Autowireing of Qualified Datasource not working - spring

Question

I have a SpringBoot 2.0.4 app, and I am using JdbcTemplates. I had it all working, when I got a requirement to do a data transfer between 2 DBs.
So I set up 2 Data Sources like this:
#Configuration
public class OracleConfiguration {
#Bean(name = "oracleDataSource")
#ConfigurationProperties(prefix = "oracle.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
}
and my DAO is like this:
#Repository
#Component
public class personDao extends JdbcDaoSupport {
static final Logger logger = LoggerFactory.getLogger(CymNetworkDao.class);
#Autowired
public void setDs(#Qualifier("oracleDataSource") DataSource dataSource) {
setDataSource(dataSource);
}
public List<PersonBean> findAll() {
List<PersonBean> result = getJdbcTemplate().query("SELECT * FROM PERSON", new PersonRowMapper());
return result;
}
}
I am getting this error:
Unsatisfied dependency expressed through field 'jdbcTemplate';
nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'org.springframework.jdbc.core.JdbcTemplate' available:
expected at least 1 bean which qualifies as autowire candidate. Dependency annotations:
{#org.springframework.beans.factory.annotation.Autowired(required=true), #org.springframework.beans.factory.annotation.Qualifier(value=oracleJdbcTemplate)}
My reading of tutorials was telling me to just autowire the datasource, and the jdbcTemplate would create itself. Am I qualifying wrong or something else?

Answer 1

you should create jdbcTemplate by injecting DataSource like following example
#Repository
public class personDao {
private JdbcTemplate oracleJdbcTemplate;
#Autowired
public void setDataSource(#Qualifier("oracleDataSource") DataSource dataSource) {
this.oracleJdbcTemplate = new JdbcTemplate(dataSource);
}
And in error message it clearly shows it was missing JdbcTemplate bean
#org.springframework.beans.factory.annotation.Qualifier(value=oracleJdbcTemplate)}
