自定义viewMarker如下：

@Override
	public View make(Ioc ioc, String type, String value) {
		
		log.info("type:" + type);
		log.info("value:" + value);
		if(type.equals(ADMIN_JSON)) {
			if (StringUtils.isEmpty(value)) {
	                return new AdminView(JsonFormat.nice()).setJsonp(true);
            }else {
            	// 除高级的json format定义之外,也支持简单的缩写
                if (value.charAt(0) == '{'){
                	log.info("=======================");
                    return new AdminView(Json.fromJson(JsonFormat.class, value)).setJsonp(true);
                }else if ("nice".equals(value))
                    return new AdminView(JsonFormat.nice()).setJsonp(true);
                else if ("forlook".equals(value))
                    return new AdminView(JsonFormat.forLook()).setJsonp(true);
                else if ("full".equals(value))
                    return new AdminView(JsonFormat.full()).setJsonp(true);
                else if ("compact".equals(value))
                    return new AdminView(JsonFormat.compact()).setJsonp(true);
                else if ("tidy".equals(value))
                    return new AdminView(JsonFormat.tidy()).setJsonp(true);
                else
                    throw new IllegalArgumentException("unkown json view format : " + value);
            }
		}
		return null;
	}

Module入口如下：

@At("/screen-agent")
@Ok("adminJson:{dateFormat:'yyyyMMdd'}")

就是使用自己的jsonview，继承了utf8jsonView，想使用原本的format

@Views写了没

MainModule

@SetupBy(value = MainModule.class)
@IocBy(type = ComboIocProvider.class, args = { "*js", "ioc.js", "*anno", "com.tohours.superplanner", "*tx", "*quartz" })
@Views(value = {SpViewMaker.class, DefaultViewMaker.class})
@ChainBy(args = { "chain.js" })

debug一下 if(type.equals(ADMIN_JSON)) { 这一行

看上去只是type.equals没对上

总的viewmarker:

package com.tohours.superplanner.view;

import org.apache.commons.lang.StringUtils;
import org.apache.log4j.Logger;
import org.nutz.ioc.Ioc;
import org.nutz.json.Json;
import org.nutz.json.JsonFormat;
import org.nutz.mvc.View;
import org.nutz.mvc.ViewMaker;

public class SpViewMaker implements ViewMaker{

	private static final Logger log = Logger.getLogger(SpViewMaker.class);
	
	private final String ADMIN_JSON = "adminJson";
	
	public SpViewMaker() {
		super();
	}
	
	@Override
	public View make(Ioc ioc, String type, String value) {
		
		log.info("type:" + type);
		log.info("value:" + value);
		if(type.equals(ADMIN_JSON)) {
			if (StringUtils.isEmpty(value)) {
	                return new AdminView(JsonFormat.nice()).setJsonp(true);
            }else {
            	// 除高级的json format定义之外,也支持简单的缩写
                if (value.charAt(0) == '{'){
                	log.info("=======================");
                    return new AdminView(Json.fromJson(JsonFormat.class, value)).setJsonp(true);
                }else if ("nice".equals(value))
                    return new AdminView(JsonFormat.nice()).setJsonp(true);
                else if ("forlook".equals(value))
                    return new AdminView(JsonFormat.forLook()).setJsonp(true);
                else if ("full".equals(value))
                    return new AdminView(JsonFormat.full()).setJsonp(true);
                else if ("compact".equals(value))
                    return new AdminView(JsonFormat.compact()).setJsonp(true);
                else if ("tidy".equals(value))
                    return new AdminView(JsonFormat.tidy()).setJsonp(true);
                else
                    throw new IllegalArgumentException("unkown json view format : " + value);
            }
		}
		return null;
	}
	

}

好像是的，谢谢

"adminJson" -- "adminjson"

大小写对不上

低级错误，谢谢

不对哈，我Module里面用的是

@Ok("adminJson:{dateFormat:'yyyyMMdd'}")

为什么在启动的时候成了adminjson

是不是框架装成了小写的，我需要做一下转换是吧

翻了翻代码，ViewZone里面把type转小写了
