问题是,每次我运行项目时,都会出现来自org.springframework.beans.factory.UnsatisfiedDependencyException弹出窗口的错误。
我已经尝试了几个带有答案的相关问题,但问题尚未解决。
现场数据服务.java
@Component
public interface FieldDataService {
public FieldData getFieldData() throws SQLException, Exception;
}
FieldDataServiceImpl.java
@Component
public class FieldDataServiceImpl implements FieldDataService {
@Autowired
FieldDataDao fieldDataDao;
@Override
public FieldData getFieldData() throws SQLException, Exception {
return this.fieldDataDao.getFieldData();
}
}
田地数据道.java
@Component
public interface FieldDataDao {
public FieldData getFieldData() throws SQLException, Exception;
}
FieldDataDaoImpl.java
@Component
public class FieldDataDaoImpl implements FieldDataDao{
@Autowired
private SqlSession sqlSession;
@Override
public FieldData getFieldData() throws SQLException, Exception {
FieldData result = new FieldData();
try {
result = this.sqlSession.selectOne("getFieldData");
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}
现场数据.java
