Question

尝试使用Velocity设置Spring项目时出现以下错误。

PageNotFound - No mapping found for HTTP request with URI [/SpringMVCVelocity/Enquiries/viewAllEnquiries] in DispatcherServlet with name 'mvc-dispatcher'

我已将spring context.xml设置为 -

我的控制器是：

@Controller
@RequestMapping("/Enquiries")
@SessionAttributes({"enqList", "search"})

public class EnquiryController {

    private static final Logger logger = Logger.getLogger(EnquiryController.class);
    private PagedListHolder<Enquiry> enqList = null;
    private int pageSize = 10;

    @Autowired
    private EnquiryDao enquiryDao;

    @RequestMapping("/viewAllEnquiries")
    public String  getAllEnquiries(@RequestParam(required=false) String page, Model model) {

        if ("next".equals(page) && enqList != null) {
            enqList.nextPage();
        } else if ("previous".equals(page) && enqList != null) {
            enqList.previousPage();
        } else {
            // well there is no page parameter, so it must be a new request
            enqList = new PagedListHolder<Enquiry>(enquiryDao.getAllEnquiries());
            enqList.setPageSize(pageSize);
        }
        model.addAttribute("search", new Search());
        model.addAttribute("enqList", enqList);

        return "viewAllEnquiries";
    }

甚至没有调用此控制器。但它确实成功地通过以下方式解决了欢迎视图：

<mvc:view-controller path="/" view-name="welcome"/>

Answer 1

问题解决了，我没有扫描控制器（上下文：组件扫描），也没有在Spring上下文中连接bean。

为了解决这个问题，我通过弹簧注射添加了它：

<bean id="enquiryDao" class="ecommerce.dao.EnquiryDao"/>
<bean id="enquiryController" class="ecommerce.controller.EnquiryController">
    <property name="enquiryDao" ref="enquiryDao"/>
</bean>
