Spring数据MongoDB身份验证错误

Question

我无法用spring-data-mongodb插入文档对象。我在我的spring-mvc项目中配置了MongoDB，像这样：

@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"; 
    } 

} 

我已经添加了存储库和文档。在我的控制器之一，我插入一个伪文档是这样的：

@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:/"; 
} 

当我输入相应的这种方法的URL，它需要几秒钟，给出了这样的错误：

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. 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 }}}] 

我不能透露问题。我有一个上面配置的用户，我能够以该用户的身份在mongo shell中编写和读取查询。但是，它通过春天失败。为什么？

难道你试试这个代码MongoConfiguration它可以帮助你，让我知道，如果它解决您的问题

@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); 
    } 

}
