求教一个 springcloud Finchley.SR2 一个很奇怪的问题， ArrayStoreException

[chenguoyu]

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

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

    @Test
    public void contextLoads() {
        System.out.println(111111);
    }

}

一个最简单的，甚至是 maven 生成的代码，在运行的时候报错

1. 这个跟 springcloud 没关系
2. 猜测应该是你 springmvc 的注解写的有问题，异常堆栈出现了 RequestMappingHandlerMapping 和 AnnotatedElementUtils，说明是 springmvc 的注解解析问题。检查下自己代码吧，EnableWebMvcConfiguration 这个配置类？

[chenguoyu]

@lil460982475 可是我用的是 springboot 自动配置的配置啊，并没有写自己的配置类

[Antihank]

//@RunWith(SpringRunner.class)
干掉这个注解

[ourslay]

pom.xml 发上来看看看

[chenguoyu]

@ourslay 感谢，找到原因了，确实是 pom 的问题，我把打包方式写成 pom 了，导致的问题
