Httl 和NUTZ的整合

传闻中最快的Httl模板,由于最近想做一个简单ERP开始搭建框架在了解HTTL后 觉得整合HTTL和Nutz

package com.nutzside.common.mvc.view;

import httl.Context;
import httl.web.WebEngine;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.nutz.lang.Files;
import org.nutz.lang.Strings;
import org.nutz.mvc.Mvcs;
import org.nutz.mvc.View;
import org.nutz.mvc.view.AbstractPathView;


public class HTTLView extends AbstractPathView implements View {

private final String ext = ".httl";


public HTTLView(String dest) {
super(dest);


}

/*
* 渲染页面
* 
* @see org.nutz.mvc.View#render(javax.servlet.http.HttpServletRequest,
* javax.servlet.http.HttpServletResponse, java.lang.Object)
* object 只能为Map 否则有无
*/
public void render(HttpServletRequest req, HttpServletResponse resp,
Object obj) throws Throwable {

String path = evalPath(req, obj);
Context context = Context.getContext();
context.put("request", req);
context.put("response", resp);
Enumeration<?> reqs = req.getAttributeNames();
while (reqs.hasMoreElements()) {
String strKey = (String) reqs.nextElement();
context.put(strKey, req.getAttribute(strKey));
}

WebEngine.getEngine()
.getTemplate(getTemplatePath(path, req), req.getLocale())
.render(obj, resp);


}

protected String getTemplatePath(String path, HttpServletRequest request) {

// 空路径，采用默认规则
if (Strings.isBlank(path)) {
path = Mvcs.getRequestPath(request);
path = (path.startsWith("/") ? "" : "/")
+ Files.renameSuffix(path, ext);
}
// 绝对路径 : 以 '/' 开头的路径不增加 '/WEB-INF'
else if (path.charAt(0) == '/') {
if (!path.toLowerCase().endsWith(ext))
path += ext;
}
// 包名形式的路径
else {
path = path.replace('.', '/') + ext;
}

return path;
}
}

package com.nutzside.common.mvc.view;

import org.nutz.ioc.Ioc;
import org.nutz.mvc.View;
import org.nutz.mvc.ViewMaker;

public class HTTLViewMaker implements ViewMaker {


@Override
public View make(Ioc ioc, String type, String value) {
if("httl".equalsIgnoreCase(type)){
return new HTTLView(value);
}
return null;
}



}

@At
@Ok("httl:pagemain.main_layout")
@Fail("redirect:/index.jsp")
public Object main(HttpServletResponse response) throws IOException {
