Question

当遇到Spring数据solr和Spring mvc时，我遇到了问题。如果只使用spring数据solr，一切运行正常，但是为了集成spring mvc我已经看到了关于配置Spring mvc的问题。

存储库类：

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();        
}
}

服务类：

@Service    
public class ManufacturerServiceImpl implements ManufacturerService {

@Autowired
private ManufacturerRepository manufacturerRepository;

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

控制器类：（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，我没有经验来整合Spring数据solr和Spring mvc。如何解决问题？非常感谢！

您的存储库未连接到Controller。

@Controller
public class ManagementManufacturerController {

  @Autowired
  private ManufacturerService manufactureService;
----

应该做的伎俩。你已经用SessionFactory做了这个。 Autowired告诉Spring它应该注入一个匹配类型和/或名称的Bean。

€：您的服务类未实例化。很难说为什么，但很可能你错过了一些@ComponentScan注释或之前有错误。

由于服务只是从存储库中包装该方法，因此尝试直接自动装配存储库而不是服务类。
