------------------------------------
Summary: Olingo V2 makes exception on entities with ManyToMany
relationships
Key: OLINGO-1467
URL: https://issues.apache.org/jira/browse/OLINGO-1467
Project: Olingo
Issue Type: Bug
Components: odata2-jpa
Affects Versions: V2 2.0.11
Environment: Spring-boot, Hibernate
Reporter: Mahdi Ansari
I have made an OData server with Spring-boot, JPA, Hibernate and Olingo2.
There is a *{{ManyToMany}}* relationship between {{User}} and {{Role}} entities.
{code:java}
// In User entity
@ManyToMany(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST,
CascadeType.MERGE})
@JoinTable(name = "user_authority",
joinColumns = {@JoinColumn(name = "user_id", referencedColumnName =
"user_id")}, inverseJoinColumns = {@JoinColumn(name = "role_id",
referencedColumnName = "role_id")})
private Set<Role> roles = new HashSet<>();{code}
and
{code:java}
// In Role entity
//bi-directional many-to-many association to User
@ManyToMany(mappedBy="roles", fetch = FetchType.LAZY)
@JsonIgnore
private Set<User> users = new HashSet<>();{code}
I am using Olingo {{V2.0.11}} and spring boot version {{2.3.0.RELEASE}}.
When I try to see the list of Roles in my odata endpoint I can easily do it,
however when I try to see list of Users I get the following error:
{code:java}
<?xml version='1.0' encoding='UTF-8'?>
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";>
<code/>
<message xml:lang="en">Missing message for key
'org.apache.olingo.odata2.api.edm.EdmSimpleTypeException.PROPERTY_VALUE_FACETS_NOT_MATCHED'!</message>
</error>{code}
I am not sure the error comes from JPA or from Olingo. Anyone else has similar
experiences with Olingo V2 for defining ManyToMany relationship?
