java里面时间类型转换成json数据就成这样啦

"modifyTime":{"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')
}
