Scalate模板大小限制爲64k？

嘗試包括一堆HTML的是SSP模板，我有以下異常：Scalate模板大小限制爲64k？

看着scala.tools.asm.ByteVector我發現以下幾點：

public ByteVector putUTF8(String s) { 
    int charLength = s.length(); 
    if(charLength > '\uffff') { 
     throw new IllegalArgumentException(); 
    } else { ....

如果模板尺寸更比65536字節，它無法編譯此模板。如何將大的一塊純HTML包含到SSP模板中？ Include似乎只適用於模板文件。我應該手動加載和輸出模板中的HTML文件？有沒有更好的方法？

你找到一個解決辦法？ –

@FatihDonmez請看我的答案 –

看來這是一個固有的限制。

解決方法：手動讀取文件，並輸出到模板（是的，這是醜陋的，但工程）：

<% include("header.ssp") %> 

<%@ val book:Integer %> 

<% val bookHtml = "./public/books/" + "book_" + book + ".html"%> 
<% val source = scala.io.Source.fromFile(bookHtml) 
val lines = try source.mkString finally source.close() 
%> 

${unescape(lines)} 

<% include("footer.ssp") %>

Yeap，有一些調試，我看到這是jvm的限制。 Scalate模板主要是生成類中的字符串文字。限制來自; CONSTANT_Utf8_info {u1標籤; u2長度; u1 bytes [length]; }。因此，我們將其更改爲Freemarker而不是Scalate :) –

Scalate模板大小限制爲64k？
