本文解决了一个关于MyBatis配置文件中实体类别名未正确配置导致的问题。具体表现为在mybatis-config.xml中未为Address实体类配置alias，导致在解析Mapper文件时出现异常。

错误提示：

### Error building SqlSession.
### The error may exist in com/java1234/mappers/AddressMapper.xml
### The error occurred while processing mapper_resultMap[AddressResult]
### Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: 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 'Address'.  Cause: java.lang.ClassNotFoundException: Cannot find class: Address

	...

错误原因：

MyBatis配置文件中 mybatis-config.xml中(即总的配置文件)没有对该实体类配置别名；

配置如下：

	<typeAliases>
		<typeAlias alias="Student" type="com.java1234.model.Student"/><!-- 实体类别名配置 -->
		<typeAlias alias="Address" type="com.java1234.model.Address"/><!-- 实体类别名配置 -->
	</typeAliases>

报错原因：在mybatis配置文件中用到了SysUser实体类，但没有配置或引入这个实体类。 解决方案：在mybatis-config中加入配置： mybatis.typeAliasesPackage=com.sinoiov.etims.haikwanQingDao.entity 转载于:https://www.cnblogs.com/Steward-Sun/p/9661620.h...
