[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6351) Enum Bug when using OK word inside of a enum being retrieved

Vlad Yatsenko commented on HHH-6351:
------------------------------------
Same is true for Hibernate 3.6.8.Final, and in my case HSQLDB 2.x.x. For an enum property
Hibernate creates a column of type CHARACTER which is a fixed length column (contrary to
VARCHAR). The length of it probably determined as a length of the longest enum value. When
values are read from the table those shorter values come out appended with white spaces.
Seems that adding trimming of a String value before converting into an enum type in
EnumType.nullSafeGet would fix the problem.
Enum Bug when using OK word inside of a enum being retrieved
------------------------------------------------------------
Key: HHH-6351
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6351
Project: Hibernate Core
Issue Type: Bug
Components: annotations
Affects Versions: 3.3.0.GA, 3.6.5
Environment: Hibernate version 3.3.0.GA, 3.6.5.Final with hibernate-annotations
3.4.0.GA. Oracle database.
Reporter: Lucas Arruda
Priority: Minor
I have a class with a field which is an enum, which is mapped by a enum called Status.
The class is described (simplified and without all annotations) above:
public class A {
private Status status;
public enum Status { OK, NOK, NAP }
@Column(name = "STATUS")
@Enumerated(EnumType.STRING)
public Status getStatus() {
return status;
}
...
}
The thing is. I can store a record from A with status = 'OK', 'NOK' or
'NAP' perfectly. But, when I try to retrieve that record, if status =
'NOK' or 'NAP' it works correctly, but no with status = 'OK',
which gives me an exception:
java.lang.IllegalArgumentException: Unknown name value for enum class
com.a.b.c.d.A$Status: OK
at org.hibernate.type.EnumType.nullSafeGet(EnumType.java:113)
...
Caused by: java.lang.IllegalArgumentException: No enum const class
com.a.b.c.d.A$Status.OK
at java.lang.Enum.valueOf(Enum.java:196)
at org.hibernate.type.EnumType.nullSafeGet(EnumType.java:110)
Reported a StackOverflow [1] and now one could solve this using 'OK' in the
Enum.
What I did to solve this, since I couldn't get I done with OK, was to change a little
bit the enum with this, which works correctly:
public enum Status {
_OK("OK"),
NOK("NOK"),
NAP("NAP");
private String desc;
public String getDesc() {
return desc;
}
private Status(String desc) {
this.desc = desc;
}
}
Since I couldn't make it work with 'OK', I highly suspect it's either a
big mistake by my part or a bug, so I'm reporting it.
