Configure multiple data sources spring boot

First, the use of multiple data sources arranged jdbc

Data source configuration 1.yml

 

 

 

2. Configure class

        the SqlSessionFactoryBean the bean = new new the SqlSessionFactoryBean (); 
        bean.setDataSource (DataSource); 
        bean.setMapperLocations ( 
                // set mybatis xml position where 
                new new PathMatchingResourcePatternResolver () getResources (. "CLASSPATH *:. Mapping / Mapper / * XML" ));

                new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/test01/*.xml"));
        return bean.getObject();
    }
}

3. Test class

public class SqlserverServiceTest {
     @Resource
     JdbcTemplate vlmsJdbcTemplate;

     @Autowired
     NamedDb db;

    @Test
    public void testTime() {


        Map<String,Object> map = vlmsJdbcTemplate.queryForMap("SELECT * FROM wx_user WHERE user_id='***'");
        System.out.println(map);
        Record rc = db.findFirst("SELECT * FROM SYSC03 WHERE CGRDM='***'");
        System.out.println(rc);

    }


}

 

Second, the use of multiple data sources arranged mybatis

Data source configuration 1.yml

 

 

 2.prom.xml Configuration

        <!--引入dynamic-datasource-spring-boot-starter。-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
            <version>2.5.6</version>
        </dependency>

3. Test class

// default to the primary data source using @DS ( "Data Source Name") using the new additional data sources 
@DS ( "VLMs" ) 
 public  interface BiZcPlanShipmentMapper the extends IBaseMapper <BiZcPlanShipment> { 

    Page <the Record> getDataList (@Param ( "filterPage ") Page <the Record> Page); 

}

The second configuration may refer to mybatis  https://mp.baomidou.com/guide/dynamic-datasource.html
