我遇到了非常奇怪的错误,当我尝试访问它时,我收到的请求为空。我总是使用相同的方法来获取它,但现在我遇到了这个错误。
我的动作如下所示:
package com.deveto.struts.actions;
import com.deveto.hibernate.mappings.Slider;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.util.ServletContextAware;
/**

*/
public class ContentAction extends ActionSupport implements ServletContextAware {
HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
HttpServletResponse response = (HttpServletResponse) ActionContext.getContext().get(ServletActionContext.HTTP_RESPONSE);
ActionContext ac = ActionContext.getContext();
ServletContext sc = (ServletContext) ac.get(ServletActionContext.SERVLET_CONTEXT);
@Override
public String execute() throws Exception {
System.out.println("request: " + request);
return SUCCESS;
}
public ActionContext getAc() {
return ac;
}
public void setAc(ActionContext ac) {
this.ac = ac;
}
public HttpServletRequest getRequest() {
return request;
}
public void setRequest(HttpServletRequest request) {
this.request = request;
}
public HttpServletResponse getResponse() {
return response;
}
public void setResponse(HttpServletResponse response) {
this.response = response;
}
public ServletContext getSc() {
return sc;
}
public void setSc(ServletContext sc) {
this.sc = sc;
}
public void setServletContext(ServletContext sc) {
this.sc = sc;
}
}
而现在我什么也做不了,请求总是空的
request: null
