Question

我有一个使用Spring Data MongoDB和MongoDB驱动程序的简单java应用程序。我只是将一个新用户添加到MongoDB集合中。但是当MongoOperations的save方法执行时，它会产生NoSuchMethodError。

这是我的pom.xml的依赖部分：

这是我的MongoConfig类

    import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.MongoDbFactory;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.SimpleMongoDbFactory;

import com.mongodb.MongoClient;

@Configuration
public class MongoConfig {

    public @Bean
    MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(new MongoClient(), "monitor");
    }

    public @Bean
    MongoTemplate mongoTemplate() throws Exception {

        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());

        return mongoTemplate;

    }

}

这是我的DBOperations类，我在执行save（）方法时遇到错误：

import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;

import com.bng.monitor.config.MongoConfig;
import com.bng.monitor.model.User;
//import org.springframework.context.support.GenericXmlApplicationContext;

public class DbOperations {

    public static void main(String[] args) {

    // For XML
    //ApplicationContext ctx = new GenericXmlApplicationContext("SpringConfig.xml");

    // For Annotation
    ApplicationContext ctx =
             new AnnotationConfigApplicationContext(MongoConfig.class);
    MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");

    User user = new User("kv", "password123");

    // 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("username").is("kv"));

    // find the saved user again.
    User savedUser = mongoOperation.findOne(searchUserQuery, User.class);
    System.out.println("2. find - savedUser : " + savedUser);

    // update password
    mongoOperation.updateFirst(searchUserQuery,
                         Update.update("password", "new password"),User.class);

    // find the updated user object
    User updatedUser = mongoOperation.findOne(searchUserQuery, User.class);

    System.out.println("3. updatedUser : " + updatedUser);

    // delete
    mongoOperation.remove(searchUserQuery, User.class);

    // List, it should be empty now.
    List<User> listUser = mongoOperation.findAll(User.class);
    System.out.println("4. Number of user = " + listUser.size());

    }

}

这是我的模特课：

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "users")
public class User {

    @Id
    private String id;

    private String username;

    private String password;

    public User(String username, String password){
        super();
        this.username = username;
        this.password = password;
    }

    public void setId(String id){
        this.id = id;
    }

    public String getId(){
        return this.id;
    }

    public void setUsername(String username){
        this.username = username;
    }

    public String getUsername(){
        return this.username;
    }

    public void sePassword(String password){
        this.password = password;
    }

    public String gePassword(){
        return this.password;
    }
}

这是异常堆栈跟踪：

任何人都可以帮忙，我在做什么错？

您的问题与您使用spring-data-mongodb 1.9.4.RELEASE Spring 4.2.8.RELEASE时使用4.1.5.RELEASE Spring这样的事实有关如果版本为spring-data-mongodb，则只需将Spring的版本降级为1.8.x，因为它取决于4.1.x {{1}}（您的目标版本）。
