只粘貼了部分錯誤在這裏。

錯誤具體是什麼，不重要，關鍵是這類型問題

java.lang.NoSuchMethodError

怎麼解決纔是最關鍵的問題！！！

 

 

 

分析：

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

海量的帖子/文章中都聲明瞭這個問題的根源所在。

不是調用這個類，類中方法不存在；

就是這個方法在多個類中都有；

翻來覆去就是架包不匹配啦，版本不一致啦，衝突啦，啦啦啦亂七八糟的。好吧，怎麼解決呢？

 

 

解決：

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

①無論你用的什麼IDE，不管ecplise仍是myecplise又或者idea。在解決這個問題以前，你須要懂得一件事，就是會在項目啓動前，配置JVM參數。

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

 

②添加一個VM參數

-XX:+TraceClassLoading

 

③保存後重啓項目

 

④發現報錯和上面是哪一個架包出現了問題

那麼去檢查

　　　　1》是否是這個架包沒有下載下來

　　　　2》是否是這個架包中這個類下沒有這個方法

　　　　3》是否要更換架包版原本解決這個問題

　　　　4》是否別的架包也有這個相同類的相同方法，致使找不到本方法

按照這樣的思路解決問題便可。

 

⑤僅對應本次截圖出現的問題，解決方法

　　在Stack Overflow找到相同的問題，因爲對spring源碼並不是特別熟悉，只是提出在4.2之後上面報錯的方法就被提到了spring-core架包中而不是在orm架包中，因此，須要將spring-orm架包的版本下降到<4.2如下。便可解決問題！！

　　

 

　　我更改spring版本就是統一更改的，完整的pom.xml文件在最後給出。
