1.项目之前是可以使用的，所以排除掉项目配置问题以及代码问题；
2.根据在网上都到的信息，更改过MyEclipse里面的配置，打开window——Preferences，搜索maven，将如图所示的复选框取消掉，但是没有什么作用，这个是用于自动更新，取消掉就可以
3.在多方排查无果之后，通过plsql工具，登录数据库查看是否是数据库的问题，然后发现登不上去了，提示ORA-28547 连接服务器失败，可能是Oracle Net管理错误，查看Oracl服务都正常启动着，没办法继续网上查；
最终解决方法
在本地找到Oracle安装目录下的linster.ora文件，删除PRORAM和ENVS这两行，然后重启服务或者重启下系统，再进行尝试，即可解决问题。
