如何整合Spring數據Solr和Spring MVC

Question

當集成Spring數據solr和Spring mvc時，我遇到了問題。 如果僅使用spring數據solr，一切運行都很好，但是要整合spring mvc，我已經看到了有關配置Spring mvc的問題。

存儲庫類：

public class ManufacturerRepositoryImpl implements ManufacturerRepository{

private Logger logger = Logger.getLogger(ManufacturerRepositoryImpl.class);

@Autowired
private SessionFactory factory;

@SuppressWarnings("unchecked")
public List<Manufacturer> getAllManufacturer() {        
    Query query = factory.getCurrentSession().createQuery("SELECT m FROM Manufacturer m");
    return query.list();        
}
}

服務等級：

@Service    
public class ManufacturerServiceImpl implements ManufacturerService {

@Autowired
private ManufacturerRepository manufacturerRepository;

public List<Manufacturer> getAllManufacturer() {
    return manufacturerRepository.getAllManufacturer();
}
}

控制器類：（ UPDATED ）

@Controller
public class ManagementManufacturerController {
@Autowired     **// UPDATED**
private ManufacturerService manufactureService;

@RequestMapping(value="/manageManufacturer")
public String getAllManufacturers(HttpServletRequest request, 
                                          HttpServletResponse response,
                                          ModelMap model) {

    List<Manufacturer> manuList = manufactureService.getAllManufacturer();
    model.put("manuList", manuList);

    return "manageManufacturer";
}
}

JSP：

<c:forEach var="renter" items="${manuList}">
    <c:out value="${renter.id}" />
    <c:out value="${renter.name}" />
</c:forEach> --%>

似乎缺少Servlet上下文或任何文件，而且我還沒有集成過Spring數據Solr和Spring MVC的經驗。 如何解決該問題？ 非常感謝 ！

Answer 1

您的存儲庫未連接到控制器。

@Controller
public class ManagementManufacturerController {

  @Autowired
  private ManufacturerService manufactureService;
----

應該做到的。 您已經使用SessionFactory做到了。 Autowired告訴Spring它應該注入一個與類型和/或名稱匹配的Bean。

€：您的服務等級未實例化。 很難說為什么，但是很可能您缺少某些@ComponentScan批注，或者之前有錯誤。

由於服務只是包裝了存儲庫中的方法，因此請嘗試直接自動連接存儲庫而不是服務類。
