java - import org.springframework.test.context.junit4.SpringRunner无法解析

Question

我正试图从现在开始解决这个问题。但我仍然没有解决它。我刚刚从 spring.io 下载了一个 spring 项目，并将其作为 Maven 项目导入到 Eclipse IDE。之后我得到这个上面提到的错误。

import org.springframework.test.context.junit4无法解析

我在下面附上了我的代码。连同完整的 pom.xml 内容。

package com.Ticket.Booking.TicketBooking;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;//I got the error in this line

@RunWith(SpringRunner.class)//Also in this line too.
@SpringBootTest
public class TicketBookingApplicationTests {

    @Test
    public void contextLoads() {
    }

}

这是我的 pom.xml 文件。

请帮我解决这个问题。这对我这个学生来说非常重要。

Answer 1

可能是作用域，设置为test。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

请确保具有 SpringRunner 的类在您的 /src/test/java 文件夹中。
