- 項(xiàng)目啟動報(bào)如下警告：
2020-07-30 15:54:59.681 WARN 11709 --- [ restartedMain] org.hibernate.id.UUIDHexGenerator : HHH000409: Using org.hibernate.id.UUIDHexGenerator which does not generate IETF RFC 4122 compliant UUID values; consider using org.hibernate.id.UUIDGenerator instead
意思是它不能生成符合IETF RFC 4122標(biāo)準(zhǔn)的UUID值，請考慮使用org.hibernate.id.UUIDGenerator幔摸。
1 原先的寫法
@Id
@GenericGenerator(name="idGenerator", strategy="uuid")
@GeneratedValue(generator="idGenerator")
private String id;
2 改為如下寫法
@Id
@GenericGenerator(name="uuid2", strategy="org.hibernate.id.UUIDGenerator")
@GeneratedValue(generator="uuid2")
private String id;
