Question

SSH，JSON。为什么我把那部分注释掉，页面就有返回，取消注释，页面就什么都没有..

或者能不能告诉我有什么办法能将后台数据传到前台的js中，list<user>类型

/*private StatisticsServiceImpl statisticsServiceImpl;

public StatisticsServiceImpl getStatisticsServiceImpl() {
return statisticsServiceImpl;
}

public void setStatisticsServiceImpl(
StatisticsServiceImpl statisticsServiceImpl) {
this.statisticsServiceImpl = statisticsServiceImpl;
}*/

private List<Tbdetail> detailList;

public List<Tbdetail> getDetailList() {
return detailList;
}

public void setDetailList(List<Tbdetail> detailList) {
this.detailList = detailList;
}

public String countByProvince(){
detailList = statisticsServiceImpl.countByProvince();
for (Tbdetail tbdetail : detailList) {
System.out.println(tbdetail.toString());
}
return "list";
}

<package name="json" extends="json-default" namespace="/">

<action name="jsonss" class="statisticsAction" method="countByProvince">
<result name="list" type="json"></result>
</action>
</package>

前后台是通过http 协议交互的，最好能先熟悉http原理
