SpringBoot loads TypeAlias of Mybatis

After springboot is typed as jar, running on linux will report the problem that the entity class corresponding to type alias cannot be found. This is the problem of springboot scanning packages.

The DefaultVFS of Mybatis is used by default in the project, but in the environment of springboot, there will be problems with the DefaultVFS of Mybatis, so you can only modify VFS in order to be clearly visible.

Directly post the code: @ Bean public SqlSessionFactory sqlSessionFactoryBean () throws Exception {logger.info ("load SpringBootVFS"); / / DefaultVFS has a problem in obtaining jar. Using springboot can only modify VFS.addImplClass (SpringBootVFS.class); SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean (); sqlSessionFactoryBean.setDataSource (dataSource ()); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver (); Resource [] resources1 = resolver.getResources ("classpath*:/mybatis/*.xml") Resource [] resources2 = resolver.getResources ("classpath*:/mysql/mapper/*.xml"); Resource [] resources = (Resource []) ArrayUtils.addAll (resources1,resources2); sqlSessionFactoryBean.setMapperLocations (resources); sqlSessionFactoryBean.setTypeAliasesPackage ("com.xxx.xx.entity"); return sqlSessionFactoryBean.getObject ();} springboot packages errors that cannot be found in the typeAlias class name of the startup times mybatis

The springBoot project works well on IDEA, but there is an error running after packaging. The error is roughly that typeAlias cannot find the XX class when mybatis parses Mapper.xml.

The tag in Mapper:

This way of writing works in IDEA. If there is no problem, there is a problem with packaging.

Write it correctly:

The parameterType in the code must use the full path or there will be an error.
