Why rett Template.put（）throws「Http Client ErrrorException：404 Not Found」

 
I make a put request

RestTemplate restTemplate = new RestTemplate();
restTemplate.put(new URI("http://localhost:8080/test"), dto);

which success fully hith the rest endpoint

@RequestMapping(value = "/test", method=RequestMethod.PUT)
public void test123(@RequestBody DTO dto) {
    System.out.println("phone:"+dto.getPhone()); 
}

but the「put」method on the client throws exception、even though the server is hit succelly and I don't expect return value.

Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 404 Not Found

接続パスが正しいかどうかを確認します。
