나는 java.lang.OutOfMemoryError: Java heap space을 얻고 있으며 그것을 피하는 방법을 모르겠습니다. 나는 기본적으로 소켓 버퍼라고 생각했던 것에 대해 쓰고있다. 나는 그것이 javax.servlet.jsp.JspWriter라고 생각한다.내 JSF 코드가 "java.lang.OutOfMemoryError : Java heap space"를 얻는 방법은 무엇입니까?
그러나 매우 큰 HTML 파일 인 ~ 70 만 줄을 쓸 경우 java.lang.OutOfMemoryError: Java heap space이됩니다. 프레임 워크가 소켓에 플러시되지 않는 이유를 혼란스러워했습니다. (Marsha, Marsha, Marsha) 제쳐두고, 버퍼를 자라기보다는 소켓에 플러시 할 수 있습니까?
JSF 1.1을 사용하고 있습니다.
참고,이 web.xml 파일을 추가하려고 않았다
<context-param>
<param-name>facelets.BUFFER_SIZE</param-name>
<param-value>500000</param-value>
</context-param>
아무것도 변경하는 것 같지 않았어요. 여기
<html>
<f:view>
<head>
<title>Test</title>
</head>
<body id="page_body"
<h:form id="form">
<%
String s;
for (int i = 0; i < rowCount; i++) {
s = data.get(i);
out.println(s);
//flush after on every thousandths row.
//if(i%1000==1)
// out.flush();
} // for loop
%>
</h:form>
</body>
</f:view>
</html>

여기에 내 코드 샘플입니다. 압력, 롤. JSF 질문의 절반 정도를 대답합니다.

을 내보내십시오. 작은 파일은 문제없이 작동한다는 것을 의미합니다. 그 맞습니까? – kolossus
@koloossus 네, 잘 작동합니다. BodyContentImpl이 소켓에 쓰는 것이 아니라 char [] cp에 쓰는 것 같습니다. –
아무 것도 다른 출력에 임의로 쓰려고하지 않습니다. 힙을 압도하는 데이터 양의 간단한 경우입니다. 미세 조정을 위해 힙 크기 설정을 수정하십시오 – kolossus
