junit  运行时报错    将spring-boot-autoconfigure.1.3.5.jar  这个jar包删掉后就不报错

分析后总结的原因为 ： errorAttributes 这个类没有加载到  

                                    这个类是通过 ErrorMvcAutoConfiguration  org.springframework.boot.autoconfigure.web; 加载的

                                    ErrorMvcAutoConfiguration 而这个类只在webApplication 才会加载 ， 用junit运行其实是appApplication 所以不会加载此类

                    那么为什么删掉jar包后就不报错了呢？ 原因是webApiAutoConfiguration 注解了 @AutoConfigureAfter({WebMvcAutoConfiguration.class}); 需要在

                    WebMvcAutoConfiguration这个类之后加载，删掉jar包后这个类不存在了，所以webApiAutoConfiguration 这个类不会被加载
