我正在尝试在我的spring-boot rest应用程序中设置MongoDB存储库以进行CRUD操作.这是我到目前为止所拥有的
我的applicaiton.yml文件
server:
data:
mongodb: localhost
port: 27017
database: dbname
我的DbConfiguration类别
@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;
}
}
@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
}
我的存储库类
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();
}
最后是服务等级
@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();
}
}
启动应用程序时,出现错误,无法自动连接bookRepository …这是完全异常

解决方法:
如错误所暗示：
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]
您必须设置应用程序要使用的数据库名称.或者,如果在这里设置：
My applicaiton.yml file
既然您已经在使用Spring Boot,为什么不对mongodb使用spring属性呢？
对于Ver 3.0驱动程序
spring.data.mongodb.uri=mongodb://user:secret@localhost:12345
对于2.x版驱动程序
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
更多信息在这里http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-nosql.html
