初始化页面微博内容

//获取微博内容(初始化页面)

public static void getInit ( String uid ) throws IOException{

//获取连接

Connection connection = ConnectionFactory .createConnection ( configuration );

//获取表对象(2个)

Table inboxTable= connection . getTable ( TableName . valueor ( Constant . IBOn );

Table contTable =connection . getTable ( TableNane . valueOr ( Constant . CoNTENTn );

//获取收件箱表数据

Get get = new Get( Bytes . toBytes ( uid ));//收件箱表get对象

Result result = inboxTable . get ( get );//设置获取最大版本的数据

Result result = inboxTable . get ( get );

ArrayList < Get > gets ＂ new ArrayList <>();

Cell[] cells = result .rawCells0:

//遍历返回内容并将其封装成内容的 get 对 象

for ( Cell cell : cells ){

Get contGet = new Get ( CellUtil . clonelalue(cell)):

gets . add ( eontGet );

//根据收件箱获取值去往内容表获取微博内容

Result [] results = contTable . get ( gets );

for ( Result result1: results ){

Ce11[]cells1=result1.rawCells();

//遍历打印

for ( Cell cel1:cells1){

System . out . println (" RK :”+ Bytes . toString (CellUtil. cloneRoa (cel1))

+＂, Content ;”+ Bytes . toString (Cel1Util. clonelalue (cel1)))

}

}

//关闭资源

inboxTable .close0: contTable .close（）；

connection . close (）；

Connection. Close();
