Spring Framework IllegalArgumentException 'dataSource' o 'jdbcTemplate' è richiesto JAVA

Question

Sto provando a scrivere un'applicazione a molla che è annotata configurata. Ho definito un dataSource e jdbcTemplate e sono sicuro che spring li inizializza (quando li ho commentati ho un'eccezione che mi dice che questo bean non è inizializzato). Non ho idea del motivo per cui ho questa eccezione quando i fagioli sono inizializzati. Copierò xml, classe dao e stacktrace.

xml

Answer 1

Penso che si dovrebbe cadere l'autowiring di jdbcTemplate nel vostro DomainsDao e iniettare il vostro dataSource invece. Quindi ottenere il jdbcTemplate chiamando il metodo org.springframework.jdbc.core.support.JdbcDaoSupport#getJdbcTemplate.

esempio:

@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); 
    } 
} 

Se si vuole ancora di iniettare il proprio jdbcTemplate è necessario un approccio simile:

@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

Potete per favore provare questo,

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

Answer 3

Il problema è che la classe JdbcDaoSupport che si eredita da già ha un Proprietà jdbcTemplate che è necessario impostare. JdbcDaoSupport controlla se è stata fornita la proprietà jdbcTemplate o dataSource nel suo metodo afterPropertiesSet. Comunque stai dichiarando e iniettando il tuo jdbcTemplate nel significato DomainsDao ha due proprietà jdbcTemplate (una dichiarata più una ereditata da JdbcDaoSupport)

Puoi risolvere questo rimuovendo la parte estesa di JdbcDaoSupport dalla tua dichiarazione di calss.

In alternativa, se si vuole veramente di ereditare da JdbcDaoSupport quindi modificare la classe come segue

@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); 
    } 
}
