Java Spring数据MongoDB身份验证错误

我无法插入带有spring data mongodb的文档对象。我在spring mvc项目中配置了MongoDB，如下所示：

@Configuration
@EnableMongoRepositories(basePackages = { "com.example.store.repository" })
public class MongoConfiguration extends AbstractMongoConfiguration {

    @Bean
    public Mongo mongo() throws UnknownHostException {
        ServerAddress serverAddress = new ServerAddress("localhost", 27017);
        MongoCredential credential = MongoCredential.createMongoCRCredential("username", "store", "password".toCharArray());
        MongoClientOptions options = MongoClientOptions.builder().connectionsPerHost(4).socketKeepAlive(true).build();
        Mongo mongo = new MongoClient(serverAddress, Arrays.asList(credential), options);
        return mongo;
    }

    @Bean(name = "MongoTemplate")
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongo(), "store");
    }

    @Override
    protected String getDatabaseName() {
        return "store";
    }

} 

@RequestMapping(value="/add", method=RequestMethod.GET)
public String addProduct() {
    Product product = new Product();
    product.setName("New Product");
    product.setDescription("Product Description");
    product.setUnitPrice(19.99);

    productRepository.insert(product);

    return "redirect:/";
}

我还添加了存储库和文档。在我的一个控制器中，我插入一个伪文档，如下所示：

@Configuration
@EnableMongoRepositories(basePackages = { "com.example.store.repository" })
public class MongoConfiguration extends AbstractMongoConfiguration {

    @Bean
    public Mongo mongo() throws UnknownHostException {
        ServerAddress serverAddress = new ServerAddress("localhost", 27017);
        MongoCredential credential = MongoCredential.createMongoCRCredential("username", "store", "password".toCharArray());
        MongoClientOptions options = MongoClientOptions.builder().connectionsPerHost(4).socketKeepAlive(true).build();
        Mongo mongo = new MongoClient(serverAddress, Arrays.asList(credential), options);
        return mongo;
    }

    @Bean(name = "MongoTemplate")
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongo(), "store");
    }

    @Override
    protected String getDatabaseName() {
        return "store";
    }

} 

@RequestMapping(value="/add", method=RequestMethod.GET)
public String addProduct() {
    Product product = new Product();
    product.setName("New Product");
    product.setDescription("Product Description");
    product.setUnitPrice(19.99);

    productRepository.insert(product);

    return "redirect:/";
}

当我输入此方法对应的url时，需要几秒钟的时间，并出现以下错误：

 Request processing failed; nested exception is org.springframework.dao.DataAccessResourceFailureException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector. Client view of cluster state is {type=UNKNOWN, servers=[{address=localhost:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSecurityException: Exception authenticating}, caused by {com.mongodb.MongoCommandException: Command failed with error 18: 'auth failed' on server localhost:27017. The full response is { "ok" : 0.0, "errmsg" : "auth failed", "code" : 18 }}}]; nested exception is com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector.

我不能透露这个问题。我在上面配置了一个用户，我能够以该用户的身份在MongoShell中执行写和读查询。然而，它在春天失败了。为什么？

您可以尝试一下这段代码，因为MongoConfiguration它可能会帮助您，并让我知道它是否解决了您的问题

@Configuration
@EnableMongoRepositories(basePackages = { "com.example.store.repository" })
public class MongoConfiguration extends AbstractMongoConfiguration {

  @Bean
  public Mongo mongo() throws UnknownHostException {
    return mongoClient();
  }

  @Bean
  public MongoDbFactory mongoDbFactory() {
    return new SimpleMongoDbFactory(mongoClient(), getDatabaseName());
  }

  @Bean
  public MongoTemplate mongoTemplate() {
    return new MongoTemplate(mongoDbFactory(), null);
  }

  @Override
  protected String getDatabaseName() {
    return "store";
  }

  @Bean
  public MongoClient mongoClient() {    
    List<MongoCredential> credentialsList = new ArrayList<MongoCredential>();
    credentialsList.add(MongoCredential.createCredential("username", getDatabaseName(), "password".toCharArray());
    ServerAddress primary = new ServerAddress("localhost", 27017);
    MongoClientOptions mongoClientOptions = MongoClientOptions.builder().connectionsPerHost(4).socketKeepAlive(true).build();
    return new MongoClient(Arrays.aslist(primary), credentialsList, mongoClientOptions); 
  }

}

@配置
@EnableMongorPositories（basePackages={“com.example.store.repository”}）
公共类MongoConfiguration扩展了AbstractMongoConfiguration{
@豆子
public Mongo Mongo（）抛出UnknownHostException{
返回mongoClient（）；
}
@豆子
公共MongoDbFactory MongoDbFactory（）{
返回新的SimpleMongoDbFactory（mongoClient（），getDatabaseName（））；
}
@豆子
公共MongoTemplate MongoTemplate（）{
返回新的MongoTemplate（mongoDbFactory（），null）；
}
@凌驾
受保护的字符串getDatabaseName（）{
返回“存储”；
}
@豆子
公共MongoClient MongoClient（）{
List-credentialsList=new-ArrayList（）；
credentialsList.add（MongoCredential.createCredential（“username”，getDatabaseName（），“password.toCharray（））；
ServerAddress primary=新服务器地址（“本地主机”，27017）；
MongoClientOptions MongoClientOptions=MongoClientOptions.builder（）.connectionsPerHost（4.socketKeepAlive（true.build））；
返回新的MongoClient（Arrays.aslist（primary）、credentialsList、MongoClient）；
}
}

上面的配置在您的上下文中创建了多个类型为

MongoTemplate

的bean。声明为

@bean（name=“MongoTemplate”）的bean

将不会在存储库中使用。虽然这不会导致您遇到的错误…因此，请尝试删除手动声明的bean，除非它与代码中的某个

@限定符一起使用，然后再试一次。您有没有复制错误的小样本可以告诉我？哪个MongoDB服务器，m您使用的是ongo java client和Spring Data MongoDB版本吗？@ChristophStrobl事实上，先生，我不清楚到底发生了什么。我试图通过使用本文来实现它：。我让mongodb3在同一台机器上运行。mongo java驱动程序：3.1.0。
