dao 中自定义返回实体

1）java对象

public class SplashItem {
	public String	url;
	public long		enabledTime;
	public long		splashId;
	public String	eTag;

	public SplashItem(long splashId, long enabledTime) {
		this.splashId = splashId;
		this.enabledTime = enabledTime;
	}

	public SplashItem(long splashId, Calendar enabledTime, String eTag) {
		this.splashId = splashId;
		this.enabledTime = enabledTime.getTimeInMillis();
		this.eTag = eTag;
	}

	public String getUrl() {
		return url;
	}

	public void setUrl(String url) {
		this.url = url;
	}

	public long getEnabledTime() {
		return enabledTime;
	}

	public void setEnabledTime(long enabledTime) {
		this.enabledTime = enabledTime;
	}

	public long getSplashId() {
		return splashId;
	}

	public void setSplashId(long splashId) {
		this.splashId = splashId;
	}

	public String geteTag() {
		return eTag;
	}

	public void seteTag(String eTag) {
		this.eTag = eTag;
	}

}

2）Dao中的代码

	@Query(value = "select new com.cvt.smarthome.application.advertisement.entity.apiEntity.SplashItem(t.id,t.enabledTime,t.eTag) from SplashSetting t where  t.terminalType.id=?1 and t.appkey =?2 and t.resolutionWidth =?3 and t.resolutionHeight=?4  order by t.enabledTime  desc ")
	public List<SplashItem> find2LastSplash(Long terminalTypeId, String appkey, Long resolutionWidth,
		Long resolutionHeight, Pageable pageable);

注意：
a)@query中的SplashItem必须带上包名
b) Dao 中的new com.cvt.smarthome.application.advertisement.entity.apiEntity.SplashItem(t.id,t.enabledTime,t.eTag)和java类对象中的构造函数 public SplashItem(long splashId, Calendar enabledTime, String eTag) 对应。
