问题
In here I have configured two databases in mongodb. As described in this tutorial (link). So basically I override the MongoDataAutoConfiguration and MongoProperties implementations.
The property yml file :
spring:
autoconfigure:
exclude:
org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
mongodb:
primary:
host: 127.0.0.1
port: 27017
database: db_admin_crm
secondary:
host: 127.0.0.1
port: 27017
database: lead_forms
MultipleMongoProperties class :
@Data
@ConfigurationProperties(prefix = "mongodb")
public class MultipleMongoProperties {
private MongoProperties primary = new MongoProperties();
private MongoProperties secondary = new MongoProperties();
//getters and setters
}
MultipleMongoConfig class :
@Configuration
@RequiredArgsConstructor
@EnableConfigurationProperties(MultipleMongoProperties.class)
public class MultipleMongoConfig {
@Autowired
private final MultipleMongoProperties mongoProperties;
public MultipleMongoConfig() {
mongoProperties = null;
}
@Primary
@Bean(name = "primaryMongoTemplate")
public MongoTemplate primaryMongoTemplate() throws Exception {
return new MongoTemplate(primaryFactory(this.mongoProperties.getPrimary()));
}
@Bean(name = "secondaryMongoTemplate")
public MongoTemplate secondaryMongoTemplate() throws Exception {
return new MongoTemplate(secondaryFactory(this.mongoProperties.getSecondary()));
}
@Bean
@Primary
public MongoDbFactory primaryFactory(final MongoProperties mongo) throws Exception {
return new SimpleMongoDbFactory(new MongoClient(mongo.getHost(), mongo.getPort()),
mongo.getDatabase());
}
@Bean
public MongoDbFactory secondaryFactory(final MongoProperties mongo) throws Exception {
return new SimpleMongoDbFactory(new MongoClient(mongo.getHost(), mongo.getPort()),
mongo.getDatabase());
}
}
PrimaryMongoConfig :
@Configuration
@EnableMongoRepositories(basePackages = "io.crm.service.repositories",
mongoTemplateRef = "primaryMongoTemplate")
public class PrimaryMongoConfig{
}
SecondaryMongoConfig :
@Configuration
@EnableMongoRepositories(basePackages = "io.crm.service.repositories.report.repositories",
mongoTemplateRef = "secondaryMongoTemplate")
public class SecondaryMongoConfig {
}
The Repository class :
@RepositoryRestResource(collectionResourceRel = "users",path = "users",excerptProjection = UserProjection.class)
public interface UserRepository extends MongoRepository<User, String> {
}
User model class :
@Id
private String id;
private String email;
private String name;
private String businessName;
private String phone;
private String address;
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
private Date createdTime;
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
private Date updatedTime;
@Field("bookletSignUps")
@DBRef
private List<BookletSignUp> bookletSignUps;
@Field("eventSignUps")
@DBRef
private List<EventSignUp> eventSignUps;
@Field("infoSignUps")
@DBRef
private List<InfoSignUp> infoSignUps;
@Field("webinarSignUps")
@DBRef
private List<WebinarSignUp> webinarSignUps;
The projection :
@Projection(name = "userExcerpt", types = User.class)
public interface UserProjection {
String getId();
String getName();
String getEmail();
String getBusinessName();
String getPhone();
String getAddress();
Date getCreatedTime();
Date getUpdatedTime();
List<BookletSignUp> getBookletSignUps();
List<EventSignUp> getEventSignUps();
List<InfoSignUp> getInfoSignUps();
List<WebinarSignUp> getWebinarSignUps();
}
But when im trying to do a GET request to the REST endpoint http://localhost:9090/users/ im getting java.lang.IllegalArgumentException: Couldn't find PersistentEntity for type class io.crm.service.models.User! exception here. What could be gone wrong here? Ideas will be very much appreciated. Thanks in advance.
