Spring hibernate中的UUID映射

我已将一个表映射到我的表，并尝试在其中添加一些值。但我得到的错误如下

原因：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException： 您的SQL语法有错误；检查手册 对应于您的MySQL服务器版本，以便使用正确的语法 近“创建、删除、读取、角色\u id、更新、id）值 （"二元"N"WlAs€“\niÊNÙ' 在1号线

我的实体是

我的json对象

{ "roleId" :{"id":  "b2e64c82-ab75-41d3-bb10-e9150f314807"} }

---

“我的角色id”作为类型二进制（16）存储在数据库中。

请检入

id

列的数据库数据类型。它必须是

binary（16）

。并将实体字段注释为：

@Id
@GeneratedValue(generator = "uuid2")
@GenericGenerator(name = "uuid2", strategy = "org.hibernate.id.UUIDGenerator")
@Column(columnDefinition = "BINARY(16)")
private UUID id;

---

请注意，在这种情况下，您需要添加列定义。

尝试将

@column（columnDefinition=“BINARY（16）”）

添加到

id

字段和默认字符集UTF-8@benjamin-c尝试了这两种方法，但仍然得到相同的错误。尝试了它，仍然得到与以前相同的错误。
