所以我知道还有其他类似的问题,但我认为我的问题无法解决。
希望你们其中一个人能看出我做错了什么。
当我去localhost //:8080时,我得到“whitelabel error ....”
我的pom.xml看起来像这样:

我的应用程序类看起来像这样:
package com.example.mavenproject1;
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
/**
*
* @author Steffen
*/
@RestController
@EnableAutoConfiguration
@ComponentScan
public class Application {
//Run a function here which dives into the mongoDB and returns the info?
@RequestMapping("/")
String home() {
DBPopulator dbp = new DBPopulator();
dbp.saveNew();
// return dbp.getFil();
return "Hey wassup";
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
DBPopulator:
package com.example.mavenproject1;
import java.util.Date;
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 org.springframework.context.support.GenericXmlApplicationContext;
/**
*
* @author Steffen
*/
public class DBPopulator {
ApplicationContext ctx = new AnnotationConfigApplicationContext(ConnectToDB.class);
MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
private int vers = 0;
public void saveNew() {
Fil f = new Fil("fil" + vers + "", new MetaData(new Date(), new Date(), 5));
vers++;
mongoOperation.save(f);
};
public String getFil(){
// query to search user
Query searchQuery = new Query(Criteria.where("filNavn").is("fil1"));
Fil savedF = mongoOperation.findOne(searchQuery, Fil.class);
List<Fil> listFiler = mongoOperation.findAll(Fil.class);
System.out.println("Here is my file: " + savedF);
return "File: " + savedF;
}
}
现在我的应用程序“正常工作”,因为它将新的“Fil”保存到我的mongoDB中。我想在Application类的“Home”函数中返回它们,但到目前为止我除了“whitelabel error”之外什么也得不到...
提前致谢!
**修改
来自localhost //:8080的完整错误是:
Whitelabel错误页面
此应用程序没有/ error的显式映射,因此您将此视为回退。 Mon Aug 07 16:39:18 CEST 2017 出现意外错误(type = Internal Server Error,status = 500)。 COM / mongodb的/ BulkWriteException
答案 0 :(得分:2)
看起来它正在寻找可从2.12 mongo驱动程序版本获得的BulkWriteException。
解决方案1
至少升级到
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.12.0</version>
</dependency>
解决方案2(更好)
删除
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.11.0</version>
</dependency>
并保持
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.10.6.RELEASE</version>
</dependency>
引入正确的依赖关系,即2.4.x mongo驱动程序。
解决方案3(最佳)
删除
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.11.0</version>
</dependency>
和
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.10.6.RELEASE</version>
</dependency>
添加
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
拉出兼容的spring mongo和mongo依赖,这是2.4.x mongo驱动程序。
