MyBatis Type Handlers for PostGIS
The MyBatis type handlers supporting geometry types introduced in PostGIS: JDBC Geometry API
Requirements
Java 7 or higher.
The latest PostGIS JDBC API which it depends on was using the JRE7 version of PostgreSQL JDBC, so it requires Java 7 or higher.
Installation
If you are using Maven add the following dependency to your pom.xml:
<dependency>
    <groupId>com.eyougo</groupId>
    <artifactId>mybatis-typehandlers-postgis</artifactId>
    <version>1.0</version>
</dependency> 
Configuration
- If you are using MyBatis alone, add the type handlers to your mybatis-config.xmlas follow:
<typeHandlers>
    <!-- ... -->
    <typeHandler handler="com.eyougo.mybatis.postgis.type.PointTypeHandler" />
    <typeHandler handler="com.eyougo.mybatis.postgis.type.PolygonTypeHandler" />
</typeHandlers> 
- If you are using MyBatis with Spring, add the type handlers package to the Spring configuration as follow:
With XML Configuration
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <!-- ... -->
    <property name="typeAliasesPackage" value="com.eyougo.mybatis.postgis.type" />
</bean> 
Or with Java configuration
@Bean
public SqlSessionFactory sqlSessionFactory(Configuration config) {
    SqlSessionFactoryBean factory = new SqlSessionFactoryBean();
    // ...
    factory.setTypeHandlersPackage("com.eyougo.mybatis.postgis.type");
    return factory.getObject();
} 
- If you are using MyBatis with Spring Boot, add the type handlers package to the configuration file as follow:
application.properties
mybatis.type-handlers-package = com.eyougo.mybatis.postgis.type 
Or application.yml
mybatis:
    type-handlers-package: com.eyougo.mybatis.postgis.type
