org.springframework.web.bind.annotation.ResponseStatus和org.springframework.http.HttpStatus不存在
提问于 2019-04-25 15:23:51
我正在开发一个CRUD Web应用程序，使用以下说明：
https://www.javaguides.net/2019/02/spring-boot-2-angular-7-crud-example-tutorial.html作为指南说，在编译文件: ResourceNotFoundException.java时，我使用了spring框架作为后端。
它给了我这个错误：
C:\Users\Roberto\Desktop\ springboot2-jpa-crud-example\src\test\java\net\guides\springboot2\springboot2jpacrudexample\exception>javac ResourceNotFoundException.java
ResourceNotFoundException.java:2: error: package org.springframework does not exist
import org.springframework.http;
^
ResourceNotFoundException.java:3: error: package org.springframework.http does not exist
import org.springframework.http.HttpStatus;
^
ResourceNotFoundException.java:4: error: package org.springframework.web.bind does not exist
import org.springframework.web.bind.annotation;
^
ResourceNotFoundException.java:5: error: package org.springframework.web.bind.annotation does not exist
import org.springframework.web.bind.annotation.ResponseStatus;
^
ResourceNotFoundException.java:7: error: cannot find symbol
@ResponseStatus(value = HttpStatus.NOT_FOUND)
^
symbol: class ResponseStatus
5 errors我在web上注意到，这个问题可以由maven版本o npm版本(npm -version 6.9.0 \ mvn -v Apache Maven 3.6.1)来解决，并且可以通过向pom.xlm文件添加一些依赖项来解决问题，我在这里发布了pom.xlm文件：

如果有人能帮我，那就太棒了
__________________________UPDATE_______________________
正如下面的评论所示，我只是尝试将此代码添加到我的pom.xlm文件中
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.1.6.RELEASE</version>
但是在编译之后，它没有工作
