this 这个
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id)")
public int getId() {
return id;
}
should be -
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id")
public int getId() {
return id;
}
Remove )
from the end of name="emp_id)"
从
name="emp_id)"
末尾删除)
There is typo error in the Id field emp_id, having extra ')' Id字段emp_id中存在拼写错误,且有多余的')'
@Column(name="emp_id)")
Remove the curly bracket it will work. 删除花括号将起作用。
column name for id you specified is containing ) remove it eg 您指定的ID的列名称包含)删除它,例如
replace @Column(name="emp_id)") with @Column(name="emp_id")
将
@Column(name="emp_id)") with @Column(name="emp_id")
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="emp_id")
