我需要在mongoDB中轻松插入并检查新的寄存器。

这是我的pom：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>2.1.1.RELEASE</version><!--$NO-MVN-MAN-VER$ -->
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>
    <dependency>
        <groupId>de.flapdoodle.embed</groupId>
        <artifactId>de.flapdoodle.embed.mongo</artifactId>
        <scope>test</scope>
    </dependency>

</dependencies>

这是我的test.java：

import static org.assertj.core.api.Assertions.assertThat;

import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.data.mongo.DataMongoTest;
import org.springframework.data.mongodb.core.MongoTemplate;

import com.batch.DesarrolloBatch.model.Documento;
import com.mongodb.BasicDBObjectBuilder;
import com.mongodb.DBObject;

@DataMongoTest
public class TestApplicationConfiguration {


            @Test
            public void test(@Autowired MongoTemplate mongoTemplate) {
                // given
                DBObject objectToSave = BasicDBObjectBuilder.start()
                    .add("_id", "999999999999")
                    .get();

                // when
                mongoTemplate.save(objectToSave, "collection");

                List<Documento> list =  mongoTemplate.findAll(Documento.class, "collection");

               System.out.println("size " + list.size());

                // then
                assertThat(mongoTemplate.findAll(Documento.class, "collection")).extracting("_id")
                    .containsOnly("999999999999");
            }
}

我正在尝试插入属性_id值= 99999999的新Documento

但是此代码失败，因此，我尝试查看列表的大小以了解是否插入成功...

我收到此错误：

我是monitdb的Junit新手，我只想使用mongoDB嵌入并插入并检查我的bbdd ....谢谢...

您忘记了在类级别的注释：@ExtendWith（SpringExtension.class）

@DataMongoTest
@ExtendWith(SpringExtension.class)
public class TestApplicationConfiguration {

        @Test
        public void test(@Autowired MongoTemplate mongoTemplate) {
            // your test code
        } 
}

请仔细阅读本教程。

这是GitHub Repo的链接，您可以在其中找到pom.xml和所有源代码：
