通过Spring Boot应用访问mongodb时出现身份验证错误
我从Java Spring
Boot应用程序连接到远程mongodb时遇到一些麻烦。MongoDB服务器没有设置防火墙,我可以从另一台计算机远程连接到mongo。我有一个包含集合和用户设置的数据库。当我尝试使用用户凭据从Java应用程序连接到数据库时,出现异常:
com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName='sokrates', source='homeControl', password=<hidden>, mechanismProperties={}}at com.mongodb.connection.SaslAuthenticator.authenticate(SaslAuthenticator.java:61) ~[mongodb-driver-core-3.2.2.jar:na]

当我使用相同的代码以相同的设置,数据库,集合和用户连接到本地MongoDB时,一切正常。
在mongo安装上设置管理员用户时遇到了一些麻烦。同样,本地mongo在OSX上运行,而生产mongo(无法通过身份验证)在Ubuntu Server
16.04上运行。我已经研究了其他MongoDB身份验证线程两天了,但是没有人可以为我解决这个问题。任何与此有关的帮助表示赞赏:-)
谢谢,

回答:
我发现了问题。为了确保该线程的完整性,我将分享答案,包括代码。问题是我错误地使用了应用程序属性spring.data.mongodb.uri:它在URI中没有用户名和密码,因为我错误地认为spring.data.mongodb.username和spring.data.mongodb.password涵盖了。因此,要么将uri与用户名和密码一起使用,要么显式使用主机和数据库(也许还有端口)spring属性。这是代码。它将在支持mongoDB的spring
boot应用程序中运行(使用initializr或IntelliJ创建该项目)。我有一个模型:
package net.IndyStef.model;import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document(collection = "person")
public class Person {
@Id
private String id;
private String name;
private Integer age;
public Person() {
}
public Person(String id) {
this.id = id;
}
public Person(String id, String name, Integer age) {
this.id = id;
this.name = name;
this.age = age;
}
... getters/setters omitted for breverity ...
}
通过存储库读取和写入数据:
package net.IndyStef.repository;import net.okrongli.model.Person;
import org.springframework.data.mongodb.repository.MongoRepository;
/**
* Created by IndyStef on 23/08/16.
*/
public interface PersonRepository extends MongoRepository<Person, String> {
}
数据库名称,主机和凭据位于application.properties文件中:
spring.data.mongodb.host=192.168.1.90spring.data.mongodb.database=people
spring.data.mongodb.username=user
spring.data.mongodb.password=password
#spring.data.mongodb.uri=mongodb://192.168.1.90/people
重要的是不要将uri与数据库和用户名混合使用。如果使用uri,则需要包含用户名和密码,如下所示:
spring.data.mongodb.uri=mongodb://user:password@192.168.1.90/people
为了测试这一点,我使用了一个简单的Spring命令行运行程序:
package net.IndyStef;import net.IndyStef.model.Person;
import net.IndyStef.repository.PersonRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import java.util.List;
@SpringBootApplication
public class MongoDbTestApplication implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(MongoDbTestApplication.class, args);
}
@Autowired
private PersonRepository repository;
@Override
public void run(String... args) {
repository.save(new Person("peter.pan", "Peter Pan", 865));
List<Person> people = repository.findAll();
for (Person person: people) {
System.out.println(person);
}
}
}
我希望这种解释能帮助无法理解的其他人,例如我几天。
谢谢,
