jsp request.getAttribute 中如何取值？

推荐回答（4个）

回答1：

jsp request.getAttribute是通过key来获取value的。
比如
SelRs rsSr=(SelRs)request.getAttribute("oaSr");
String dbType=(String)request.getAttribute(WebKeys.DbType);
这两句话是同一个意思..
SelRs rsSr=(SelRs)request.getAttribute("oaSr");是获得request.setAttribute("oaSr",对象);中的对象;而String dbType=(String)request.getAttribute(WebKeys.DbType); 是获得request.setAttribute("**","值");**和WebKeys.DbType的值一样;

回答2：

request.setAttribute（"allhead",字符串数组）
request.setAttribute（"allhead",字符串二维数组）

你已经取出来了在storName和allbdoy中

回答3：

先set才能get啊！
request.setAttribute（"allhead",字符串数组);之后再
request.getAttribute（"allhead",字符串数组);

回答4：

赋值后取键值就可以了
