我的數據結構是這樣的。從MongoDB獲取文檔
{
"Item" : {
"CreateTimestamp" : {
"@value" : "2012-12-31 01:48:24"
},
"EventList" : {
"Event" : [ {
"@eventId" : "5",
"@eventName" : "Bullets"
}, {
"@eventId" : "33",
"@eventName" : "ItemMaster"
}]
},
"DirNumber" : {
"@value" : "10713024"
},
"MNumber" : {
"@value" : "10713024"
}
}}}
我想只使用'DirNumber'來獲取數據。我想在java中查詢請幫
