萬惡的 one or more listeners failed to start 和 Servlet.init() for servlet [dispatcherServlet] threw exception

maven+ssm項目啟動報錯：

org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class [org.springframework.web.context.ContextLoaderListener]
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [X:\IDEAWorkspace\easyPartTimeJob\target\easyPartTimeJob-1.0-SNAPSHOT\WEB-INF\classes\com\fireDragon\bo\AccountInfoBO.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file [X:\IDEAWorkspace\easyPartTimeJob\target\easyPartTimeJob-1.0-SNAPSHOT\WEB-INF\classes\com\fireDragon\bo\AccountInfoBO.class]; nested exception is java.lang.IllegalArgumentException

日志很詳細，但是我找了很久都找不出原因（看不懂）。百度上的博客看了個遍。然后我對着一個網上的ssm整合教程重新寫了一個整合demo，這個可以啟動了，於是我得到了一個可以跑起來的項目。

我對照各個層次的代碼發現沒錯后，對比pom文件，使用控制變量法一個一個排除（哭卿卿），發現了罪魁禍首：一個jar包：（刪除這個東西即可啟動項目），原因是jar包沖突了，ORZ。

然后訪問一個我寫的測試接口，發現報了一個新的錯誤：

我的是Spring版本問題，由5.0.8換為4.3.9即可（大俠隨機應變）。解決這兩個問題后，我的demo就可以跑通各層了。

建議：如果整合時確保代碼無誤，可以往spring版本及jar包沖突方面考慮！這種錯誤有可能人人不一樣，但是我找個BUG找了三天，覺得還是有必要記錄一下（doge）
