These days build a simple framework for spring4.1.2+mybatis3.2.8.

Discover MyBatis's Sqlsessionfactorybean can configure the Typealiasespackage property to automatically alias domain.

If my domain is under a different package, then this configuration does not support wildcard scan package path? The following modifications:

Before Retrofit: Applicationcontext.xml configuration:

Off Topic:

@org.apache.ibatis.type.alias (value = "user") annotations can be added to domain under the Typealiasespackage configuration path, and if this annotation is added, the alias uses the name specified by this annotation. If not configured, the default is the first letter of the class name lowercase.
