记一次重大的开发运行问题解决

Posted on

前言

最近已经过完了年，我也结束了我年前的前端工作，转向了我本来就在项目的工作，还是那个将近60w 行代码的系统，这次就比较难受，需要再加一个支付的渠道、修改商户的进件流程。

所以啊，各种各样的问题就有出现了，这个问题真的搞得我头很大，问题来了。

问题简介

Tomcat、 Hibernate、 Spring MVC、 slf4j

这些东西相互交织产生的一个莫名其妙的问题。

第一眼看到这个，脑子没有一丝丝解决的办法，没得办法只能硬上了。

解决办法

  1. 用眼看
    从结果来看，这个显然是不行的。
  2. 度娘
    emmmmmmm……….我拒绝
  3. 谷歌
    stackoverflow 果然牛逼

    I had two version of slf4j-api in my classpath - slf4j-api-1.6.1.jar as well as slf4j-api-1.5.8.jar. I removed the latter and that solved my issue with

    "java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.engine.ConfigurationImpl".

抱着试试的态度。 嘿，还真的是两个

总结

在你遇到问题时，不要慌张，不要放弃，冷静分析，总结前人的经验，当问题解决时，你就会发现，编程真的可能会成为我一生的爱好和职业。
