test/100/200/300 실행시에..
콘솔창에 값은 잘 출력이 되는데요... result.jsp 경로가 이상하게 나옵니다..(그 전까지는 잘 나왔구요...)
에러:메시지 파일 [/test5/100/200/WEB-INF/views/result.jsp]을(를) 찾을 수 없습니다.
<==경로가 왜 이렇게 바뀌는지요??? ...
1. index.jsp
<a href="test5/100/200/300">test5</a>
2. TestController
@GetMapping("/test5/{data1}/{data2}/{data3}")
public String test5(@PathVariable int data1,
@PathVariable int data2,
@PathVariable int data3) {
System.out.println("data1 : " + data1);
System.out.println("data2 : " + data2);
System.out.println("data3 : " + data3);
return "result";
}
------------------------------------------------
이 전까지는 모든 예제 잘 출력되었구요.....
아시는 분은 답변 주시면 감사하겠습니다;;;;
