Spring Boot Einrichtung MongoDB Repository

Question

Ich versuche, MongoDB Repository für CRUD-Betrieb in meiner Spring-Boot-Rest-App einrichten. Hier ist, was ich bisher

Meine applicaiton.yml Datei

server: 
    data: 
    mongodb: localhost 
    port: 27017 
    database: dbname 

Meine DbConfiguration Klasse

@Configuration 
@EnableMongoRepositories("com.package.path.to.repository") 
@Import(value = MongoAutoConfiguration.class) 
public class DbConfiguration extends AbstractMongoConfiguration { 

    private final Logger log = LoggerFactory.getLogger(DbConfiguration.class); 

    @Autowired 
    private Mongo mongo; 

    @Autowired 
    private MongoProperties mongoProperties; 

    @Bean 
    public ValidatingMongoEventListener validatingMongoEventListener() { 
     return new ValidatingMongoEventListener(validator()); 
    } 

    @Bean 
    public LocalValidatorFactoryBean validator() { 
     return new LocalValidatorFactoryBean(); 
    } 

    @Override 
    protected String getDatabaseName() { 
     return mongoProperties.getDatabase(); 
    } 

    @Override 
    public Mongo mongo() throws Exception { 
     return mongo; 
    } 
} 

Dann habe ich meine Document Klasse

@Document(collection = "T_BOOK") 
public class Book implements Serializable { 
    private static final long serialVersionUID = 1L; 

    @Id 
    private String id; 

    @NotNull 
    @Size(min = 5, max = 100) 
    @Field("name") 
    private String name; 

    @NotNull 
    @Field("publisher") 
    private String publisher; 
    //more methods and setters/getters 
} 

Meine Repository Klasse

package com.package.path.to.repository; 

import org.springframework.data.mongodb.repository.MongoRepository; 

import java.util.List; 

public interface BookRepository extends MongoRepository<Book, String> { 
    Book findOneById(String id); 

    List<Book> findAll(); 

    void delete(Book b); 

    void deleteAll(); 
} 

und schließlich die service Klasse

@Service 
public class BookService { 
    @Autowired 
    private BookRepository bookRepository; 

    public List<Book> findAll() { 
     return bookRepository.findAll(); 
    } 

    public Book findById(String id) { 
     return bookRepository.findOneById(id); 
    } 

    public Book save(Book book) { 
     return bookRepository.save(book); 
    } 

    public void delete(Book book) { 
     bookRepository.delete(book); 
    } 

    public void deleteAll() { 
     bookRepository.deleteAll(); 
    } 

} 

Wenn ich die Anwendung zu starten, ich einen Fehler, dass nicht in der Lage zu autowire bookRepository ... hier ist voll Ausnahme

Fehlerprotokoll

Answer 1

Wie der Fehler impliziert:

Caused by: java.lang.IllegalArgumentException: Database name must not be empty 
at org.springframework.util.Assert.hasText(Assert.java:168) ~[spring-core-4.3.2.RELEASE.jar:4.3.2.RELEASE] 

Sie müssen den Datenbanknamen festlegen, der von Ihrer Anwendung verwendet werden soll. Oder, wenn es hier ein:

My applicaiton.yml file 

Wenn nicht, es ist ein Tippfehler-Fehler auf den Dateinamen.

Da Sie bereits Spring-Boot verwenden, warum nicht die Federeigenschaften für Mongodb verwenden?

für ver 3.0-Treiber

spring.data.mongodb.uri=mongodb://user:secret@localhost:12345 

für ver-2.x-Treiber

spring.data.mongodb.host=localhost 
spring.data.mongodb.port=27017 

Mehr Infos hier http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-nosql.html

Answer 2

ich den Namen der Datenbank in application.yml Datei wie unten

definiert haben

spring: 
    profiles: 
     active: prod 
    devtools: 
     restart: 
      enabled: false 
     livereload: 
      enabled: false 
    data: 
     mongodb: 
      host: localhost 
      port: 27017 
      database: test 

aber immer noch bekomme ich diesen Fehler.

Irgendwelche Hinweise bitte?
