Currently I am upgrading an application from Hibernate 4 to Hibernate 5 (5.4.32), and hang on the following issue:
On startup of the application, when one of some data sources is initialized, I get the following exception:
Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'logger-entityManagerFactory' defined in URL [jar:file:/commons-functional-logging-service/2.0.99-SNAPSHOT/mvb-commons-functional-logging-service-2.0.99-SNAPSHOT.jar!/META-INF/spring/cfl-datasource.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: property [properties] not found on entity [xxx.model.MiscMessageProperties]

At no point in the XML-configuration the property "properties" is mentioned (and of course neither in the code). The configuration of "logger-entityManagerFactory" is as follows:
<bean id="logger-entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="logger-dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true" />
<property name="database" value="${cfl.database.dialect}" />
</bean>
</property>
<property name="jpaPropertyMap">
<map>
<entry key="javax.persistence.validation.factory" value-ref="validator" />
<entry key="hibernate.show_sql" value="${hibernate.show_sql}"/>
<entry key="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl}"/>
<entry key="org.hibernate.envers.revision_on_collection_change" value="true"/>
</map>
</property>
<property name="persistenceUnitName" value="xxx.commons.logging" />
<property name="persistenceUnitManager" ref="logger-persistenceUnitManager" />
</bean>
The mentioned class is found via the persistence.xml and looks like this:
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import de.mvbonline.commons.IdGenerator;
@Entity(name = "miscmessage_properties")
public class MiscMessageProperties {
@Id
private PropertiesKey propertiesKey = new PropertiesKey();
@Column(name = "properties", length = 256)
private String value;
public MiscMessageProperties() {
}
public String getId() {
return this.propertiesKey.getId();
}
public void setId(String id) {
this.propertiesKey.setId(id);
}
public String getKey() {
return this.propertiesKey.getKey();
}
public void setKey(String key) {
this.propertiesKey.setKey(key);
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
As far as I know it is not uncommon and allowed to use a different name for the property and the column name. I also found lots of examples for that which looked more or less like my code. The only known issue I stumbled upon was the use of @Index annotation on the same filed, which is not the case here. With Hibernate 4 this code worked somehow.
As this is a dependency which I cannot easily change I would prefer not to solve this by renaming either column or property. What can I do to solve this?
CodePudding user response：
I guess that you should correct this:
@Entity(name = "miscmessage_properties")
public class MiscMessageProperties {
...
to this:
import javax.persistence.Table;
@Entity
@Table(name="miscmessage_properties")
public class MiscMessageProperties {
...
if your intention was to define a table name for the entity MiscMessageProperties but not renaming the entity that is not necessary in common case.
See also this section of the hibernate documentation.
CodePudding user response：
Please correct as @SternK Suggested and remove assignment on @Id property as in
@Entity
@Table(name = "miscmessage_properties")
public class MiscMessageProperties {
@Id
private PropertiesKey propertiesKey;
}
