Question

I have something like this:

class MyBean {
    @Autowired
    @Qualifier("jdbcTemplate")
    @BeanProperty
    var jdbcTemplate : JdbcTemplate = null
}

Spring complains that it can’t find a bean of type JdbcTemplate and refuses to autowire. My spring.xml has:

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.simple.SimpleJdbcTemplate">
    <constructor-arg ref="dataSource" />
</bean>

If I change the type of jdbcTemplate in MyBean from JdbcTemplate to SimpleJdbcTemplate then it works. My question is why is it apparently ignoring the Qualifier annotation? Am I doing something wrong?

Answer 1

It has nothing to do with @Qualifier. SimpleJdbcTemplate is not a subclass of JdbcTemplate, therefore it cannot be injected into a field of type JdbcTemplate.
