可运行的java web 项目删除一个模块后sqlSessionFactory报错，怎么改？
报错如下
ERROR - Context initialization failed

配置和包应该是正确的，删除前可运行，但是删除后报错。
也使用了search工具确定是删干净了，
这个错误应该怎么改？
你应该是把Carport这个类删掉了，导致mybatis的sqlmapper的xml配置文件中，引用到这个类时，找不到，才报的错。
解决办法：要么是把这个类找回来，要么是去依赖的那个xml中，把相关的逻辑删干净。
C:\SERVER\apache-tomcat-8.0.33\webapps\parks\WEB-INF\classes\com\soft\admin\mapper\CarportMapper.xml]
这个CarportMapper.xml里报错
Could not resolve type alias 'Carport'. Cause: java.lang.ClassNotFoundException: Cannot find class: Carport
这里告诉你没有找到Carport这个类，但是你xml文件里却用了Carport类，要么作为传参类型，要么是返回类型。
所以crtl＋F 搜索Carport ，要么改掉，要么删掉。
