问题

我无法提供代码的翻译，但以下是您提供的英文文本的中文翻译：

"我一直无法导入以下库以用于处理一些错误。我一直在互联网上寻找有关这个问题的信息，但没有成功。是不是我需要下载一个特定的.jar文件？如果是这样，我将感谢您告诉我如何做。我对这个网络和Spring的东西还不太了解。"

提前感谢您的帮助。

I haven not being able to import the following library to use it for handling some error. I have been looking up on internet about this problem but cannot succeed. Is it that i have to download an specific .jar? if so, I would appreciate the help to know how to do it. I am pretty new into this web and spring stuff.

你正在寻找的JAR文件可以从Maven仓库这里获取。

如果您使用Maven进行依赖管理，只需将以下内容添加到您的pom.xml文件中：

  1. <dependency>
  2.     <groupId>org.springframework.data</groupId>
  3.     <artifactId>spring-data-rest-webmvc</artifactId>
  4.     <version>3.3.3.RELEASE</version>
  5. </dependency>
英文:

The jar you looking for is available from maven repo here .

If you use maven for dependency management just add this to your pom.xml

  1.     &lt;dependency&gt;
  2. &lt;groupId&gt;org.springframework.data&lt;/groupId&gt;
  3. &lt;artifactId&gt;spring-data-rest-webmvc&lt;/artifactId&gt;
  4. &lt;version&gt;3.3.3.RELEASE&lt;/version&gt; 
  5. &lt;/dependency&gt;
