错误导入依赖关系

我来自一个红宝石编程背景，我已经开始学习java。我绝对爱上它。现在我正在尝试运行示例aws iot java sdk项目，但我不断收到此错误。错误导入依赖关系

import com.fasterxml.jackson.databind.DeserializationFeature; 
import com.fasterxml.jackson.databind.ObjectMapper; 

The import com.fasterxml.jackson.databind.DeserializationFeature cannot be resolved

当我看着maven的依赖性文件夹内，并导航到com.fasterxml.jackson.databind我没有发现任何类DeserializationFeature以及ObjectMapper

任何想法？

显示你的pom.XML请 – Jens

也许这个依赖jar太旧... – passion

@Jens，已更新。 –

您需要添加依赖杰克逊，数据绑定

<dependency> 
     <groupId>com.fasterxml.jackson.core</groupId> 
     <artifactId>jackson-databind</artifactId> 
     <version>2.8.0</version> 
    </dependency>

嘿，感谢它现在的工作 –

它应该在杰克逊数据绑定-2.8.0.jar – ravthiru

亚是它。我假设它将在其单独的文件中，但事实证明它是数据绑定类中的一种方法。再次感谢队友 –

可以确认罐子的版本.... jackson.databind.jar其一部分...你可能需要正确的版本
