【报错】项目启动部署时报错：java.lang.NoSuchMethodError

报错：

项目启动部署报错：

只粘贴了部分错误在这里。

错误具体是什么，不重要，关键是这类型问题

java.lang.NoSuchMethodError

怎么解决才是最关键的问题！！！

分析：

==========================================================================================

海量的帖子/文章中都声明了这个问题的根源所在。

不是调用这个类，类中方法不存在；

就是这个方法在多个类中都有；

翻来覆去就是架包不匹配啦，版本不一致啦，冲突啦，啦啦啦乱七八糟的。好吧，怎么解决呢？

解决：

==========================================================================================

①不管你用的什么IDE，无论ecplise还是myecplise又或者idea。在解决这个问题之前，你需要懂得一件事，就是会在项目启动前，配置JVM参数。

参考：http://www.cnblogs.com/sxdcgaq8080/p/8022096.html一看就懂了。

②添加一个VM参数

-XX:+TraceClassLoading

③保存后重启项目

④发现报错和上面是哪个架包出现了问题

那么去检查

　　　　1》是不是这个架包没有下载下来

　　　　2》是不是这个架包中这个类下没有这个方法

　　　　3》是否要更换架包版本来解决这个问题

　　　　4》是否别的架包也有这个相同类的相同方法，导致找不到本方法

按照这样的思路解决问题即可。

⑤仅对应本次截图出现的问题，解决方法

　　在Stack Overflow找到相同的问题，由于对spring源码并非特别熟悉，只是提出在4.2以后上面报错的方法就被提到了spring-core架包中而不是在orm架包中，所以，需要将spring-orm架包的版本降低到<4.2以下。即可解决问题！！

　　我更改spring版本就是统一更改的，完整的pom.xml文件在最后给出。
