[SPRING] 봄 JSP 페이지가 평가되지 않음
SPRING봄 JSP 페이지가 평가되지 않음
Spring 3.1.0에서 흥미로운 문제가있다. JSP 페이지의 EL 평가가 없습니다. 뷰 해결 과정을 디버깅했으며 JstlView가 사용되고 Jstl 라이브러리가 감지되었습니다. 그러나, 나의 JSP 페이지는
<%="Hello World!"%>
여기에이 문제에 대한 많은 참고 자료가 있으며, 그 중 어느 것도 저에게 효과적이지 않았습니다.
JSP 페이지에서 렌더링되지 않은 스크립트 태그 (Spring + Tiles + JSPX 사용) Spring과 JSP EL이 처리되지 않음
상단에서, 여기 내 설정이야;
을 포함한다.

일부 freemarker 물건 및 거기에 너무 REST로 ContentNegotiatingViewResolver 사용하고 있습니다.
제어 장치
@RequestMapping("/")
@Controller
public class RootResource extends AbstractResource {
...abridged...
@RequestMapping(value="/jsp", method = RequestMethod.GET, produces = "text/html")
public String getJSP(final Model m) {
return "example";
}
}
example.jsp
<%@ page isScriptingEnabled="true" isELIgnored="false" %>
<html>
<head>
<title>Hello World JSP Page.</title>
</head>
<body>
<font size="10"><%="Hello World!"%></font>
</body>
</html>
내 컨트롤러에서 뷰 이름으로 "example"을 반환하고 올바른 WEB-INF / jsp / example.jsp로 로그하는 로그에서 확인할 수 있습니다.

따라서 모든 것이 정상적으로 보입니다. JSP 페이지가 정확하게 평가되지 않습니다.
example.jsp는 다음과 같이 보입니다.
<%@ page isScriptingEnabled="true" isELIgnored="false" %> <%="Hello World!"%>
webapp을 실행하기 위해 Maven jetty 6 플러그인을 사용하고 있습니다.
나는 무언가 간단한 것을 놓치고있을 것이라고 확신한다. 아마도 "너무 오랫동안 그것을 보았다"문제 중 하나 일 것이다.
당신이 줄 수있는 포인터를 가져 주셔서 감사합니다.
업데이트 1 - 방금 스프링 서블릿 매핑을 / *에서 / spring / *로 변경했습니다. 이제는 작동합니다. 그래서 스프링 서블릿 주위에 / *에 맵핑 된 세부 사항이 있습니다.
해결법
-
==============================
1.절대적으로 "너무 오랫동안 보았다"는 경우입니다.
절대적으로 "너무 오랫동안 보았다"는 경우입니다.
스프링 서블릿은 기본 서블릿이어야합니다. 즉 /와 /에 매핑되지 않습니다.
