jsp超链接传值到后台

Struts中多个超链接调用同样的action，只是返回结果不同的处理方法
jsp:

<a href="getColor.action?color="blue">blue</a><a href="getColor.action?color="red">red</a>

Action:

public String getColor(){  ...  ...  String hint = "this is color";  ActionContext.getContext().put("hint",hint);  if(color.equal("blue")){    return "blue color";  }else{    return "red color";  } }
