通过Spring Boot应用访问mongodb时出现身份验证错误

spring-boot

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={}}

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,

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=192.168.1.90
spring.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,
