MyBatis - jdbcTypeForNull Oracle
Solution 1
"jdbcTypeForNull" is not a 'property' but a 'setting'. Can not be set by java config currently, I guess. You need a config.xml like this:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="jdbcTypeForNull" value="NULL" />
</settings>
</configuration>
and use sessionFactory.setConfigLocation(...).
For the difference between settings and properties please refer to the documentation: https://mybatis.github.io/mybatis-3/configuration.html
Solution 2
For those using the mybatis Spring Boot starter, this is the property you can add to application.properties
to correct this problem:
mybatis.configuration.jdbc-type-for-null=NULL
Solution 3
Maybe its late, but here is the solution:
@Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
sessionFactory.setTypeAliasesPackage("com.xxx.mapper");
SqlSessionFactory sqlSessionFactory = sessionFactory.getObject();
sqlSessionFactory.getConfiguration().setJdbcTypeForNull(JdbcType.NULL);
return sqlSessionFactory;
}

I'm a web developer from Columbus, Ohio. I studied Computer Science at Capital University in Columbus, where I received my bachelor's degree. In college I was heavy into C++ and Python. I dabbled my hands in Objective-C/Cocoa as well. After college I began doing web development using PHP/MySQL. I really fell in love with web development. Now I'm transitioning into Java/Spring MVC. At some point I would like to get more into ASP.NET MVC.

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.

David about 2 yearsYAML configuration really needs quotes around NULL. Thank you @pratiyush.
