不错 。。终于等到你！！

eclipse 代码生成报错运行方式：java application 添加 -i dic_country -p cn.wizzer.modules.back.sys -u /private/sys 参数
code.json

var ioc={
     dataSource : {
        type : "org.nutz.dao.impl.SimpleDataSource",
        fields : {
                url : "jdbc:mysql://121*****.120:3306/***",
                username : "****",
                password : "123456"
        }
    },
    loader:{
    //根据实体生成代码
    //type:'cn.enilu.common.code.EntityDescLoader'
    //根据表结构生成代码
      type:'cn.enilu.common.code.TableDescLoader'
    }
}

修改下dao.json 就好了

	conf : {
			type : "org.nutz.ioc.impl.PropertiesProxy",
			fields : {
				paths : ["config/custom/"]
			}
		},
	    dataSource : {
			factory : "$conf#make",
			args : ["com.alibaba.druid.pool.DruidDataSource", "db."],
	        type : "com.alibaba.druid.pool.DruidDataSource",
	        events : {
	        	create : "init",
	            depose : 'close'
	        }
	    },
		dao : {
			type : "org.nutz.dao.impl.NutDao",
			args : [{refer:"dataSource"}],
			fields : {
				executor : {refer:"cacheExecutor"}
			}
		},

eclipse的生成代码不全！ 两个循环没出来！

  <thead>
                    <tr>
                            <th>操作</th>
                    </tr>
 </thead>

 "columns": [
 ],

@enilu 我用实体生成可以的。谢谢了
