Spring Framework IllegalArgumentException 'dataSource' hoặc 'jdbcTemplate' là bắt buộc JAVA

Question

Tôi đang cố gắng viết ứng dụng mùa xuân được chú thích cấu hình. Tôi đã xác định một dataSource và jdbcTemplate và tôi chắc chắn rằng mùa xuân khởi tạo chúng (khi nhận xét chúng tôi có một ngoại lệ mà nói với tôi rằng đậu này không được khởi tạo). Tôi không có ý tưởng tại sao tôi có ngoại lệ này khi đậu được khởi tạo. Tôi sẽ sao chép xml, lớp dao và stacktrace.

Answer 1

Tôi nghĩ bạn nên thả autowiring của JdbcTemplate trong DomainsDao của bạn và tiêm dataSource của bạn để thay thế. Sau đó lấy jdbcTemplate bằng cách gọi phương thức org.springframework.jdbc.core.support.JdbcDaoSupport#getJdbcTemplate.

dụ:

@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); 
    } 
} 

Nếu bạn vẫn muốn tiêm riêng bạn jdbcTemplate phương pháp tương tự được yêu cầu:

@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

bạn có thể vui lòng thử điều này,

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

Answer 3

Vấn đề là rằng lớp JdbcDaoSupport mà bạn đang kế thừa từ đã có một jdbcTemplate tài sản mà bạn cần phải thiết lập. JdbcDaoSupport kiểm tra xem bạn đã cung cấp thuộc tính jdbcTemplate hoặc dataSource trong phương thức afterPropertiesSet của nó hay chưa. Tuy nhiên bạn đang khai báo và chèn jdbcTemplate của riêng bạn có nghĩa là DomainsDao có hai thuộc tính jdbcTemplate (một trong những bạn khai báo cộng với một thuộc tính được thừa kế từ JdbcDaoSupport)

Bạn có thể giải quyết điều này bằng cách loại bỏ phần mở rộng JdbcDaoSupport khỏi khai báo calss của bạn.

Ngoài ra nếu bạn thực sự muốn kế thừa từ JdbcDaoSupport sau đó thay đổi lớp học của bạn như sau

@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); 
    } 
}
