Google App Engine Java Production上的404错误

标签： java spring google-app-engine spring-mvc

我过去3年一直在使用Google App Engine，但之前从未遇到任何此类问题。我使用Spring-4和Objectify创建了一个项目。

我面临的问题是，本地所有网址都运行良好，但当我将其部署到appspot时，我在需要返回JSP页面的URL上遇到404错误，尽管应返回JSON或XML响应的URL，这些URL工作正常。

Appengine日志也没有提供任何相关信息。我无法理解一件事，如果它在本地运行良好，为什么它不能用于appspot。

以下是我的配置文件。

API控制器示例 

@Controller
public class CategoryController extends AbstractGenericController{

@Autowired
private CategoryService categoryService;    

@ResponseBody
@RequestMapping(value = Path.Url.API + Path.Url.CATEGORY + Path.OperationUrl.CREATE, method = RequestMethod.POST, produces = {"application/json", "application/xml" })
public Object create(@RequestBody Category category) {
    Category isExisting = categoryService.getCategoryByName(category.getCategoryName());
    if (isExisting == null) {
        Long id = categoryService.createWithID(category);
        return new Response(null, STATUS.SUCCESS, "Category created successfully. Id :" + id);
    }else{
        return new Response(null, STATUS.FAILURE, "Category already exist. Please use update category function.");
    }
 }
}

网络控制器示例 

@Controller
public class LoginLogoutController {

@RequestMapping(value = Path.Url.LOGIN)
public String loginPage(@RequestParam(value = "error", required = false) boolean error, @RequestParam(value = "maidID", required = false) String maidID, ModelMap map) {
    if (error == true) {
        map.put("error", "You have entered an invalid username or password!");
    }if( maidID != null && !maidID.equals("")){
        map.addAttribute("maidID", maidID);
    }
    if((error == true) && (maidID != null && !maidID.equals(""))){
        map.put("error", "You have entered an invalid username or password!");
        map.addAttribute("maidID", maidID);
    }
    return Path.Jsp.LOGIN_PAGE;
 }
}
