我是maven / spring的新手,我正在努力弄清楚为什么我会遇到这些错误。网上有很多这样的问题,但是在尝试使用可用的解决方案后,我仍然无法解决我的错误:
May 17, 2016 7:01:47 PM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/example/helloWorld/meow] in DispatcherServlet with name 'mvc-dispatcher'
我的设置如下:Apache Tomcat( 我正在尝试创建一个REST API,允许我上传和下载文件,以及通过REST调用来回发送消息。我目前定义了3个REST端点:
现在,只有第1和第2个调用工作,而3个是导致上述错误的原因。
我正在使用终端来ping每个端点。以下是我对测试1和2进行调用的示例:
curl -X GET localhost:8080/example/helloWorld/hello
这很有效。
但是,当我执行此命令时,我得到404响应,以及上面的错误:
curl -X POST localhost:8080/example/helloWorld/meow -d "{'body':1234}"
我很确定我发送的数据是正确的,但还没有达到目标,因为当我检查我的服务器的catalina.out文件时,我看到上面提到的错误,意思是我甚至无法调试我的请求,因为URI不起作用。
有一个前端定义,但我不关心它,因为我只需要REST调用。
这是我的控制器:
...imports...
@Controller
@RequestMapping("/helloWorld")
public class HelloWorldController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String hello(ModelMap model) {
model.addAttribute("msg", "JCG Hello World!");
System.out.println(new Date().toString() + "testPrint: in hello");
return "helloWorld";
}
@RequestMapping(value = "/displayMessage/{msg}", method = RequestMethod.GET)
public String displayMessage(@PathVariable String msg, ModelMap model) {
model.addAttribute("msg", msg);
System.out.println(new Date().toString() + "testPrint: "+msg);
return "helloWorld";
}
@RequestMapping(value = "/meow", method = RequestMethod.POST)
// @ResponseBody
public ResponseEntity<Boolean> saveData(HttpServletRequest request,
HttpServletResponse response, Model model) {
String jsonString = request.getParameter("json");
System.out.println(new Date().toString() + "testPrint: " + jsonString);
return null;
}
}

另外,我有这条线:
在包的末尾有一个*,因为我读了一个解决方案,说添加*修复了问题,但它没有修复我的,所以我还没有把它拿出来。但无论有没有它都无效。
答案 0 :(得分:0)
我想你可能会在命令中错过StackInterface
,试试吧;)
