导入org.springframework.test.context.junit4.SpringRunner无法解析

Question

我试图解决这个从某个时候now.But仍然我没有得到它解决。我刚刚下载了一个春天项目形式spring.io并将其作为Maven项目导入到Eclipse IDE中。之后，我得到了上述错误。

进口org.springframework.test.context.junit4不能得到解决

我重视我的代码below.Together与全pom.xml的内容。

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。

Answer 1

这可能是范围，它被设置为test。

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

请确保SpringRunner的类位于您的/src/test/java文件夹中。

Answer 2

我觉得依赖丢失：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-test</artifactId> 
    <version>4.3.10.RELEASE</version> 
    <scope>test</scope> 
</dependency>
