ssh框架下 写简单的hql语句

标签（空格分隔）： 简单的hql 重要的在dao层 ！！！

---

• action

@Autowired
	private FlowActiveSrv	  flowActiveSrv;
	private Integer			  pageSize;
	
private String findUserId() {
	UserSession userSession = (UserSession) session.get("UserSession");
	return userSession.getId();
}

//此处返回的是一个List<FlowActive>集合
public void findMyApply() {
	String userId = this.findUserId();
	List<FlowActive> list =this.flowActiveSrv.findMyApply(userId, pageSize);
	this.sendResponseMsg(list);
}

//处理一下
protected void sendResponseMsg(Object src) {
	final Gson g = new GsonBuilder().setDateFormat(DateFormat.DateTime.getFormat()).create();
	this.sendResponseMsg(g.toJson(src));
}

• serviseImpl

@Autowired
private FlowActiveDao flowActiveDao;

@Override
public List<FlowActive> findMyApply(String userId,int pageSize) {
	return flowActiveDao.findMyApply(userId,pageSize);
}

• daoImpl

@Override
public List<FlowActive> findMyApply(String userId,int pageSize) {
	if (StringUtils.isBlank(userId)) {
		return Lists.newArrayList();
	}
	Map<String, Object> values = new HashMap<String, Object>();
	String hql = "FROM FlowActive where step != 99 and applyPersonId = :applyPersonId order by createTime desc";
	values.put("applyPersonId", userId);
	Query query = createHqlQuery(hql, values);
	query.setFirstResult(0);
	query.setMaxResults(pageSize);
	@SuppressWarnings("unchecked")
	List<FlowActive> list = query.list();
	return list.isEmpty() ? Lists.newArrayList() : list;
}

• js 调用方法后台 填充模板

//这里使用的模板填充　template.js
// http://www.cnblogs.com/shiyou00/p/6841801.html
//http://www.jq22.com/jquery-info1097

function loadApplyData() {
    $.post(applyAction + "!findMyApply", { pageSize: 5 }, function(data) {
        var html = template("gridApplyTpl", { 'results': data });
        $("#gridApplyBody").html(html);
    }, "json")
}

• 以上代码尚未贴出get,set方法，接口等
