Hibernate Mapping - Converting XML to Annotation - Wrong Column name being generated - spring

Question

I have a two projects in hibernate one is for XML and one is for annotation.
My XML Mapping config works fine with composite keys while the annotation style generates a wrong column.
Annotation Style Generates this table
Hibernate: create table agent (agent_id number(10,0) not null, start_dttm timestamp not null, agent_cd varchar2(255 char), end_dttm timestamp, primary key (agent_id, start_dttm))
Hibernate: create table agent_license (agent_license_id number(10,0) not null, agent_agent_id number(10,0), agent_start_dttm timestamp, agent_id number(10,0), primary key (agent_license_id))
Hibernate: alter table agent_license add constraint FKncan0jjmt1siq0a6a19ll978m foreign key (agent_agent_id, agent_start_dttm) references agent
Hibernate: alter table agent_license add constraint FKp64d6078jnxi3hq0n0es0yhs foreign key (agent_id, agent_start_dttm) references agent
a redundant column for AgentLicense with agent_agent_id instead of agent_id only.
This is Working Correctly XML Config
XML generates
Agent Table with column agent_id,start_dttm,agent_cd
Agent_License with column agent_id,agent_start_dttm
Agent Model
<class name="com.poc.model.Agent" table="AGENT">
<composite-id name="id" class="com.poc.model.pk.AgentPK">
<key-property name="agentId" type="long">
<column name="AGENT_ID" precision="10" scale="0" />
</key-property>
<key-property name="startDateTime" type="timestamp">
<column name="START_DTTM" />
</key-property>
</composite-id>
<property name="agentCode" type="string">
<column name="AGENT_CD" length="20" />
</property>
<set name="agentLicenses" table="AGENT_LICENSE" inverse="true" lazy="true" fetch="select">
<key>
<column name="AGENT_ID" precision="10" scale="0" />
<column name="AGENT_START_DTTM" />
</key>
<one-to-many class="com.poc.model.AgentLicense" />
</set>
</class>
AgentLicense Model
<class name="com.poc.model.AgentLicense" table="AGENT_LICENSE">
<id name="agentLicenseId" type="long">
<column name="AGENT_LICENSE_ID" precision="10" scale="0" />
<generator class="assigned" />
</id>
<many-to-one name="agent" class="com.poc.model.Agent" fetch="select">
<column name="AGENT_ID" precision="10" scale="0" />
<column name="AGENT_START_DTTM" />
</many-to-one>
<property name="licenseNum" type="string">
<column name="LICENSE_NUM" length="40" />
</property>
</class>
Agent PK Model
<class name="com.poc.model.Agent" table="AGENT">
<composite-id name="id" class="com.poc.model.pk.AgentPK">
<key-property name="agentId" type="long">
<column name="AGENT_ID" precision="10" scale="0" />
</key-property>
<key-property name="startDateTime" type="timestamp">
<column name="START_DTTM" />
</key-property>
</composite-id>
<property name="agentCode" type="string">
<column name="AGENT_CD" length="20" />
</property>
<set name="agentLicenses" table="AGENT_LICENSE" inverse="true" lazy="true" fetch="select">
<key>
<column name="AGENT_ID" precision="10" scale="0" />
<column name="AGENT_START_DTTM" />
</key>
<one-to-many class="com.poc.model.AgentLicense" />
</set>
</class>
Correct Annotation is this
Result table generation
Agent Table with column agent_id,start_dttm,agent_cd
Agent_License with column agent_id,agent_start_dttm
public class Agent {
#EmbeddedId
#AttributeOverrides({
#AttributeOverride(name = "agentId", column = #Column(name = "AGENT_ID", nullable = false)),
#AttributeOverride(name = "startDateTime", column = #Column(name = "START_DTTM", nullable = false)) })
private AgentPK agentPK;
#Column(name="AGENT_CODE")
private String agentCode;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "agent")
private Set<AgentLicense> agentLicenses = new HashSet<AgentLicense>();
}
public class AgentLicense {
#Id
#Column(name = "AGENT_LICENSE_ID", unique = true, nullable = false)
private long agentLicenseId;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumns({ #JoinColumn(name = "AGENT_ID", referencedColumnName = "AGENT_ID"),
#JoinColumn(name = "AGENT_START_DTTM", referencedColumnName = "START_DTTM") })
private Agent agent;
}
#Embeddable
public class AgentPK implements Serializable{
#Column(name = "AGENT_ID", nullable = false, precision = 10, scale = 0)
private long agentId;
#Column(name = "START_DTTM", nullable = false)
#Temporal(TemporalType.TIMESTAMP)
private Date startDateTime;
//HashCode and equals here
}
Correct Full answer

Answer 1

Fix your inverse mapping for AgentLicense in Agent
public class Agent {
// ...
#OneToMany(mappedBy = "agent")
#JoinColumns( ... )
private Set<AgentLicense> agentLicenses;
}
