Spring-data Mongodb JUnit错误

Question

我正在做一个spring MVC项目，它使用了Spring data和Mongodb。我只是创建了实体并进行了配置。然后，一旦使用JUnit进行测试，我就得到了一个无法修复的错误。有谁能帮我这个忙吗？下面是我的spring配置文件：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.0.xsd
      http://www.springframework.org/schema/data/mongo
      http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
      http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<mongo:mongo host="127.0.0.1" port="27017" />
<mongo:db-factory dbname="AgenceAviationDB" />

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>

下面是我的maven依赖项：

    spring-core 4.2.1.RELEASE
    mongo-java-driver 2.12.1
    spring-data-mongodb 1.4.2.RELEASE
    spring-context 4.2.1.RELEASE
    junit 4.7

下面是我的一个实体：

package com.pfa.agenceDaviation.entities;
import java.io.Serializable;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document
public class Passager implements Serializable{
@Id
private String id;
private String nomP;
private String adresseP;
private String nTelephoneP;
//setters getters and constructors

这是我的测试类：

package com.pfa.agenceDaviation;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; 
import org.springframework.context.support.GenericXmlApplicationContext;
import org.springframework.data.mongodb.core.MongoOperations;
public class testDAO {
@Before
public void setUp() throws Exception {
}

@Test
public void test() {
    try {
        ApplicationContext ctx = new GenericXmlApplicationContext("ApplicationContext.xml");
           MongoOperations mongoOperation = (MongoOperations)ctx.getBean("mongoTemplate");  
            assertTrue(true);

    } 
    catch (Exception e) {
    assertTrue(e.getMessage(),false);
    }
    }
    }

这就是我得到的错误：

有谁能帮我这个忙吗？非常感谢！

spring data运行mvn dependency:tree

• Pay注意您的-
• -mongodb依赖项

您会注意到spring-data-mongodb使用的是spring版本-4.2.1。这里是proof - http://mvnrepository.com/artifact/org.springframework.data/spring-data-mongodb/1.4.2.RELEASE

因此，可能的解决方案-将spring依赖更新到4.2.1

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>

下一步，您需要检查您是否真的需要存储spring-data-mongodb中真正需要的spring-core和spring-context.If --只需从spring中排除这些依赖项即可
