vfsImpl in settings is not working

[ScienJus]

In my Spring Boot Project, i want to use SpringBootExecutableJarVFS to scan my type aliases , but it is not working. VFS.getInstance will be running before Configuration.setVfsImpl. like:

because in SqlSessionFactoryBean.buildSqlSessionFactory method, VFS.getInstance will be called in configuration.getTypeAliasRegistry().registerAliases(packageToScan, typeAliasesSuperType == null ? Object.class : typeAliasesSuperType);, then setVfsImpl will be called in xmlConfigBuilder.parse

    if (hasLength(this.typeAliasesPackage)) {    // <- VFS.getInstance will be called
      String[] typeAliasPackageArray = tokenizeToStringArray(this.typeAliasesPackage,
          ConfigurableApplicationContext.CONFIG_LOCATION_DELIMITERS);
      for (String packageToScan : typeAliasPackageArray) {
        configuration.getTypeAliasRegistry().registerAliases(packageToScan,
                typeAliasesSuperType == null ? Object.class : typeAliasesSuperType);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Scanned package: '" + packageToScan + "' for aliases");
        }
      }
    }

    if (!isEmpty(this.typeAliases)) {
      for (Class<?> typeAlias : this.typeAliases) {
        configuration.getTypeAliasRegistry().registerAlias(typeAlias);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Registered type alias: '" + typeAlias + "'");
        }
      }
    }

    if (!isEmpty(this.plugins)) {
      for (Interceptor plugin : this.plugins) {
        configuration.addInterceptor(plugin);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Registered plugin: '" + plugin + "'");
        }
      }
    }

    if (hasLength(this.typeHandlersPackage)) {
      String[] typeHandlersPackageArray = tokenizeToStringArray(this.typeHandlersPackage,
          ConfigurableApplicationContext.CONFIG_LOCATION_DELIMITERS);
      for (String packageToScan : typeHandlersPackageArray) {
        configuration.getTypeHandlerRegistry().register(packageToScan);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Scanned package: '" + packageToScan + "' for type handlers");
        }
      }
    }

    if (!isEmpty(this.typeHandlers)) {
      for (TypeHandler<?> typeHandler : this.typeHandlers) {
        configuration.getTypeHandlerRegistry().register(typeHandler);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Registered type handler: '" + typeHandler + "'");
        }
      }
    }

    if (xmlConfigBuilder != null) {
      try {
        xmlConfigBuilder.parse();   // <- setVfsImpl will be called

        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Parsed configuration file: '" + this.configLocation + "'");
        }
      } catch (Exception ex) {
        throw new NestedIOException("Failed to parse config resource: " + this.configLocation, ex);
      } finally {
        ErrorContext.instance().reset();
      }
    }

my SqlSessionFactory:

@Bean
public SqlSessionFactory sqlSessionFactory() throws Exception {
    final SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
    sqlSessionFactory.setDataSource(dataSource());
    sqlSessionFactory.setTypeAliasesPackage("com.xxx.domain");
    PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
    sqlSessionFactory.setMapperLocations(resolver
            .getResources("classpath:/com/xxx/mapper/impl/*.xml"));
    sqlSessionFactory.setConfigLocation(resolver.getResource("classpath:mybatis.xml"));
    return sqlSessionFactory.getObject();
}

my mybatis.xml:

<configuration>
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <setting name="lazyLoadingEnabled" value="true"/>
        <setting name="aggressiveLazyLoading" value="false"/>
        <setting name="vfsImpl" value="com.xxx.mapper.SpringBootExecutableJarVFS"/>
    </settings>
</configuration>
