如何整合Spring数据solr和Springmvc

Question

我在集成 Spring data solr 和 Spring mvc 时遇到问题。如果只使用 spring data solr，一切都运行很好，但是要集成 spring mvc 我已经看到关于 Spring mvc.

配置的问题

存储库class：

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();        
}
}

服务class:

@Service    
public class ManufacturerServiceImpl implements ManufacturerService {

@Autowired
private ManufacturerRepository manufacturerRepository;

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

控制器class：（已更新）

@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，而且我没有集成 Spring data solr 和 Spring mvc 的经验。如何解决这个问题？非常感谢！

Answer 1

您的存储库未连接到控制器。

@Controller
public class ManagementManufacturerController {

  @Autowired
  private ManufacturerService manufactureService;
----

应该可以解决问题。您已经使用 SessionFactory 完成了此操作。 Autowired 告诉 Spring 它应该注入一个匹配类型 and/or 名称的 Bean。

€：您的服务 class 未实例化。很难说为什么，但很可能您缺少某些 @ComponentScan 注释或之前有错误。

由于服务只是包装存储库中的方法，请尝试直接自动装配存储库而不是服务 class。
