Java – MyBatis – jdbcTypeForNull Oracle

I am using MyBatis with an Oracle 11g R2 database. I am using MyBatis 3.3 with ojdbc6 12.1.0.2. My issue is whenever I tried to insert an object that is null I get the following.

org.springframework.jdbc.UncategorizedSQLException: Error setting null
for parameter #8 with JdbcType OTHER . Try setting a different
JdbcType for this parameter or a different jdbcTypeForNull
configuration property. Cause: java.sql.SQLException: Invalid column
type: 1111

My understanding is in the latest version of JDBC null is mapped to JdbcType.OTHERS which no all drivers handle, apparently Oracle is one of them.

I tried the following in my MyBatis configuration, but still no luck.

    @Bean
    public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
        final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setTypeAliasesPackage("org.ohtech.innovationexchange.core.domain");
        sessionFactory.setTransactionFactory(springManagedTransactionFactory());
        sessionFactory.setConfigurationProperties(getProperties());
        return sessionFactory.getObject();
    }

    @Bean(name = "transactionManager")
    public DataSourceTransactionManager dataSourceTransactionManager() throws PropertyVetoException{
        return new DataSourceTransactionManager(dataSource());
    }

    @Bean
    public SpringManagedTransactionFactory springManagedTransactionFactory() {
        return new SpringManagedTransactionFactory();
    }

    private Properties getProperties() {
        final Properties myBatisProperties = new Properties();
        myBatisProperties.put("jdbcTypeForNull", "NULL");
        return myBatisProperties;
    }

I can make it work by doing the following in my mapper files but it seems really repetitive and ugly. Not sure why MyBatis is not using my properties I am passing the SqlSessionFactory bean.
