我正在使用oracle 12c和hibernate-core 5.0.1.Final。
表结构如下
create table tracer (
id number(10,0) generated as identity,
creation_time timestamp,
request varchar2(4000 char),
requestor varchar2(255 char),
response varchar2(4000 char),
resp varchar2(4000 char),
type varchar2(255 char),
primary key (id)
)
Java Class具有id属性
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="id")
private Integer id;
当我尝试使用hibernate插入数据时，我会得到异常
ERROR: Invalid conversion requested
