Springboot：解决FailedtoloadApplicationContext问题
最近在做spring junit 做单元测试中，报 Failed to load ApplicationContext 错误。
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.st.context.SpringBootTest;
import st.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {
@Autowired
private Person person;
@Test
public void contextLoads(){
System.out.println(person);
}
}
unit和test也都配置了相关依赖
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
spring framework<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
但还是报 Failed to load ApplicationContext 错误

⼀直不到原因，卡壳了⽼半天，在⽹上也了好多资料，也没有效果。
最后我的解决办法是加⼀个⾃动配置注解
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
最终完美解决，希望能帮助到各位
