通过 Spring Boot 应用程序访问 mongodb 时的身份验证错误

我发现了问题.为了这个帖子的完整性，我将分享答案，包括代码.

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、主机和凭据都在应用程序中.属性文件:

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);
        }
    }
}

我希望这个解释能帮助其他无法理解的人，比如我自己.

谢谢
