struts2.2-jquery-plugin学习Action的写法（五）
(一）首先关于数据显示（分页查询）的Action的写法：
package com.newsicom.jxc.basicInfo.goodsUnits.action;import java.util.List;import net.sf.json.JSONArray;import net.sf.json.JSONObject;import net.sf.json.JSONSerializer;import com.newsicom.jxc.basicInfo.common.model.GoodsUnits;import com.newsicom.jxc.basicInfo.common.model.ProductUnits;import com.newsicom.jxc.basicInfo.common.util.PageBean;import com.newsicom.jxc.basicInfo.goodsUnits.dao.IproductUnitsDAO;import com.newsicom.jxc.basicInfo.goodsUnits.service.IGoodsUnitsService;import com.opensymphony.xwork2.ActionSupport;public class GoodsUnitsAction extends ActionSupport{//此处的goodsUnitsService不能有get方法IGoodsUnitsService<GoodsUnits> goodsUnitsService;private String filters;//多条件查询private List<GoodsUnits> gridModel;//表格中的数据;private Integer rows=10;//页大小，ajax请求参数提供，对应表格中的rowNum;private Integer page=1;//当前页，ajax请求提供private Integer total=0;//总页数private Integer records=0;//总记录表格中使用public List<GoodsUnits> getGridModel() {return gridModel;}public void setGridModel(List<GoodsUnits> gridModel) {this.gridModel = gridModel;}public void setGoodsUnitsService(IGoodsUnitsService<GoodsUnits> goodsUnitsService) {this.goodsUnitsService = goodsUnitsService;}public Integer getRows() {return rows;}public void setRows(Integer rows) {this.rows = rows;}public Integer getPage() {return page;}public void setPage(Integer page) {this.page = page;}public Integer getTotal() {return total;}public void setTotal(Integer total) {this.total = total;}public Integer getRecords() {return records;}public void setRecords(Integer records) {this.records = records;}public void setFilters(String filters) {this.filters = filters;}//转换['eq','ne','lt','le','gt','ge','bw','bn','in','ni','ew','en','cn','nc']public static String switchSign(String op){if("eq".equals(op)){return "=";}else if("ne".equals(op)){return "<>";}else if("lt".equals(op)){return "<";}else if("gt".equals(op)){return ">";}elsereturn "like %";}public String execute() throws Exception{if(this.filters!=null){JSONObject jsonFilter = (JSONObject) JSONSerializer.toJSON( filters );String groupOp = jsonFilter.getString("groupOp");System.out.println("groupOp :" + groupOp);JSONArray rules = jsonFilter.getJSONArray("rules");int rulesCount = JSONArray.getDimensions(rules)[0];System.out.println("Count Rules :" + rulesCount);//查询语句String sql="from ProductUnits p where ";if("AND".equals(groupOp)){for (int i = 0; i < rulesCount; i++) {JSONObject rule = rules.getJSONObject(i);System.out.println("field :" + rule.getString("field"));System.out.println("op :" + rule.getString("op"));System.out.println("data :" + rule.getString("data"));if("id".equals(rule.getString("field"))){sql=sql+"p."+rule.getString("field")+switchSign(rule.getString("op"))+rule.getString("data");}else{sql=sql+"p."+rule.getString("field")+switchSign(rule.getString("op"))+"'"+rule.getString("data")+"'";}sql=sql+" and p."+rule.getString("field")+switchSign(rule.getString("op"))+"'"+rule.getString("data")+"'";}}else{for (int i = 0; i < rulesCount; i++) {JSONObject rule = rules.getJSONObject(i);System.out.println("field :" + rule.getString("field"));System.out.println("op :" + rule.getString("op"));System.out.println("data :" + rule.getString("data"));if("id".equals(rule.getString("field"))){sql=sql+" p."+rule.getString("field")+switchSign(rule.getString("op"))+rule.getString("data");}else{sql=" or "+sql+rule.getString("field")+switchSign(rule.getString("op"))+"'"+rule.getString("data")+"'";}}}System.out.println(sql);PageBean<GoodsUnits> pb=this.goodsUnitsService.getT(sql,page, rows);total=pb.getTotalPage();records=pb.getTotal();gridModel=pb.getT();}else{PageBean<GoodsUnits> pb=this.goodsUnitsService.getT("from GoodsUnits",page, rows);total=pb.getTotalPage();System.out.println(total);records=pb.getTotal();System.out.println(records);gridModel=pb.getT();}return SUCCESS;}}??(二)关于增,删,改,编辑,的操作的Action:
package com.newsicom.jxc.basicInfo.goodsUnits.action;import java.util.StringTokenizer;import com.newsicom.jxc.basicInfo.common.model.GoodsUnits;import com.newsicom.jxc.basicInfo.common.model.ProductUnits;import com.newsicom.jxc.basicInfo.goodsUnits.dao.IproductUnitsDAO;import com.newsicom.jxc.basicInfo.goodsUnits.service.IGoodsUnitsService;import com.opensymphony.xwork2.ActionSupport;public class EditGoodsUnitsAction extends ActionSupport{//此处的googsUnitsService不能有get方法：private IGoodsUnitsService<GoodsUnits> goodsUnitsService;private String oper;// add或del或editprivate String id;private String cd;//编码private String name;//名称private String byname;//别名private String memCode;//助记符private String memo;//备注public String getOper() {return oper;}public void setOper(String oper) {this.oper = oper;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getCd() {return cd;}public void setCd(String cd) {this.cd = cd;}public String getByname() {return byname;}public void setByname(String byname) {this.byname = byname;}public String getMemCode() {return memCode;}public void setMemCode(String memCode) {this.memCode = memCode;}public String getMemo() {return memo;}public void setMemo(String memo) {this.memo = memo;}public void setGoodsUnitsService(IGoodsUnitsService<GoodsUnits> goodsUnitsService) {this.goodsUnitsService = goodsUnitsService;}@Overridepublic String execute() throws Exception {if ("add".equals(oper)) {this.add();} else if ("del".equals(oper)) {this.delete();} else if (oper.equalsIgnoreCase("edit")) {this.edit();}return null;}private void add() {GoodsUnits goodsUnits = new GoodsUnits();goodsUnits.setCd(cd);goodsUnits.setName(name);goodsUnits.setByname(byname);goodsUnits.setMemCode(memCode);goodsUnits.setMemo(this.memo);goodsUnitsService.create(goodsUnits);}private void delete() {StringTokenizer ids = new StringTokenizer(id, ",");while (ids.hasMoreTokens()) {int removeId = Integer.parseInt(ids.nextToken());Integer i = new Integer(removeId);goodsUnitsService.deleteByID(i);}}private void edit() {Integer integer = Integer.parseInt(id);GoodsUnits goodsUnits = (GoodsUnits) goodsUnitsService.findById(GoodsUnits.class, integer);goodsUnits.setCd(cd);goodsUnits.setName(name);goodsUnits.setByname(byname);goodsUnits.setMemCode(memCode);goodsUnits.setMemo(this.memo);goodsUnitsService.update(goodsUnits);}}?关于Action的配置请查看配置文件那篇文章.
