使用 Spring 后端问题插入 MongoDB？答案

【问题标题】：Insert in MongoDB with Spring backend issue?使用 Spring 后端问题插入 MongoDB？

【问题描述】：

我曾经将数据插入到 MongoDB 数据库中，但遇到了一些问题；这是我的main.java

@SpringBootApplication
public class Application {
    public static final String DB_NAME = "test";
    public static final String USERS_COLLECTION = "users";
    public static final String MONGO_HOST = "localhost";
    public static final int MONGO_PORT = 27017;

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
        try {
            MongoClient mongo = new MongoClient(MONGO_HOST, MONGO_PORT);
            MongoOperations mongoOps = new MongoTemplate(mongo, DB_NAME);
            Test2 p = new Test2("jon");
            mongoOps.insert(p, USERS_COLLECTION);
            mongo.close();

        } catch (UnknownHostException e) {
            e.printStackTrace();
        }

    }}

这是我的实体：

@Document
public class Test2 extends DomainBase {

    /**
     * 
     */
    private static final long serialVersionUID = -1866079511424097005L;

    private Long Id;
    private String mail;

    public Test2() {
        super();
    }

    public Test2(String mail) {
        this.setMail(mail);
    }

    @Id
    @Field("id")
    public Long getId() {
        return Id;
    }

    public void setId(Long id) {
        Id = id;
    }

    public String getMail() {
        return mail;
    }

    public void setMail(String mail) {
        this.mail = mail;
    }
}

这是我的存储库：

public interface Test2Repo extends MongoRepository<Test2, Long> {

}

我认为这部分做得很好，但它不断向我显示以下相同的错误：

你能帮帮我吗？

【问题讨论】：

您可以尝试将 MongoRepository 的类型从 Long 更改为 String 吗？并使用@Id private String id；在课堂上？

标签： mongodb maven spring-boot

【解决方案1】：

毕竟我不得不删除pom.xml 中的spring-data-mongodb 依赖版本来修复它，因为它显示了一个警告；所以它变成了：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
</dependency>
