In class org.mybatis.spring.SqlSessionFactoryBean , line 464, it invoke registerAlias(Class<?> type) directly, skip registerAliases(String packageName, Class<?> superType) . In old version ,registerAlias(Class<?> type) was invoke by registerAliases(String packageName, Class<?> superType), will skip some classes.

public void registerAliases(String packageName, Class<?> superType) {
ResolverUtil<Class<?>> resolverUtil = new ResolverUtil<>();
resolverUtil.find(new ResolverUtil.IsA(superType), packageName);
Set<Class<? extends Class<?>>> typeSet = resolverUtil.getClasses();
for (Class<?> type : typeSet) {
// Ignore inner classes and interfaces (including package-info.java)
// Skip also inner classes. See issue #6
if (!type.isAnonymousClass() && !type.isInterface() && !type.isMemberClass()) {
registerAlias(type);
}
}

String alias = type.getSimpleName();
Alias aliasAnnotation = type.getAnnotation(Alias.class);
if (aliasAnnotation != null) {
