测试类自动注入失败：@RunWith(SpringRunner.class)爆红详解

代码如下：

@RunWith(SpringRunner.class)
@SpringBootTest
public class ProjectFontControllerTest {

｝

因为缺少依赖，添加此依赖问题，如果有冲突可切换版本：

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
		<groupId>junit</groupId>
		<artifactId>junit</artifactId>
		<version>4.12</version>
		<!--<scope>test</scope>-->
	</dependency>
