struts2获取response

Struts2获取response的两种方式：

第一种方式：使用OgnlValueStack 对象获取：

public class DepartmentAction extends BaseAction implements RequestAware{

private Map request;
private HttpServletResponse response;

OgnlValueStack stack = (OgnlValueStack) request.get("struts.valueStack");
response = (HttpServletResponse) stack.getContext().get(StrutsStatics.HTTP_RESPONSE);

System.out.println(response );

public void setResponse(HttpServletResponse response) {
this.response = response;
}

public void setRequest(Map request) {
this.request = request;
}

}

第二种方式：直接使用ServletActionContext对象获取，超简单：

public class DepartmentAction extends BaseAction{

HttpServletResponse response = ServletActionContext.getResponse();

System.out.println(response );

}
