我是Spring
和maven
的新手。
我有一个SQL Server
,它有一个数据库和一个表。
目的是读取并显示数据。
我遵循多个链接来执行此操作,最后是我的项目结构:。
这是我的课程和配置:
WelcomeController:
@Controller
public class WelcomeController {
@Autowired
private FancoilStatisticsDao fancoilStatisticsDao;
@RequestMapping("/welcome")
public ModelAndView displayDetail(ModelAndView model) throws IOException{
FancoilStatistics fancoilStatistics=fancoilStatisticsDao.displayList();
ModelAndView mav = new ModelAndView("welcome");
mav.addObject("fancoilStatistics", fancoilStatistics);
return mav;
}
}
FancoilStatistics:
public class FancoilStatistics {
private String dateOfQt;
private String qtyPlan;
private String qtActual;
private String qtChecked;
public String getDateOfQt() {
return dateOfQt;
}
public String getQtyPlan() {
return qtyPlan;
}
public String getQtActual() {
return qtActual;
}
public String getQtChecked() {
return qtChecked;
}
public void setDateOfQt(String dateOfQt) {
this.dateOfQt = dateOfQt;
}
public void setQtyPlan(String qtyPlan) {
this.qtyPlan = qtyPlan;
}
public void setQtActual(String qtActual) {
this.qtActual = qtActual;
}
public void setQtChecked(String qtChecked) {
this.qtChecked = qtChecked;
}
}
FancoilStatisticsDao:
public interface FancoilStatisticsDao {
public FancoilStatistics displayList();
}
FancoilStatisticsDaoImp:
public class FancoilStatisticsDaoImp implements FancoilStatisticsDao {
@Autowired
DataSource datasource;
@Autowired
JdbcTemplate jdbcTemplate;
@Override
public FancoilStatistics displayList() {
// TODO Auto-generated method stub
String sql = "select top(1) * from ArvandMIS.dbo.Pln_Fc_Monitor order by Tarikh desc;" ;
List<FancoilStatistics> fancoilStatistics = jdbcTemplate.query(sql, new FancoilStatisticsMapper());
return fancoilStatistics.size() > 0 ? fancoilStatistics.get(0) : null;
}
}
class FancoilStatisticsMapper implements RowMapper<FancoilStatistics> {
public FancoilStatistics mapRow(ResultSet rs, int arg1) throws SQLException {
FancoilStatistics fancoilStatistics = new FancoilStatistics();
fancoilStatistics.setDateOfQt(rs.getString("Tarikh"));
fancoilStatistics.setQtyPlan(rs.getInt("QtyPlan")+"");
fancoilStatistics.setQtActual(rs.getInt("QtyActual")+"");
fancoilStatistics.setQtActual(rs.getInt("QtyChecked")+"");
return fancoilStatistics;
}
}

现在我的问题是我做对了吗?
并且where and how
应该创建连接详细信息吗?如用户名,网址,密码等。
我已经在Internet上看到一些帖子,它们告诉在资源目录中创建bean文件,但是我没有该目录。
也有人说创建.properties
文件。
根据我的结构,我该怎么做?
请注意,我不想使用JPA
。
