn)題：
org.springframework.orm.jpa.JpaSystemException: could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize
……
Caused by: org.hibernate.type.SerializationException: could not deserialize
……
Caused by: java.io.EOFException
……
原因：一些外鍵關(guān)聯(lián)的字段注解寫(xiě)錯(cuò)了赐俗。
@Column(name = "mch_id")
private Mch mch;
修改為：
@JoinColumn(name = "mch_id", referencedColumnName = "id", nullable = false, updatable=false)
@ManyToOne(optional = false, targetEntity = Mch.class)
private Mch mch;
