一：方式一：通过request来获取，首先让action实现ServletRequestAware接口，然后通过request来获取提交的参数，代码如下:

package cn.gov.csrc.flight.action;import java.util.HashMap;
import java.util.List;
import java.util.Map;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.json.annotations.JSON;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;import cn.gov.csrc.base.action.BaseAction;
import cn.gov.csrc.cms.model.UserInfo;
import cn.gov.csrc.cms.service.UserService;
import cn.gov.csrc.flight.model.Flgtinfo_D;
import cn.gov.csrc.flight.service.FlgtinfodService;@Controller
@ParentPackage("json-default") 
@Scope("prototype")
public class FlgtinfodAction extends BaseAction<Flgtinfo_D> implements ServletRequestAware{private static final long serialVersionUID = 1L;private FlgtinfodService flgtinfodService;private Map<String, Object> dataMap;HttpServletRequest request;public FlgtinfodAction(){dataMap = new HashMap<String, Object>();}@Resourcepublic void setFlgtinfodService(FlgtinfodService flgtinfodService) {this.flgtinfodService = flgtinfodService;}@Action(value = "FlgtinfodAction_detail", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })public String detail(){dataMap.clear(); //查询出港详情(根据用户id，列表到详情的唯一编号)String id = this.request.getParameter("id");Flgtinfo_D flgtinfo_D = flgtinfodService.getEntity(id);String airline2 = flgtinfo_D.getAirline();// 出港详情放入到dataMap中dataMap.put("flgtinfo_D", flgtinfo_D);// 放入一个是否操作成功的标识 dataMap.put("success", true);return "success";}public Map<String, Object> getDataMap() {return dataMap;}@Overridepublic void setServletRequest(HttpServletRequest request) {this.request = request;}}

二：方式二，直接在action里面写你要提交的参数，然后提供set，get方法，代码如下：

package cn.gov.csrc.flight.action;import java.util.HashMap;
import java.util.List;
import java.util.Map;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.json.annotations.JSON;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;import cn.gov.csrc.base.action.BaseAction;
import cn.gov.csrc.cms.model.UserInfo;
import cn.gov.csrc.cms.service.UserService;
import cn.gov.csrc.flight.model.Flgtinfo_D;
import cn.gov.csrc.flight.service.FlgtinfodService;@Controller
@ParentPackage("json-default") 
@Scope("prototype")
public class FlgtinfodAction extends BaseAction<Flgtinfo_D>{private static final long serialVersionUID = 1L;private Integer id; // 列表到详情的唯一标识private FlgtinfodService flgtinfodService;private Map<String, Object> dataMap;public FlgtinfodAction(){dataMap = new HashMap<String, Object>();}@Resourcepublic void setFlgtinfodService(FlgtinfodService flgtinfodService) {this.flgtinfodService = flgtinfodService;}@Action(value = "FlgtinfodAction_find", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })public String find() {dataMap.clear(); //查询出港信息List<Flgtinfo_D> list = flgtinfodService.findAllFlgtinFods();// 出港信息放入到dataMap中dataMap.put("list", list);// 放入一个是否操作成功的标识 dataMap.put("success", true);return "success";}@Action(value = "FlgtinfodAction_detail", results = { @Result(name = "success", type = "json", params = {"root", "dataMap" }) })public String detail(){dataMap.clear(); //查询出港详情(根据用户id，列表到详情的唯一编号)id = model.getId();Flgtinfo_D flgtinfo_D = flgtinfodService.getEntity(id);String airline2 = flgtinfo_D.getAirline();// 出港详情放入到dataMap中dataMap.put("flgtinfo_D", flgtinfo_D);// 放入一个是否操作成功的标识 dataMap.put("success", true);return "success";}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public Map<String, Object> getDataMap() {return dataMap;}}
