Question

我真的需要一些帮助，我经历了整整一天的搜索，但仍然找不到任何有用的东西。

注意：我的数据库有用户名和密码

这两个是我正在使用的依赖项。

<dependencies>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-mongodb</artifactId>
            <version>1.7.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>2.11.0</version>
        </dependency>
</dependencies>

这是我的xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<mongo:mongo-client  host="address" port="27017 credentials="username:password@databasename" />

</beans>

这是加载此xml的主要类：

    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.GenericXmlApplicationContext;
    import org.springframework.data.mongodb.core.MongoOperations;
    import org.springframework.data.mongodb.core.query.Criteria;
    import org.springframework.data.mongodb.core.query.Query;

    import model.user;
    //import org.springframework.context.support.GenericXmlApplicationContext;

public class App {

    public static void main(String[] args) {
        /*
        ApplicationContext ctx = new AnnotationConfigApplicationContext(appConfig.class);
        MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
*/

        ApplicationContext ctx = new GenericXmlApplicationContext("config.xml");
        MongoOperations mongoOperation = (MongoOperations)ctx.getBean("mongoTemplate");

        user user = new user();

        // save
        // mongoOperation.save(user);

        // now user object got the created id.
        System.out.println("1. user : " + user);

        // query to search user
        Query searchUserQuery = new Query(Criteria.where("age").is(26));
        mongoOperation.findOne(searchUserQuery, user.class);
    }

}

这是我收到的错误消息：

好的，最后我能够连接到数据库，我是使用MongoClient完成的。这是代码段：

MongoCredential credential = MongoCredential.createMongoCRCredential("username", "database", password);
MongoClient mongoClient = new MongoClient(new ServerAddress("address", 27017), Arrays.asList(credential));

    // get handle to "mydb"
    DB db = mongoClient.getDB("IODS");

    // get a list of the collections in this database and print them out
    Set<String> collectionNames = db.getCollectionNames();
    for (final String s : collectionNames) {
        System.out.println(s);
    }


    // get a collection object to work with
    DBCollection coll = db.getCollection("try_vishal");

如何通过spring将mongodb中的数据库链接起来
