스프링부트 2.0 에서  멀티 db를 사용하고 mybaits와 mysql 을 사용해보자.. 

/main/resources/application.properties

파일을 열고 환경 설정을 한다. 

#db순서
spring.first.datasource.type=org.apache.tomcat.jdbc.pool.DataSource 
spring.first.datasource.driverClassName=net.sf.log4jdbc.sql.jdbcapi.DriverSpy
spring.first.datasource.jdbc-url=db주소
spring.first.datasource.username=아디
spring.first.datasource.password=패스워드
spring.first.datasource.connectionProperties=useSSL=false;useUnicode=yes;characterEncoding=UTF-8;serverTimezone=UTC 

#db순서
spring.second.datasource.type=org.apache.tomcat.jdbc.pool.DataSource 
spring.second.datasource.driverClassName=com.mysql.jdbc.Driver
spring.second.datasource.jdbc-url=db주소
spring.second.datasource.username=아디.
spring.second.datasource.password=패스워드.
spring.second.datasource.connectionProperties=useSSL=false;useUnicode=yes;characterEncoding=UTF-8;serverTimezone=UTC 

JSP 페이지 사용을 위해서

#JSP를 사용하겠다.
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp

문자를 UTF-8사용 설정

spring.http.encoding.charset=UTF-8 

첫번째 DB파일 설정

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class FirstDataSourceConfig {
@Bean 
@ConfigurationProperties(prefix = "spring.first.datasource") 
public DataSource firstDataSource() 
{
return DataSourceBuilder.create().build(); 
} 
@Bean public SqlSessionFactory firstSqlSessionFactory(DataSource firstDataSource, ApplicationContext applicationContext) throws Exception 
{
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); 
sqlSessionFactoryBean.setDataSource(firstDataSource); 
sqlSessionFactoryBean.setMapperLocations(applicationContext.getResources("classpath:mapper/first/*.xml")); 
return sqlSessionFactoryBean.getObject(); 
}
@Bean public 
SqlSessionTemplate firstSqlSessionTemplate(SqlSessionFactory firstSqlSessionFactory) throws Exception 
{
return new SqlSessionTemplate(firstSqlSessionFactory); 
}

}

2번째 DB파일 설정

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SecondDataSourceConfig {
@Bean 
@ConfigurationProperties(prefix = "spring.second.datasource") 
public DataSource secondDataSource() 
{
return DataSourceBuilder.create().build(); 
} 
@Bean public SqlSessionFactory secondSqlSessionFactory(DataSource secondDataSource, ApplicationContext applicationContext) throws Exception 
{
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); 
sqlSessionFactoryBean.setDataSource(secondDataSource); 
sqlSessionFactoryBean.setMapperLocations(applicationContext.getResources("classpath:mapper/second/*.xml")); 
return sqlSessionFactoryBean.getObject(); 
}
@Bean public 
SqlSessionTemplate secondSqlSessionTemplate(SqlSessionFactory secondSqlSessionFactory) throws Exception 
{
return new SqlSessionTemplate(secondSqlSessionFactory); 
}

}
