404 Request Resource not found - spring

Question

I am using Spring Framework with restful web services, and I am trying to create an API with restful service and use a get method. I have created a method and I'm trying to have it return a string, but instead I get a 404 error - requested resources not found. Please see my code below:
#RestController
#RequestMapping("/test")
public class AreaController {
public RestResponse find(#PathVariable String name, ModelMap model) {
model.addAttribute("movie", name);
return "list";
}
}
I am using: localhosr:8080/MyProject/wangdu

Answer 1

This error occurs because you forgot to add
#RequestMapping(value = "/{name}", method = RequestMethod.GET) before your find method:
#RestController
#RequestMapping("/test")
public class AreaController {
#RequestMapping(value = "/{name}", method = RequestMethod.GET)
public RestResponse find(#PathVariable String name, ModelMap model) {
model.addAttribute("movie", name);
return "list";
}
}

Answer 2

Please make sure about this:
The value that the find method is returning is a String with the value "list" and the find method declaration is waiting for a RestResponse object
For example if I have a RestResponse object like this:
public class RestResponse {
private String value;
public RestResponse(String value){
this.value=value;
}
public String getValue(){
return this.value;
}
}
Then try to return the value in this way:
public RestResponse find(#PathVariable String name, ModelMap model) {
model.addAttribute("movie", name);
return new RestResponse("list");
}
Verify that the method has #RequestMapping annotation with the value that your expect from the url
#RequestMapping(method = RequestMethod.GET, value = "/{name}")
By default the proper way to call the rest resource is by the #RequestMapping value that you set at the #RestController level (#RequestMapping("/test")), in this case could be: http://localhost:8080/test/myValue
If you need to use a different context path then you can change it on the application.properties (for spring boot)
server.contextPath=/MyProject/wangdu
In that case you can call the api like this:
http://localhost:8080/MyProject/wangdu/test/myValue
Here is the complete code for this alternative:
#RestController
#RequestMapping("/test")
public class AreaController {
#RequestMapping(method = RequestMethod.GET, value = "/{name}")
public RestResponse find(#PathVariable String name, ModelMap model) {
model.addAttribute("movie", name);
return new RestResponse("list");
}
