处理程序方法没有得到考虑

Question

我有以下代码

@Controller
@RequestMapping("/xyz")
public class MyController {

@RequestMapping(method = RequestMethod.GET, value = "/abc")
@SuppressWarnings("unchecked")
@ResponseBody   
public void myMethod(String pqr) {
    ....
    ....
}
....
....

我正在制作一个AJAX请求/ contextname / xyz / abc

但是上面声明的处理程序方法没有被考虑，我得到以下错误

DEBUG o.s.web.servlet.DispatcherServlet - DispatcherServlet with name           
'contextname' processing GET request for    
[http://mydomain:8085/contextname/xyz/abc]

00:22:32.867 [http-nio-8080-exec-1] DEBUG

path /abc

mapping found for HTTP request with URI   
[http://mydomain:8085/contextname/xyz/abc] in DispatcherServlet with name  
'contextname'

有什么建议吗？

Answer 1

删除String pqr参数，spring不知道该注入什么。

Answer 2

将方法的签名更改为...

public void myMethod(@RequestParam(required=false) String pqr) 

...如果您想偶尔发送该参数，并且您的方法不依赖于它。

Spring并不知道传递给方法的值。
