I found answers say it possible to autowire inside rowmapper,
If you want ScoreMapper instances to have ScoreCreator scoreCreator be injected with a Spring bean, the ScoreMapper instance itself must be a Spring bean, ie. created and managed by Spring
Or by adding @Component
You can define PersonUtility class as spring bean adding @component over the class.
But currently RowMapper is instantiated with new in jdbcTemplate.query:
jdbcTemplate.query(SQL, new Object[] {}, new MyRowMapper())
And I can't autowire Spring managed ObjectMapper inside
public class MyRowMapper implements RowMapper<Map<Integer, Type>> {
@Autowired
@Qualifier("myObjectMapper")
ObjectMapper objectMapper;
How should I refactor current code to manage bean row mapper?
RowMapper is a thread safe class. That means, it's single instance can be shared amongst multiple threads. So, that means, you can let it be a singleton class and let spring handle it's lifecycle (Using one of those annotation like @Component). And wherever you want to use it's instance, just autowire/inject existing instance rather than instantiating it every time (new)
@Component
public class MyRowMapper implements RowMapper<Map<Integer, Type>> {
@Autowired
@Qualifier("myObjectMapper")
ObjectMapper objectMapper;
And then
class ASingletonClass(){
@Autowired MyRowMapper myRowMapper;
public MyRowMapper myAweSomeMethod(){
return jdbcTemplate.query(SQL, new Object[] {}, myRowMapper)
}
}
