idea启服务时，发现服务启不来。首先是确定了更新svn的配置文件，再次启动服务发现还是报同样的错误。下面把报错日志完整的截出来，也整理一下自己为什么分析时走了弯路。

下面是报错日志信息：

错误日志分析：在这个地方本应该是根据

错误日志1

Caused by: java.lang.ClassNotFoundException: Cannot find class: com.ztesoft.zsmart.zcm.**monitorqryRefList**.model.nmsdb.NmCompRefValueDto 这条报错信息的主线去查找，

而自己在排查问题是确是根据这条报错信息的主线去排查的

错误日志2

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'agentProbeController': Unsatisfied dependency expressed through field 'agentProbeService';

这两条日志数据都是报错信息，然后LZ就贴着错误日志的相关信息去google，确实有很多介绍，但是都和我遇到的问题都不match,后来停顿了一下，上个厕所发现自己思维倒挂了，这两个日志信息就像一颗大树，错误日志1是树根，错误日志2才是树叶，然后就去确认一下NmCompRefValueDto 类的路径，发现报错路径中多了一个**monitorqryRefList**文件夹，对比了svn也没有提示different,仔细看确实是有问题。

关键是svn update多次，怎么就没有覆盖呢，也没有提示出不同，这个就很奇怪了，让我尝试了rebuild工程，通过maven重新packageing,最后倒在这路径上。

谨记：下次遇到棘手的问题，一定要缕出报错的问题根处，不然会多走一些弯路，浪费时间。
