aware接口注入,即实现ServletRequestAware接口(此方式最为麻烦)
public class Demo2ServletAction extends ActionSupport implements ServletRequestAware{
private HttpServletRequest request;
@Override
public String execute() throws Exception {
request.setAttribute("gf", "request_aware");
return SUCCESS;
}
@Override
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}
}
public class Demo2ServletAction extends ActionSupport implements ServletRequestAware{
private HttpServletRequest request;
@Override
public String execute() throws Exception {
request.setAttribute("gf", "request_aware");
return SUCCESS;
}
@Override
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}
}
