junit测试问题

运行

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
@Configuration
public class ControllerTest {

    @Test
    public void sendTest(){
        System.out.println(new java.util.Date().toLocaleString());
        System.out.println("12313");
    }
}

报错：

16:54:38.026 [main] INFO org.springframework.test.context.support.AnnotationConfigContextLoaderUtils - Could not detect default configuration classes for test class [com.example.xxx.Test.ControllerTest]: ControllerTest does not declare any static, non-private, non-final, nested classes annotated with @Configuration.
java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations$SearchStrategy

 

原因：以下pom.xml文件中指定了版本，把对应的版本号都注释就解决
