Using Spring boot 1.5.6.RELEASE.
I have the following mongo document base class:
@Document(collection="validation_commercial")
public abstract class Tier {
@Id
private String id;
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
private Date created;
@Field("tran")
private Tran tran;
public Tier() {
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Date getCreated() {
return created;
}
public void setCreated(Date created) {
this.created = created;
}
public Tran getTran() {
return tran;
}
public void setTran(Tran tran) {
this.tran = tran;
}
}
which is then extended:
public class Tier1 extends Tier {
@Field("tier1")
private Tier1Programs tier1;
public Tier1() {
this.tier1 = new Tier1Programs();
}
public Tier1Programs getTier1() {
return tier1;
}
public void setTier1(Tier1Programs tier1) {
this.tier1 = tier1;
}
}
which in turn is extended:
public class Tier2 extends Tier1 {
@Field("tier2")
private Tier2Programs tier2;
public Tier2() {
this.tier2 = new Tier2Programs();
}
public Tier2Programs getTier2() {
return tier2;
}
public void setTier2(Tier2Programs tier2) {
this.tier2 = tier2;
}
}
There is a Tier1 Supervisor (Spring Boot Application) that uses the Tier1 class within the MongoRepository interface:
public interface Tier1Repository extends MongoRepository<Tier1,String>{}
for retrieving and saving - no issue.
I then have a Tier2 Supervisor (Spring Boot Application) that uses a Tier1 Repository (for retrieving the Tier1 document and a Tier2 Repository for saving the Tier2 document:
@Repository("tier1Repository")
public interface Tier1Repository extends MongoRepository<Tier1,String>{}
@Repository("tier2Repository")
public interface Tier2Repository extends MongoRepository<Tier2,String>{}
My service is:
@Service
public class TierService {
@Qualifier("tier1Repository")
@Autowired
private final Tier1Repository tier1Repository;
@Qualifier("tier2Repository")
@Autowired
private final Tier2Repository tier2Repository;
public TierService(@Qualifier("tier1Repository") Tier1Repository tier1Repository, @Qualifier("tier2Repository") Tier2Repository tier2Repository) {
this.tier1Repository = tier1Repository;
this.tier2Repository = tier2Repository;
}
public Tier1 findOne(String id) {
return tier1Repository.findOne(id);
}
public void SaveTier(Tier2 tier) {
tier2Repository.save(tier);
}
public Tier1Repository getTier1Repository() {
return tier1Repository;
}
public Tier2Repository getTier2Repository() {
return tier2Repository;
}
}
and finally the app:
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class, JdbcTemplateAutoConfiguration.class})
@Configuration
@ComponentScan(basePackages = {"com.k12commercial.tier2supervisor"})
@ImportResource("classpath:application-context.xml")
public class Application implements CommandLineRunner {
@Autowired
private IReceiver raBidNetPriceReceiver;
@Autowired
private UdyDataSourceFactory udyDSRegistry;
public static void main(String[] args) throws InterruptedException {
try {
SpringApplication.run(Application.class, args);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void run(String... args) throws Exception {
raBidNetPriceReceiver.processTierMessages();
exit(0);
}
}
When I run the Tier2 Supervisor from the command line I get the following error:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'tierService' defined in URL
[jar:file:/opt/java-commandline/tier2supervisor-1.0.jar!/BOOT-INF/classes!/com/k12commercial/tier2supervisor/service/TierService.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tier2Repository': Invocation of init method failed; nested exception is org.springframework.data.mapping.model.MappingException: Ambiguous field mapping detected! Both private final java.lang.reflect.Type org.springframework.data.util.TypeDiscoverer.type and private final java.lang.Class org.springframework.data.util.ClassTypeInformation.type map to the same field name type! Disambiguate using @Field annotation!
I am not sure if the issue is Tier2 extending Tier1 (did try putting @Document tag above Tier1 and Tier2 with no change). I think I have marked the relevant fields so don't understand the need to disambiguate. I thought the issue was having 2 repositories (Spring Boot not knowing which one to DI) so removed the Tier1Repository - didn't work. Tried better qualifying the repositories but still got the same error. I made Tier1 and Tier2 @Transient and that got rid of the message but also removed the tier1 section in the mongo document - so wrong correction.
Thinking it is an annotation fix but not seeing it...
Please advise - thank you.
