java后台接收数据

1、getParameter来获取数据

int userId = Integer.parseInt(this.getgetParameter().getParameter("userId"));        int tieId = Integer.parseInt(this.getRequest().getParameter("tieId"));

2、java前台–》后台的接收：JSP中直接用属性名称来提交数据：
///////后台

@Component(value="tanWeiAction")public class TanWeiAction extends BaseAction{    private Ttanwei tanwei;    public Ttanwei getTanwei() {        return tanwei;    }    public void setTanwei(Ttanwei tanwei) {        this.tanwei = tanwei;    }/**     * 添加摊位     */    public void addTanWei(){        tanwei.setIsValid(true);        tanwei.setBeiZhu("");        tanwei.setCatagoryId(0);        tanwei.setImgUrl("");        tanwei.setTanWeiName("");        int result=this.tanWeiService.addTanWei(tanwei);        if(result>0){            MSG="OK";        }else{            MSG="NO";        }        this.writeJson(MSG);    }

/////前台：

<form id="tanWeiform" method="post" style="margin:0 auto;">                <input id="tanweiId" name="tanwei.id" type="hidden" /> <input                    id="imgUrl" name="tanwei.imgUrl" type="hidden" />                <table style="margin:0 auto">                    <tr>                        <th>商品类别：</th>                        <td><input name="tanwei.catagoryId" id="catagoryTree"                            class="easyui-combotree" data-options="required:true">                        </td>                    </tr>                    <tr>                        <th>摊位名称：</th>                        <td><input name="tanwei.tanWeiName" id="rname"                            class="easyui-validatebox" data-options="required:true">                        </td>                    </tr>                </table>            </form>

3、使用实体类来接收：APP前台发送数据
/////字段名要一致！

Tsignature ts = new Tsignature();        ts.setIsValid(true);        ts.setSignatrue(encodingFunction.getMethodEncoding(user.getSignature()));        ts.setUserId(user.getId());        int i = this.userService.addUserSignature(ts);

////实现：ModelDriven

@Component(value = "userAction")public class UserAction extends BaseAction implements ModelDriven<User> {    private User user = new User();    @Override    public User getModel() {        return user;    }    }
