1.背景：

    ssm架构中，未避免mapper.xml文件在引用对应的类文件时，通过别名的方式制定对应的类关系。如下图，通过typeAliases批量包声明的方式，避免在mapper.xml中大量使用 com.wpao.shop.model.SiteBean的方式调用，直接通过SiteBean的方式调用

2.通过批量包声明的方式在idea中出现类解析错误

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [C:\Users\dada\Downloads\workspace_5pao\wpao-webCenter\wpao-theuser\target\wpao-theuser\WEB-INF\classes\com\wpao\shop\mapper\about.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'SiteBean'.  Cause: java.lang.ClassNotFoundException: Cannot find class: SiteBean
