关于创建springboot项目,test测试类引包异常报错求解?

通过快速初始化工具创建springboot项目后,Test测试类提示导入包异常。eclipse和idea皆是如此。
图片说明

idea的的问题可以通过手动导入idea安装目录lib文件夹下的junit-4.12.jar解决问题。但是eclipse受到导入junit只能解决org.junit.Test;和org.junit.runner.RunWith;的问题。至于org.springframework.boot.test.context.SpringBootTest;的@SpringBootTest仍然提示无效。求解?

2个回答

让idea自动从网络上下载缺失的jar即可,可能是兼容问题。

huwao 不行的自己上官网找个合适版本的jar应该能解决,要还是不行就是IDE的问题了。重装一下IDE或者更新一下版本。
一年多之前 回复
<properties>
        <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
    </properties>
properties中加入这个。然后再重新导入测试的jar

linux部署springboot项目的问题
