java-Spring Boot设置MongoDB存储库

2019-10-26 21:21:19  阅读：320  来源： 互联网

标签：mongodb spring-boot spring-data spring java


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;
    }
}

然后我有我的文件课

@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

错误记录

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

如果不是,则为文件名输入错误.

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
