json时间格式转为ext

java里面时间类型转换成json数据就成这样啦。（注意我画红的地方）"createTime":{"date":30,"day":3,"hours":15,"minutes":14,"month":3,"nanos":0,"seconds":38,"time":1209539678000,"timezoneOffset":-480,"year":108}在gridpanel里面就会显示成[object,object]在store里面这样写{name : 'createTime',type : 'date',mapping : 'createTime.time',dateFormat : 'time'}在ColumnModel里面这样写{header : "创建时间",sortable : true,dataIndex : 'createTime',renderer : Ext.util.Format.dateRenderer('Y-m-d H:i:s')}就会显示成你想要的格式不用在后台处理成字符串啦。
