IntelliJ IDEA 2017版 Spring5 java.lang.NoSuchMethodError: org.springframework.boot.SpringApplication.([Ljava/lang/Object;)V

错误是java.lang.NoSuchMethodError: org.springframework.boot.SpringApplication.<init>([Ljava/lang/Object;)V:

因为采用了测试方法,所以引用了

@RunWith(SpringRunner.class)
这个注释,和1.4.1版本和2.0.1版本的pom,导致版本冲突,将

@RunWith(SpringRunner.class)这个去除,版本统一成2.0.1样式,就正确了
