Spring Framework IllegalArgumentException'dataSource'或'jdbcTemplate'是必需的JAVA

Question

I am trying to write spring application which is annotation configured. I have defined a dataSource and jdbcTemplate and i am sure that spring initializes them (when commented them i have an exception which tells me that this beans are not initialized). I have no idea why i have this exception when beans are initialize. I will copy xml, dao class and stacktrace.

xml

Answer 1

I think you should drop the autowiring of jdbcTemplate in your DomainsDao and inject your dataSource instead. Then get the jdbcTemplate by calling the org.springframework.jdbc.core.support.JdbcDaoSupport#getJdbcTemplate method.

example:

@Repository
public class DomainsDao extends JdbcDaoSupport {

    @Autowired
    private MessageSourceAccessor msa;

    @Autowired
    public void setDs(DataSource dataSource) {
         setDataSource(dataSource);
    }

    public List<Domain> getInactiveDomains() {
        return getJdbcTemplate().query(msa.getMessage("sql.pass.domain.select_inactive"), new DomainRowMapper());
    }
    public int getDomainId(String name) {
        String sql = msa.getMessage("sql.pass.domain.select_by_name");
        Object[] args = new Object[] { name };
        return getJdbcTemplate().queryForObject(sql, args, Integer.class);
    }
}

If you still want to inject your own jdbcTemplate a similar approach is required:

@Repository
public class DomainsDao extends JdbcDaoSupport {

    @Autowired
    private MessageSourceAccessor msa;

    @Autowired
    public void setJT(JdbcTemplate jdbcTemplate) {
         setJdbcTemplate(jdbcTemplate);
    }

    public List<Domain> getInactiveDomains() {
        return getJdbcTemplate().query(msa.getMessage("sql.pass.domain.select_inactive"), new DomainRowMapper());
    }
    public int getDomainId(String name) {
        String sql = msa.getMessage("sql.pass.domain.select_by_name");
        Object[] args = new Object[] { name };
        return getJdbcTemplate().queryForObject(sql, args, Integer.class);
    }
}

Answer 2

Can you please try this,

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource" />
</bean>

Answer 3

The problem is that the JdbcDaoSupport class that you are inheriting from already has a jdbcTemplate property that you need to set. The JdbcDaoSupport checks whether you have provided either the jdbcTemplate or dataSource property in its afterPropertiesSet method. However you are declaring and injecting your own jdbcTemplate meaning DomainsDao has two jdbcTemplate properties (one you declare plus one inherited from JdbcDaoSupport)

You can solve this by removing the extends JdbcDaoSupport part from your calss declaration.

Alternatively if you really want to inherit from JdbcDaoSupport then change your class as follows

@Repository
public class DomainsDao extends JdbcDaoSupport {

    @Autowired
    private MessageSourceAccessor msa;

    @Autowired
    public DomainsDao (JdbcTemplate jdbcTemplate){
       setJdbcTemplate(jdbcTemplate);
    }

    public List<Domain> getInactiveDomains() {
        return getJdbcTemplate().query(msa.getMessage("sql.pass.domain.select_inactive"), new DomainRowMapper());
    }
public int getDomainId(String name) {
        String sql = msa.getMessage("sql.pass.domain.select_by_name");
        Object[] args = new Object[] { name };
        return getJdbcTemplate.queryForObject(sql, args, Integer.class);
    }
}
