导入org.springframework.test.context.junit4.SpringJUnit4ClassRunner无法解析

Question

我是Spring的新手,这也是我在StackOverflow上的第一个问题,所以我将尝试尽可能地理解这一点.

我正在尝试在本教程中使用Spring和Maven创建一个Web服务客户端:我收到此错误:导入org.springframework.test.context.junit4无法解析

这是我的代码:

package demo;

import hello.WsClientApplication;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //this won't import


@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = WsClientApplication.class)
public class WsClientApplicationTests {

    @Test
    public void contextLoads() {
    }

}

pom.xml如果你需要它,这是我的.

我在StackOverflow中尝试过其他一些解决方案,但我无法让它工作.

谢谢.

Answer 1

您需要添加依赖项spring-boot-starter-test:

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

Answer 2

现在,如果您使用的是最新的spring-boot,1.5.2 RELEASE,则不再提供@SpringApplicationConfiguration,而是必须使用@SpringBootTest.这里参考(Spring Boot中的 @ spring boot starter test)

Answer 3

摇篮

在gradle中,这将通过添加来完成

testCompile("org.springframework.boot:spring-boot-starter-test")

到依赖关系块,如:

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("junit:junit")
    testCompile("org.springframework.boot:spring-boot-starter-test")
}

之后,应该可以在类的顶部编写一个import语句

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

允许您使用注释:

@RunWith(SpringJUnit4ClassRunner.class)
public class MyAppTest {

}
