本文记录了解决因Java版本不匹配导致的Spring MVC项目启动失败问题的过程。通过调整Java版本、清理项目配置及重置开发环境等步骤，最终成功运行项目。

DEBUG [localhost-startStop-1] - Ignoring bean class loading failure for bean 'itemsService'
org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [cn.itcast.ssm.service.impl.ItemsServiceImpl] for bean with name 'itemsService' defined in ServletContext resource [/WEB-INF/classes/spring/applicationContext-service.xml]: problem with class file or dependent class; nested exception is java.lang.UnsupportedClassVersionError: cn/itcast/ssm/service/impl/ItemsServiceImpl : Unsupported major.minor version 52.0 (unable to load class cn.itcast.ssm.service.impl.ItemsServiceImpl)

七月 31, 2017 8:09:17 下午 org.apache.catalina.core.StandardContext listenerStart
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

背景：本人周五下班兴致勃勃想把一个以前黑马的mysql小程序改到sqlserver 来，经历：

　　1、连接sqlserver异常：Exception in thread "main" com.microsoft.sqlserver.jdbc.SQLServerException: http://www.cnblogs.com/rogge7/p/7253927.html

　　2、JDK版本异常1.8降低到1.7，message Servlet.init() for servlet springmvc threw exception

　　3、Eclipse版本降低为mars （因为最新oxygen不支持JDK1.7）， indigo我都下载好了，

　　4、无法解析类型 javax.servlet.http.HttpServletRequest ，http://www.cnblogs.com/rogge7/p/7241456.html 

　　5、属性名冲突  ，再db.properties配置文件修改后，

　　 程序跑起来还是弹出上面异常，再怎么也解决不了，

以为：是Tomcat版本的问题，

　　　　或者是太多的框架jar包整合和现在环境冲突问题（上传图片的 fileupload jar包，json交互jackson包，Validation校验的包）

　　　　重新导入表结构

　　后来先做了连接sqlserver数据库，用mybatis官方的代码方法  自动生成 数据库映射文件的，不错。

 

居然：后来思考是否在折腾异常的过程中 把源码搞坏了，找来原来源码，重新配置后果然可以运行起来。晕人。

　　不过也是在解决了上面很多问题后才可以跑起来的；同时备份源码很重要。

 

待续...

从零开始搭建一个项目骨架，最好选择合适，熟悉的技术，并且在未来易拓展，适合微服务化体系等。所以一般以Springboot作为我们的框架基础，这是离不开的了。 然后数据层，我们常用的是Mybatis，易上手，方便维护。但是单表操作比较困难，特别是添加字段或减少字段的时候，比较繁琐，所以这里我推荐使用Mybatis Plus，为简化开发而生，只需简单配置，即可快速进行 CRUD`操作，从而节省大量时间。...

​​异常通常是由于类路径问题、配置错误或类加载器问题引起的。通过仔细检查依赖、配置文件和类加载器设置，以及定期清理和重建项目，你应该能够解决这个问题。​​ 异常通常表明 Spring 框架在尝试加载一个 bean 类时失败。这个错误可能由多种原因引起，比如类路径不正确、类文件缺失或损坏，或者配置错误。在使用 Spring 与 Quartz 集成时，如果你遇到这个异常，可能是因为你配置了一个不存在的类作为 Quartz 的 Job 类，或者这个类的路径没有正确配置。
