是否可以在方法中使用多个@RequestMapping spring注释？喜欢:

@RequestMapping("/")
@RequestMapping("")
@RequestMapping("/welcome")
public String welcomeHandler(){
 return("welcome");
}

Is there a way to get the complete path value after the requestMapping @PathVariable values have been parsed?

这就是: /{id}/{restOfTheUrl}应该可以解析/1/dir1/dir2/file.html成id=1和restOfTheUrl=/dir1/dir2/file.html

任何想法,将不胜感激.

我想自己处理请求和会话属性,而不是将其留给spring @SessionAttributes,例如登录cookie处理.

我只是无法弄清楚如何HttpRequest在控制器中访问from,我需要一种方法去上面一层@RequestAttribute并访问它HttpRequest自己.使用Stripes来实现ApplicationContext和调用getAttribute().

此外,传递HttpServletRequestas参数似乎不起作用:

@RequestMapping(value="/") public String home(HttpServletRequest request){
    System.out.println(""+request.getSession().getCreationTime());
    return "home"; 
}

上述方法不打印任何内容.

你对此有什么建议吗？

我有一个支持这两个GET和POST请求的资源.这是示例资源的示例代码:

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter, two @RequestParam parameters, HttpServletRequest request)
    throws ParseException {
        LONG CODE
}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, BindingResult result)
        throws ParseException {
        SAME LONG CODE with a minor difference
}

两个方法中的代码实际上是相同的,除了让我们说变量定义.这两种方法可以很容易地组合使用method = {RequestMethod.POST, RequestMethod.GET},并且if内部简单.我尝试,但它不工作的,因为这两种方法具有不同的参数在末端,即HttpServletRequest和BindingResult(所述@RequestParam的不要求,因此在不需要的POST请求).任何想法如何结合这两种方法？

我有一个简单的控制器,如下所示: -

@Controller
@RequestMapping(value = "/groups")
public class GroupsController {
    // mapping #1
    @RequestMapping(method = RequestMethod.GET)
    public String main(@ModelAttribute GroupForm groupForm, Model model) {
        ...
    }

    // mapping #2
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public String changeGroup(@PathVariable Long id, @ModelAttribute GroupForm groupForm, Model model) {
        ...
    }

    // mapping #3
    @RequestMapping(method = RequestMethod.POST)
    public String save(@Valid @ModelAttribute GroupForm groupForm, BindingResult bindingResult, Model model) {
        ...
    }
}

基本上,此页面具有以下功能: -

• 用户访问主页面(/groups GET).
• 用户创建新组(/groups POST)或选择特定组(/groups/1 GET …

我正在尝试构建一个应用程序,它可以列出数据库中的一些值,并在必要时使用Spring 4修改,添加,删除,并且我收到以下错误(仅当我的两个控制器文件中都存在"@Controller"注释时,如果我从其中一个文件中删除注释,但我在控制台中收到一条消息"没有找到映射...在带有名称的dispatcherservlet中......":

我有以下方法:

@RequestMapping(value = "/path/to/{iconId}", params="size={iconSize}", method = RequestMethod.GET)
public void webletIconData(@PathVariable String iconId, @PathVariable String iconSize, HttpServletResponse response) throws IOException {
    // Implementation here
}

我知道如何使用@PathVariable从RequestMapping传递变量"webletId",但是如何从params引用变量"iconSize"？

非常感谢.

我想编写自定义注释,根据注释修改Spring请求或路径参数.例如,而不是这段代码:

@RequestMapping(method = RequestMethod.GET)
public String test(@RequestParam("title") String text) {
   text = text.toUpperCase();
   System.out.println(text);
   return "form";
}

我可以制作注释@UpperCase:

@RequestMapping(method = RequestMethod.GET)
   public String test(@RequestParam("title") @UpperCase String text) {
   System.out.println(text);
   return "form";
}

它是否可能,如果是,我怎么能这样做？

这可能吗？

@Controller
@RequestMapping("/login")
public class LoginController {

    @RequestMapping("/")
    public String loginRoot() {
        return "login";
    }

    @RequestMapping(value="/error", method=RequestMethod.GET)
    public String loginError() {
        return "login-error";
    }

}

我在访问时遇到404错误,localhost:8080/projectname/login但没有localhost:8080/projectname/login/error.

这是我的web.xml项目名称

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<servlet>
    <description></description>
    <servlet-name>projectname</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>projectname</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

我遇到了麻烦！正如我一直在阅读的那样，这种情况的发生是因为它不再被接受。但我该如何解决呢？这是我一直在尝试映射的代码。

@FeignClient(name = "product-service")
@RequestMapping("api/products/")
public interface ProductClient {

    @GetMapping("/{id}")
    ResponseEntity<Product> getProduct(@PathVariable("id") Long id);

    @GetMapping("/{id}/stock")
    ResponseEntity<Product> updateStockProduct(@PathVariable("id") Long id,@RequestParam(name = "quantity", required = true) Integer quantity);
}

预先感谢您的任何建议或解决方案！
