java - 如何解决Maven对MongoDB的依赖

Question

com.mongodb.MongoClient //is not exists

public class MonGoDemo {

    public static void main(String[] args) {
        //mongodb Connection Client.
        MongoClient mongoClient = new MongoClient();
    }
}

Answer 1

首先确保您有 dependency在你的 pom.xml 中:

<!-- https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver -->
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.8.0</version>
</dependency>

第二要使用类中的com.mongodb.MongoClient，您必须像这样导入它:

import com.mongodb.MongoClient;

public class MonGoDemo {
    public static void main(String[] args) {
        MongoClient mongoClient = new MongoClient();
    }
}
