Spring + MyBatis - setting Data Source - mysql

Question

I'm integrating MyBatis inside my SpringBoot application. The application connects to a MySql database to fetch data. Right now I have the following classes.
MyBatisUtils.java
[...]
#Component
public class MyBatisUtils {
private static SqlSessionFactory sqlSessionFactory =
new SqlSessionFactoryBuilder().build(getConfiguration());
public static SqlSessionFactory getSqlSessionFactory(){
return sqlSessionFactory;
}
private static Configuration getConfiguration(){
Configuration configuration = new Configuration();
DataSource dataSource = null; //wrong!!!
TransactionFactory transactionFactory = new JdbcTransactionFactory();
Environment environment = new Environment("development", transactionFactory, dataSource);
configuration.addMapper(BaseQuery.class);
return configuration;
}
}
Search.java
[...]
public List dynamicSearch(){
SqlSession session = MyBatisUtils.getSqlSessionFactory().openSession();
BaseQuery mapper = session.getMapper(BaseQuery.class);
List<HashMap<String, Object>> result = mapper.select(/*query parameters*/);
return result;
}
I do not know how to set my DataSource object inside the MyBatisUtils class. Should it have some connection parameters?
Thanks for the help.

Answer 1

Define the DataSource as a Spring bean, like in this other question:
How to Define a MySql datasource bean via XML in Spring
Then inject the datasource in MyBatisUtils class.
You can also define SqlSessionFactory as a Spring bean, and directly inject it. Useful reference: http://www.mybatis.org/spring/getting-started.html

Answer 2

If you are using spring-boot already you can use mybatis-spring-boot-starter and auto-configure mybatis for free. The only thing you should worry about is the datasource. For that, properties should be set in application.properties
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
