在Action中使用request接收Struts2传递的参数

//通过request接收网页传过来的参数
public String execute(){
//获得HttpServletRequest对象
HttpServletRequest request = (HttpServletRequest)ActionContext.getContext()
.get(org.apache.struts2.StrutsStatics.HTTP_REQUEST);
//获得name参数值
String name = request.getParameter("name");
BookDao bookDao = new BookDao();
//根据name参数值进行模糊查询
Map<String, Integer> booksMap = bookDao.getBooks(name);
//将查询结果放到request域中
request.setAttribute("result", booksMap);
return "result";
}

JSP位置提取相应对象代码：（此处为了方便，于是便在JAVA中写的，思路是一致的）

Map<String, Integer> result = (Map<String, Integer>) request.getAttribute("result");
for (Map.Entry<String, Integer> entry : result.entrySet()) {
System.out.println(entry.getKey()+"\t"+entry.getValue());
}
